In the multi-threaded workload, AMD looks much better, as the triple- and quad-cores are competitive.
Interestingly, average power between the fastest AMD and Intel processors is actually even. It’s two cores against four, 3.33/3.60 GHz against 2.5 GHz.
Total power used is again a bit lower on the Intel machines, but the AMD quad-core comes very close. This proves impressively that a quad-core CPU provides better performance per watt when it's kept occupied.
