AMD: PlayStation 4 supports hUMA, Xbox One does not

The old saying applies here.

"Don't bite the hand that feeds you."

But who are they going to feed instead? Nvidia? Nvidia didn't just bite MS, they ripped their arm off and caused my favorite game system from the PS2 era to die an early death.

Rockefellers. Skull and Bones. Microsoft. Al Qaeda. A Cabal of Bankers. The melting point of steel. What do these things have in common? Wake up sheeple, the landfill wasn't even REAL!

I have yet to see anything on XBO that touches that Killzone:SF footage released yesterday. I went from being pretty lukewarm on that game to ordering it Day One. That looked goddamned amazing.

Yeah, I'm already sold on Killzone. Game is going to look insane.

Alas no. But it won't be too long to wait.

Yeah sorry, I mean launch window since it comes out in February. Not a long wait though.

Remember what happened to Netscape?? I am not advocating anything like that. However they could see themselves being pushed aside from the PC space if MS decides to primarily cater to anything Intel wants.
What happened to Netscape is that Microsoft released IE, a superior product that people preferred. At the time, and for a short time after, IE was leaps and bounds the best browser on the market until Firefox began surpassing it. It sounds crazy to say that now, but it was true at the time.

And you think the PS4 won't have a GPU overhead?

the tiniest bit for pop up notifications maybe. Possibly around the same absolute amount as PS3, so relatively less compared to the overall power of PS4.

Simply put, the OS is never (IIRC) doing anything requiring GPU while a game is playing. If you bring up the XMB (or whatever its called now), then the game is paused and the OS can use all the GPU power.

On xbox they need to account for a situation where you might have the game snapped with an app running alongside - so the game can never have 100% (or has to deal with being throttled to 90%, not sure how it works). Even if you never use snap, it has to be factored in.

After scanning through the lastest screenshots, I kinda agree. X180 games seems to be a little more barren in objects onscreen and shader details...they have that flatter looks.

time heals wounds hehe. There's only room for 1 gpu maker in the dog house.

maybe Intel. They have been working on a graphics on chip solution for a while and have made some great progress.

So it was Sony/PS4 that, in fact, had the 'secret sauce'?!?!

How ironic given the PS4 vs Xbone technical talk leading up to today.

don't forget some of the underhanded stuff that happened with regards to how Windows managed "other" browsers.

In addition, the snapped application is run by the Windows-8-based host system while the game runs in the game partition. I am not sure if Hyper-V even supports dynamic GPU time allocation or if it would impact the performance of the game partition if it did.

I mean, it's pretty clear that the PS4 is going to be the superior console specs wise. If there's anyone Xbox fans should be mad it it's Microsoft themselves. They shat the bed now Microsoft has to lie(lay?) on it. I'm still getting both, I'm not planning on missing out on exclusives, but it's pretty clear Sony went out to build a games console first and foremost.

sounds good...now show it off with actual games that use the power.

Thats what I'm saying. All these indie games do nothing for me while XB1 has AAA titles across the board. This isn't the psone days when it could only push 150k polygons compared to N64 300K with texture shading and anti-aliasing. The visual difference in Real Games is going to be small.

A few people here are saying the CPU can't directly access the ESRAM though aren't they? Wouldn't that negate any potential advantage you're talking about?

It certainly would! I was sure I read, in a tech article, that the XB1 had this capability. I guess I'll have to double check, it's possible I got some other discussions(based on speculation) crossed with the more official stuff.

I would say though, I would find it really weird that MS and AMD overlooked this capability, especially with that large amount of SRAM sitting on-chip(literally right next to the CPU), and with the industry-wide focus GPGPU computing. The benefits of exploiting common CPU-GPU data via eSRAM is almost too obvious to overlook. I mean, how often have we seen a CPU and GPU in one integrated solution with a ton of SRAM on-chip?

For arguments sake, let's say XB1 does not have this ability. As weird as that maybe, what's even weirder? The Wii U does! That's a pretty powerful and useful capability for the underdog to have all to itself. Kinda ironic.

Yet, when it is all said and done, odds are there will be little-to-no difference graphically between Xbox One and PS4 games...

Pretty much.
 
It sounds like it could be quite significant for multi-platform titles.

I'm sure there will be objective differences but I don't know if they will be meaningful.

