Carmack: It's 'almost amazing' how close the PS4, Xbox One are

Much ink has been spilled about the Xbox One, the PlayStation 4, and the hardware they each have under the hood. Their configurations may be a little different—the PS4 has single pool of GDDR5 RAM, for instance, while the Xbone is rumored to split its memory between eDRAM and DDR3—but the silicon and official specs are pretty close.

id Software's John Carmack seems to agree. According to Polygon, the id co-founder and programming guru spoke about the new consoles at QuakeCon yesterday. While he admitted to not having benchmarked them yet, he went on to say the following:

"It's almost amazing how close they are in capabilities, how common they are," Carmack said. "The capabilities they give are essentially the same."

Carmack added that he was more comfortable with development on the Xbox 360 than on the PlayStation 3 this cycle, but Sony has made "large strides" toward making things better for developers, and he's optimistic about PS4 development. There's just one aspect of the new consoles he seemed unenthusiastic about: Kinect. Carmack said Microsoft's motion-sensing controller is "sort of like a zero button mouse with a lot of latency on it."

In related news, Gizmodo reports that Microsoft has increased the clock speed of the Xbox One's integrated GPU from 800MHz to 853MHz—a "nice little bump," as the site points out. The company has also cranked out a new driver that "really optimizes that experience," and which apparently almost all of its development partners have already adopted.
