The Intel Xeon L5640 @ 2.27GHz is newer than Intel Xeon X5677 @ 3.47GHz, while Intel Xeon X5677 @ 3.47GHz is around 8% faster in multi-threaded (CPU Mark) testing, it is around 31% faster in single-thread testing. However, Intel Xeon L5640 @ 2.27GHz uses substantially less power. All the CPUs in this comparison belong in the Server CPU Class.The values below were tabulated from a combined 130 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.
