Jon Peddie Research published its report about the GPU market in Q2 2011. The firm says GPU shipments were up 6.3 percent sequentially while PC sales grew just 2.4 percent, and that Intel made big gains in marketshare at the expense of both AMD and NVIDIA.
Between the first and second quarters, Intel purportedly enjoyed a 19.6% surge in shipments of graphics-enabled products, while AMD and Nvidia saw respective declines of 7.3% and 5.3%. Interestingly, JPR also says that Nvidia's slice of the discrete graphics market got 30% larger in the second quarter, reportedly because of design wins in many Sandy Bridge notebooks.
The research firm also sprinkles in a bit of news about the overall graphics market, saying shipments were up 6.3% sequentially amid slower 2.4% growth in the PC market at large last quarter. JPR notes that the higher-than-expected graphics growth raises "concerns about an inventory buildup" in the latter part of the year.
