ati radeon hd 4850 vs amd radeon r7 m260

In addition to this, the software also supports dual video stream decoding and Picture-in Picture mode for full compliancy to the UVD BD-Live standards. UVD 2 supports full bitstream decoding of H.264/MPEG-4 AVC and VC-1 streams by the GPU, thus reducing workload from the CPU. The Mobility Radeon HD 4850 includes UVD 2, Avivo HD software and an onboard soundchip for 7.1 sound output over HDMI or DisplayPort.

Each of the five instructions of a VLIW bundle has to be independent from the others, so the overall performance is highly dependent on driver optimizations. The stream processors (also called ALUs) are grouped in five-way VLIW units. These cores do the graphics work previously done by dedicated shader and pixel pipelines of older GPUs. The mobile HD 4850 core is based on the RV770 chip and features 800 stream processors (or 160 5-dimensional shader cores). If DDR3 with a smaller 128 Bit memory bus is used instead, then this would bottlebeck the 5850 to performance levels closer to that of the Mobility HD 4850. The newer Mobility HD 5850 is noticeably faster than the Mobility HD 4850 if GDDR5 graphics memory is present. Compared to an Nvidia GeForce GTX 260M, the HD 4850 should be a bit faster on average. Demanding DirectX 10 games, such as Crysis, can be played with medium to high detail settings. The high amount of shaders and the wide 256 bit bus can allow the card to run practically every DirectX 9 game in high resolutions and details. The gaming performance of the ATI Mobility Radeon HD 4850 should be comparable to the desktop HD 4830 and is therefore very good at resolutions below 1080p. Technically, the GPU is based on the desktop HD 4850 GPU but with a lower clock rate for reduced energy consumption. The ATI Mobilty Radeon HD 4850 from AMD is a DirectX 10.1 upper middle-class notebook graphics adapter. ATI Mobility Radeon HD 4850 ► remove from comparison
