Intel Atom серии C3308 vs Intel Atom серии C3558: comparison
Comparison of Intel Atom серии C3308 and Intel Atom серии C3558: key differences and a full specification table.
Key differences
Intel Atom серии C3308 has a lower TDP (9.5 W vs 16 W).
At the same time, Intel Atom серии C3558 has more cores (4 vs 2), more threads (4 vs 2), a higher base clock (2.2 GHz vs 1.6 GHz) and a higher maximum clock (2.2 GHz vs 2.1 GHz).
Both processors match on: process node (14 nm), PCIe version (3).
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.
