Intel Xeon E6510 vs Intel Xeon E7520: comparison
Comparison of Intel Xeon E6510 and Intel Xeon E7520: key differences and a full specification table.
Key differences
Intel Xeon E7520 has a higher base clock (1.87 GHz vs 1.73 GHz), a higher maximum clock (1.87 GHz vs 1.73 GHz), a larger L3 cache (18 MB vs 12 MB) and a lower TDP (95 W vs 105 W).
Both processors match on: core count (4), thread count (8).
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.
