AMD Ryzen 5 7540U vs AMD Ryzen 5 7640HS: Comparison
Ryzen 5 7540U vs Ryzen 5 7640HS p-core boost clock compared
The first real difference is p-core boost clock: Ryzen 5 7540U 4.9 GHz against Ryzen 5 7640HS 5.0 GHz. There is a split on p-core base clock as well, 3.2 GHz on the Ryzen 5 7540U versus 4.3 GHz on the Ryzen 5 7640HS. There is a split on tdp as well, 28 W on the Ryzen 5 7540U versus 35-54W on the Ryzen 5 7640HS. Socket is not the same on both, FP7, FP7r2 on the Ryzen 5 7540U versus FP7, FP7r2, FP8 on the Ryzen 5 7640HS. Pcie lanes runs the same way, 14 on the Ryzen 5 7540U versus 20 on the Ryzen 5 7640HS, another win for Ryzen 5 7640HS. Igpu is not the same on both, AMD Radeon 740M on the Ryzen 5 7540U versus AMD Radeon 760M on the Ryzen 5 7640HS. Base power is not the same on both, 28 W on the Ryzen 5 7540U versus 35 W on the Ryzen 5 7640HS. They differ on max turbo power too, 30 W on the Ryzen 5 7540U versus 54 W on the Ryzen 5 7640HS. There is a split on igpu model as well, AMD Radeon 740M on the Ryzen 5 7540U versus AMD Radeon 760M on the Ryzen 5 7640HS.
Who each one is for
The Ryzen 5 7540U suits mainstream desktop builds and everyday productivity, though it is the wrong buy for extreme overclocking (unless K/X-series) and workstation-class multi-threaded workloads. Buy the Ryzen 5 7640HS 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.
Where the two are identical
The common ground is wider than the gap: total cores, performance cores, efficiency cores, total threads and configurable tdp floor are identical here. They match on 17 further specifications as well.
Frequently asked questions
Do the Ryzen 5 7540U and Ryzen 5 7640HS differ on igpu compute units?
Yes. iGPU Compute Units reads 4 on the Ryzen 5 7540U versus 8 on the Ryzen 5 7640HS.
