Forums - Gaming Discussion - Ubisoft GDC Presentation of PS4 & X1 GPU & CPU Performance

ethomaz said:

Found that thread in GAF (http://www.neogaf.com/forum/showthread.php?t=915229) with a summary:

  • X1 Marginally faster CPU (due to higher clock speed, 1.6ghz vs 1.75ghz)
  • PS4 - Has actually significantly more GPU benchmarking than thought compared to Xbox1, nearly 100% more.
  • CPU + GPGPU management is essential and seems no where near optimal this early in the generation.

I just want to throw that in the face of everyone who said I was silly for saying the PS4's actually graphical performance is twice as powerful as the X1's.  No bias, just facts.

Even if the CPU is weak they can utilize GPGPU for PS4, because that's the purpose of GPGPU for the AMD technology right? PS4 also benefit from HSA technology and more CU on the GPU.


Correct.  The PS4's GPU actually has a ton more optimizations and add-ons to the the GPU that make it dominate at GPGPU.  That is why in the end the gap will grow even more than people think it will.

Thanks... I was trying to find the PDF link but couldn't find it.

Mods can lock if they wish... I will read the PDF now.

That has an even newer benchmark as well.

The CPU lead is unrealistic as it uses esram. For gaming no developer would use the precious Esram for the CPU, the GPU would suffer to much.



That PS3 Cell processor though O.o

We had this already. Nearly 100% faster PS4 GPU is when doing compute. In graphics bench (you don't have that pic here) it's 60-70% faster...pretty much what real world PC benchmarks of similar GPU's are showing.



Damn, the PS4's GPGPU capabilities destroy X1's. Talk about slaughtering. But its a little disappointing that in the benchmark, the both the X1 and PS3's CPU are performing betetr than the PS4's Sony, should seriously consider overclocking it to at 1.75ghz if not 1.8ghz (heck, if it can do more, better). It also would be nice if they overclocked their GPU to at least 850mhz also. And heck if your 2 disabled CU's can be reactivated, then do so.

If they were not using ESRAM for the CPU calculation, the Xbox One would also be right where the PS4 is.  Esram helps make faster calculations, that would normally be given to the GPU, as you'd have a huge performance loss without it.  Were talking 720p or under.

Not really a matter of what the CPU can do, it's what the cooling can handle.

I guess we have to wait for Naughty Dog to shows and smack every lazy developer face when Uncharted 4 comes :) .  I think when it comes to multyplatform games it's gonna be hard to shows PS4 graphic capability , because they trying to sell to all console fans, and parity clause is a nature thing for every third party developer. That's why console sales and sofware sales  is very important because the developer and publisher will see which console has a bigger fanbase and which fanbase buy most of their games, and determine which console will be  the priority.
