"That's right, 189 million discrete GeForce GPUs, a number Nvidia only recently elected to disclose, perhaps because it makes for stimulating counterpoint in media conversations dominated by console-speak. Put that in perspective: Sony's PlayStation 2 topped 120 million worldwide in 2007 (according to Sony). Nvidia's number tabulates consumers with GeForce 5, 6, 7, and 8 series GPUs for desktops and notebooks. That's counting only a small number of motherboard GPUs, and none of Nvidia's contract deals making specialty chips for anyone else (including console manufacturers.)"
"The information was recently disclosed in an interview with Nvidia's Roy Taylor, Vice President of Content Relations, and James Wang who works in the company's technical marketing group. This is the second part of that interview."
