There's a first Quake3-Benchmark with a Pre-Production 800 MHz Clawhammer-CPU. They compared it to a 1600 MHz P4 and a Athlon XP 2000+. Funny thing is that the Clawhammer (183 FPS) beats the P4 (182 FPS). Only the Athlon is faster (210 FPS)! Read the whole thing at Tecchannel.de (german and english version available).
