AMD's line of discrete Mobility Radeon GPUs have taken the market share lead in the notebook market and are inside more than half of the notebooks being sold with discrete graphics today. Jon Peddie Research pegs AMDs discrete notebook share at 53% of the total market.

AMD made a huge gain over the previous quarter with 36.5% growth and 87.27% more units sold on a quarter-over-quarter basis for the first six months of 2009. AMD cites its Radeon HD 4530 and 4670 GPUs as the reason for the massive growth.

“As consumers increasingly demand greater visual computing capabilities in their notebooks, the market for discrete graphics is only expected to grow,” said Dr. Jon Peddie, founder and principal, Jon Peddie Research. “The increase in volume in the second quarter of this year, and in AMD’s mobile discrete market share, is a testament to consumers’ appetite for visual computing, and manufacturers’ readiness to satisfy it as we move into what has traditionally been the busiest season of the year.”
