Inside Xbox One: the interview with Brad Wardell and clarifications on DirectX 12

GDC 2015 will truly be an event not to be missed. Microsoft will show a lot of interesting things on the PC as on Xbox One. Cross-play future games, cloud computing, DX12 work on Xbox One and more.

The prolific boys of The Inner Circle have released last week, more precisely Saturday, February 7, a tasty interview talkative Brad Wardell, Stardock boss, software house very operational in respect of the 3D engine and development tools for video games...

[ThinkThink]

Great interview and very informative. I expect two weeks worth of news articles to come from this on n4g.

[Software_Lover]

2 weeks........ You obviously haven't been here long.

I say a full month.

[xx4xx]

....and since it's Microsoft, regardless of content, nobody will read the articles but will still post negative comments.

[JMyers]

So negative comments are reserved for MS only on here?

[UltraNova]

Hmmm I can recall just from the top of my head about 155 negative pieces JUST for the order 1886 let alone the whole ps4 ecosystem.

JMyers, let it go dude.

[MadLad]

I'm sure Gaming Bolt will pick this up, slam their hands against the keyboard for a couple minutes, then make about ten articles on this one interview, spanning about 14 pages each.
One or two sentences per page, of course.

[user5575708]

hmm he states that with dx12 the 900p issues should end. maybe fans can finally stop getting the short end of the stick now

[UltraNova]

Yeah you are right its about time PS4 owners stop getting the short end of the stick by this parity bullshit. See what I did there?

Both sides will benefit if indeed DX12 makes a tangible difference.

[Automatic79]

Inner Circle is truly for the Xbox community I love it.

[BallsEye]

rather a month of articles saying how xbox one is weak and how dx12 does nothing. Just to cover up the good news.

"In short, Wardell says openly that the use of old engines are limiting especially on Xbox One, a hardware "different kind" (perhaps because it was designed with DX12 in mind?) who struggles to support tool not modern. Hence the resolution-gate"

this.

[NerdStalker]

"rather a month of articles saying how xbox one is weak and how dx12 does nothing. Just to cover up the good news"

We've had a few years of you blabbing on about how you hate ps4.

[kevnb]

That hurt my eyes, ancient frostbite 3 engine... Come on.

[Cherchez La Ghost]

In a nutshell for those who don't want to click for the article...,

In summary then:

-Xbox One launched ahead of schedule, to avoid giving too much advantage to Sony PS4 with which he had already planned everything in detail, however, being the result of a project, however old, closer to the PC market than on the console.

-Xbox One was deprived of adequate tools and APIs. Just think that only recently with the arrival of the latest DX 11.3 and new development kit has arrived to have titles of a certain thickness (2 Forza Horizon, Sunset Overdrive) and many identical counterparts for PS4. Why Ryse is, today, one of the titles most impressive technically? Because of CryEngine, as well as for proprietary tools Microsoft, such as FH2 and 343 Industries (have seen Halo 4 on One?).

-One APIs are anything but low-level, and still trudging to exploit adequately the console hardware.

Hmm, I guess DX12 was the reason for MS slogan "Built for the future" slogan back in '13. I hope we can see some more at GDC coming up.

[mkis007]

Ryse isn't technically impressive, just visually. No physics system and when you swing your sword it goes through the environment, the world around you doesn't know your there. Saved a lot of performance by leaving those out. I bought it for the setting.

[TheRedButterfly]

The technical hoops that Crytek had to jump through in order to achieve such graphical capabilities on the less-than-low-level API the XO had at launch are the impressive technical aspects.

[Software_Lover]

I said it when the Xbox One launched that it only launched when it did because Sony caught them off guard.

I was of course disagreed with and bubbled down but whatever. N4G doesn't affect my real life lol.

[gangsta_red]

Yes, I am starting to learn a lot about how this bubble system truly works.

It was pretty obvious that the Xbox One was launched way ahead of schedule and for that matter even Sony's PS4 to a lesser extent.

