ATI has managed to keep its position as the largest supplier of graphics for notebooks, but its market share is falling
. ATI saw its share drop from 49.9% to 42.9%, compared to the third quarter, according to a report from John Peddie Research. The report claims that ATI's notebook market share was because Intel shipped plenty of integrated chipsets, while Nvidia sold more discrete notebook graphics products.
In contrast, NVIDIA has seen its shipments grow by over 25% during quarter four of last year, giving it an overall 25.7% segment share.
