Mercury Research just released desktop market share data for the last quarter.
According to Mercury Research, overall graphics shipments were up 3.8% from Q4 of 2008, which is attributed to improved desktop sales.
Overall, NVIDIA had a very slight overall market share gain of 0.3%, while AMD/ATI lost over 1% share.
In total discrete, standalone graphics (which includes desktop and mobile), NVIDIA made solid gains with an increase of nearly 3%, putting our total market share at 66%.
For desktop discrete only, the share gains were 5.4% over Q4, resulting in a market share of nearly 67%.
I got this from NVIDIA themselves, I imagine various websites will be reporting as well as these results just came out.
Not good news for the ailing AMD- losing 5 points of desktop marketshare with your strongest product lineup in 3 years doesn't bode well in these times of economic recession.
