i can see ps4 handle games later on this gen much better than x1, time will wide the gap even more as this shows..

It's because the r9 290x (and obviously the X2) is the only other GPU on the market that has the amt of ACE's as the PS4's modified APU, and since they were running a benchmark on GPGPU compute, you'd need another card w/ similar features.  Otherwise yeah, the 290x is way way more horsepower, altogether.

PS4 needs to totally dominate for that, then the developper wont care about making big inferior versions and get less sales on One

Yep, it's interesting too see real Benchmark results, even though I was expecting these numbers.

PS4 in the hands of great developers will make miracles.

Why is everyone surprised?


Microsoft's Engineers On Xbox One: "We Purposefully Did Not Target The Highest End Graphics."
"We targeted it more as a broad entertainment player."


From a rather massive article on Engadget, showcasing the making of Microsoft’s newly announced Xbox One, comes a most interesting snippet – that Microsoft purposefully didn’t target the “highest end graphics” when building the console.

It’s in the video, so you’ll have to sit through a 20 second Windows 8 advert before you can skip to the bit (about 5:40), but it’s there. “We purposefully did not target the highest end graphics. We targeted it more as a broad entertainment player.”

Picked up by GAF, it’s a strange claim to make in a promotional piece, and whilst that way of thinking worked for Nintendo with the original Wii, up against the way Sony are marketing the PS4 as a real powerhouse it’s a baffling quote.

Note that nobody’s claiming that the PS4 is technically better, just the choice of words.

No doubt the console is capable of great things – visually too – but from what we’ve seen today (and echoed around the internet) perhaps Microsoft’s new console is going to have to flex its muscles a little harder than some thought before the conference kicked off.

We’ll know come E3, when we’ll get chance to test the games first hand.

Aerys said: So the gap is not closing but growing Cerny is a genius

The Gap will grow in those games where 3rd party developers will put the effort.  If Devs push both PS4 and X1, the Gap will grow.

if the devs don't care at all or get incentive to make parity or very close version, you will get that. It's up to Developers.

  Sure people like Naughty Dog will blow us away ;)

All these benchmarks... So the slides actually "confirm" that the CPU in Xbox One is actually a little bit faster than the one in PS4 but another benchmark shows otherwise (the compression benchmark, that is).
Even more the PS3 CPU is more capable than PS4s?
Furthermore they say there approach is bandwidth limited which automatically favors PS4 because of its way better ram - but by this they also only mention what they did to optimize for PS4 and not what they did to optimize it (if at all) on Xbox One and not mentioning usage of ESRAM for one time.

Actually, they have the same CPU, it's just the One one is overlocked, so sony could do the same for the PS4 but it seems overlocking the CPU have consequences for a console

The GPGPU is the best way of optimizing the performances by a lot, that's why Cerny bet everything on this and why this document focus on that to get better performances

Benchmarks say the truth.  When they showed X1 CPU slighty better, they clearly said X1 CPU was using ESRAM, which was just theory and in real Game application is the GPU which makes the most use of ESRAM. 

Also, don't make the most common mistake that some do : don't compare CPU vs CPU, or GPU vs GPU alone. You have to look at the whole Achitecture of each Console.   Let's take an example : PS3 vs 360. In that Benchmark, PS3 CPU shows much better performance  than the 360 CPU(roughly 3 times), but it's not the whole story.  The Cell in the PS3 has to do so many heavy stuff to support the RSX in graphical computing that in the end the left power for Generic task is not superior at all VS 360 CPU.  On the other hand, the 360 CPU is almost free to do all the Generic task cause the 360 GPU is more powerful and sofisticated and does not need help from the CPU.

And you say ''Even more the PS3 CPU is more capable than PS4s'';  completely wrong.

As I explained above, most of PS3 CPU resources are 'wasted' for graphical stuff, while the PS4 CPU can be supported by CUs GPU to massively improve CPU performance in Physics, collision system, AI, animations, generic task, etc.

Compare APU vs APU, compare Architecture vs Architecture, don't ever compare 1single element VS 1single element.

This explains in few words how the Asynchronous Compute Engine works.  Devs need some more time to take full advantage of it.

The Asynchronous Compute Engine basically tells data were to go, queuing up the commands and then processing them when the GPU has the spare “Cycles” to process it.

Imagine yourself driving on a highway, with hundreds of lines – but ahead of you is a toll booth. Consider that you can’t see which booths are free from your perspective (you’re stuck behind large trucks and so on after all). So you’re effectively only able to use signs tell you which lane to take. The more ACE’s there are (in this case, electronic signs) to tell you which lane to go to, the faster you’ll be sent to a lane that’s tollbooth is as empty (or at least as free) as possible.

So in other words, the ACE will accept work, and then dispatch it to a CU (compute unit) for processing when its resources are freed up. The task of the ACE is to figure out the priority of the task – in other words, to ensure that if it processes a bit of compute data, it won’t negatively affect the frame rate of the title.

Just to put this into some perspective, the PlayStation 4 has 1152 of these lanes (Streaming Processors), with 64 ‘signs’ telling the cars where to go. As a comparison, the Xbox One has 768 ‘lanes’ (Streaming Processors), with 16 ‘signs’ to tell the traffic which way to flow.

Problem is that GPGPU "steals" power from your GPU to do rendering tasks so this always comes with a trade-off. We have to see how much it can help in the future.
