Intel Xeon E5-4640 v3 vs Intel Xeon E5-4667 v3: comparison
Comparison of Intel Xeon E5-4640 v3 and Intel Xeon E5-4667 v3: key differences and a full specification table.
Key differences
Intel Xeon E5-4640 v3 has a lower TDP (105 W vs 135 W).
At the same time, Intel Xeon E5-4667 v3 has more cores (16 vs 12), more threads (32 vs 24), a higher base clock (2 GHz vs 1.9 GHz) and a higher maximum clock (2.9 GHz vs 2.6 GHz).
Both processors match on: process node (22 nm), maximum memory size (768 GB), 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.
