Benchmarks of NVIDIA's upcoming NV28M mobile graphics processor have popped up over at AnandTech. The NV28M is essentially a mobile version of the GeForce4 Titanium graphics chip running at a reduced clock speed of 200MHz. Even at that clock speed, it's still able to run away from ATI's Mobility Radeon 9000 in 3D performance tests, though power consumption appears to be a weakness.
NV28's high power consumption will likely make short work of current notebook batteries if you're gaming, but I have to wonder just how much notebook gaming is done without a wall socket nearby. Perhaps mobile, but powerful chips like the NV28M will usher in a new class of notebooks specifically built for portable gaming. As long as it's more portable and cheaper than one of Shuttle's cubes and an LCD monitor, there might just be a market for it.
