Accurate Math in Processors may not be important

At least not for certain tasks, such as rendering video, even of 3D environments.

An interesting bit over at Kotaku.

"The difference between the low-precision and the standard arithmetic was trivial," Shaw says. "It was about 14 pixels out of a million, averaged over many, many frames of video." "No human could see any of that," Bates adds.

Why is this a big thing? Because apparently, you can fit 1000 low precision cores in the space where 12 normal cores would go.
