PS4 & AMD Kaveri APU both feature the Onion+ HSA memory Bus

AMD new Kaveri APU features the same Onion+ Bus found in the PlayStation 4.
So it's pretty safe to say PlayStation 4 APU is Heterogeneous System Architecture. (AMD, PlayStation, PS4)

It means memory bandwidth can be used far more efficiently than on current consoles / PC. Memory bandwidth is always on a premium when producing high end graphics.

What I want to know more is, what does Japanese Developer thinks about the Onion+ HSA memory Bus.

I was watching how this was going to be on next-gen PC hardware.
If the PS4 will have this, then it's even more incredible than b4.

I honestly tough it wasn't coming to consoles.

This is a little off topic but the true benefit of GDDR5 over DDR3 can be read on the discussion below. It's amazing that next gen hardware from both company's are supporting new top of the line hardware infrastructure.

Finally something!


Hey it does have GDDR5, and some. Ummm, nice implementation of HSA. Oh look, x86 designed cores. Very easy coding and porting.

But this is not the actual PS4 design I see. Must be beefier than the Kaveri.

"So it's pretty safe to say PlayStation 4 APU is Heterogeneous System Architecture."

I don't see why it wasn't safe since APUs are naturally HSA.

Didn't understand it either but the term "memory bus" sounds good..

To Helpful gamer: It means bandwidth is more plentiful & games will be easily to program (less read / write cycles). I imagine almost all developers (Japanese or not) well be very pleased about that.

Theoretically, this shows the lowest amount of computations per second.
These numbers are assuming 4GB's of unified memory. Although the bandwidth doesn't always increase with more memory, in this case, DDR5 can scale... and if you cut your comput times on cores in half, you can indeed add more ram and get better data transfer.
But for now, almost half of the memory is being used for background systems, so in essence this info means very little to us gamers.
All it really means for us is that games wont be downgraded because of memory being used by the operating system.
It means we get fast operating system, as well as games with no compromise.
It means great bandwidth for developers.
MasterCornholio  +   665d ago
"It means we get fast operating system"

Bingo which means a smoother user interface which i think many PlayStation owners will appreciate.

Because even though i enjoy the simplicity of the XMB, sometimes the UI gets horribly laggy especially when your in the middle of playing a game. But thats more due to the 256MB XDR of system ram than anything else.

P.S I know that the PS3 also has 256 MB of VRAM.
DeadManIV  +   664d ago
How is half the memory used for background stuff? How do you know this?
GutZ31  +   664d ago
(almost)Half the memory on PS4, being 3.5GBs is used by the operating system, the remaining 4.5GBs of DDR5 are completely used for gaming tasks.
So, as we already know, the PS4 has 8GBs of DDR5, therefor half of 8 would be 4... Do I need to make this any clearer? This is old news about the OS Being rather heavy on the memory.
GutZ31  +   664d ago
I stand corrected.
More than a third of the 8GBs of DDR5 memory is used by the operating system.
The remaining 5GBs of memory are used entirely for games.
The_Infected  +   664d ago
Why does it say 4GB unified memory when it's 8GB?
GTgamer  +   665d ago
PS4 has HSA i knew it.
MasterCornholio  +   665d ago
Yep that's why Sony signed up in the first place.

pyramidshead  +   664d ago
lol I remember the comment battles here way before the whole Hot Chips symposium event where people were trying their best to convince idiots that MS were a member but Sony wasn't. Good times. The dreams crushed after that date for certain users on here were delicious.

Everything is assumption until unproven on N4G. Its how the blogs work.
Cuzzo63  +   665d ago
Just google it. this stuff is really old tho. Nobody cares because its not flamebait. But instead how about we let Ubisoft confirm it also


Or if u want. We can have Mark Cerney explain why what and how.

Kayant  +   665d ago
Yh but it's a good one because the original leaked PS4 devkit with 4GB GDDR5 was using 2 steamroller cores and the first APU to use HSA will be Kaveri which uses GCN & steamroller cpu cores.

As this blogspot shows both are using Onion bus. So it's fair to think PS4 has HSA.

Am not that techy but anyone can see the similarities based on the leaked info which has been mostly true.

Edit - Also add what Cuzzo63 posted and it pretty much confirms it.

Saigon  +   664d ago
I am a little surprised at the disagrees I am getting because I was just asking a question. I wanted to know mainly because we have no technical evidence other than hearsay of the PS4 architecture. To be honest I do believe they have some type of HSA adaption, just not certain if it is direct HSA or something Sony configured themselves. Honestly we only have 40 something odd days before release and I am sure the gaming mags and online journalist will start receiving them in the next few weeks, so we should get some clarification.
Cuzzo63  +   664d ago
Well there are tech evidence as I jus posted links. From a well known dev and the creater himself. This stuff has been known since early March I think.
Kayant  +   664d ago
Sony is also part of the HSA foundation has a Contributor ---> http://hsafoundation.com/

The technical evidence we have is the leaked info which has been proven to be quite accurate as Mark Cenry and The devs porting the Crew like Cuzzo63 pointed out as they have made references to what can be found from the leaked info but yh we just don't know if it's Full HSA are partial. I would think it's full since the early devkits where probably kaveri based going by the leaked stuff and I wouldn't think they will give that up when they moved to Jaguar.

