7770 or 7790 is limited by two 64bit memory controllers and related L2 cache (64 byte per cycle per memory controller).
64 byte x 1050000000 Hz = 62 GB/s, hence 7770/7790 would have 124 GB/s i.e. 300 GB/s external memory would be pointless.

TFLOPS doesn't operate in isolation i.e. FLOP is supported by SRAM storage e.g. L1 cache.
The prototype-7850 with ~1.32 TFLOPS > 7770's 1.34 TFLOPS i.e. more L1 cache, wavefront buffer and LDS.

1.18 TFLOPS vs 1.76 TFLOPS = 55 percent more power is inconflict with

How much more powerful?
AY: It depends what youre doing. GPU, like 40 percent more powerful. DDR5 is basically 50 per cent more powerful than DDR3, but the memory write [performance] is bigger on Xbox One so it depends on what youre doing.
How is that going to translate to on-screen results for the kinds of games you want to make? So to optimise War Thunder on both consoles you could hypothetically make a better, prettier version on PS4?
AY: Yep.
KY: Probably yes. But again, thats not a very big deal.

Oh please dude STFU can you be a man an admit that 1.18TF is sh** not matter how much cache or bandwidth you have 1.18TF is sh** and lower than 1.84 TF,that is the fact is the reason why Ryse is 900p and not 1080p,is the reason Killer Instint is 720p :lol: Is the reason why Titanfall is not 1080p,Or dead rising 3,basically the only first party game i know is 1080p is Forza which is a damn racing game with everythig baked and faked,oh and you know racing games demand less to make them run at 60FPS 1080p.

The 7870 on Dirt on 2560x1600 ultra will get 74Â FPS,while those same setting on Metro will get you 20 FPS at best.
The whole Tflop don't work in isolation is sh** your theories are sh** and your arguments are been kill on the spot by xbox one games,let the game do the talking they are already talking 720p on a fighting game :lol:
Fine me a PS4 first party game that is 720p.
