What it is
Our main score for this model, 1–10. It combines specs, expert reviews, best-of lists and owners.
How we count it
Parts: Technical score 40%, Reviews score 25%, List score 25%, Sentiment score 10%
Marks: Each part gets a mark out of 10. For reviews, lists and owners, a typical model in this category gets about 8 and the best one gets 10.
No data yet: A part with no data shows "?". It counts as the mark of a weaker model in this category (4 in 5 models with data score higher). This way, models with reviews, lists and owners usually come out ahead.

What it is
Average grade from independent test sites, magazines and video reviewers, 1–10.
How we count it
Grades: Each review's own score is converted to 1–10; without one, we grade the review ourselves. Big test sites count more, short reviews half as much as full tests. A video review counts half.
Score: The average grade is 80% of the review mark; the number of reviews is the other 20% (1 review = 5, the typical number in this category = 8, the most-reviewed model = 10).
Enough data: With few reviews, the average grade is pulled toward the typical grade of this category. No reviews yet: 7.2 for now.

Third-party reviews

What customers like about AMD Ryzen 5 8640H

  • Strong power efficiency leading to 'all-day' battery life for typical office and school work
  • Excellent multitasking performance for web browsing (Chrome), MS Office, and video calls
  • Integrated Radeon 760M graphics perform significantly better than standard Intel integrated solutions
  • Stays relatively cool during normal productivity tasks
  • Integrated AI NPU provides a noticeable boost for generative AI and productivity apps

What customers don't like about AMD Ryzen 5 8640H

  • Limited for high-end gaming; struggles with high graphics settings in demanding titles
  • Integrated graphics (Radeon 760M) are outperformed by competitors like the Intel Arc Xe 8 in gaming-specific benchmarks
  • Locked multiplier prevents manual overclocking for performance enthusiasts
  • Performance can be heavily capped by the specific laptop's cooling solution and power limits
  • Not intended for heavy 3D rendering or professional video editing software

Verdict

The AMD Ryzen 5 8640H is a mid-range mobile processor from the Hawk Point family, featuring 6 Zen 4 cores and 12 threads with a 3.5 GHz base and 4.9 GHz boost clock. Built on a highly efficient TSMC 4nm process, it includes 16 MB of L3 cache, a default TDP of 28W, and integrated Radeon 760M graphics that support light gaming and up to four displays. Its standout features are the dedicated Ryzen AI NPU delivering up to 16 TOPS for AI-accelerated tasks and support for modern connectivity like USB4 and PCIe 4.0. While it offers excellent power efficiency and single-core responsiveness, it is not overclockable and its integrated graphics may struggle with demanding AAA titles at high settings.
