Wouldn't a 50% increase in GPU performance still be too little, too late for Intel?
Well, all the thing is designed to do is power the GUI, the graphical interface you click and interact with, along with offering some hardware acceleration with video. It's still not targeting games.
This is almost getting cliche because everyone references this exact argument, but it's so true... 50% of a small number is still a tiny number. A 50% gain on 6FPS would mean it got 9FPS... or 16FPS becomes 24FPS... it's honestly just not going to matter. Intel has gotten used to spinning the numbers/marketing to try and gloss over their IGP's shortcomings.
Still, I'm looking forward to Arrandale simply for the power savings it should bring... Core 2 Duo's lack Nehalem's power gating and PCU controller. Arrandale will not only be smaller, but will be able to shut parts of itself off and manage its own power states better. Removing the northbridge should only help lower the system power consumption too...