But the X1 most definitely, we can see with the all the updates and even DX12 coming so late in the game. I wonder just how early MS had to launch Xbox One and what was their original expected launch date?

[jhoward585]

Good read.
Based on this article, tiled resources is the key to making DX12 work more efficiently. The reduction of textures memory size sent to the ESRAM will help in a big way. I guess that what the decoder LZ77-compression suppose to do.

[halfblackcanadian]

I think the speed of GDDR3 will utilize this API well, but I think Azure processing is where the tiled resources will shine

[JackBNimble]

don't you mean ddr3 ?

[halfblackcanadian]

@JackBNimble
Sure, yeah. Sorry.

All I'm saying is that the faster RAM will make good use of all the draw calls and such going from CPU to GPU

[UltraNova]

@above

If you increase the speed limit(i.e draw calls)on the highway that leads in the city (i.e GPU) while the city's entrance (GPU controller)speed limit cannot be changed will the number of cars that get in the city increase? No you will end up with a bigger bottleneck.

If we assume that the bandwidth and potential draw calls are underused then yes we might see some increase in performance but as we all know console coding is already close to metal meaning that most of the data that can be sent to the GPU are already been sent.

I'm not saying it wont help the XB1 on the contrary DX12 will make it more efficient in running a better optimized code but it will not do miracles some people are so naively rushing to believe.

[senis_kenis]

Textures are not sent to sram, they are directly fed to gpu tmu's from ddr3. Render targets or most of them are in esram and dx12 will not fix small sram size, low resolution or inferior gpu. Even microsoft admitted that dx12 will have low impact on xbone, most gains will be on pc. And forget about tiled resources being exclusive to bone, ps4 has it too it just called differently - Partially Resident Textures (PRT). It has the same GCN based GPU remember? And by the way prepare your self for halo an QB at 720p, MisterXMedia brainwashed poor souls.

[LoydX-mas]

Funny,
its as though you didn't read the article at all.
-the Xbox One is dual lane and has two graphic compute processors and two command compute processors......something the PS4 clearly does not have. So the "inferior" GPU argument is not relevant, it is a GPU built specifically for DX12 and the benefits it will bring.

OR- do you honestly believe that MS built a brand new gaming console at the same time they were developing a new API(DX12) and forgot to make the console take complete advantage of the new API?? It is called Xbox because of the original name DirectXbox.

[No_Limit]

Great find LoydX,

DON'T forget that MS spent over 3 billion Benjamins to have AMD to built them the custom GPU chips and no doubt all the dominos will fall when DX12 and Windows 10 arrive.

[TheRedButterfly]

@4.2

You know, I always kind of hoped that your breed of fanboy would actually be willing to... you know, acknowledge when a fact had been presented to you...

What a fool I was to think that you'd be willing to deviate from your agenda, even when you know what you're saying is a straight-up falsehood. *sigh*

[senis_kenis]

@LoydX-mas ps4 has 2 gcp's and 8 ace's, while xbone 2 gcp's 2 ace's. Stop commenting on something you don't have clue about. This thread has gone fool retard, keep waiting for secret source... xbone gpu is inferior in every way. period. No api will fix that, because ps4 can already do everything dx12 will offer via GNM.

[Dewitt]

Dual lane versus single lane which is what I was talking about back when the specs were revealed. Since it can both pull and feed information if DX12 took advantage of that it would be able to increase the bandwidth of data sent through the GPU calls. Since this is basically revealed in the AMD talk, it shows that the XB1's optimization tools are not able to be properly leveraged. Can't wait for GDC to hear their plans.

[LifeInNZ]

Basically we have yet to see what the X1 can fully do. Well, as always I will let the software do the talking so I await eagerly for the next gen releases on X1. Just no more screen tearing and framerate drops please developers!

[u got owned]

Agree, at this point we are hearing lot of good things about DX12 and XBO but all we can do is wait and see if all this talk is true.

