Intel Atom серии E640 vs Intel Atom серии E660: comparison
Comparison of Intel Atom серии E640 and Intel Atom серии E660: key differences and a full specification table.
Key differences
Intel Atom серии E660 has a higher base clock (1.3 GHz vs 1 GHz).
Both processors match on: core count (1), thread count (2), TDP (3.6 W), process node (45 nm), maximum memory size (2 GB), memory channels (1), PCIe version (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.
