Intel Xeon W-2255 vs Intel Xeon W-2265: comparison
Comparison of Intel Xeon W-2255 and Intel Xeon W-2265: key differences and a full specification table.
Key differences
Intel Xeon W-2255 has a higher base clock (3.7 GHz vs 3.5 GHz).
At the same time, Intel Xeon W-2265 has more cores (12 vs 10), more threads (24 vs 20) and a higher maximum clock (4.6 GHz vs 4.5 GHz).
Both processors match on: TDP (165 W), process node (14 nm), maximum memory size (1 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.
