XAA, or the XFree86 Acceleration Architecture, is over twelve years old and finally in 2005 it was greeted by a replacement, EXA. XAA is nearing an end-of-life and Intel is prepared to remove XAA acceleration within their next Intel graphics driver release later this year. EXA was designed to offer speed improvements over XAA by accelerating more options and enhancing X's RENDER extension. Depending upon the driver, it wasn't until recently though that EXA really did have some modest speed advantages. A new acceleration architecture has now joined the mix. Intel's Keith Packard has announced UXA, which is short for the UMA Acceleration Architecture.
