AMD's next-gen laptop graphics chips, the 'M96' and the 'M98-L', have been approved by the PCI SIG - the body that oversees the PCI Express bus.

The parts follow on from M86 and M88, AMD's Radeon Mobility 3800 series GPUs, the most recent of which, the 3850, was only launched last month.

M96 and M98-L will be mobile equivalents of the 'RV770' desktop GPU that (also) debuted last month, as the Radeon HD 4800 series.

Having only just announced the 3850, it seems unlikely that the 4850 would debut in the near future, and indeed a late Q3/early Q4 release window is the one most being talked about.
