Intel Xeon E3-1565L v5 vs Intel Xeon E3-1585 v5: comparison
Comparison of Intel Xeon E3-1565L v5 and Intel Xeon E3-1585 v5: key differences and a full specification table.
Key differences
Intel Xeon E3-1565L v5 has a lower TDP (35 W vs 65 W).
At the same time, Intel Xeon E3-1585 v5 has a higher base clock (3.5 GHz vs 2.5 GHz), a higher maximum clock (3.9 GHz vs 3.5 GHz) and a higher maximum integrated graphics clock (1.15 GHz vs 1.05 GHz).
Both processors match on: core count (4), thread count (8), process node (14 nm), maximum memory size (64 GB), memory channels (2), 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.
