NVIDIA GeForce GTS 350M
The Nvidia GeForce GTS 350M is a high performance laptop graphics card and based on the GT215 core. According to the released information by Nvidia the card is identical to the GeForce GTS 250M. However, in the Toshiba A663-3DV the clock rate is a bit lower (450/1080MHz).
The GT215 core supports DirectX 10.1 and OpenGL 2.1. It features 96 shader cores as the 9800M GT, but the memory bus is only 128 bit wide. To compensate this, the GTS 350M supports GDDR5. Therefore, the performance is significantly lower when cheap DDR3 memory is used.
As the GeForce 9800M GT, the laptop graphics card GTS 350M features 96 stream processors that do the work of the former dedicated pixel- and vertex-shaders. The unified shaders of Nvidia are 1-dimensional (AMD has 5-dimensional shaders which leads to the higher number of shaders).
The GeForce GPU also supports CUDA, DirectX Compute, OpenCL, and PhysX to use the shaders for other tasks than rendering images (like encoding videos, calculating the physics of a game or mathematical tasks). For these special tasks, the GPU can be noticeably faster than current CPUs.
The mobile graphics card has a built in video decoder called PureVideo HD with VP4. The Video Processor 4 (VP4) supports the full decoding of H.264, VC-1, and now also MPEG-4 ASP (e.g. DivX or XviD). MPEG-1 still wont be supported, but the decoding of this codec is quite trivial on a CPU.
In conjunction with a chipset from Nvidia with integrated graphics (e.g. 9400M), the GTS 350M supports Hybrid-SLI (HybridPower but no GeForceBoost). HybridPower is a technique to choose between the integrated and dedicated graphics core, if performance or battery runtime is needed. This works only in Windows Vista (and possibly Windows 7). Up to now the user has to use a tool to switch between the GPUs. Later Nvidia wants to switch automatically in the drivers. GeForceBoost is not supported by the GTS 360M because the SLI combination would not perform better.
The performance of the middle class - high end GPU GeForce GTS 350M should be on par compared to the GTS 250M. Demanding DirectX 10 games like Crysis should run fluently in medium to high details. Older or less demanding games should run in high detail settings and high resolutions.
Depending on the the used type of graphics memory (GDDR5, GDDR3) the performance may differ. The maximum clock rate can also differ according to the used graphics RAM. The maximum support clock rate is 2000 MHz for GDDR5.
