Verdict

The AMD Ryzen 5 8645HS is an upper mid-range mobile processor from the Hawk Point family, featuring 6 Zen 4 cores and 12 threads with a base clock of 4.3 GHz and a boost up to 5.0 GHz. Built on TSMC's 4nm FinFET process, it includes 16 MB of L3 cache, a configurable TDP between 35W and 54W, and an integrated Radeon 760M GPU with 8 cores running at 2600 MHz. Its main strengths include strong single-core performance, native support for USB4 and PCIe 4.0, and an integrated NPU (Ryzen AI) capable of up to 16 TOPS for AI-accelerated tasks. However, it is largely a rebrand of the previous 7640HS with only minor AI performance improvements, lacks an unlocked multiplier for overclocking, and can exhibit high operating temperatures up to 100°C in some laptop thermal designs.
