Googlish: Source. While the new ION 2 (basically, a GT218 with 16 shaders) uses dedicated DDR3 memory (so it should have higher bandwidth), in communicates with the CPU/NB through a single, 1x PCI-Express lane. This single lane factor could be choking the system's performance, and it's not something that nVidia can solve, since this is a limitation from the Pineview architecture. I heard rumours that nVidia would be overclocking this single PCI-Express lane, but it doesn't seem to be making to much of a difference. The GPU in ION 1 was in the northbridge, so it connected with the CPU at much higher speeds. So it doesn't matter how powerfull the GPU in future ION systems can get, the single lane bottleneck will render it inefficient. I guess this could very well mean the end of nVidia's netbook history. The only thing nVidia has left is to apologize to VIA and use the ION 2 with Nano CPUs, if these will ever get relevant design wins.
