NVIDIA GeForce 9100M G
The Nvidia GeForce 9100M G is a DirectX 10 capable onboard (shared memory) graphics adapter (or mGPU = motherboard GPU) for laptops. The core is based on the 9200M GS but without dedicated memory. In conjunction with dedicated 9x00M graphic cards the 9100M G supports GeForceBoost to enhance the performance. The combination with 9200M GS / 9300M GS is called GeForce 9400M.
The 9100M Gt integrates the new VP3 video processor (8400M, 9300M G had VP2) with more video features and better hd-video decoding support.
In conjunction with the 9200M GS / 9300M GS, the 9100M G integrated graphics supports Hybrid-SLI (HybridPower and 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. 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 uses the integrated graphics core of the 9100M G and the dedicated of the 9200M / 9300M in SLI mode to achieve better frame rates.
As the 9200M GS, the 9100M G features 8 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).
Compared to the old 8400M G, the performance of the 9100M G is nearly equal. Modern DirectX 10 games will run only in low details and resolutions (if fluent). Older DirectX 9 games, like HalfLife 2 or Far Cry run fluently in medium details.
The 9100M G chipset should be similar to the desktop GeForce 9100 chipset graphics.
