Intel Xeon E5-2408L v3 vs Intel Xeon E3-1278L v4: comparison
Comparison of Intel Xeon E5-2408L v3 and Intel Xeon E3-1278L v4: key differences and a full specification table.
Key differences
Intel Xeon E5-2408L v3 has a lower TDP (45 W vs 47 W), a higher maximum memory size (384 GB vs 32 GB) and more memory channels (3 vs 2).
At the same time, Intel Xeon E3-1278L v4 has a higher base clock (2 GHz vs 1.8 GHz) and a finer process node (14 nm vs 22 nm).
Both processors match on: core count (4), thread count (8), 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.
