Doom 3 Benchmarks
Doom 3 is a single-threaded game that thrives on system memory bandwidth and a powerful graphics card. Let's see how thing stack up in this scenario.
As expected, the Pentium Extreme Edition 840 performs a lot like a 3.2GHz P4 540J, since it's cores have the same clock speed. There is perhaps a slight advantage shown for the new Pentium EE 840 here, as other system resource calls are probably handled more fluidly with the new Dual Core Pentium EE 840 but the benefits are negligible.
