Intel Xeon L3406 vs Intel Xeon L5609: comparison

Comparison of Intel Xeon L3406 and Intel Xeon L5609: key differences and a full specification table.

Key differences

Intel Xeon L3406 has a higher base clock (2.26 GHz vs 1.86 GHz), a higher maximum clock (2.53 GHz vs 1.86 GHz) and a lower TDP (30 W vs 40 W).

At the same time, Intel Xeon L5609 has more cores (4 vs 2), a larger L3 cache (12 MB vs 4 MB), a higher maximum memory size (288 GB vs 16.38 GB) and more memory channels (3 vs 2).

Both processors match on: thread count (4), 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.
