Warning: Last items in stock!
GeForce 8400M GT G86M G86-631-A2 is a upgraded graphic processor of G86-630-A2 and G86-603-A2 BGA chipset . so it can substitute G86-630-A2 and G86-603-A2 with more excellent performance.
NVidia GeForce 8400M GT G86-631-A2 is the DirectX 10 capable successor of the GeForce Go 7400 for laptops and technologically a slower 8600M GS video card. The performance is slightly above the 7400 and therefore it can represent current games fluently with reduced details / 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.
Compared to desktop graphics adapters, the 8400M GT is a bit slower than the 8500 GT (because of the lower memory speed).
