Intel Xeon E5-2648L vs Intel Xeon E5-2658: comparison
Comparison of Intel Xeon E5-2648L and Intel Xeon E5-2658: key differences and a full specification table.
Key differences
Intel Xeon E5-2648L has a lower TDP (70 W vs 95 W).
At the same time, Intel Xeon E5-2658 has a higher base clock (2.1 GHz vs 1.8 GHz) and a higher maximum clock (2.4 GHz vs 2.1 GHz).
Both processors match on: core count (8), thread count (16), L3 cache (20 MB), process node (32 nm), maximum memory size (384 GB), memory channels (4), 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.
