Microsoft: Xbone Is 3x As Powerful Than X360 (Phil Spencer Twitter: It Was A Mistake)

I don't think I said there was "barely any improvement", I said the GFLOPS is 9x as much, but the speed gain isn't as much.

As you can see, the Core clock rate is only a 3x improvement in the PS4. In comparision to the 9x improvement inGFLOPS, a 3x improvment in Clock Speed isn't much. I don;t understand why 2-3 people quoted me and laughed, do I have my facts wrong?

.....

Like I showed above, it's only a 3x improvement. Still big, but not crazy compared to the FLOPS increase of 9x.

I think it's the way I say things, people get offended. PS4 is obviously a pretty powerful system, I'm just saying it's not a huge jump, just big. From PS2 -> PS3 it was like a 25x in performance, now from PS3 ->PS4 it's about 9x, and the Clock Speed is only 3x of a jump. 3x < 9x < 25x, lol.

@bold Oh boy, you really don't know much about hardware, do you?

BTW, RSX is gimped 7800GTX with memory bandwidth of 7600GT, and its core clock is 550MHz. PS4's GPU runs at 800MHz - I'm just hoping you won't make any additional conclusions based on core clocks. ;)

Jump from 6th to 7th gen, contrary to what most people are led to believe, is around 10x, pretty much the same as objective jump from 7th to 8th gen - actually, Mark Rein from Epic Games stated this on PS4's reveal in February (Mark Cerny confirmed "at least 10x" in Fallon's show). Problem is, subjective jump is not as big, due to length of current gen - for it to be same as subjective jump in previous gen it should've been somewhere around 16x, which would call for 7950 Boost to 7970 level GPU...which is completely unreasonable, due to gfx cards not progressing in last few years as fast as they used to.
