Setup:
AMD Phenom II X4 920 @ 2.80GHz, 4 x cores
2x 2GB 1066MHz memory modules
Intel Q9450 @ 2.66GHz, 4 x cores
2x 2GB 1066MHz memory modules
Intel Core i7 920 @ 2.66GHz, 4 x cores
3x 1GB 1333MHz memory modules
NVIDIA GeForce 9800 GTX / 512MB DDR3 (irrelevant since we are not doing graphics testing)
Seagate ST3500320AS 500GB drive
Ubuntu 8.10
Desktop set to 1680 x 1050
Version 1.6.0 of the test suite
Running these tests inside a GNOME environment
I have compiled my own XML suite using various tests that use all the cores in the chip, plus some memory tests.
Full results of the benchmarks here:

Summary below:
I have found the memory-bandwidth test in Phoronix very inconsistant. I think it is version 0.13. In the tests above I have downloaded version 0.15 and run it manually. It is actually a 32-bit application and won't compile on 64-bit systems.
I have also tested the Core i7 with 3 x 1GB 1600MHz modules (Uncore is 3200MHz). However, it actually performed slightly slower. Not sure why. Could be the motherboard.
With the Core i7, Intel Turbo Technology is enabled in the BIOS, which means the processor actually runs at a multiplier of 21x instead of 20x. So the processor actually runs at 2.793GHz.