[gangsta_red]

This is what it basically comes down too. All this is well and good but I would like to see it applied to the games.

Until I see actual use then I'm going to hold back my excitement and enthusiasm. Hopefully at GDC we will get further explanation and come E3 actual full on games using this tech.

[MSBAUSTX]

The article said it wouldnt be released to third parties until November of 2015. We probably wont even see any real gameplay from a Microsoft studio created game at E3 if that is the case because of the timeline of the release.

Phil played down DX12's capabilities for the XB1 because he knew it would give a %10 to %20 increase to current software on XB1 at the launch of DX 12 and he didnt want the hype train to be full steam ahead for something so small. This would point more to 2016 before we see any game really built around the benefits of DX12.

Definitely wait for GDC but dont get your hopes up for something amazing this year at E3 using this new tool. It is very encouraging to see exactly how all of this is starting to play out and How MS is getting all their ducks in a row. Going to be a very interesting 18 months. I enjoyed this article. Finally some credible and realistic light shed on this subject.

[JorboTron]

Phil understands gamers. Under-promise and over deliver. You go the other way and gamers will eat you Alive.

[christocolus]

" The GDC 2015 will truly be an event not to be missed. Microsoft will show a lot of interesting things on the PC as on Xbox One"

cant wait to see some good looking stuff at the show. i just wish they'd show us scalebound , gears4 or even snippets from rares upcoming game all running on this new api.

Also the Xbox One DX12 team will be doing a podcast with the inner circle very soon. according to a tweet by the innercircle, the dx12 team have plenty to discuss about the api and xbox one.

[halfblackcanadian]

Don't get me wrong, I'm loving these guys (and XboxMAD) but where in the hell did they appear from? Seriously. They seem to get nothing but big deal interviews on the regular. It has quickly become one of my go-to sources.

[christocolus]

lol. I totally understand you bro. they've been doing some stuff for a while now.but they got alot of attention after scoring an interview with Phil Spencer.i think that opened the doors for them i.e Ken Lobb, Brad Wardell and soon Dx12 Xbox one team and Aaron Greenberg. They are also very active on twitter and listen to what xbox fans have to say.they regularly take user feedback and use them as major points for discussion with Xbox execs. In general they always ask the right questions during their interviews .They are doing a great job.

[RiseofScorpio]

E3 my friend. The day that Gears of war 4 and Banjo Kazooie are announced will be a glorious one.

[christocolus]

im ready

[MSBAUSTX]

I bet those games have been held back and no concrete release date or gameplay shown because they are being developed using this new tool and they are waiting for it to release along with Wibdows 10 before they show us what those games look like. The potential this has for Halo 5, new GOW, and Scalebound is very exciting. No doubt PS4 has unlocked potential as well but MS is starting to make my XB1 look more interesting with all of this news.

[DragonbornZ]

Really starting to like The Inner Circle. Lots of info and detail in their interviews.

Also "Another very important cue, always came out of the interview, is that Wardell has hinted at a "play down" by Phil Spencer to dampen the enthusiasm arising from the DX12 on consoles"
;)

[LexHazard79]

Inner Circle Podcast is awesome. They get the interviews with the top dawgs at Xbox and devs. They got some other great interviews lineup... sub em on YT.

[RiseofScorpio]

Yep their Klobb interview was great. The upcoming A.Greenberg one will be great too.

[XBBB]

Sounds great,DX12 will give the XBO a massive boost in performance and visual quality.
I guess the "secret sauce" is real after all,and explains why the GPU is custom built.

[Bigpappy]

The theoretical feature improvements with DX12 are vast and varied. It is obvious the the X1 will receive considerable benefits.

I want for M$ to tell me about all the benefits and features coming to X1, PC, tablets and phones, then show me at least some some demos using said feature sets. I eagerly anticipate GDC. Really hope I am not left with more theory and no prof of concept. I am sure its all real (Intel, NVIDIA, and other think it is a huge deal). But I like to see for myself.

