Intel Xeon E5-2448L vs Intel Xeon E5-2648L: comparison
Comparison of Intel Xeon E5-2448L and Intel Xeon E5-2648L: key differences and a full specification table.
Key differences
Intel Xeon E5-2648L has more memory channels (4 vs 3).
Both processors match on: core count (8), thread count (16), base clock (1.8 GHz), maximum clock (2.1 GHz), L3 cache (20 MB), TDP (70 W), process node (32 nm), maximum memory size (384 GB), 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.
