Simplified, the Avivo HD technology handles all video tasks and enables the GPU to decode HD videos.ĪMD published a current consumtion of about 15-25 Watt for the HD 4650.

In addition to this, it also supports dual video stream decoding and Picture-in Picture mode which makes the UVD full BD-Live compliant. This UVD 2 supports full bitstream decoding of H.264/MPEG-4 AVC and VC-1 streams. The Mobility Radeon HD 4650 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). However, cards that use that kind of memory will be slower than others equipped with GDDR RAM.

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.Ī speciality of the Radeon HD 4600 Series is the possibility to use ordinary DDR2 and DDR3 graphic memory (as a cheaper alternative to GDDR3). The stream processors are also called ALUs and are grouped in five-way VLIW units. These cores do the graphic work of the shader- and pixel pipelines of older GPUs. The Mobility HD 4650 is based on the RV730 chip and features 320 stream processors (64 5-dimensional shader cores). Demanding DX10 games from 2008 like Crysis run only in low-medium details fluently. Most DirectX 9 games (like Call of Duty 4, F.E.A.R., or Unreal Tournament 3) should be playable in medium to high details (in 1024x768). The gaming performance of the GPU lies a bit below the HD 4670. Later the HD 4650 was also introduced as Mobility Radeon HD 5165. The successor of the HD 4650 is the Mobility Radeon HD 5650 with DirectX 11 support and improved performance. Technically it is a slower clocked Mobility Radeon HD 4670.
The ATI Mobilty Radeon HD 4650 from AMD is a DirectX 10.1 middle-class notebook graphics adapter.
