Intel Pentium Gold 6405U

2C/4T · 15 W

The Intel Pentium Gold 6405U is the Pentium-branded dual-core of Intel's Comet Lake-U family, launched in late 2019 for budget thin and light laptops. It sits above the Celeron 5205U by adding Hyper-Threading for four threads and a higher 2.4 GHz clock, though Turbo Boost and AVX remain reserved for the Core models.

Notes
Covered by Microsoft's Windows 11 24H2 and 25H2 supported-processor lists (Pentium Gold 6000 series); 26H2 keeps the same hardware requirements. Windows 10 and mainstream Linux distributions such as Ubuntu, Fedora and Arch are supported. It lacks AVX, so it does not meet the x86-64-v3 level.
