According to the latest market share data from Jon Peddie Research, folks in AMD’s graphics division have a good reason to pop open the champers over the weekend.

AMD ended Q4 2011 with a 24.8 percent market share, growing 7.8 percent sequentially over Q3. On the other hand, Nvidia’s share dipped by 3.1 percent, from 16.1 percent to 15.7 sequentially. Intel’s growth also came to a halt. Chipzilla dropped from 60.4 to 59.1 percent.

Looking at the year-on-year figures, the result is even better for AMD. In Q4 of 2010 AMD commanded a 24.2 percent share, while Nvidia was in a close second with 22.5 percent. Now AMD is in a comfortable lead, shipping 58 percent more GPUs than Nvidia. Nvidia also lost share to Intel, as Intel had an overall share of 52.5 percent in Q4 10, and now it is at 59.1 percent.
