Intel Atom серии C2558 vs Intel Atom серии C2738: comparison
Comparison of Intel Atom серии C2558 and Intel Atom серии C2738: key differences and a full specification table.
Key differences
Intel Atom серии C2558 has a lower TDP (15 W vs 20 W).
At the same time, Intel Atom серии C2738 has more cores (8 vs 4) and more threads (8 vs 4).
Both processors match on: base clock (2.4 GHz), process node (22 nm), maximum memory size (64 GB), memory channels (2), PCIe version (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.
