Windows 10 Ultimate Performance mode

Hi,

I enabled the Ultimate Performance mode on my Windows 10 laptop (21H1 update) and ran Cinebench R23 to check the performance of the CPU in this mode. However, I was left quite disappointed.
The Multi-core and Single-core scores I got was exactly the same that I had got when I had run with High Performance mode enabled. One thing I observed was the all CPU cores was being run at its highest frequency (3.4 GHz) even when the laptop was idling in Ultimate mode.

Can anyone explain how the Ultimate mode works and in which scenarios it might prove handy?

Regards,
Rinjo

Thanks for the quick response Paul. I will go through the thread you have directed me to.

It is of no use to you, particularly as regards Laptops.

This is just a repeat of what I have said before. The basics.

A laptop is limited as to the cooling solution of the manufacturer, and obviously the restricted space.

1. A better CPU performance means increased power consumption. A Laptop will just overheat and the thermal protection will then click in.

2. High temperatures permanently damage CPUs when used beyond their rated 90°C or whatever it is for a particular CPU.

3. CPUs are designed to turbo up CPU frequency and thus performance when required.

This limits anything that can be done with a Power plan as regards computing performance. As you have found out.

I expect to fully take advantage of Ultimate Performance Mode you would need to be running a CPU bound application using multiple cores at full CPU frequency, and be able to maintain that for extended periods of time. You need good cooling to do that. Few laptops could tolerate that kind of workload without throttling back to avoid overheating.

By default this mode is supported only on Windows 10 Professional Workstation. This OS is designed to support high end hardware that otherwise would require a server OS. The OS supports 4 physical CPU packages, 256 cores, and 6 TB of RAM. It is designed for a demanding professional environment where hardware cost isn't a serious concern. I don't know if such hardware actually exists at this time but there are people who would by it if it was available. You can assume such hardware will have excellent cooling and would be able to run demanding software for many hours or days without overheating.

This is the environment the setting was designed for.
Laptops must make many compromises with performance in order to keep power consumption and heat within acceptable limits.
