A Chinese leak today has slipped many core details of AMD's next ATI notebook graphics platform. The Mobility Radeon HD 5000 series is expected to be a direct translation of the desktop models and should have similar lines. At the top, the 5870, 5850 and 5830 will all have a very large 1,600 shader units (effects processors) and should support CrossFire on gaming-oriented desktop replacements. The top two will support fast GDDR5 memory while the 5830 will need GDDR3.
