Intel Xeon E5-2440 vs Intel Xeon E5-2470: comparison
Comparison of Intel Xeon E5-2440 and Intel Xeon E5-2470: key differences and a full specification table.
Key differences
Intel Xeon E5-2440 has a higher base clock (2.4 GHz vs 2.3 GHz).
At the same time, Intel Xeon E5-2470 has more cores (8 vs 6), more threads (16 vs 12), a higher maximum clock (3.1 GHz vs 2.9 GHz) and a larger L3 cache (20 MB vs 15 MB).
Both processors match on: TDP (95 W), process node (32 nm), maximum memory size (384 GB), memory channels (3), PCIe version (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.