The PS4s true face is going to show with first party games. Trust them to deliver on all the tech fronts.

t3rrorc3ll  +   664d ago
Look. You guys are all morons. Xbox one is not more powerful than ps4.

Here's an example why. And is pretty much what mrxmedia does to all you hardcore Xbox fans (I am neither an Xbox or ps4 fan, I am a gaming fan). mrxmedia makes a blog post saying his insider told him this and that. So for example, my insider told me that ps4 outperforms 2 i7 3770k at 4ghz. It's all nonsense and no-one should be believing faceless comments. However devs have stated ps4 is more powerful than Xbox one. The games are showing with more native 1080p games on ps4. It is simple logic that Microsoft would not hide the facts if their console was more powerful, there is no need and it makes no sense from a marketing perspective. You always sell to your strongest point. So please every Xbox only fan remove your tin foil hats and stop listening to no name people like mrxmedia. He is simply setting you up for disappointment. And he may possibly be the greatest troll on the internet suckering you all in
devwan  +   664d ago
@t3rrorc3ll Maybe? I think it's clear he's having the time of his life stringing along those poor kids with his fantasy stories. I mean, he'd have to be seriously deranged, some kind of obscure medical condition, perhaps he's got multiple personalities living in his head who pop out to inform him of the latest and greatest insider info secrets?

It's much easier to believe he's just an incredibly effective troll riding the wave of his lifetime. I really hope that's the case, it's scary to think that there might be real people out there like him.

How about you guys stop giving MrXMedia attention? He knows he's lying, he just knows that him spreading false information gives him more attention. He knows what he's saying isn't true.

All covered by a convenient NDA, all was to be revealed to the world on 30th Sep.

Said NDA got conveniently extended by 3 months to December lol

Which consequently doesn't make sense as when people get the XB1 at launch some of them will be tearing it to pieces to break it down for the consumers as to what's inside for youtube, tech websites and enthusiast forums. I don't really see how they're going to hide anything or keep anything quiet after launch.

Which leads any logical person to believe that the NDA doesn't even exist unless they delay launching the XB1 until 2014, which doesn't seem likely.

Lol fanboys to either console is killing me , it's only a game console and this brand loyalty and fanboyism is hilarious. Neither Sony nor Microsoft cares about you they just wanna make money !!
SniperControl  +   664d ago
Well of course they do, that is business, but i would rather spend my hard earned money with a company like Sony who offer a better buying experience, a better, warmer customer service experience.

I work in IT and have to deal MS support on a daily basis, they are just cold & clinical to deal with.
wiz7191  +   664d ago
Every time I had to call Microsoft customer support I had good experiences idk maybe they just don't like you or something who knows
SniperControl  +   664d ago

I do have some history with them, my 360 went faulty with-in 6 months of me buying it, short story is they could not repair it, so the tw@t5 at the service centre tried to fob me off with a refurbished 360 instead of a new one which by law I am entitled to under the warranty.
Currenty Trading Standards in the UK are dealing with it.
By the way, this is my 3rd 360.

However on my work side of things, I am totally professional and do not let my personal grievances get in the way, I am just sick & tired of dealing with lackys in an call centre somewhere in india who do not give a 5h1t about anything because MS are paying them a pittance. All they want to do is deal with you as quickly as possible to get you off the line.
nunley33  +   664d ago
@wiz since he deals with them as a professional it person, his experience would be a bit different. but he cite his times as customer also. a company like ms would naturally be nicer to customers on the line than the it guys.
wiz7191  +   664d ago
You must don't take care of your console I've only owned two 360 since launch , my launch one rrod two years ago I bought another and haven't had any problems ..
SniperControl  +   663d ago

I dont take care of my consoles?? what?

My 1st 360 RROD after 2 years, My 2nd 360, just stopped working at all(apparently my mobo) went after 6 months which MS could not repair, so they tried to rip me off by replacing it with a refurbished unit, my 3rd 360 i won in a raffle and sold it 2 weeks later(of which the funds will go towards the PS4)

I still have and use my original launch PS3 60gb, no problems what so ever, my PC that i built 2 years ago is still going strong to this day, my 2 PSP's are working perfectly.

In fact my Atari 2600 still works to this day, iam sure if i booted up my Spectrum 128k and my Amiga A600, my SNES, my Masterdrive, my launch Dreamcast, my launch PS1 and my launch PS2 they will all be working perfectly.

So dont lecture me about taking care of my stuff!
johndoe11211  +   664d ago
I got news for you, your favorite sports teams and athletes dont give a rats a$$ about you either, they just want you to pay money to see them play so they can make millions. That doesn't stop you from being passionate about sports though does it?

wiz7191  +   664d ago
No not really but I don't pay to go see them .. but seriously though the fanboy creep is ridiculous Sony and Microsoft both have issues , I had bad experiences with Sony and Microsoft. In my eyes they both are good consoles what's the point of bashing either one
