Intel Xeon E7520 vs Intel Xeon E7530: comparison
Comparison of Intel Xeon E7520 and Intel Xeon E7530: key differences and a full specification table.
Key differences
Intel Xeon E7520 has a larger L3 cache (18 MB vs 12 MB) and a lower TDP (95 W vs 105 W).
At the same time, Intel Xeon E7530 has more cores (6 vs 4), more threads (12 vs 8) and a higher maximum clock (2.13 GHz vs 1.87 GHz).
Both processors match on: base clock (1.87 GHz), 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.
