Following today's launch of Intel's new Santa Rosa platform, Nvidia is unveiling their new GeForce 8M series aimed at the low-end and mainstream mobile market segments with the G84M and G86M respectively. The Nvidia GeForce 8M Series of notebook graphics processors are said to be the first to support DirectX 10.

The key parts are the GeForce 8400M G, GS and GT, and the 8600M GS and GT. Moving along the line, the chips contain eight, 16, 16, 16 and 32 unified shader units, respectively. The cores are each clocked at 400, 400, 450, 600 and 475MHz.

The 8400Ms connect to up to 256MB of memory across a 64-bit bus, the 8600Ms to 512MB of VRAM across a 128-bit bus. The five chips' memory clocks are set to 600, 600, 600, 700 and 700MHz, respectively.
Nvidia claims the 8M chips can do H.264 video decoding freeing the CPU for other tasks and significantly reducing power consumption, heat and noise; also achieving up to twice the performance of previous generation GPUs. PC buyers can expect the 8M series in the latest Centrino Duo and Centrino Pro laptops due to arrive over the coming months.