[Moldiver]

"And what Wardell said in the interview? With DX12 the bottleneck will not be the CPU, but will be the GPU, since they have only one channel (GFx core / CCP). This is true of PC cards (current) and PS4, but not on Xbox One.

Reason? Dual Lane. Xbox One as you well know (we repeat endlessly, but it's good to talk about it) has two channels and two GFx core Compute Command Processor, that "communicate" via HSA with two distinct groups of Cumput Unit (6 × 2 = 12 CU)."

So XB1 is HSA complient? GDC should be interesting this year.

[XBBB]

Seems so,HSA complient and custom built GPU,or maybe the GPU inside the XBO is the first DX12 card which AMD designed and most likely are going to use the same technology for there upcoming cards this year.

[christocolus]

May be at GDC we will finally understand why MS and AMDs Xbox One Gpu deal cost $3Billion.

http://www.vg247.com/2013/0...

Edit

@XBBB

My thoughts exactly.I think alot will be revealed at GDC.

[XBBB]

3 billion wasn't spent on a less powerful GPU,why would Microsoft spend more money if they wanted to they would of chosen the same GPU as the PS4,so why did the spend 3 billion.
The answer is DX12 and what they had planned for the future, unfortunately Sony caught them off guard and the XBO was released 12 months to early.

[TheCommentator]

I'd been saying this forever:

Theoretical performance is a number on a sheet of paper. Last gen, PS3 was TWICE as powerful on paper but struggled to stay on par with 360. Matter of fact, for at least the first year, the graphics comparisons always showed 360 games looking better than PS3. It wasn't until Sony reworked their api that they got up to the same level as MS. Ironically, the PS3 had no good exclusives within that time frame as well. Does this sound the same as what fanboys are bashing Xbox One for?

Here's my point:

The theoretical difference between the two new consoles is roughly the same as last gen, again favoring Sony on paper. Microsoft needs to change their api to improve their performance to, in my opinion, get AT LEAST on par with PS4's real world output (after all MS did just that last gen). I wonder what we will argue about when that happens???

[strangeaeon]

It will still be argued because fanboys lie to themselves.

[ENSABAHNUR]

Hopefully actual important issues like no more locked DLC, no more exclusive to specific console DLC, etc... But we that have brains know the sheep will still get caught in the same fence and the same trolls will follow and then have their way with them... A bit too creepy of an analogy I know but I guess it works

"And what Wardell said in the interview? With DX12 the bottleneck will not be the CPU, but will be the GPU, since they have only one channel (GFx core / CCP). This is true of PC cards (current) and PS4, but not on Xbox One. "

No 2nd bus?

Hmmm.. that's not what Mark Cerny stated

"First, we added another bus to the GPU that allows it to read directly from system memory or write directly to system memory, bypassing its own L1 and L2 caches. As a result, if the data that's being passed back and forth between CPU and GPU is small, you don't have issues with synchronization between them anymore. And by small, I just mean small in next-gen terms. We can pass almost 20 gigabytes a second down that bus. That's not very small in today’s terms -- it’s larger than the PCIe on most PCs!

"Next, to support the case where you want to use the GPU L2 cache simultaneously for both graphics processing and asynchronous compute, we have added a bit in the tags of the cache lines, we call it the 'volatile' bit. You can then selectively mark all accesses by compute as 'volatile,' and when it's time for compute to read from system memory, it can invalidate, selectively, the lines it uses in the L2. When it comes time to write back the results, it can write back selectively the lines that it uses. This innovation allows compute to use the GPU L2 cache and perform the required operations without significantly impacting the graphics operations going on at the same time -- in other words, it radically reduces the overhead of running compute and graphics together on the GPU."

Yup no 2nd data channel..LMAO

Who are these people trying to fool?

