Testing and Results
Benchmarking processors is difficult, since it's hard to isolate the CPU performance from the rest of the system. This is especially true when testing the performance several processors across multiple platforms, since things like the motherboard and chipset used will affect the results. In this review I'm running various synthetic and application benchmarks across three different platforms: Intel P55, Intel X58, and AMD 890FX. As one example of the differences between these platforms, the P55 and 890FX use dual-channel memory, while the X58 platform uses triple-channel memory and thus benefits from higher memory bandwidth.
Still, the tests are valid in the sense that anyone using an Intel Core i7-930 will be using it in an X58 system, while Core i5-860 and AMD 965BE processors will likewise be on motherboards with their respective chipsets and architectures. Most of the benchmarks I've chosen should favor raw CPU performance, and I've tried to minimize the intra-system variables by using the same memory, hard disk, and video card for all three platforms. But be aware that it's impossible to completely isolate a processor from the rest of its system in these tests.
All processors were tested at their stock clock rates, but I also tested the Phenom II X6 1075T processor at the highest stable overclock I could achieve, 4.15GHz. This overclock was with the Turbo Core feature disabled, since I like to reach the highest speed all cores can sustain, and Turbo Core could cause the system to crash when it suddenly ramps up the CPU multiplier.
