Every one of the Xbox One dev kits actually has 14 CUs on the silicon. Two of those CUs are reserved for redundancy in manufacturing, but we could go and do the experiment - if we were actually at 14 CUs what kind of performance benefit would we get versus 12? And if we raised the GPU clock what sort of performance advantage would we get? And we actually saw on the launch titles - we looked at a lot of titles in a lot of depth - we found that going to 14 CUs wasn't as effective as the 6.6 per cent clock upgrade that we did."
I just destroyed Ronvalencia argument,like i claim many times the xbox one was a 7790 with 2CU disable for yields...:lol:
Total bullsh** so MS is telling people that 12 CU are better than 14 on GCN..:lol:
The same discussion with ESRAM as well - the 204GB/s number that was presented at Hot Chips is taking known limitations of the logic around the ESRAM into account. You can't sustain writes for absolutely every single cycle. The writes is known to insert a bubble [a dead cycle] occasionally... one out of every eight cycles is a bubble so that's how you get the combined 204GB/s as the raw peak that we can really achieve over the ESRAM. And then if you say what can you achieve out of an application - we've measured about 140-150GB/s for ESRAM
Yeah 140Gb/s 150GB/s not 204Gb/s it can't be sustained,so practical 140 to 150GB/s.
68GB/s + 140 = 208GB/s
68GB/s + 150 = 218GB/s
176GB/s + 40GB/s from CPU and Onion = 216GB/s
Also is ery funny how Digital Foundry is doing MS PR...:lol:
And is always leadbetter..
Goosen also believes that leaked Sony documents on VGLeaks bear out Microsoft's argument:
"Sony was actually agreeing with us. They said that their system was balanced for 14 CUs. They used that term: balance. Balance is so important in terms of your actual efficient design.
MS Architect riding in something that was prove to be false there never was 14+4...:lol:
We think we have very good balance, very good performance, we have a product which can handle things other than just raw ALU [GPU compute power].
This is pure bullsh** at its best MS trying to act as if the GCN inside the xbox was from Nvidia..:lol:
"On the SoC, there are many parallel engines - some of those are more like CPU cores or DSP cores. How we count to fifteen: [we have] eight inside the audio block, four move engines, one video encode, one video decode and one video compositor/resizer," says Nick Baker.
MS 15 different processors..
8 are Audio related.
4 Move engines.
1 video codec
1 video decode
and 1 video compositor resizer..
This keeps getting better and better so the 15 processors like it was predicted were sh** that are also inside the PS4 all but move engines which we know is to move data not to precess sh**..
MS counting even the batteries on the xbox one controller to claim better specs..:lol:
