Intel Xeon X6550 vs Intel Xeon W3565: comparison
Comparison of Intel Xeon X6550 and Intel Xeon W3565: key differences and a full specification table.
Key differences
Intel Xeon X6550 has more cores (8 vs 4), more threads (16 vs 8) and a larger L3 cache (18 MB vs 8 MB).
At the same time, Intel Xeon W3565 has a higher base clock (3.2 GHz vs 2 GHz) and a higher maximum clock (3.46 GHz vs 2.4 GHz).
Both processors match on: TDP (130 W), process node (45 nm).
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.
