i7-3770 vs E5-2620 specifications comparison

The graphs below compare the most important Xeon E5-2620 and Intel Core i7-3770 characteristics. These features, as well as 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, provided by Hyper-Threading technology. The "Operating frequency" chart uses dark color to represent base frequency, while 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.

CPUIDs

The table below compares support for x86 extensions and technologies, as well as individual instructions and low-level features of the Intel Core i7-3770 and Intel Xeon E5-2620 microprocessors. Information in this table was retrieved from actual processors using CPUID instruction, and we also utilized internal timer to measure CPU frequency. Be aware that all technologies, disabled in BIOS or by a virtual machine, will be shown as not supported. Different steppings of Intel processors may also have slightly different features. In rare cases, measured frequency may differ from official specifications.
