Desktop 5600X vs Notebook 5800H

I would hazard a guess that the 5600X will be faster, at least in single-threaded IPC and workloads.

5600X has more L3 cache (32GB versus 16GB for 5800H), faster base frequency, faster turbo clock and XFR 2 support.

Also the 5600X has PCIe Gen 4 support (the 5800H has Gen 3) so it would have faster disk I/O with the properly paired m.2 SSD.

For some multi-threaded workloads the 5800H might be faster simply due to the two extra CPU cores. For this reason, I still do Handbrake encodes on my 8-core 3700X rather than another system with a 6-core 5600X.

So, in most cases 5600X will be faster

The desktop can maintain certain speeds due to limitless cooling that any mobile just doesnt have.

It depends.

Each person's usage case is different which is why CPU manufacturers offer a wide range of models with different capabilities and performance.

I know that the mundane daily stuff that I do (office productivity, web browsing, e-mail, watching videos, etc.) generally does not heavily exploit multi-threaded performance. Some things like video editing, video encoding, etc. do but I rarely perform those tasks.

Some people might be compiling lots of code very frequently using compilers that do take advantage of multiple threads. I don't do that. Do you?

Most consumers aren't doing just one thing on their PCs, they do a variety of things, some of which benefit from more CPU cores, others which do not.

For sure prolonged workloads can be maintained better by a desktop system generally due to a more robust cooling solution.

Plus there are other considerations such as acoustics. I can run a Handbrake encode on my Acer Swift 3 notebook but the fan is quite whiny and unpleasant. By contrast the 140mm AIO radiator fan in my NZXT H1 case never gets terribly loud. I'm not even using the stock fan that came with the case, I replaced it with a Noctua NF-A14 industrialPPC-2000 PWM fan; the fan curve I've set tops out at 1500 rpm (75% of the 2000 rpm max speed).

Which one would you rather listen to for 45 minutes?

Superior single-thread IPC performance is important for some things and less for others. If CPU A is 17% faster in single-thread IPC performance than CPU B, does it matter while I'm using Notepad or Excel? No, if it takes 0.83 second to open a spreadsheet on CPU A and 1 second on CPU B, I'm not going to notice. It might be more noticeable while gaming on certain titles. For CPU bound games, 117 fps versus 100 fps might actually be meaningful.

5800H in a laptop chassis and 5600X in a desktop chassis. Both are well-cooled

What model laptop. Some laptops cool better than others.
The 5800h can usually hit around 3.8-4.1ghz all core at 100%.
 
One major issue with notebook computers is that they might have exceptional burst performance but will thermal throttle during extended workloads.

If a mobile CPU can max out at ____ boost clock but only hold that for five minutes before it starts to thermal throttle, the peak figure isn't a good measurement of real world performance. This is why short duration test suites like Geekbench are frequently dismissed by more knowledgeable readers.

By contrast, a properly cooled desktop CPU can maintain sustained peak performance for hours and hours.

The 5600x can handle 4.5-4.6ghz at 100% all day long, the 5800h, 3.8-4.1ghz.
 
Yeah, CPU manufacturers only quote boost clocks. They never say how long that peak can be maintained.

That's one of the fundamental problems with the original inquiry and illuminates a major shortcoming with benchmarks in general.

Just trying to understand the concept

Its different environment. The laptop 5800h goes into a laptop that can be moved around, the 5600x will be in a desktop that its harder to move around but it can be upgraded in the future, run cooler and quieter. The 5600x is usually faster overall but both have its pros and cons.
You will usually pay a higher price on the 5800h for the performance it gives.

Tell us more on what programs you want to use, budget, if you live in a tight space or you travel, etc.
 
There are too many other unknown variables that matter too. For example, how much RAM is installed? What type drives? Motherboard bus speeds? Graphics solutions? Programs loading with Windows? Yadda yadda.

To me, it is not a fair comparison. It is like comparing a Toyota Camry to a Chevy Silverado pickup truck. One is a car and the other is a truck. They both can carry people and cargo, but neither can do all of the same tasks as the other. They are not designed for the same purpose.

The car can certainly haul 4 people and a trunk full of luggage down the highway faster than the truck. But the truck can haul 4 people, their luggage and pull a 8,000lb trailer down the highway faster than the car.
 
A 5600x will beat a 5800H in almost all scenarios.

At bone stock the 5600x is faster -- With few multithreaded apps being a tiny bit faster on the 5800H. But:

- Desktop DDR4 3800 is cheap and plentiful vs laptop DDR4... and you can tighten ram timings. (Which will increase in IF frequency, and Zen 3 scales like crazy with fast ram - see SOTR benchmark thread - these guys go from 5% lows of 120FPS stock to 170 with just ram and PBO), also you can run 4x dual rank for performance on top of that.
- Higher wattage part, with decent thermals and a consistent sustained load -- will not throttle due to heat (unless you really cheap out on the cooling)

TLDR, as soon as you touch PBO or tune the ram timings the 5600x will gorilla smash the 5800H. As it should - it's a desktop class chip with loads more power budget.

Notebookcheck geomean has the 5600x faster than even the 5900HX (at stock) - add to it that it's very easy to squeeze a lot more performance out of the desktop variant and they are just not even in the same league.
