NVIDIA GeForce 8400M GS vs vs Vivante GC800
NVIDIA GeForce 8400M GS
► remove from comparisonNVidia GeForce 8400M GS is the DirectX 10 capable successor of the GeForce Go 7400 for laptops and technologically a slower 8400M GT video card (because of the smaller 64 Bit memory bus). The performance is slightly above the 7400 and, therefore, it can represent current (not very demanding) games fluently with reduced details / resolutions. Demanding games like Crysis can only be run in very low details and resolutions. For people who play occasionally, it may be sufficient.
The particularity of this video card are the "Unified Shader". Pixel- and vertex-shaders do not exist any more but 16 of the so called stream processors do the graphic work.
One advantage of the GeForce 8000 series is the integrated PureVideo video processor. It can support the CPU in decoding H.264, VC-1, MPEG2, and WMV9 encoded videos in HD quality > PureVideo Product Comparison
Compared to desktop cards, the 8400M GS can be compared to the 8400 GS which has a 50 MHz higher core clock (and is therefore a bit faster).
Vivante GC800
► remove from comparisonThe Vivante GC800 is an integrated graphics card for ARM based (e.g. Rockchip RK291x) and MIPS based (e.g. Actions ATM701x) SoCs. It offers a single VEC-4 (or in other words four VEC-1) unified shaders and supports OpenGL ES 2.0 (optional ES 3.0), OpenGL 2.0, OpenVG 1.1, DirectX 9_3 (optional) and OpenCL 1.2 (optional). The clock rate can be choosen between 315 and 575 MHz in 40nm designs and up to 800 MHz in 28nm designs.
