Intel Core M-5Y51 vs Intel Core M-5Y71: comparison
Comparison of Intel Core M-5Y51 and Intel Core M-5Y71: key differences and a full specification table.
Key differences
Intel Core M-5Y71 has a higher base clock (1.2 GHz vs 1.1 GHz) and a higher maximum clock (2.9 GHz vs 2.6 GHz).
Both processors match on: core count (2), thread count (4), TDP (4.5 W), process node (14 nm), maximum memory size (16 GB), memory channels (2), PCIe version (2), maximum integrated graphics clock (900 MHz).
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.
