AMD Ryzen 9 4900H vs AMD Ryzen 9 5980HX: Comparison
Ryzen 9 4900H vs Ryzen 9 5980HX: the l3 cache difference
On l3 cache the spread is 50%, Ryzen 9 4900H 8 MB against Ryzen 9 5980HX 16 MB, so Ryzen 9 5980HX takes it. There is a split on p-core boost clock as well, 4.4 GHz on the Ryzen 9 4900H versus 4.8 GHz on the Ryzen 9 5980HX. There is a split on release year as well, 2020 on the Ryzen 9 4900H versus 2021 on the Ryzen 9 5980HX. Microarchitecture is not the same on both, Zen 2, Ryzen 4000 Series "Renoir" on the Ryzen 9 4900H versus Zen 3, Ryzen 5000 Series "Cezanne" on the Ryzen 9 5980HX. Memory type is not the same on both, DDR4-3200, LPDDR4-4266 on the Ryzen 9 4900H versus DDR4, LPDDR4 on the Ryzen 9 5980HX.
Ryzen 9 4900H vs Ryzen 9 5980HX: which one fits your build
Take the Ryzen 9 4900H for gaming laptops of the Ryzen 4000 generation wanting strong 8-core, single-thread-focused performance. Avoid it for buyers specifically wanting maximum multi-threaded ceiling from hyperthreading, the SMT-equipped Ryzen 9 4900HS delivers stronger results in heavily-threaded workloads. Take the Ryzen 9 5980HX for desktop-replacement gaming laptops wanting AMD's absolute strongest mobile Zen 3 performance without HS-tier power constraints. It is not the one for buyers wanting a thin, portable gaming laptop, the HS-tier chips are specifically built for thinner chassis designs.
Where the two are identical
Everything else lines up. Total cores, performance cores, efficiency cores, total threads and p-core base clock read the same on both, so those are not worth weighing. They match on 9 further specifications as well.
Frequently asked questions
Is the TDP the same on the Ryzen 9 4900H and Ryzen 9 5980HX?
It is. Both are listed at 45 W, so it is not a reason to pick one over the other.
