What distinguishes the high-performance power mode from the ultimate performance mode in Windows 11?
I experimented with various power plans in Windows, but I'm still figuring out the distinctions between them.
Unfortunately, it seems MS might not be aware of this. For details on which power plan to use in Windows 11 and when, you can check the article below:
Which Power Plan should you use in Windows 11 and when?
Windows 11/10 offers three main power plans: High Performance, Balanced, and Power saver. Each has its advantages and disadvantages.

I can't really say I've ever encountered that on a standard Windows setup.
It might be a special power plan set up by someone else.
Let me know if you'd like more details.
You can turn it on by choosing the choice for unrestricted extra plans. I'm just curious about its function.
Generally, on Ultimate settings, none of your connected devices enter sleep mode. This applies to CPU/GPU, USB, and SSDs. It can lead to increased temperatures while the PC is idle and may consume more CPU cycles. Regarding long-term effects, I’m uncertain if this would cause quicker wear in components, but since they’re always active, it could be a possibility.
I don't bother running them. Do you need your PC to stay warm constantly? I recall using a Samsung SSD with performance optimisation enabled, running the PC in High performance mode while also applying an OC to the CPU. The CPU doesn't have to run at full speed just for a desktop setup. I stopped using them soon because it was uncomfortable in the summer.
The three standard configurations:
Power saver: The majority of peripheral power-saving features are activated or configured for maximum aggressiveness. CPU core parking remains active.
Balanced: Most peripheral power-saving settings are either turned on or set to a moderate level. CPU core parking is inactive.
High Power: The majority of peripheral power-saving options are turned off.
It's worth mentioning that there are likely numerous hidden settings when adjusting advanced power options. For instance
powercfg -attributes sub_processor perfboostmode -attrib_hide
displays the choice for CPU boosting while
powercfg -attributes sub_processor 0cc5b647-c1df-4637-891a-dec35c318583 -attrib_hide
reveals the core parking option. Interestingly, the CPU boosting setting is consistently "Aggressive" across all three modes.
Additionally, I've observed that even in High Power mode, the CPU's power management still activates by lowering clock speeds and transitioning to other C-states. It might be possible to disable this feature, but it seems to be restricted to BIOS settings.
Similarly, video cards (particularly NVIDIA models, though I don't have an AMD unit to verify) will still reduce clock speeds even when you request "maximum performance." PCIe Link power management only impacts the situation if the PCIe bus is permitted to enter a lower-power state.
Overall, the main variation when selecting higher settings than balanced appears to be more consistent performance. However, as long as a high-performance component is running, the system is unlikely to enter a low-power mode. For steady performance, you'll need to set the clock speed accordingly.
For Zen 3 it's not necessary. Windows Balanced allows the CPU to function as designed. This seems due to improvements in the AGESA software over time. However, every chipset driver I've updated still includes a Ryzen balanced option. Don't worry!
🤣
Still needed for Zen 3xxx/2xxx as far as I know.
