AMD Ryzen 5 6600H vs AMD Ryzen 5 6600U: Comparison
Ryzen 5 6600H vs Ryzen 5 6600U: the p-core base clock difference
The first real difference is p-core base clock: Ryzen 5 6600H 3.3 GHz against Ryzen 5 6600U 2.9 GHz. They differ on configurable tdp floor too, 35 W on the Ryzen 5 6600H versus 15 W on the Ryzen 5 6600U. They differ on base power too, 45 W on the Ryzen 5 6600H versus 15 W on the Ryzen 5 6600U.
Which should you buy, Ryzen 5 6600H or Ryzen 5 6600U?
Buy the Ryzen 5 6600H 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 5 6600U is the one to take 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 p-core boost clock are identical here. They match on 23 further specifications as well.
Frequently asked questions
Is the L3 Cache the same on the Ryzen 5 6600H and Ryzen 5 6600U?
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 6600H if you want the higher L2 cache (3 MB vs 3 MB), the higher L3 cache (16 MB vs 16 MB) and the higher memory channels (2 vs 2).
Choose 6600U if you already have it on hand or find it at a lower price.