We see the relative difference pretty much daily on PCs. The performance differential between 'high' and 'very high' settings is often in the same region as the X1 and PS4 differential. I'm usually hard pushed to tell the difference, myself.

The difference could be as little as more subdivisions during tessellation or at a greater distance. Or higher resolution shadow maps or more accurate post effects. Things like that.

Case in point.

I figured it was best to go right to the expert, so I tweeted @ID_AA_Carmack
for an answer. I don't think he will tho. I don't know if all the twitter accounts in the world combine all their 144 allowable characters, if that would be enough space for a Carmackian explanation :)

Yup. Totally. Sony is totally outclassing MS in design, which is why I'm gonna be doing 90% of my gaming on PS4 and maybe get a One for exclusives. Maybe. I don't know if I still own any 360 exclusives, actually. I'm pretty disappointed in MS. I much preferred the 360's features, UI (minus the ads), web store, etc. I was their customer to lose this gen, and they did it.
 
That PS4 is more powerful then Xbox One. Nope. No one has confirmed that AMD has said that.




Nope. The AMD guy did not put down Xbox One.

We already know the PS4 is more powerful than the Xbox One. What's at play in this thread is a discussion on how big the difference is.

Really surprised that anyone at AMD would even comment on this right now considering they've partnered with both companies.

It's called Dat Revenge.

The only question is, which is your main console for multi-plat games.

Have you not seen Infamous? Killzone? This "AAA title" designation really needs to go away badly.
 
They are similar systems, it's just one is more powerful. It wont exactly cost extra to take advantage of those perks.

hUMA makes your life easier, so theres no reason not to use it.

its a low level implementation, not a tacked on feature - every single developer will be making use of it by default.


Oh damn! You know the future.


Sometimes you wanna go, where everybody knows your name, and you're always glad you came...

Lol. I'm sorry if I'm being a debby downer but it's like all current gen, we've spent all this time tech speaking and then all of a sudden we get mediocre stuff. I just would rather see than talk. Let's see the hUMA effects, not talk about the hUMA effects.
 
Double the framerate is not "niche of the nice". It's actually quite important. Shit framerates were a major weakpoint of the current generation. The supposedly game of the gen "The Last of Us" suffers from heavy framedrops.

You misunderstood what I said. "niche of the niche" means it's something only the most hardcore PC players ever bother doing. You need a very expensive PC to even attempt that stuff.

Well, we don't know if the article accurately represents what the AMD representative said or not, or if the article's author has mixed in his own interpretation. All I can say is that this site, which belongs to a big publisher of IT magazines, is as reputable as it gets in the space of mainstream German IT news. That does not make them infallible, of course.
 
These consoles use Jaguar CPUs and GCN GPUs. Jaguar + GCN APUs (Temash, Kabini, Kyoto) don't have hUMA.

HUMA is a feature that will debut on PC in 2014 (Kaveri). So, my guess is that Sony paid AMD to integrate this feature into PS4 while Microsoft didn't.

I think that Cerny said they worked with AMD to customize their HSA tech for the PS4. Thus, hUMA along with the Onion and Garlic buses were probably part of this customization.

There is no doubt in my mind that PS4 is more powerful then Xbox One. Let's get that out of the way.

I think your translation is a accurate one. I just think the way the article was written was misleading. Mixing the interviewer and interviewees responses in the article.

There is no way a professional from AMD would publicly put down a product they are manufacturing for a customer. They would get sacked.

AMD's Senior Product Marketing Manager Marc Diana says the Xbox One doesnt have hUMA? Can we confirm he is correct?

what people need to understand is that MS and Sony probably didnt know much what is AMD doing for other party, as per standard NDA signed by AMD... this is not taken lightly. Thats probably how Sony got inferior GPU last time around.

they basically built these APU's based on requirements from both parties.

And then we see games like Killzone, Infamous, and The Order and the differences feel much more tangible.

Just wait. I'm betting that by the time Evolution is done with Driveclub people will wonder why Forza can't have dynamic lighting too.

Why were you asking for a link, when it was in the OP? Now you are saying that the AMD guy could be lying or that this IT website mixed up what he said?

I think you are grasping at straws at this point. More likely than not what he said is true. I don't think there is "no way" that an AMD employee wouldn't comment on these things.

People are always talking. The article also talks of third parties on the floor talking about tangible differences in where their launch games are at.
