Intel - It Was One Heck Of A Year For Sandy Bridge Graphics

The year began with Intel launching their "Sandy Bridge" processors. While the CPU performance was very impressive for these latest-generation Intel processors, the graphics performance under Linux was a problem. The drivers were not ready in time. Well, they actually were technically available, but in Git source form and not easy for Linux desktop customers. There were also some initial hurdles in the Sandy Bridge Linux graphics support. However, over the past year, the Intel OSTC developers working on the open-source graphics support have dramatically improved the situation. As this article recaps the performance over the past year, Sandy Bridge is now rocking under Linux and Ivy Bridge is ready to go.
