ATI Mobility Radeon HD 3670
The AMD ATI Mobility Radeon HD 3670 is a laptop graphics card and technically a higher clocked HD 3650 with clock rates nearly as high as the old 2600 XT. Compared to it, the HD 3650 should be cooler (55nm process) and features DirectX 10.1 support.
The 3D performance of the HD 3670 is on average a bit better than the old Nvidia GeForce 8600M GT. Therefore, old DirectX 9 games should be fully playable with mostly high details. Modern demanding games are only playable with minimum-modest detail settings and resolutions (e.g. Crysis 1).
120 Stream processors (48 5-dimensional Shader units) manage the tasks of the Shader and Pixel pipelines. Due to the 5-dimensional structure, the amount of shaders can not be directly compared to Nvidia graphics cards.
Due to Avivo HD video engine the graphic card can support the processor with several HD video operations. VC-1 and H.264 can be fully decoded using the graphics card. MPEG-1, MPEG-2 and DivX can be accelerated using Motion Compensation and IDCT using the UVD on the graphics card.
Compared to the desktop HD 3670, the Mobility HD 3670 has a slower clock rate and should perform more like a desktop HD 3650.
