Intel Xeon E3-1220L v2 vs Intel Atom серии S1240: comparison
Comparison of Intel Xeon E3-1220L v2 and Intel Atom серии S1240: key differences and a full specification table.
Key differences
Intel Xeon E3-1220L v2 has a higher base clock (2.3 GHz vs 1.6 GHz), a finer process node (22 nm vs 32 nm), a higher maximum memory size (32.23 GB vs 8 GB) and more memory channels (2 vs 1).
At the same time, Intel Atom серии S1240 has a lower TDP (6.1 W vs 17 W).
Both processors match on: core count (2), thread count (4).
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.
