Intel Xeon E3-1220L vs Intel Xeon E3-1270: comparison
Comparison of Intel Xeon E3-1220L and Intel Xeon E3-1270: key differences and a full specification table.
Key differences
Intel Xeon E3-1220L has a lower TDP (20 W vs 80 W).
At the same time, Intel Xeon E3-1270 has more cores (4 vs 2), more threads (8 vs 4), a higher base clock (3.4 GHz vs 2.2 GHz) and a higher maximum clock (3.8 GHz vs 3.4 GHz).
Both processors match on: process node (32 nm), maximum memory size (32 GB), memory channels (2), PCIe version (2).
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.
