iGG: We haven’t heard much of the PlayStation 4 since its announcement last month. At their GDC conference, Sony went into great detail about the hardware packed inside the console.
Could someone explain to me in layman terms what this means for game development tech wise?
low end CPU, low to mid end GPU. 8GB of RAM is great, but I would rather trade 4GB of that for better CPU/GPU
i don't think that a fair way of putting it. when compared to pc's consoles always have and always will be low to mid. a console that can preform just as well or better than a high end pc will have to become a pc in its self thus defeating the purpose of a game console in the first place. compared to a pc of the same price range the ps4 does indeed have great specs (assuming that the ps4 will be cheaper than ps3 at launch).
The CPU is really a high-end tablet CPU, but low-end when compared to PC standards. 8-cores helps somewhat, but it's still low-end, which is okay for a console since it's not running tons of programs like Microsoft Office, After Effects, and other music, video, or image editing software. And it doesn't use a OS with a large print like Windows. The GPU is mid-range and will pick up most of the slack for the CPU when it comes to games and other task. 8GB GDDR5 RAM is amazing, and means loading will be minimal, textures will be HD, and more environmental items (trees, gravel, etc...) and effects will make games look that much better. @AnyaShroud How do you expect them to improve upon the GPU? It's borderline an HD7970m which is currently AMD's best mobile GPU on the market. The only way to improve would be to build a custom mobile GPU (which would raise the price of the console significantly) or go with a traditional GPU 7870+ which would turn the console into the size of a desktop. I agree the CPU could be better, but the GPU is the best they could do for the price and size. I 100% back the GPU.
Windows hasn't had a large footprint since Vista... Win7 and 8 both have substantially lower footprints... 8's kernel is smaller then the current Linux kernel
RAM is not just for games, all the social + web surf + other stuff will need RAM as well, that's why PS4 will ship with 8GB of RAM and even if they bump'd the Specs = put a better GPU in there, lack of RAM would limit the more powerful GPU + all the non gaming stuff would take resources to the gaming side.
a) i7 does not run 8 HW threads 4+4 hyper threaded with performance dropping steep after 6+ threads (in real world scenarios i7 saturates at 4, gets minor benefit in non memory intensive application up to 6 (around +20%) and drops off fast after neglecting any benefit when reaching 8 threads). Neither does AMD's 8xx0 (8int, 4float), btw. b) bottom of high end cards rather than low-mid. But yeah, sure we are defining 3x XFire/SLI high end now, right? 2+GB 7850 is beyond $200 these days and plays most if not all games just fine in 1080p today.
I said it and yet again nobody listened to me- The CPU isn't a native octo core. It is indeed just two quad core Jaguars bolted together, hence the 2mb cache per 4 cores. 2 x 4 cores. It won't be as fast as a custom native 8 core. The GPU is alright but it won't be blowing anything decent away on PC by the time PS4 does arrive.
This is irrelevant. 2x4 cores which run 8 threads is 8 cores running 8 threads. The only problem this setup has, is that it has 2 cache areas which are non coherent. Which again is irrelevant because it runs a 176GB/s GDDR5 RAM interface. Worst case scenario is a context switch from "block a" to "block b" has to go accros GDDR5. We know nothing about cache line locking or what else the OS can do to prevent such a scenario (e.g. lock cores to threads). It indeed has 8 cores running 8 independent threads unlike any currently known desktop CPU.
I don't know why people still bring this up. Even PC developers have said that's the consoles don't have to as high end as PC's because they don't have to be. They're able to get the most of it. Take the same PC and GPU in the PS4 and put it into a PC and see if they get the same performance. You need an Overly Powerful PC to run games like Crysis 3. If you took the CPU and GPU from a PC that runs Crysis 3 on ULTRA and put it into a Playstation it would produce visuals a multitude times better than what Crysis 3 is outputting. Because the closed system of a console will allow developers to get the most out of the CPU and GPU.
