ATI Mobility Radeon HD 5000 details leak

updated 03:30 pm EDT, Thu September 10, 2009

Mobility Radeon HD 5K to cover whole range

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.

The 5770, 5750 and 5730 will all be close parallels to the 5800 graphics chips, including shaders and memory, but won't support CrossFire. At least one of the GDDR5 models should have a 1.3GHz memory clock speed.

AMD's mainstream 5650 and 5600 don't have many details but should be more obviously feature-reduced compared to the higher-end video chipsets; the 5470, 5450 and 5430 will cater to the entry level and use a reduced 64-bit memory interface. They should respectively support GDDR3, regular DDR3 and DDR2 memory, with the speeds of each helping to dictate performance.

The finished products may not show until early 2010, or the season after the desktop cards are available.
