Intel Xeon E3-1105C v2 vs Intel Atom серии C2738: comparison
Comparison of Intel Xeon E3-1105C v2 and Intel Atom серии C2738: key differences and a full specification table.
Key differences
Intel Xeon E3-1105C v2 has a newer PCIe version (3 vs 2).
At the same time, Intel Atom серии C2738 has more cores (8 vs 4), a higher base clock (2.4 GHz vs 1.8 GHz), a lower TDP (20 W vs 25 W) and a higher maximum memory size (64 GB vs 32 GB).
Both processors match on: thread count (8), process node (22 nm), memory channels (2).
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.
