ATI Mobility Radeon HD 4850

The ATI Mobilty Radeon HD 4850 from AMD is a DirectX 10.1 high end notebook graphics adapter. Technically it is based on the desktop HD 4850 GPUs but with a lower clock rate to save energy.

The gaming performance of the ATI Mobility Radeon HD4850 should be compareable to the desktop HD 4830 and therefore very good. The high amount of shaders and the 256 bit bus allows to run every DirectX 9 game in high resolutions and details. Demanding DirectX 10 games, like Crysis can be played with medium to high details.

The Mobility HD 4850 is based on the RV770 chip and features 800 stream processors (160 5-dimensional shader cores). These cores do the graphic work of the shader- and pixel pipelines of older GPUs. The stream processors are also called ALUs and are grouped in five-way VLIW units. Each of the five instructions of a VLIW bundle has to be independent from the others and therefore the performance depends on the optimization of the driver.

The Mobility Radeon HD 4850 includes the Avivo HD called video technology including an onboard soundchip for 7.1 sound output over HDMI or DisplayPort and the 2nd generation UVD (Unified Video Decoder). This UVD 2 supports full bitstream decoding of H.264/MPEG-4 AVC and VC-1 streams. In addition to this, it also supports dual video stream decoding and Picture-in Picture mode which makes the UVD full BD-Live compliant. Simplified, the Avivo HD technology handles all video tasks and enables the GPU to decode HD videos.

AMD published a current consumtion of about 45-65 Watt for the HD 4850-4870. Still it is unclear if this value represents the chip alone or the whole mxm board including the memory (which would include about 5 Watt).

Compared to the desktop ATI Radeon HD 4850, the mobile 4850 features a slower core clock and therfore should perform in the region of the desktop HD 4830.
