Intel Xeon E5520 vs E5607

Mini Review

Intel Xeon E5520 advantages

  • This processor incorporates Hyper-Threading technology, which allows each CPU core to execute two threads simultaneously.

Intel Xeon E5607 advantages

  • The microprocessor features Advanced Encryption Standard (AES) instructions, that provide AES encryption acceleration. The technology is useful if you need to protect your disk or network data.

E5520 vs E5607 specifications comparison

The charts below compare the most important characteristics of the Intel Xeon E5607 and Xeon E5520 microprocessors. These features, together with an IPC (instructions per cycle) number, determine how well a processor performs. The "Number of cores / threads" graph shows the number of cores (darker area). Lighter area on the graph corresponds to the number of extra threads, offered by Hyper-Threading technology. The "Operating frequency" chart uses dark color for base frequency, whereas lighter area is for additional frequency, provided by Turbo feature. Darker area on the "On-chip cache" graph is for the On-chip L2 cache. Lighter area is for the L3 cache cache. Although the L3 cache cache is usually larger than the On-chip L2 cache, it is always slower.
