Hexus had an interview with Rene Haas, the general manager of NVIDIA's notebook GPU business. They mainly talked about NVIDIA's Ion platform, which is a GeForce 9400M based solution for the Intel Atom processor.
Surely there must have been some compromises on power and performance. "The TDP [thermal design power] is in the 12 watt range, giving the total solution a power draw of 16 watts, compared to 12 watts for existing Atom solutions. And for that you get ten times the performance."
What about Atom? Surely the full capabilities of the 9400M are inhibited by such a low power CPU. "There's not much of a bottle neck with the current single core Atom compared to the dual core notebook CPU - approximately 30 percent lower on 3d Mark," said Haas.
"An Ion system can do full HD playback without skipping and still not have full CPU utilisation. Apart from decryption the GPU does pretty much everything."
