AMD Ryzen 7 5800H vs AMD Ryzen 7 5800U: Comparison
Ryzen 7 5800H vs Ryzen 7 5800U: the p-core base clock difference
They are built to different briefs, and p-core base clock shows it, Ryzen 7 5800H 3.2 GHz against Ryzen 7 5800U 1.9 GHz. They differ on tdp too, 45 W on the Ryzen 7 5800H versus 15 W on the Ryzen 7 5800U. There is a split on base power as well, 45 W on the Ryzen 7 5800H versus 15 W on the Ryzen 7 5800U. Memory type is not the same on both, DDR4-3200, LPDDR4-4266 on the Ryzen 7 5800H versus DDR4, LPDDR4 on the Ryzen 7 5800U.
Who each one is for
Take the Ryzen 7 5800H for high-performance gaming laptops wanting genuine Zen 3 architecture with strong single- and multi-thread performance. It is not the one for buyers on the tightest budget, the Ryzen 5 5600H offers similar core architecture at a lower price with reduced core count. Take the Ryzen 7 5800U for ultraportable laptops wanting genuine Zen 3 architecture with strong single- and multi-thread performance at 15W. It is the wrong buy for buyers on a tighter budget who don't need Zen 3 specifically, the Zen 2-based Ryzen 7 5700U offers similar core count for less.
Where the two are identical
Everything else lines up. Total cores, performance cores, efficiency cores, total threads and p-core boost clock read the same on both, so those are not worth weighing. They match on 20 further specifications as well.
Frequently asked questions
Is the L3 Cache the same on the Ryzen 7 5800H and Ryzen 7 5800U?
It is. Both are listed at 16 MB, so it is not a reason to pick one over the other.

Which one should you pick?
Choose 5800H 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 5800U if you already have it on hand or find it at a lower price.
