Hardware France and amddiyoc have some early Pentium 4 Northwood benchmarks. Altavista and Dictionary.com both have translators, if you are interested in more than the benchmarking screen shots.
The Northwood has a 0.13 micron core and has a L2 cache twice the size (512kb) of the Willamette and is designed to run over 2Ghz. The Northwood will also consume less voltage and produce less heat.
