The Intel Xeon E5-2666 v3 @ 2.90GHz is newer than Intel Xeon E5-2680 v3 @ 2.50GHz, while Intel Xeon E5-2680 v3 @ 2.50GHz is around 6% faster in multi-threaded (CPU Mark) testing, but Intel Xeon E5-2666 v3 @ 2.90GHz is around 8% faster in single-thread testing. However, Intel Xeon E5-2666 v3 @ 2.90GHz uses around 12% more power. All the CPUs in this comparison belong in the Server CPU Class.The values below were tabulated from a combined 647 benchmarks submitted from our PerformanceTest software and results and are updated daily to include new submissions.
- The first section will show basic information for each CPU selected.
- The additional graphs shows the CPU Mark and Single Thread values of each CPU selected.
- An accompany graph, if price data is available, will shows the value for money, in terms of the
CPU Mark/Thread Rating per dollar.
- The last section will show approximate yearly running costs for the CPUs.
