It looks like GPU shipments for Q4 2012 didn't do so well according to Jon Peddie Research's latest numbers - where they dropped 8.2% sequentially and 11.5% year-over-year. The drop in GPU shipments is being blamed on the popularity of tablets, as well as the continuing and damaging recession.

This has caused JPR to revise their compound annual growth rate (CAGR) for PC graphics from 2012 to 2016 to 3.2%, with the total shipments of GPUs in 2016 hovering at around 549 million units. Intel's shipments dropped just 2.9%, but AMD dropped by a much larger 13.6% and NVIDIA were worse, dropping by 16.7%. Market share wise, we saw Intel hold onto 63.4%, which was a gain of 3.4%, but this was at the expense of AMD and NVIDIA which dropped 1.2% and 1.73% respectively - down to 19.7% and 16.9%.

There are some breakdowns from JPR's latest report below:

• AMD's quarter-to-quarter total shipments of desktop APUs increased 0.8% from Q3 and declined 19.1% in notebooks. The company's overall PC graphics shipments slipped 13.6%.
• Intel's quarter-to-quarter desktop processor-graphics EPG shipments increased from last quarter by 3%, and Notebooks fell by 6.76%. The company's overall PC graphics shipments dropped 2.9%.
• Nvidia's quarter-to-quarter desktop discrete shipments fell 15.1% from last quarter; and, the company's mobile discrete shipments dropped 18.4%. The company's overall PC graphics shipments declined 16.7%.
• Year to year this quarter AMD shipments declined 29.4%, Intel dropped 5%, Nvidia slipped 4.6%, and VIA fell 10% from last year.
• Total discrete GPUs (desktop and notebook) fell 15.9% from the last quarter and were down 9.7% from last year for the same quarter due to the same problems plaguing the overall PC industry.
