[QUOTE="btk2k2"][QUOTE="ronvalencia"] His misapplying 7770 on X1.ronvalencia
It is close enough really. We know of too many differences between the X1 and the PS4 that we cannot replicate with a GCN card that actually exists so any numbers you get are going to be rough. Let's just generalise though. We know that the with the shader and fillrate performance differences between the X1 and the PS4 we can expect 35-45% advantage for the PS4. That will then be further modified based on the things we cannot pin down such as the effective X1 memory bandwidth or the extra ACE units in the PS4. If we go on that sort of difference we can draw some general conclusions about how multiplats will look and perform on each platform and in the end it is pretty safe to say that they will be prettier and/or smoother on the PS4. It will vary from dev to dev as to where on the prettier --> smoother scale it lands but with the exception of games that do not stress the X1 they will fall somewhere on that line.DF has attempt to match the console's shader power via 600Mhz 7870 XT and 7850. DF has negated the triangle rate difference between the two boxes.
7770's 1.28 TFLOPS was based on 10 CUs @ 1Ghz which doesn't match X1's 12 CU@ 853Mhz anyway.
From www.tomshardware.com/reviews/768-shader-pitcairn-review,3196-5.html
12 CU @ 860Mhz 7850/7830 prototype is the closest to X1's 12 CU @ 853Mhz. i.e. matches in register file, L1 cache, local data storage, TMUs/load store, scalar cache, branch units and 'etc'.

My posts are framed with the following dev quotes.

Speaking to VideoGamer.com at E3, Ilvessuo said: " Obviously we have been developing this game for a while and you can see the comparisons. I would say if you know how to use the platform they are both very powerful. I don't see a benefit over the other with any of the consoles."

"The difference is small, and I don't really need to worry about it," he said, suggesting versions for Xbox One and PS4 won't be dramatically different.

"Of course, the Xbox One isnt to be counted out. We asked Guay how the Xbox One version of Watch_Dogs would be different compared to the PC and PS4 versions of the game, to which he replied that, The Xbox One is a powerful platform, as of now we do not foresee a major difference in on screen result between the PS4 and the Xbox One. Obviously since we are still working on pushing the game on these new consoles, we are still doing R&D."

"We're still very much in the R&D period, that's what I call it, because the hardware is still new," Guay answered. "It's obvious to us that its going to take a little while before we can get to the full power of those machines and harness everything. But, even now we realise that both of them have comparable power, and for us thats good, but everyday it changes almost. Were pushing it and were going to continue doing that until [Watch Dogs] ship date."

"Other information has also come to light offering up a further Orbis advantage: the Sony hardware has a surprisingly large 32 ROPs (Render Output units) up against 16 on Durango. ROPs translate pixel and texel values into the final image sent to the display: on a very rough level, the more ROPs you have, the higher the resolution you can address (hardware anti-aliasing capability is also tied into the ROPs).16 ROPs is sufficient to maintain 1080p, 32 comes across as overkill, but it could be useful for addressing stereoscopic 1080p for instance, or even 4K. However, our sources suggest that Orbis is designed principally for displays with a maximum 1080p resolution."

Carmack on next-gen console hardware: 'very close,' 'very good'
THANK YOU!!!!
I am so sick of Sony fanboys (and I am talking directly at Tormentos right now) talking out of their arses about how "better" PS4 games are going to be than XB1 games because they look at some raw statistics and all of a sudden are expert game developers.
I re-iterate what the real experts say, and cows debate me as arm-chair game developers. :roll:
