MS aumenta la velocidad de reloj de la GPU de ONE....

New additions to the Xbox One hardware since it was last shown at E3 include a new graphics driver and an increase to the GPU's clock speed, says Whitten.

"Since E3, an example is that we've dropped in what we internally call our mono driver. It's our graphics driver that really is 100 percent optimised for the Xbox One hardware. You start with the base [DirectX] driver, and then you take out all parts that don't look like Xbox One and you add in everything that really optimises that experience. Almost all of our content partners have really picked it up now, and I think it's made a really nice improvement."

"This is the time where we've gone from the theory of how the hardware works--what do we think the yield is going to look like, what is the thermal envelope, how do things come together--to really having them in our hands. That's the time where you start tweaking the knobs. Either your theory was right dead on, or you were a little too conservative, or you were a little too aggressive. It's actually been really good news for us, and an example of that is we've tweaked up the clock speed on our GPU from 800mhz to 853mhz."

The Xbox One will have a custom AMD GPU that is supposedly comparable to the Radeon HD 7790 (according to Digital Foundry). The 7790 supports up to 2 GB of DDR5 RAM, can handle 4K resolutions, and has a graphics clock of 800 Mhz (shy of the 1 GHz that the 7700 boasts). According to a Gamespot Japan report (since removed, but cached via Google) Microsoft has upped the GPU speed by 53 MHz since E3. Additionally, the design team has rebuilt the graphics driver to optimize performance.
