Intel Xeon E7520 vs Intel Xeon X3430: comparison
Comparison of Intel Xeon E7520 and Intel Xeon X3430: key differences and a full specification table.
Key differences
Intel Xeon E7520 has more threads (8 vs 4) and a larger L3 cache (18 MB vs 8 MB).
At the same time, Intel Xeon X3430 has a higher base clock (2.4 GHz vs 1.87 GHz) and a higher maximum clock (2.8 GHz vs 1.87 GHz).
Both processors match on: core count (4), TDP (95 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.
