Today ATI is rolling out the ATI Mobility Radeon X1800 and X1800XT GPUs for mobile users which follows the release of the X1600 mobile part in December (which we previewed here). The X1800 has 12 pixel shader pipelines and 8 vertex shaders, and the X1800XT has 16 pipelines and 8 shaders. In contrast the X1600 mobile has 12 pipelines and only 5 shaders.
The Mobility Radeon X1800 parts are clocked slightly slower than their desktop cousins. Coming in at 550MHz on the XT model, and 450MHz on the vanilla 1800, it’s a little slower than the 625MHz we see on the X1800 XT desktop card. However, the slower clock speeds will help with power conservation while providing enough performance for games and 3D applications.
“ATI’s Mobility™ RadeonÂ® X1800 is one of the world’s most powerful mobile graphics technologies for gaming enthusiasts and performance notebook PCs, combining top 3D graphics performance, high quality video playback, and exceptional image quality. A 90-nanometer process GPU adds visual velocity to a new hyper-efficient 3D architecture featuring ultra-threaded operation, high bandwidth GDDR3 RAM, and a new ring-bus memory controller.
