Verdict

The AMD Ryzen 5 Pro 8640U is a high-efficiency mobile processor from the Hawk Point family, built on a 4nm TSMC process with Zen 4 architecture. It features 6 cores and 12 threads with a 3.5 GHz base clock and a max boost up to 4.9 GHz, supported by 16 MB of L3 cache and a default TDP of 28W (configurable from 15-30W). Its primary strengths include an integrated Radeon 760M GPU for capable entry-level gaming and a dedicated Ryzen AI NPU delivering up to 16 TOPS for accelerated local AI workloads. As a 'Pro' model, it offers enhanced enterprise-grade security and manageability suites. Main drawbacks include a locked multiplier that prevents overclocking and the fact that it is a rebadged version of the 7640U with only minor NPU improvements.