It isn't irrelevant when you have non coherent cache linked to high latency GDDR5 memory optimised for graphics hardware....citing main memory bandwidth is what is irrelevant when it comes to CPU performance! CPUs don't require hugh bandwidth. They require low latency access, which is precisely what the point of on die cache actually is- reducing the amount of times the CPU has to 'fetch' off the die from much 'slower' (high latency) memory. Lets face it, the CPU is a bit pisher than it would have been had it been a native octo core. Not really significantly more, but I was right. Againzzzz........ I wish the guy who banged on about HSA crap to me forever was here to answer why the chip is clearly less integrated than your average ARM based smartphone. AMD dumped what they had on one die with minimal reworking. It wasn't complicated. It is a cheap way of making a decent console. Sony want the costs to be low, that is plainly priority here. Its all about the costs to manufacture people, Sony aren't going to break the bank on this machine like they did with PS3. Oh and yeah, Win 8 comfortably runs inside less than a gigabyte of RAM. Its a major fallacy that Windows is some giant memory hog for games.
^^ you referring to me? This coming from someone who instead of having a civil conversation threw words at me and blocked me not giving me a chance to respond? How do you have that many bubbles is beyond me. But some people sure like what you have to say. It sounds smart but doesn't really go beyond the usually crap. I actually agree more often with you than not, but it's kind of weird that you can't handle critics well.
"Windows hasn't had a large footprint since Vista..." Having 2GB of resources tied up is pretty heavy imo Processor: 1 gigahertz (GHz) or faster with support for PAE, NX, and SSE2 RAM: 1 gigabyte (GB) (32-bit) or 2 GB (64-bit) http://windows.microsoft.co...
Nevermind Ju he has no clue what he is on about most of the time. Comparing a Tablet CPU to a Desktop CPU and cheering at the cores is laughable at best. AMD has 8 cores on their Desktop CPUs, The same 8 cores most of the time get beaten by 4 Core Intel CPUs even in heavily threaded applications, its barely a contest. What would make you think 8 tablet cores would stand any chance then? Its funny how desperate Ju can sometimes get to defend whats going into PlayStation hardware. In anycase Ju, if the PS4 CPU/GPU are so good why are games like BF4 being planned for 720p. Looks like Low to mid range PC settings to me.
Agreed. A console doesn't need that much ram. Especially since it is high latency GDDR5 ram. Good for GPU, but bad for CPU. The CPU isn't even fast enough to really use all of that ram efficiently. I feel like because of the bottleneck of the PS3 being its' limited RAM, they wanted to make sure it wasn't their worst enemy again. So they over compensated with the RAM, creating two other bottlenecks. The CPU and the GPU. Oh Sony. No doubt you're going to have good games, but can you please balance your consoles?
@ABizzel1 If you really think the GPU is from the 7900 series keep dreaming. It's a mobile version, same features, less bandwidth, and... you know what, you can't even compare it to a fully fledged 7900 series GPU at all.
@stragomccloud Completely agreed. The 8Gigs of RAM is more of a marketing stunt. Ms had it so Sony decided to include that since RAM is cheap and people tend to see these figures. As to a lay man RAM can mean alot when deciding on hardware. Its a known fact even today most PC games barely consume 1.5Gigs of VRAM even when running at 1080p. Now all the 8Gigs wont be going to the game that understood, the break up might look a bit like this: OS: 1-2 Gigs Game: 1-2 Gigs. This would leave anywhere between 4-6 Gigs for the VRAM. Its already known the next KZ SF is known to only use 1.4Gigs of VRAM. Why dont Sony use more of it? Simple fact is its the GPU that becomes to bottleneck, Hell even the RAM speed would probably end up becoming a bottleneck if more VRAM was used. Hence i would think Sony did go overboard with the RAM, It was most like a marketing stunt in order to look on par with MS and most likely games wont be using more than 1.5-2gigs as VRAM.
Low end CPU low end GPU 8gb ram lolol. Talk about a crappy computer; thats all consoles are becoming more and more like computers. They may as well become desktops next gen to avoid all the confusion. 'Entry Level' gaming desktops.
Anyone who thinks that the 7850 is a low or even med range card is either very arrogant or just plane stupid. You can run most games on high or ultra with a 7850, maybe not with crisis3 and a few other select games. The ps4 doesn't need to be a supercomputer to run games at the 7850 level. Hell, I only have a 7770 1gb gddr5 and 8gb of ddr3 ,and I can still run all of my games on high or ultra, granted I may not be running at 60 fps , but 30 fps with no slow down still looks pretty dam good if you ask me.
You clowns never fail to amaze me with these pointless arguments on the internet.
