ATI is finishing a new mobile GPU for desktop replacement notebooks, the Mobility Radeon X1600 (M56).
This GPU is based on the RV530 design and features about twelve pipelines and possibly four TMUs like its desktop brother but the memory will be limited to 128 bit.
It will be powerful enough to provide you very good performance in this notebook segment and it has all you need for high end games. M56, Mobility Radeon X1600 of course supports all the features of Shader Model 3.0 and we heard that the power consumption of the chip will be very good.More info over here.
ATI already won some thirty OEM designs and will go live with this any day now. We know that M56 is a killer part in this market segment. Its power consumption is very favourable as it is built on a 90 nanometres process and it won't mean that twelve pipelines in the notebook have to burn your hand and warm the whole keyboard. At least we hope so.
