Intel Core i3-3115C vs Intel Atom серии C2758: comparison
Comparison of Intel Core i3-3115C and Intel Atom серии C2758: key differences and a full specification table.
Key differences
Intel Core i3-3115C has a higher base clock (2.5 GHz vs 2.4 GHz) and a newer PCIe version (3 vs 2).
At the same time, Intel Atom серии C2758 has more cores (8 vs 2), more threads (8 vs 4), a lower TDP (20 W vs 25 W) and a higher maximum memory size (64 GB vs 32 GB).
Both processors match on: 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.
