AMD Ryzen 7 6800U vs AMD Ryzen 7 7840HS: Comparison
Ryzen 7 6800U vs Ryzen 7 7840HS p-core boost clock compared
The first real difference is p-core boost clock: Ryzen 7 6800U 4.7 GHz against Ryzen 7 7840HS 5.1 GHz. P-core base clock is not the same on both, 2.7 GHz on the Ryzen 7 6800U versus 3.8 GHz on the Ryzen 7 7840HS. Ryzen 7 7840HS also leads on l2 cache, 4 MB on the Ryzen 7 6800U versus 8 MB on the Ryzen 7 7840HS. They differ on configurable tdp floor too, 15 W on the Ryzen 7 6800U versus 35 W on the Ryzen 7 7840HS. Socket is not the same on both, FP7 on the Ryzen 7 6800U versus FP7, FP7r2, FP8 on the Ryzen 7 7840HS. They differ on product line too, Ryzen on the Ryzen 7 6800U versus Ryzen 7 on the Ryzen 7 7840HS. They differ on form factor too, Laptops, Desktops on the Ryzen 7 6800U versus Laptop on the Ryzen 7 7840HS. There is a split on release year as well, 2022 on the Ryzen 7 6800U versus 2023 on the Ryzen 7 7840HS. Igpu is not the same on both, AMD Radeon 680M on the Ryzen 7 6800U versus AMD Radeon 780M on the Ryzen 7 7840HS.
Who each one is for
The Ryzen 7 6800U is the one to take for 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. The Ryzen 7 7840HS suits 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
Everything else lines up. Total cores, performance cores, efficiency cores, total threads and l3 cache read the same on both, so those are not worth weighing. They match on 8 further specifications as well.
Frequently asked questions
Do the Ryzen 7 6800U and Ryzen 7 7840HS differ on microarchitecture?
Yes. Microarchitecture reads Zen 3+ on the Ryzen 7 6800U versus Zen 4 on the Ryzen 7 7840HS.
Is the Integrated Graphics the same on the Ryzen 7 6800U and Ryzen 7 7840HS?
It is. Both are listed at Yes, so it is not a reason to pick one over the other.
