TechSpot has written a technology overview on S3's new Chrome S20 series GPUs.
Initially, the ChromeS20 series will consist of two cards, being released initially this week in China. Over the phone, Keith mentioned that releases for the U.S., Europe and Canada are set to occur soon, though he could not give a confirmed date. Whether this is from supply concerns or market concerns, he mentioned that we will probably see these products in the west during the month of November as well. The products are the ChromeS25 and the ChromeS27.
