Intel Xeon EC5509 vs Intel Xeon LC3528: comparison
Comparison of Intel Xeon EC5509 and Intel Xeon LC3528: key differences and a full specification table.
Key differences
Intel Xeon EC5509 has more cores (4 vs 2), a higher base clock (2 GHz vs 1.73 GHz), a larger L3 cache (8 MB vs 4 MB) and more memory channels (3 vs 2).
At the same time, Intel Xeon LC3528 has a lower TDP (35 W vs 85 W).
Both processors match on: thread count (4), process node (45 nm), 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.
