Intel Xeon W-11855M vs Intel Xeon W-10885M: comparison

Comparison of Intel Xeon W-11855M and Intel Xeon W-10885M: key differences and a full specification table.

Key differences

Intel Xeon W-11855M has a larger L3 cache (18 MB vs 16 MB), a finer process node (10 nm vs 14 nm), a newer PCIe version (4 vs 3) and a higher maximum integrated graphics clock (1.45 GHz vs 1.25 GHz).

At the same time, Intel Xeon W-10885M has more cores (8 vs 6), more threads (16 vs 12) and a higher maximum clock (5.3 GHz vs 4.9 GHz).

Both processors match on: maximum memory size (128 GB), memory channels (2).

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.
