Intel Core i3-1120G4 vs Intel Xeon W-11855M: comparison
Comparison of Intel Core i3-1120G4 and Intel Xeon W-11855M: key differences and a full specification table.
Key differences
Intel Xeon W-11855M has more cores (6 vs 4), more threads (12 vs 8), a higher maximum clock (4.9 GHz vs 3.5 GHz) and a larger L3 cache (18 MB vs 8 MB).
Both processors match on: process node (10 nm), memory channels (2), 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.