They're custom built and games/software can be optimized right down to the metal. You can't optimize games the same way on PC. Consoles DON'T need to match high-end PC specs. I don't know why PC fanboys feel so insecure that they need to downplay the PS4 all the time.
Here's a good example of 4 core Intels, beating 8 core AMDs in gaming. Sorry but AMD just hasn't been able to make an efficient CPU architecture since the K8(10 years ago) AMD, "Always MeDiocre"
sure you can call the PS4 low end everything but as KZSF has shown it gets its job done pretty well and from the gameplay footage shown of it, there's nothing "low end" about it and try coming in here and say otherwise and you'll look kinda dumb! Sony never said that the PS4 is aiming to be a high end gaming machine, right? so why are you people ditching it and compare it with current top of the crop PC GPU when stats from steam shows majority of pc gamers only have mid-range PCs! what funny is, many of you guys here sound like you know how to actually design a better console than Sony when all you do is just buy pc parts and put them together! there's no "designing" part of what you do so just don't try to sound too smart over here like you know everything! in the end, it comes down to games and like the PS3, people were saying the 8800GTX circles rounds over it but have you ever successfully play any Sony made games like Uncharted, GoW, GT5 etc on it? will it play The Last of Us? can your pc with triple SLI GTX680 or XFire HD7990 play them too? same goes for the 360. have your uber PC able to play Halo 3, Reach & 4 yet? what about Gears 2 and 3? I don't think so! yeah...Wii might have already been successfully emulated and then some but there's still none for PS3 and 360 and the next gen is already upon us! so, this just shows that power is not everything and it's definitely nothing to discount the PS4 for! as far as we know, the PS4 is already a huge step forward from the PS3 in the right direction! knowing Sony, games not available on PC are definitely coming! A LOT OF THEM! THAT alone make the PS4 worth it!
You guys know absolutely nothing about how hardware works together. Just because an Intel 4 core beats an 8 core amd means nothing as the is purely limited by both the windows os and that developers cannot pinpoint specific cores or pairs of cores because there is no same PC on the market that are identical. Also the fact that the ps4 is an apu removes so many bottlenecks between ram,CPU & GPU that has plagued the PC market for years.
didnt know there are so many experts here. ya know. you guys should go work for MS or Sony. instead of wasting your time arguing here.
I have bubbles because I just have common sense Ju. @Ju The fact that I blocked you, was between you and me and not really necessary to be made public. Your motivations for making it public show the world exactly WHY you would be someone worth blocking, because you'll only rabbit on pointlessly, wasting my time, even when you have been shot down by simple reasoning and facts. What exactly do you assume to gain by stating publicly I blocked you?? Sympathy?? Or just ridiculous self publicity. Just then, why are you even talking about the amount of bandwidth PS4 has when that isn't really relevant to CPU performance beyond a relatively modest amount? Top end x86 CPUs that are preposterously faster than PS4's CPU operate at that level well inside 25GB/s raw bandwidth!! Latency matters more....which is precisely what I said. This isn't the usual crap. It is unfortunate what I have to say often comes where I have to show that some of your points are in reality pointless, but thats how I operate on here. I don't deceive people or suffer fools gladly. I say it how it is, how it REALLY is. You should respect that instead of throwing your toys out the pram at me in public. All I stated was that the CPU is non native and you jump all over it defensively saying that is irrelevant, NO, it isn't, its just a fact! Then you go off on some massive tangent about raw memory bandwidth. Seriously, you might wanna rethink a lot of your comments carefully before you post them and try to stop yourself insulting other members.
Saying 7850 is midrange isnt arrogant or stupid, denying it is!!!! 7850 sits in the middle of the current AMD range. starting at the top- 7990, 7970 gigahertz, 7970, 7950 boost, 7950, 7870XT, 7870 gigahertz, then finally we get to 7850. Its 7 cards from the top and 8 from the bottom. You cant even buy the bottom 5 separately from a shop because they are OEM and only come fitted to pre built machines. Lets bear in mind that PS4 aint here yet until this current lineup is axed and replaced with faster parts! Windows 8 might have a recommended 2gb but it idles in much less if you need it to. Windows 8 uses what is there. If you have 8GB there, it can expand and use it to be faster. If it doesnt have all that then it folds itself down to less than 1GB most of the time. If you play a game on it you can shut everything down as you should if you game on Pc and it will be less than 1gb.
Stop trolling downandout PS4 is equivalent to a 2 year old PC http://www.extremetech.com/...
