I recently purchased a new laptop with Windows 11 and an i9 CPU. My first impression was less than wow. In fact, it seemed slower than the laptop it replaced. The punch line is, you pay for a lot of extra cores that are not any faster than an i7 or i5. Maybe even an i3. At any rate, I recently started looking at CPU usage and discovered a mode I hadn’t noticed before: PARKED CPU. Yep, apparently, Windows puts unused CPUs in parked mode to save energy. I noticed several times that all but one of my CPUs was parked. Only occasionally, I may see 3 CPUs actually working. Yes, my workflow is mostly sitting in a programmer’s IDE like VS Code or Visual Studio. Then I may compile some code now and then. I may open a browser or read my emails. That’s about it. So I paid double what I needed to, just so I could have an i9 badge on my laptop. I feel ashamed.

Some of you may want to know what computer I bought: it’s an ASUS Q540VJ. I way over provisioned it with RAM and SSD. I like the hardware, don’t mis-understand me. I just way over over bought. The Q530 would have been more appropriate, in my case.

Go to the Windows power settings and adjust your max CPU performance and clock frequency to 100%. Laptops with the power saving or even balanced power plans reduce the max CPU clock to a fraction of their proper performance levels. You may have to create a new power plan to use the high performance when docked/plugged in so you don't eat you battery immediately. I had to do this on a computer in my studio that was having audio drop-out issues with my audio interface. The power plan reduced the CPU performance enough to cause audio latency that exceeded the audio interface's specs. You may be able to un-park more CPUs by doing this.

How much RAM? Load Debian and Virtualbox on it and you can run Win Servers to test with. You don't really need to know linux inside and out if you are mostly developing .NET. Just set up an internal virtualbox network between them. Do not use that Hyper V garbage.

Is this a Winblows 11 problem that can be worked around? Would a Linux OS make a difference?

No doubt, Windows adds a considerable amount of CPU overhead, but based on how I understand multi-core processors and operating systems, the scenario I talked about will be OS agnostic. Linux will offer better performance, mostly, but won't utilize multiple cores any differently. Thus, my conclusion won't change: too many cores only works faster when your application actually uses multiple cores. Video rendering is one workflow that does work well. Occasionally, I make videos. This is where the i9 excels. I didn't bring that up, because it's an edge case for me. However, if you find yourself opening multiple applications and windows, an i9 will help keep your workflow faster. Personally, I try to minimize the number of concurrently open applications.

I noticed this a while ago. The more expensive CPUs have more processor cores that are individually slower. The cheaper CPUs have a small number of faster cores.

If you spend all of your time compiling, encoding videos, or playing games then spend the extra money for more cores. Otherwise, you are paying more to make most of what you do slower.

I like to buy for the fringe case because when you really need it there's no substitute. I'd rather have one that does it all well vs two that do individual tasks great but combine poorly. Imo.

I went from a 2012 dual core i5 to a 12th gen i9 and the difference is massive. I do a lot of music production so maybe I’m utilizing the cores more, but it was well worth the upgrade in my case.
