Intel Xeon W-3345 vs Intel Xeon W-3365: comparison
Comparison of Intel Xeon W-3345 and Intel Xeon W-3365: key differences and a full specification table.
Key differences
Intel Xeon W-3345 has a higher base clock (3 GHz vs 2.7 GHz) and a lower TDP (250 W vs 270 W).
At the same time, Intel Xeon W-3365 has more cores (32 vs 24) and more threads (64 vs 48).
Both processors match on: maximum clock (4 GHz), process node (10 nm), maximum memory size (4 TB), memory channels (8), PCIe version (4).
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.