[Dewitt]

A second bus is not what the article is describing, it adds a second lan. So it can both feed and receive information simultaneously. A second bus channel just allows for information to fed through that single lane.

The PS4 uses OpenGL and will not receive any benefits from DX12. Therefore, Cerny futureproofed his console according the OpenGL roadmap.

[headblackman]

this this kind of information coming out about the xbox one and how it's validating what xbox fans have been saying all along and have been taking unnecessary flack for, what are we as gamers willing to do to rectify this wrong? (not as playstation fans or xbox fans, but as gamers). my suggestion is to finally get back to gaming and leaving this resolution and power crap alone and just to let get back to letting it be about the games and features alone.

im looking forward to the day where we can just talk about games in a games forum again.

GAME ON!!!

[WESKER2015]

the hype is real, Lol

either way i can't wait to see what DX12 brings to PC and Xbox One

[Kingdomcome247]

I'd be lying if I said that understood anything within the article. What exactly is HSA? Why is it a big deal? What is with the thing he mentions that the Xbox One has two of, and is the only console to have this? Hopefully at GDC they have a translator present that will translate everything into layman's terms for guys like me.

[turdburgler1080]

Here's a link about HSA. http://developer.amd.com/re...

[Kingdomcome247]

Thanks man. I googled it too, and I don't fully understand it but I'm very interested to see everything at GDC.

[jhoward585]

Tech talk can be a bit confusing to some so I'm going to explain what HSA is.

HSA help speed up computation between GPU/CPU/RAM. One of the main function of HSA is to write the data once instead of the same chuck of data sent back and forth to the CPU/GPU/RAM over and over again. This reduce communication latency between the CPUs, GPUs and other compute devices.

With out the HSA compute system embedded in the hardware the GPU/CPU will run on separate data lanes. The HSA makes it so that the GPU/CPU/RAM shares the same data bus lane.

Hope that helped.

EDIT: all you have to know is HSA bring the GPU/CPU/RAM together on one data bus lane which will give it a huge increase in computation.

[Kingdomcome247]

Thanks man, I appreciate it. One more question. If HSA is primarily for reducing latency and unifying gpu/cpu commands into one lane, what is he mentioning in the article about the two lanes the Xbox One has that are significant and unique?

[jhoward585]

@Kingdomcome247
You're welcome man.
what is he mentioning in the article about the two lanes the Xbox One has that are significant and unique?

Its a another compute system design to talk to the memory more efficiently. One channel help reduce latency by increasing the bandwidth of the DRAM memory. The other channel speed up the read/write data processing to the RAM.

Well, according to this article, PC's gpu and PS4 have one data channel while the x1 have two channels. This means that the PC/PS4 will have to do everything on one channel while the X1 can separate the data compute process on two separate channels. This will give the x1 hardware an advantage over the PC/ps4 when writing codes for a game. The codes themselves can be written much simpler than ever before b/c of this.

[joeorc]

And its not true:

[Lenrulesdaworld]

wow, whoever post the article thank you, we appreciate the compliments and will continue to bring you guys great news. We really are trying to be your voice, we don't get recognized for our content to often but trust me, we are more than a podcast. thanks guys and keep looking out for real reviews and pod/vid cast content.

[halfblackcanadian]

Your team has gone from 0 to legendary in very little time. Keep it up.

[Go_Go_Se7en_30]

Good stuff man, this is a hot topic. Definitely will be tuning in ;)

Btw, make sure you set your alarm clock next time. Ppl were foaming at the mouth waiting for their fix. Lol

[Lenrulesdaworld]

LOL will do, my bad lol

[smoothop]

Think I remember Phil saying its not a sprint, but a marathon. Damn so true, always had faith that the Xbox was built for the future.

[dreadz74]

The truth is slowly coming out now!!!XB1 DX12 team is goin on the podcast soon to discuss DX12 on XB1.Now if there are no gains what is to discuss?Can't believe some ppl still believe this will have no effect on XB1 or that only a 20% increase...They knew what they where doing when they built it and evidence points to them having to release early why would they launch without DX12 otherwise..GDC will be epic indeed!!!!

