Intel Xeon EC5539 vs Intel Xeon EC5549: comparison

Comparison of Intel Xeon EC5539 and Intel Xeon EC5549: key differences and a full specification table.

Key differences

Intel Xeon EC5539 has a lower TDP (65 W vs 85 W).

At the same time, Intel Xeon EC5549 has more cores (4 vs 2), more threads (8 vs 2), a higher base clock (2.53 GHz vs 2.27 GHz) and a larger L3 cache (8 MB vs 4 MB).

Both processors match on: process node (45 nm), memory channels (3), PCIe version (2).

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.
