Jon Peddie Research (JPR) has updated its PC graphics adapters shipments report for Q2 2011. After adjustments made to shipments of Intel Corp.'s integrated graphics adapters for desktop applications, it appears that the second quarter was not as good for graphics processing devices as initially thought.

After the adjustments made by the market research firm to its report, shipments of various - discrete and integrated - were flat with the second quarter of last year, or around 118 million units, which is a decline of around 10% from shipments in the first quarter. Such market performance is completely in line with usual seasonality as second quarter is typically slower than the first quarter when it comes to shipments of graphics adapters. The absence of massive increase of GPU shipments from Q1 to Q2 means that there was no heavy channel stuffing of inventory buildup, which means lower shipments in Q3 and Q4.

Manufacturers of graphics adapters usually adjust their shipments numbers they provide to independent analysts. Since the initial graphics adapters shipments report for Q2 2011 published earlier this month, JPR has reduced the sales figures for Intel's desktop integrated graphics by 17.6 million units. As a result, market shares of different vendors were also adjusted and it appears that they were statistically flat in Q2 2011 compared to Q1 2011.

“The revised Intel numbers paint a very different picture of the second quarter, and suggest that AMD graphics products continue to compete very well against the competition, and especially versus Intel’s Sandy Bridge graphics," said Jon Peddie, the head of Jon Peddie Research.

Despite of adjustment, Intel continues to lead the market with 54.9% share, Advanced Micro Devices is distant second with 24.4% and Nvidia Corp. is about five million graphics adapters behind AMD with 20.1% of the market. Nvidia’s share in the overall PC graphics market has dropped due to the company exiting the integrated graphics segment, but in discretes, Nvidia leads with 54.7% market share.

All leading suppliers of graphics adapters experienced shipments declines quarter over quarter, Intel boosted its shipments by 4% year-over-year, AMD remained flat and Nvidia's sales declined by 5.9% annually.

Please note that the news-story contains approximate numbers and does not contain the full picture of the market performance in the second quarter of this year. The full Q2 2011 graphics report is available for sale from Jon Peddie Research.
