The Nvidia Ion chipset took the ultraportable computing world by storm this year. Now, as 2010 draws nigh, Ion 2 is getting closer and closer to its inaugural launch. Digitimes reports that the first Ion 2-based chip orders have been sent to Nvidia by Acer. These Ion 2 chips are designed to work with the new Intel Pineview Atom CPUs, due out in 2H of next year. Acer's most successful Ion-packing line has been the AspireRevo series of net-tops, and we look forward to seeing some Ion 2 Revos hit in 2010. The main difference between the Ion and Ion 2 chipset seems to be that the Ion 2 acts much more like a discrete GPU. This is due to the fact that Pine Trail M and D push memory control and IGP functions onto the CPU. Nvidia's also working on a version of the Ion for VIA's processors, but no more information on that project is available yet.Nvidia hasn't commented on any of this, but the timing works out right and Digitimes is usually spot-on about this sort of thing. More information about Ion 2 should start to hit as we roll into the new year.
