Verdict

The AMD Ryzen 5 8640HS is a mid-range mobile processor from the 'Hawk Point' family, built on a 4nm TSMC process with the Zen 4 architecture. It features 6 cores and 12 threads with a base clock of 3.5 GHz and a max boost clock of 4.9 GHz, supported by 16 MB of L3 cache and a default TDP of 28W. Key pros include the integrated Radeon 760M graphics, high energy efficiency, and a dedicated NPU providing up to 16 TOPS for AI-accelerated tasks. However, notable cons include its locked multiplier which prevents overclocking, and performance that may be limited in demanding games without a dedicated GPU.

What customers dislike about AMD Ryzen 5 8640HS?

  • Not intended for high-end AAA gaming; modern titles may require very low resolutions and settings
  • Integrated graphics (Radeon 760M) are significantly weaker than the 780M found in Ryzen 7 models
  • The processor is soldered to the motherboard, meaning it cannot be upgraded by the user
  • Performance can vary significantly depending on the laptop manufacturer's cooling and power limits
  • Lack of overclocking support as the multiplier is locked
  • Essentially a rebadged version of the previous generation (Ryzen 5 7640U) with minor AI clock speed bumps
