Intel Xeon L5630 vs Intel Xeon L5638: comparison

Comparison of Intel Xeon L5630 and Intel Xeon L5638: key differences and a full specification table.

Key differences

Intel Xeon L5630 has a higher base clock (2.13 GHz vs 2 GHz) and a lower TDP (40 W vs 60 W).

At the same time, Intel Xeon L5638 has more cores (6 vs 4) and more threads (12 vs 8).

Both processors match on: maximum clock (2.4 GHz), process node (32 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.
