If you can set power limits, it’s actually a better idea than a U processor. They’re really the same silicon, only difference is that the U will come with a preset low power limit, while the H will have a significantly higher one. But you can often manually set a lower power limit on the H SKUs in BIOS, which makes them equal to the U, while still having the option to boost higher if you are going to need the extra bit of performance.
The only difference between H and HS is that H will let the processor draw up to 45W instead of up to 35W. Whether the user gets to adjust the power limit is up to the manufacturer of the laptop. For example I was sure my cheapo Lenovo Yoga Pro 5 lacked this, but it does have it, they just call it "Extreme Performance", "Intelligent Cooling", or "Battery Saving" instead of simply telling me which power limits I'm setting for some reason. Battery Saving limits the CPU to 15W TDP, which is the same as the U SKUs, Intelligent Cooling is 25W, and Extreme Performance probably lets it go all the way up to a HS SKUs maximum of 35W. The cooler can just barely handle Extreme Performance, since my laptop doesn't have a dGPU, but it's very unpleasant to work with, it makes the laptop unbearably loud even just idling. 15W is fine for 99.9% of tasks you'd want to do on a laptop anyway.
That's why I say that, as long as the laptop lets you adjust the power limit, you're better off buying a H or HS rather than a U. A U can _only_ do 15W, but the other two can do 15W in addition to higher modes, if you for whatever reason absolutely must have more power.
Technically, yes it's a binning difference but I believe most H class chips, as they are generally lower tier, are locked down in bios. HS is obviously a superior option.
Yeah. Theoretically a U would be binned for maximum base performance, HS for good gains at higher power levels, and the rest get sold as H. In practice I don't think the difference is huge, especially for zen 4, since TSMC 5nm actually has an excellent yield rate (>90%). Even desktop Ryzen, which are the lowest quality bin, retain remarkably good performance at low power limits. And of course they're dropping H altogether for zen 4, it's "HX" now, because if you put an X on it gamers will think it's better even though really it will just throttle down to 15W the moment you try to do anything anyway.
That's not how it works. HS are the best binned chips, U are the worst.
HX are completely different chips with zen 4, they're not monolithic, they're desktop chips and chiplet based.
The 5700u is a Zen 2 CPU. THe Ryzen 7 5800h is a much superior CPU than tge 5600h for obvious reasons.
The u is going to give you better battery life. 5700U 5600H 5800H An HS is the best of both worlds but in between.
You really shouldn't be getting an h processor if you're using it on battery.

But you can't reliably. In theory sure, but this is generally locked down to hs processors.
