Intel Xeon E3-1275 v5 vs Intel Xeon E3-1285L v4: comparison
Comparison of Intel Xeon E3-1275 v5 and Intel Xeon E3-1285L v4: key differences and a full specification table.
Key differences
Intel Xeon E3-1275 v5 has a higher base clock (3.6 GHz vs 3.4 GHz), a higher maximum clock (4 GHz vs 3.8 GHz) and a higher maximum memory size (64 GB vs 32 GB).
At the same time, Intel Xeon E3-1285L v4 has a lower TDP (65 W vs 80 W).
Both processors match on: core count (4), thread count (8), process node (14 nm), memory channels (2), PCIe version (3), maximum integrated graphics clock (1.15 GHz).
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.
