Video: 2100 Barrel Paintgun

From Wired’s Gadget Lab:

MythBusters Adam Savage and Jamie Hyneman were hired by Nvidia to demonstrate the speed differences between CPU and GPU processing. First, we see the pedestrian “CPU” in the form of a one-pixel-at-a-time paint gun. Painfully slowly, a smiley face trickles onto the canvas. Next, the “GPU”, represented by the truly awesome “2100 massively parallel barrel processors”, a huge paint gun with 2100 barrels spitting paint all at once. The results is a pixelized rendition of the Mona Lisa sprayed onto a wood-reinforced canvas. Total time elapsed? 275 ms. Watch to the very end to see the slow-mo version.
