Digital Foundry has received new information pertaining the Xbox One’s form factor, power usage, and cooling systems from “insider sources.”
Microsoft’s fundamental principle, according to the site, is that the Xbox One should last ten years in an always-on state.
Another key aspect is the console’s larger size—a design choice meant to manage heat flow and help avoid overheating, a fault which plagued Xbox 360 with its now infamous Red Ring of Death.
“Microsoft has not released any official specifications on the dimensions of the final box, but extrapolating from the sizes of known components (principally the USB port),” Digital Foundry writes, “Xbox One is approximately 34x26x8cm – more set-top box than console, and noticeably larger than the launch version of the Xbox 360.”
Developers have reportedly told the site that in its idle state the console is “entirely silent,” with “fan noise only noticeable during gaming when the AMD processor is really being put through its paces.”
Xbox One’s quietness is attributed to hard drive installs—the fact that the disc drive isn’t used when playing games—as well as the large fan size, meaning it doesn’t have spin as much as a smaller fan.
“Also consider the technological make-up of the AMD processor. The closest match we have in terms of PC hardware to the Xbox One graphics core is the Radeon HD 7790, which draws 85W at peak,” the site said.
“The Xbox One version runs at lower frequencies and has two fewer compute units. AMD’s Jaguar CPU architecture is also highly energy efficient—it’s designed with tablets in mind. Even factoring in the DDR3, ESRAM and custom silicon, we should expect see a complete system power draw that’s a world away from the ‘power at all costs’ approach to the launch versions of the Xbox 360 and PS3, which used in the region of 170-200W.”
