SimHQ has posted some info, mostly from press releases, on ATI's newest mobile chip, the Mobility Radeon 9000. Extreme Tech goes a bit further already offering benchmarks. It's faster than the mobile GeForce4 but not much, though it does offer pixel and vertex shaders. Update: There's also a HardOCP article on ATI's mobile chip. It includes an interesting quote from John Carmack about the performance (basically, good stuff for a laptop).
