JPR estimates that approximately 55.6 million desktop graphics devices shipped in Q1 2006, 34.6 million or 62.2% of which were integrated parts. The desktop graphics segment saw shipments fall 7.5% from Q4 2005 to Q1 2006 but shipments grew 22.3% year-over-year. Integrated desktop shipments dropped 8.6% sequentially but increased 33.7% annually. Discrete desktop shipments fell 5.7% on a quarterly basis and grew 7.2% year-over-year, according to JPR.
Overall, Intel claimed 34.1% of the desktop graphics market, ATI held 26.1%, and Nvidia followed with 23.3% market share. In the discrete desktop segment, however, Nvidia grew segment share from 51.5% in Q4 2005 to 53% in Q1 2006. ATI saw its discrete desktop share decline from 46.3% in Q4 2005 to 45.1% in Q1 2006.
Desktop discrete graphics processors is the primary business for both ATI and Nvidia, which means that declines in the segment are alarming for Markham, Ontario-based ATI. Another positive news for Nvidia Corp., a bad news for its rival, is that according to Mercury Research, Nvidia grew share in the performance DirectX 9.0-class and combined DirectX 9.0 desktop GPU segments from 79% to 83% and from 57% to 60%, respectively, from the fourth quarter of calendar 2005 to the first quarter of calendar 2006.
“ATI's desktop and notebook IGC shipments are growing steadily and providing a challenge to Intel in these segments. But Nvidia is in turn challenging ATI for more lucrative discrete graphics share. Nvidia leads ATI in the discrete desktop segment and grew share in the discrete mobile segment by nearly five points in the first quarter,” said Lisa Epstein, a senior analyst at Jon Peddie Research.  |
