Intel Xeon E3-1285 v4 vs Intel Xeon E3-1285L v4: comparison
Comparison of Intel Xeon E3-1285 v4 and Intel Xeon E3-1285L v4: key differences and a full specification table.
Key differences
Intel Xeon E3-1285 v4 has a higher base clock (3.5 GHz vs 3.4 GHz).
At the same time, Intel Xeon E3-1285L v4 has a lower TDP (65 W vs 95 W).
Both processors match on: core count (4), thread count (8), maximum clock (3.8 GHz), process node (14 nm), maximum memory size (32 GB), 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.
