Intel Xeon D-1622 vs Intel Xeon D-1637: comparison
Comparison of Intel Xeon D-1622 and Intel Xeon D-1637: key differences and a full specification table.
Key differences
Intel Xeon D-1622 has a lower TDP (40 W vs 55 W).
At the same time, Intel Xeon D-1637 has more cores (6 vs 4), more threads (12 vs 8) and a higher base clock (2.9 GHz vs 2.6 GHz).
Both processors match on: maximum clock (3.2 GHz), process node (14 nm), maximum memory size (128 GB), memory channels (2), 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.
