We wrote about ION 2 last year and back then it was quite clear that ION 2 is not chipset, but actually a GPU that will interconnect with Intel's Pine Trail M platform.

Since Intel has important parts of its chipset inside of the Pine View M processor, Nvidia simply didn’t see any sense in putting the replacement chipset next to Intel’s own. ION 2 will take care of graphics subsystem and it should work together with Intel’s IGP in the so-called Optimus technology mode.

Many vendors are expected to embrace ION 2, but the fact that ION 2 makes netbooks with latest N4x0 generation Atoms more expensive doesn’t really help. The performance in this case comes at a price and Nvidia will also play the compute and Cuda card, as this is definitely going to run better on ION 2 than on Intel’s CPU integrated IGP.

If you didn't get this by now, the ION brand will remain reserved exclusively for Nvidia GPUs and chipsets that support Atom CPUs.
