[citation][nom]jhansonxi[/nom]Phoronix posted a review of the ZaReason Ion Breeze 3770 which is a 9400M nettop (compact desktop) but it would be interesting to see netbook performance and battery life with it.[/citation]
There have been tests and benches done on the ion platform here at toms and other sites.
The performance only benefits gaming and 1080p or blueray playback.
HD videocontent upto 720p and 9Mbps can be played back with the intel 945/950 chipset pretty fine; although it does not have the capability to do some post processing on lower quality video's.
HD Flash seemed to be a problem for both, and there where the Atomprocessor with Intel chipset worked fine on 800x600 screen resolution, the Ion does fine on 1024x768 resolution in gaming.
You would not notice that much difference though, because a general netbook screen is 1024x600. The intel, slightly too slow to get fluid screen reso in this settings, the nvidia slightly too powerful.
The NVidia 9400M graphics processor at games was said to have slightly too much graphics power for the Atom single core to follow in certain games (The atom N270 shows to be the bottleneck).
As for power requirements, if battery life on the intel system equals 4,2hours, battery life on the ion system equals 3,8 hours.
NVidia would do well in creating a new graphics card, more optimized for power consumption and for pairing with the Atom processor.
Perhaps lowering GPU/VRAM speeds will not affect gaming performance that much to the point where a balance is found.
What good is having many stream processes when the atom is only able to feed 3/4s of them?
