J. Dzhugashvili writes: Nvidia has already pulled the curtain off its Ion platform, which couples GeForce 9400 integrated graphics with Intel's Atom processor. But how does it perform? The Tech Report has taken the tiny Ion reference system for a spin in games and video decoding to see if the GeForce GPU really helps. The verdict? 1080p playback is actually smooth, and the whole system only draws 25W during playback. Fast-paced action games are another story—Half-Life 2, Quake Wars, and Call of Duty 4 are all choppy with a single Atom core and single-channel RAM, although they do run. TR concludes that Ion is nevertheless a clear improvement over Intel's 945G chipset, especially since Nvidia doesn't expect Ion-based Atom systems to cost significantly more than all-Intel ones.
