Oh no this wouldn't make that big of a difference.

 

8% of the XBONE GPU is 105 gigaflops. The current difference between the PS4 and XBONE GPU is roughly 530 gigaflops. With this rumored change the difference would drop to 425 gigaflops. That's not that big of a difference. Let's equate it to resolutions.

 

If a PS4 game is 1080p and an XBONE game is 720p, this change would only bring the XBONE up to 748p-752p. Now that's what the math shows instead of how things really work, but it does help demonstrate how small of a bump this would be in the grand scheme of things. It's not making it within one stage of the PS4 instead of two.

Like you said, I don't think direct math like that applies when it comes to graphics. I was basing my assumption on PC graphics card benchmarks that I was looking at with GPU's that are close to the power of the Xbox One's GPU, an 8% overclock seems to get you a one stage boost in either fps or resolution depending on the exact settings and game. Tomb Raider on Xbox One is already within one stage of the PS4 if the rumors are true, 30-45 fps on Xbox One, 45-60 fps on PS4, with the same resolution, textures, AA, effects, etc. on both supposedly. And looking at Tomb Raider PC benchmarks, that extra 8% would give the Xbox One an extra 5 fps, bringing it up to 35-50 fps, only 10 fps behind the PS4 version. I'm of course assuming that Tomb Raider is indicative of future multiplat games on the Xbox One and PS4, which might not be the case.

Nah, a lot of incorrect assumptions.

First of all the boost from 90% to 98% is not the same as an 8% clock speed increase.
Secondly it's not 30-45 vs 45-60 The PS4 version will be at ~60 FPS (should mostly be in the 55-60 range though) and the Xbox One version will be at ~30 FPS (30-35 FPS ideally) and in empty environments the FPS can go as high as 45.
Thirdly you can't say an extra 8% will bring 5fps on xbox one, when you claim a 55% difference ammounts to a much smaller gap.

If it's average 35 vs 55, the extra available gpu time should bring it to 38 vs 55.