[halfblackcanadian]

I can't help it, I'm super excited for MS this year. New Surface Pro, new flagship phone device (possible from HTC and Samsung as well), Windows 10, Hololense (at least further details), DX12 stuff, exclusives.....I can't even.

I have no idea what's happening on the PS4 or WiiU front, but that's because I don't follow them. I can't imagine it's anything this exciting though)

[Cherchez La Ghost]

It makes sense now when stated that the X1 was released a year early. MS must have known they were going to take a hit against Sony for this. Thanks to your boy Don Mattrick for the bad start for the X1. But now, MS has done nothing but monthly updating and listening to consumers of what improvements we want to see. But that Windows 10 Presentation caught me off guard of what DX12 will do for PC & X1 gaming. I'm ready to smacktalk and make some new PC friends. LoL!!

@turdburgler1080

Thanks for that link to AMD breaking down what HSA is all about.

[GenuineGamer]

So XB1 is actually the more powerful console after all. lol

[joeorc]

and the fish puffery continues from the last cycle to this generation

Well the ps3 is only more powerfull on "paper" while the xbox360 in reality is the more powerful system..

And yet again here we are again, the Ps4 is only on "paper" to be the more powerful system. While in reality the xbox one is not only on par but in reality is the more powerful system.

The blunt truth:

Trying to frame the Argument based on mythology may net you some people to agree, but it ,is what it is, not what the real truth is. Its just that a perception of a truth based on a Myth to be true. Not what the truth really is.

[Mkai28]

Well, well, well, what a surprise.. Nothing but praise for the Xbox one, what's this, on a site non other then N4g? It appears that ppl got a scent of that "secret sauce" and now they're stomachs are GROWLING FOR A TASTE!!

Seriously, I remember the quote from Major Nelson " I cant wait for the truth to come out!"

[GenuineGamer]

THE TRUTH ALWAYS COMES OUT IN THE END! :)

[magiciandude]

Xbox One is starting to really shine, and their exclusive lineup for 2015 looks stellar. Us Xbox One gamers are in for a serious treat.

[MCTJim]

I have said it wayyyy back when they were talking specs and performance. We dont know what all the extra chipsets were in the xbox one. Only what DF could figure out and they even said we dont fully understand. I was bubbled down when I posted how is this trolling? I feel redeemed regardless if I have only 2 bubbles. The truth does come out eventually. I am excited again about seeing what this console that was built for the future is all about!!

[GenuineGamer]

I added a + to your bubbles for you. Hope you get back up to 3 :)

[richie007bond]

+ bubble voted added my friend

[Automatic79]

I always felt the Xbox had much more under the hood the problem again goes to the media downplaying the ability the Xbox One has. MS keep pumping out those fantastic games looking forward to seeing those beautiful games in the future.

[3ndulg3]

I'm just happy Microsoft is proving the other people wrong.

[Lennoxb63]

I've been saying all along that the X1 has a lot more in store than what has shown up on the surface. But of course I get flagged and down voted to all hell. Good job MS. Can't wait for GDC and E3.

[MCTJim]

join the club, I agree with you 100%.

[cruzngta]

Looks like the XB1 may have the last laugh and surpass the PS4 for overall system capabilities/power. I also remember Major Nelson saying back in 2013 'I cant wait for the truth to come out.' They knew about this way before us inhouse but had to sit back and take alot of crap which I am sure was aggravating for them knowing all along what their machine could do once fully utilized properly. I am glad to see this and now all the haters and naysayers can sit back and be mad at the world. We are in store for some amazing content going forward.

[joeorc]

I cannot wait for the people in this thread to post in ps4 centric threads downplay the ps4 good news:

One poster made a really good quote:

"I've been saying all along that the X1 has a lot more in store than what has shown up on the surface. But of course I get flagged and down voted to all hell. Good job MS. Can't wait for GDC and E3."