Yeah, nVidia is going to say good things about the PS4 hardware even though Sony ditched them, right? (._. )
"Stop trolling" You're one to talk, Mr. One Bubble.
One bubbles normally talk truth; fanboys debubble people who burst their bubbles. Nvidia are hardware masters; their words are pure fact. PS4 is pathetic hardware wise, better off getting a PC for graphics & BF4 1080P @ 60fps too.
Uh, No. My computer is 3 years old and smokes this thing... Although I still want one. It's looking like a solid console, but it won't replace my pc anytime soon, or ever, really.
What people are forgetting about is each dev can code knowing exactly what hardware the end user will have in a ps4. Yes, PC can outperform with obviously better specs but the catch is not every PC has the same number of cores, ram, etc. The devs have to code for a lowest common denominator and those with stronger hardware will get a boost in performance but its not the most efficient. Ps4 devs KNOW what amount of speed they can rely on and how much memory they can tap. This alone will make the coding much more efficient than a PC game. So its not fair to just say well PC has this processor and ps4 has this one so its worse. It might be smaller but it will be used more efficiently.
All rhe guys complaint the ps4 is a mid range PC should try to Build your high end PC under $1000.
I can build one that will outperform for under 600 bucks. COOLER MASTER Elite 430 RC-430-KWN1 39.99 MSI N650-MD1GD5/OC GeForce GTX 650 79.99 w/$75 in bonuses WD Blue WD2500AAKX 250GB SATA 6.0Gb/s 59.99 Diablotek PHD Series PHD450 450W 19.99 Silicon Power 8GB (2 x 4GB)DDR3 1600 56.99 BIOSTAR H61MLV2 LGA 1155 39.99 LG Black 12X Blu-ray Combo Drive SATA 49.99 Intel Core i5-3350P Ivy Bridge 3.1GHz (3.3GHz Turbo) 154.99 Windows 7 64 bit OEM 89.99 Total 591.91 and you can photoshop, web design, browser games, mmo's, office, and much more.....
nice try dude. I said high end meaning intel I7 pc under a grand. and ps4 got 8gb ddr5 not ddr3 foo. and then you can't play Sony great exclusive.
@shoddy Weak comeback, he pwned you pretty hard with a well constructed post.
i rebuke my statement . i don't care lol
It means... The PS4 is no George Foreman grill.
We have not seen it yet so that comment is a little premature.
I bet it would still cook better than the George Foreman Grill.
well in very simple terms: the PS4's on board CPU cache Memory Alone on the CPU/ has enough cache mem to through put instruction's on a per core basis that would choke the PS3, the xbox360 and the Wii. to put this in perspective there is 2MB of on board Cache per every 4 core's so that is 512 KB of Cache per core. Think about this the xbox360 had 1 MB of total on board cache to share with all three of its core's and the PS3 had 512 KB for the Main PPE while each SPE core had 256 KB of Local Store Memory! And We have seen what each one of those systems that the developer's can do to make great games on those platforms! the fact that there is 4MB of cache memory on board the PS4 is quite a bit. More than 2 times that of the PS3. Then take into account that unlike the PS3 that if the rumor is true about this being a 3D stacked System on a chip is true, than the 8GB of unified system+gpu ram will be stacked right on the same die as the CPU and GPU thus very fast system without more processing step cycles thus a very low latency for its instructions due to everything being right on the same die with a High speed wide bandwidth connection Bus the PS4 would be able to do quite well in game development for easy multi-thread management. there is still very little we know how its design is set up without a PCB board xray but chipworks will be ready soon enough to give out their finding's.
360 has 10MB of embedded RAM in the die to use as cache. Just needed to express that 1 point.
wii u has 32mb edram and 3mb on cpu 2mb for main core and a half for the other two so it wont be underpowered compared to sony's cpu
If Sony can pull off the looks and graphics they do currently with the much weaker ps3 I have high hopes for whats in store. I think some of the PC elitists are downplaying a system built specifically for games a bit too much... This is coming from someone with a gaming PC. I prefer the leisure playing on a console. Looking forward to what can be done on this system.
Extremely cheap common tools as opposed to specialized hardware and software this is not cheap? Dev kits work on win7 machines(commonplace in a software company these days) Integration of Visual studios 2010+ is great because many people learn these languages and toolsets formally quite a bit. In short opens PS4 game development to more groups.
