The Mobility Radeon HD 2700 (sometimes also called X2700) is a DirectX 10.0 middle class graphic card of ATI and probably an enhanced HD 2600 (same amount of Unified Shaders). According the performance, it shall compete with the NVIDIA GeForce 8600M GT and is a higher clocked HD 2600 (scarcely below the XT). This is not sufficient for exigent DirectX 10 games like Crysis or World in Conflict in high detail levels. With low or medium settings, a fluent gaming is possible. Elder games (like DirectX 9 games) can be played fluently with high details.
Due to the Avivo HD Videoengine the chip accelerates HD Video like HD DVD, Blue-ray (video decoder for H.264/AVC, VC-1, MPEG-1, MPEG-2, MPEG-4/DivX Video Codecs). Furthermore, PowerPlay 7.0 grants longer battery runtimes. The ATI Mobility Radeon HD 2700 is certified for Windows Vista (for Aero user interface).
Technically, the chip contains 120 Stream processors (24 5-dimensional Shader units), which can manage vertex-, geometric or pixelshader tasks automatically. Therefore DirectX 10.0 and the Shader Model 4.0 is supported. Another particularity is the the 256 bit wide ringbus.
Compared to the desktop HD 2600 cards, the Mobility HD2700 is between 2600 Pro and XT.
