NVIDIA released their 9400GT a few short months ago to target the higher end of the market that the HD 4550 is at. Due to the release of the HD 4550 and HD 4350 NVIDIA decided to redo their lineup making the 9400GT the lowest end of the 9xxx series lineup. The 9400GT is based upon NVIDIA’s G96 chip and has 16 Stream Processors. It is manufactured on TSMC’s 65 nanometer process and is well targeted for the low-end of the market.
The key features of the 9400GT include support for DirectX 10.0. Virtually every game released from now on will have some support for DirectX 10.0 and the 9400GT is there if you need real support. Important features like Pixel Shader 4.0 and Geometry Shaders are the important features of DX 10.0. I won’t rehash the argument of DX10.0 versus DX10.1.
Ageia was the first hardware company to market a “Physics Processing Unit” on the graphics card with their Ageia PhysX card. NVIDIA bought Ageia a few months ago and have released at least two drivers with support for PhysX on NVIDIA video cards of the 8xxx series and above. Games like Gears of War and Unreal Tournament 3 take advantage of the offloading of the game physics to the graphics card.
NVIDIA’s HD decoder is called PureVideo HD. This is both a hardware and software solution that can do almost everything that the bigger brother GTX280 can include picture in a picture dual streaming capability. NVIDIA introduced Dynamic Contrast Enhancement to sharpen contrasts when the decoder detects dull image. PureVideo HD is NVIDIA’s answer to UVD on the ATI side of things.
