AMD announced that according to the latest industry data, the company's ATI Mobility Radeon graphics chips account for half of the discrete graphics in notebooks today. The quoted figures indicate it has experienced a 36.5% gain in market share, and has sold 87.27% more units quarter-over-quarter during the first half of this year.

All in all AMD claims to have 53% of the discrete mobile graphics market share under their belt, making them the top dog. Featured in a wide variety of recent notebook launches, the company's Radeon HD 4000 series of GPUs is most responsible for the boost. Just to name a few, AMD's chips have made their way into the Acer Aspire 5739G, Alienware M17, HP Pavilion dV6T, Sony VAIO FW Series, and the Toshiba Satellite M500.

AMD GPU Division vice president Matt Skynner said that the latest market share data "validates the quality" of AMD's products. The company is looking forward to the back-to-school and holiday seasons as well as the launch of Windows 7.
