AMD Ryzen 5 7540U vs AMD Ryzen 5 7640U: Comparison
What is the difference between Ryzen 5 7540U and Ryzen 5 7640U?
They are built to different briefs, and p-core base clock shows it, Ryzen 5 7540U 3.2 GHz against Ryzen 5 7640U 3.5 GHz. Socket is not the same on both, FP7, FP7r2 on the Ryzen 5 7540U versus FP7, FP7r2, FP8 on the Ryzen 5 7640U. They differ on form factor too, Laptops, Desktops on the Ryzen 5 7540U versus Laptop on the Ryzen 5 7640U. There is a split on igpu as well, AMD Radeon 740M on the Ryzen 5 7540U versus AMD Radeon 760M on the Ryzen 5 7640U. They differ on igpu model too, AMD Radeon 740M on the Ryzen 5 7540U versus AMD Radeon 760M on the Ryzen 5 7640U. There is a split on igpu compute units as well, 4 on the Ryzen 5 7540U versus 8 on the Ryzen 5 7640U.
Which should you buy, Ryzen 5 7540U or Ryzen 5 7640U?
The Ryzen 5 7540U is the one to take for mainstream desktop builds and everyday productivity, though it is not built for extreme overclocking (unless K/X-series) and workstation-class multi-threaded workloads. The Ryzen 5 7640U suits midrange thin-and-light laptops and office work, browsing and video calls, though it is not the pick for modern games at high settings without a dedicated GPU and copilot+ PC AI features, which need a 40+ TOPS NPU. It is not the one for heavy video rendering or 3D work, where 8-core chips finish much sooner.
Where the two are identical
Where they agree, they agree completely, total cores, performance cores, efficiency cores, total threads and p-core boost clock included, so the decision does not turn on any of those. They match on 20 further specifications as well.
Frequently asked questions
Is the TDP the same on the Ryzen 5 7540U and Ryzen 5 7640U?
It is. Both are listed at 28 W, so it is not a reason to pick one over the other.

Which one should you pick?
Choose 7540U if you want the higher L2 cache (6 MB vs 6 MB), the higher L3 cache (16 MB vs 16 MB) and the higher memory channels (2 vs 2).
Choose 7640U if you already have it on hand or find it at a lower price.
