AMD Ryzen 9 5900HX vs AMD Ryzen 9 6900HS: Comparison
What is the difference between Ryzen 9 5900HX and Ryzen 9 6900HS?
The first real difference is p-core boost clock: Ryzen 9 5900HX 4.6 GHz against Ryzen 9 6900HS 4.9 GHz. There is a split on release year as well, 2021 on the Ryzen 9 5900HX versus 2022 on the Ryzen 9 6900HS. They differ on igpu too, AMD Radeon Graphics on the Ryzen 9 5900HX versus AMD Radeon 680M on the Ryzen 9 6900HS. They differ on microarchitecture too, Zen 3, Ryzen 5000 Series "Cezanne" on the Ryzen 9 5900HX versus Zen 3+ on the Ryzen 9 6900HS. Unlocked multiplier is not the same on both, Yes on the Ryzen 9 5900HX versus No on the Ryzen 9 6900HS. Base power is not the same on both, 45 W on the Ryzen 9 5900HX versus 35 W on the Ryzen 9 6900HS.
Who each one is for
Take the Ryzen 9 5900HX for desktop-replacement gaming laptops wanting genuinely top-tier AMD mobile Zen 3 performance. Avoid it for buyers wanting the absolute highest clocks in AMD's HX lineup, the 5980HX offers a modest additional edge at the same core count. The Ryzen 9 6900HS 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.
What Ryzen 9 5900HX and Ryzen 9 6900HS have in common
Where they agree, they agree completely, total cores, performance cores, efficiency cores, total threads and p-core base clock included, so the decision does not turn on any of those. They match on 11 further specifications as well.
Frequently asked questions
Do the Ryzen 9 5900HX and Ryzen 9 6900HS differ on socket?
Yes. Socket reads FP6 on the Ryzen 9 5900HX versus BGA on the Ryzen 9 6900HS.
Is the Configurable TDP Floor the same on the Ryzen 9 5900HX and Ryzen 9 6900HS?
It is. Both are listed at 35 W, so it is not a reason to pick one over the other.

Which one should you pick?
Choose 5900HX if you want the higher L2 cache (4 MB vs 4 MB), the higher L3 cache (16 MB vs 16 MB) and the higher memory channels (2 vs 2).
Choose 6900HS if you already have it on hand or find it at a lower price.
