The unrivaled Jon Peddie, the eponymous research company specialized in financial information, has just published a sample of some of its estimations for graphic market shares for the first quarter. All figures given concern the number of units sold. Given that a GMA 945GM is equivalent to an RV670, we shouldn’t take these numbers too seriously even if they do often represent general market trends. The fifth column shows the difference in the number of units delivered compared to the same quarter a year ago (in parentheses this means a reduction).

The first conclusion is that Nvidia and Intel to an even greater extent are doing very well. ATI compensates for a 5% reduction in market shares with the fact that unit sales still grew. This figure can explained by an increase that was lower than the overall average market growth. As for SiS, Matrox and VIA , they continued to slide due to a lack of real innovation in this quarter as S3’s Chrome wasn’t available before April. It will be interesting to observe in the coming months if they manage, as little as it may be, to impact the current trend. Intel’s GMAs are found in 46% of PC desktops, Nvidia’s GeForces in 31%, and ATI’s Radeons in only 17%. The sequential increase in this segment was 8.5%.

On the laptop IGP/GPU market, Intel continued its determined progression which seems to be essentially to Nvidia’s expense as AMD manages to hold its position here. Note that for the quarter notebooks represented 32.6 million units, 31.2% of the market, or 5% less than the previous period.
Finally, we can see that the market showed a sequential increase of 4% in the first three months of the year which normally are more subdued than the fourth quarter.
