Intel Atom серии Z615 vs Intel Atom серии N455: comparison
Comparison of Intel Atom серии Z615 and Intel Atom серии N455: key differences and a full specification table.
Key differences
Intel Atom серии Z615 has a lower TDP (2.2 W vs 6.5 W).
At the same time, Intel Atom серии N455 has a higher base clock (1.66 GHz vs 1.6 GHz).
Both processors match on: core count (1), thread count (2), process node (45 nm), maximum memory size (2 GB), memory channels (1).
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.
