First Northwood review online It's from a 2.2 GHz Northwood overclocked to 2.66 GHz (133 MHz FSB). But it already allows some interesting comparisons & observations: - the synthetical scores from Sandra are exactly 33% higher than a 2 GHz Willamette suggesting no major architectural changes (Sandra always scales linear with frequency on a given architecture) except twice the L2 cache - SuperPi is with 67sec on par with an Athlon XP 1900+ (not overclocked); it's about 30% faster than a 2 GHz P4 suggesting good scaling with clock-speed (see www16.big.or.jp - 3Dmark 2001 is only around 5% faster compared to a 2 GHz P4 (see sharkyextreme.com suggesting that this benchmark is more videocard limited - CPumark '99 is more than 50% faster on the reviewed Northwood compared to a 1.8 GHz which is a little bit better than linear scaling (note that CPumark is also a synthetic benchmark which scores almost linear with frequency); it's probably roughly on par with a 1.6 GHz Athlon XP (see active-hardware.com Overall it's hard to make conclusions based on the limited data and the obscure benchmarks. But it looks like that Northwood won't benefit that much over Willamette clock-for-clock. Andreas