Here maybe remember that when someone does this!
I've been saying all along that the ps4 has a lot more in store than what has shown up on the surface. But of course I get flagged and down voted to all hell. Good job Sony. Can't wait for GDC and E3.

If you do not want that thrown in you face , maybe do not say anything at all. Because this thread is pure gold, on Hippo cratering, let alone all the AstroTurf that will follow being posted on N4G. About how the real truth of the "ps4 is not the powerhouse" its really the Xbox one..when months after months all we heard power does not matter. Its the games that matter.

And yet all last generation, the same story. This is a trend I'm seeing its not about the console, its about taking playstation gamers down a peg or two. But the ironic thing is the Xbox and Nintendo gamers are just as worse as the playstation gamers.

True gamers , you know the ones before game console that played board and RPG games. Are laughing their @S's off at all this.

[thexmanone]

Then there are the people like you who come in hear to try to stir up the kiddies. Why judge other peoples comments? People do have a opinion to say what they want.

[joeorc]

I never said they do not have a right to an opinion, I am pointing out that certain claims better be able to be backed up or its going to be called out on the BS that i it is:

Example:

Than there is threads like this trying to pass off missinformation as fact's, no dual data channel in the ps4?

"First, we added another bus to the GPU that allows it to read directly from system memory or write directly to system memory, bypassing its own L1 and L2 caches. As a result, if the data that's being passed back and forth between CPU and GPU is small, you don't have issues with synchronization between them anymore. And by small, I just mean small in next-gen terms. We can pass almost 20 gigabytes a second down that bus. That's not very small in today’s terms -- it’s larger than the PCIe on most PCs!

"Next, to support the case where you want to use the GPU L2 cache simultaneously for both graphics processing and asynchronous compute, we have added a bit in the tags of the cache lines, we call it the 'volatile' bit. You can then selectively mark all accesses by compute as 'volatile,' and when it's time for compute to read from system memory, it can invalidate, selectively, the lines it uses in the L2. When it comes time to write back the results, it can write back selectively the lines that it uses. This innovation allows compute to use the GPU L2 cache and perform the required operations without significantly impacting the graphics operations going on at the same time -- in other words, it radically reduces the overhead of running compute and graphics together on the GPU."

but yet everyone claiming as sucn gets a d@mn free pass when it is not the truth?

Get real. At least im not the ones trying to pass off diatribe off as a fact , such as that as a means to "stir up trouble" as you said. Maybe to avoid such trouble, the people doing such may be better off doing some more research before making such a claim and than trying to pass it off as a d@mn fact!

[jhoward585]

What you fail to realize Mr joeorc is that X1's compute system and hardware features are theoretical on paper. So, a lot of those features are still in the testing phase with MS new API(dx12). This is probably the reason why we haven't seen any proof of the X1's power. Well, Once Dx12 is completed we'll see the real potential x1's processing power.

Plus, keep in mind that MS's engineering blue print for the x1 were stolen when they got hacked. The hacker who stole those engineering blue print could've grabbed the old(early version) x1's engineering hardware designs. That could explain why everything I've read on this article is slightly different from what I've read on other sites in the past. That just a theory of mines.

Anyways, The truth of the matter is that we're finally getting some true insight about Dx12/x1 from an expert(brad wardell)

So you're the one that is wrong here...

So N4G....

Looks like MisterX was onto something after all. Not dual GPU but dual lane GPU.

HSA compliant - he's been saying that as well for yonks.

Tiled rendering, NOC and DX12 improving CPU output. balanced system - been saying that as well.

I got banned from his blog for questioning him but always said I'd apologise If I were wrong. I might be doing so soon.

N4G, GAF, B3D, EG and every bloody sony fan on here it might be your turn to apologise soon...

Lets see if you do.

So glad I bought an X1 Day One. Cracking machine.
