Intel Xeon W-1250P vs Intel Xeon W-1270: comparison
Comparison of Intel Xeon W-1250P and Intel Xeon W-1270: key differences and a full specification table.
Key differences
Intel Xeon W-1250P has a higher base clock (4.1 GHz vs 3.4 GHz).
At the same time, Intel Xeon W-1270 has more cores (8 vs 6), more threads (16 vs 12), a higher maximum clock (5 GHz vs 4.8 GHz) and a larger L3 cache (16 MB vs 12 MB).
Both processors match on: process node (14 nm), maximum memory size (128 GB), memory channels (2), PCIe version (3), maximum integrated graphics clock (1.2 GHz).
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.
