NVIDIA GeForce 8400M G

NVIDIA GeForce 8400M G Image NVIDIA G86 Image
The GeForce 8400M G was a graphics card by NVIDIA, launched in May 2007. Built on the 80 nm process, and based on the G86 graphics processor, in its NB8M-SE variant, the card supports DirectX 10.0. The G86 graphics processor is an average sized chip with a die area of 127 mm² and 210 million transistors. Unlike the fully unlocked GeForce 8400 GS, which uses the same GPU but has all 16 shaders enabled, NVIDIA has disabled some shading units on the GeForce 8400M G to reach the product's target shader count. It features 8 shading units, 8 texture mapping units and 4 ROPs. NVIDIA has placed 256 MB GDDR3 memory on the card, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 400 MHz, memory is running at 400 MHz.
Its power draw is rated at 10 W maximum. GeForce 8400M G is connected to the rest of the system using a PCIe 1.0 x16 interface.
