Intel Xeon E5620 vs Intel Xeon E5507: comparison
Comparison of Intel Xeon E5620 and Intel Xeon E5507: key differences and a full specification table.
Key differences
Intel Xeon E5620 has more threads (8 vs 4), a higher base clock (2.4 GHz vs 2.26 GHz), a larger L3 cache (12 MB vs 4 MB) and a finer process node (32 nm vs 45 nm).
Both processors match on: core count (4), TDP (80 W), memory channels (3).
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.
