Intel Pentium Gold 6500Y vs Intel Pentium Gold 6405U: comparison
Comparison of Intel Pentium Gold 6500Y and Intel Pentium Gold 6405U: key differences and a full specification table.
Key differences
Intel Pentium Gold 6500Y has a lower TDP (5 W vs 15 W) and a newer PCIe version (3 vs 2).
At the same time, Intel Pentium Gold 6405U has a higher base clock (2.4 GHz vs 1.1 GHz), a higher maximum memory size (64 GB vs 16 GB) and a higher maximum integrated graphics clock (950 MHz vs 900 MHz).
Both processors match on: core count (2), thread count (4), process node (14 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.
