Intel Pentium D1517 vs Intel Xeon E3-1265L v4: comparison
Comparison of Intel Pentium D1517 and Intel Xeon E3-1265L v4: key differences and a full specification table.
Key differences
Intel Pentium D1517 has a lower TDP (25 W vs 35 W), a finer process node (7 nm vs 14 nm) and a higher maximum memory size (128 GB vs 32 GB).
At the same time, Intel Xeon E3-1265L v4 has a higher base clock (2.3 GHz vs 1.6 GHz) and a higher maximum clock (3.3 GHz vs 2.2 GHz).
Both processors match on: core count (4), thread count (8), 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.
