Gaming Performance of PowerBook G4/800

Accelerate Your Mac! recently posted some information submitted by readers regarding their experience with Apple's new 800 MHz PowerBook G4. Among the features tested is the performance of the newly included ATI Mobility Radeon 7500, an upgrade of particular importance to gamers:
Quake3 1.31b5 tests in OS X showed slightly better than Apple's quoted 68FPS at 1024x768/32bit HQ settings. (69.x FPS). I applied the 's_chunksize 4096' tweak I've noted in some past AGP card reviews and saw 77.8 FPS at that resolution. The PB G4/667 with Radeon Mobility (16MB ddr) scored about 34FPS in that same test with no tweaks - so the PB G4/800 w/7500 mobility has twice the Quake3 1024x768/32bit performance of the previous 667 model.These are impressive numbers to be sure, and really show off the power of the Mobility Radeon 7500 with its 32 MB of VRAM versus the previously used Mobility Radeon with its 16 MB.
Other features looked at include Airport range, the heat factor, and screen performance. Those interested in the full report can find it at Accelerate Your Mac!
