Quarter-to-quarter, the market declined 5.4%, JPR estimates. The findings were disappointing year-to-year, declining 5.2%. AIB shipments were down even though PC shipments were up in the quarter.
The overall PC desktop market declined 3.7% quarter-to-quarter including double-attach-the adding of a second (or third) AIB to a system with integrated processor graphics-and to a lesser extent, dual AIBs in performance desktop machines using either AMD's Crossfire or Nvidia's SLI technology.
On a year-to-year basis we found that total AIB shipments during Q2'13 dropped 5.2%, less than the overall desktop graphics decline of 9.3% or the total PC graphics decline of 12.8% overall. GPUs are traditionally a leading indicator of the market because a GPU goes into every system before it is shipped; most of the PC vendors are guiding down to flat for Q3'13.
JPR found that AIB shipments during 2013 2Q behaved according to past years with regard to seasonality, but the drop was less than the 10-year average. AIB shipments decreased 5.4% from the last quarter (the 10-year average is -8.9%).

- AMD's quarter-to-quarter total desktop AIB unit shipments increased 0.8%.
- Nvidia'squarter-to-quarter unit shipments decreased 8.9%.
- Nvidia continues to hold a dominant market share position at 62%.
- Figures for the other suppliers were flat to slightly declining.
The AIB market now has just four chip (GPU) suppliers, who also build and sell AIBs. The primary suppliers of GPUs are AMD and Nvidia. There are 52 AIB suppliers, the AIB OEM customers of the GPU suppliers, which they call "partners."
