Intel Xeon E3-1501L v6 vs Intel Atom x7-E3950: comparison
Comparison of Intel Xeon E3-1501L v6 and Intel Atom x7-E3950: key differences and a full specification table.
Key differences
Intel Xeon E3-1501L v6 has a higher base clock (2.1 GHz vs 1.6 GHz), a higher maximum memory size (64 GB vs 8 GB) and a newer PCIe version (3 vs 2).
At the same time, Intel Atom x7-E3950 has a lower TDP (12 W vs 25 W) and more memory channels (4 vs 2).
Both processors match on: core count (4), thread count (4), process node (14 nm).
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.
