Intel Xeon E5-2640 v4 vs Intel Xeon E5-2650 v4: comparison
Comparison of Intel Xeon E5-2640 v4 and Intel Xeon E5-2650 v4: key differences and a full specification table.
Key differences
Intel Xeon E5-2640 v4 has a higher base clock (2.4 GHz vs 2.2 GHz), a higher maximum clock (3.4 GHz vs 2.9 GHz) and a lower TDP (90 W vs 105 W).
At the same time, Intel Xeon E5-2650 v4 has more cores (12 vs 10), more threads (24 vs 20) and a larger L3 cache (30 MB vs 25 MB).
Both processors match on: process node (14 nm), maximum memory size (1.5 TB), memory channels (4), PCIe version (3).
These are specification values: they show differences between the models but do not determine a performance winner. For a specific workload, rely on independent benchmarks.
