Intel's Pentium 4 570J - Will 3.8GHz do the trick?

The Test

In addition to our usual tests we've included PC World's WorldBench 5, an application based test suite much like Winstone and SYSMark that incorporates many popular applications. Unlike the aforementioned benchmarks, WorldBench does not test multitasking power, rather focusing on single application performance, making it very complementary to our existing benchmarks. The one thing to keep in mind about the WorldBench results is that the variation between test runs can be pretty significant; we do everything to make sure that the results are as consistent as possible (multiple runs, throwing out outliers, etc...) but the variation between runs in these tests can be as high as 6% - thus we would suggest looking at performance differences only greater than 10% in these tests for any sort of significance. The rest of the tests have variations between runs of 1 - 3%.

Our hardware configurations are similar what we've used in previous comparisons, with one addition - our Athlon 64 testbed now uses the recently released nForce4 chipset. For a review of that chipset read our own Wesley Fink's review of NVIDIA's latest chipset with SLI support.