I will tell you what it means... jack squat! Hardware isn't pushing software very much anymore and whatever Sony pushes out, it is the software that will define it. So wait to see what they do with the platform, rather than these artificially misleading specs that console manufacturers try to push on you. It's the end result that matter!
So, The ps4 DOES SUPPORT DX11(*Microsoft owned API propriety) & Native OPEN_GL 4.0. What the hell does the word "Beyond" fit in? Is it beyond dx11.1? And yeah? A head-set for every console, just like I suggested they should do in posts ways back. About the "reformed" DS4 controller, I assume the touch pad's 2 point control means your 2 thumbs can be used at the same time. And the pad's click function kinda tells me that the T-pad is a cross between a laptop touch-pad and PC-mouse's R/L click buttons, except it's 1 BIG mouse click button. And last,about this Very large HDD sony's touting. How many bids out there that this hdd is a Seagate Hybrid SSHD. starting at either 500gb or 750gb upto 1TB. Bets anyone? Nothing serious, just bragging rights. I'm calling it. http://www.seagate.com/file... http://www.youtube.com/v/7H...
console games arent nearly as optimized as people seem to think. They get a small boost and need less ram but lets not kid ourselves now. Not to mention pc games get optimzed over time, unlike console games that dont improve much after day 1. You can play almost any multiplat game on a 7800 at around console performance, because thats around console power. But why would you want to? https://www.youtube.com/wat... Dont let console makers fool you, the 7800 is getting better performance on pc than ps3 here.
All you have to know is its 8 to 10 times more powerful than the PS3. Have you heard about how hard it is to make PS3 games? Well, with PS4 its extremely easy. You're going to see games that have much better graphics and they will run at a stable framerate. You'll see more open-world games, less loading time and expanded online digital content.
hats off to sony
Damn 1T HDD lol Thats crazy lol how much this will cost $499 Cpu is looking crazy too
It's only a guess. They only said it will be very, very large
considering they offer 500gb drives for current PS3s, I'm thinking that 1 TB is not that big a stretch.
I have a 1TB drive in my PS3 now. Its not really that crazy if you have a ton of digital titles.
>Allows featured BEYOND DirectX 11 and OpenGL 4.0 inb4thissparksanotherdumbcons olevspcfanboywar lol get a load of shutUpAndTakeMyMoney and his typical console kiddy argument. BUBUBUBT SALES!!!
Hey there's an acronym for that "IBTSADCVPFW", much easier to use.
You're the one coming off like a kid, kid.
lol, that's what happens when ignorant console gamers talk about specs. They always go off topic to support their argument. "BUTBUTBUT EXCLUIVES!!!" "BUTBUTBUT GDDR5!!!!" "IT'S ALL ABOUT TEH GAMES, TEH GAMES!!11ONE!1"
Uh .... Its not a bout games ? Why tf would you buy a gameconsole ? To type a report ? Nothing matters but games , all this bs is just pissing in the wind
They are using Microsoft's Visual Studio to develop PS4 games?! I have to give Sony credit. While PS3 was all about ego, PS4 is all about practicality. The fact that they are utilizing tools from their sworn enemy demonstrates Sony's unprecedented humility. As a (non-game) programmer I must say, Visual Studio is a great development environment... or at least it was 4 years ago. Will someone let Microsoft know that color-blind design effects productivity!!
As opposed to what, visual studio is the only decent solution. I bet a load of programmers used it on the PS3 as well. What is your point? Plus don't you just love the caps lock menus.
Just because Sony and Microsoft compete in the same arena doesn't make them "sworn enemies". That is a view that the man-child mentality on this site has created... (the proverbial fight to the death). Sony is obviously trying to address the developer issues they had last time around. It has nothing to do about humility and everything to do with business.
Plus we learned that developers wont be going out of their way to cater to one console so best case is that all consoles have power to run great games
Infact after a little looking around. Sony distributes Vcproj files with the PS3 SDK. http://thatotherdev.com/201...
Visual Studio is still likely the best IDE available. And you can customize the colour scheme of just about every element to your liking, so I don't know what that last bit was about.
sony cares about me ill give them ma money
well they care about getting your money, but they're trying to get it the right way. By giving you better games and hardware than the competition and giving you more value through services like PS+
Exactly. Sony is a b
