There has been some excitement in the announcement of Microsoft’s new Ultimate Power Plan. This power plan, for those who haven’t heard about it, is destined for Windows 10 Professional for Workstations. The setting also is present in Windows 10 Professional and Enterprise build 1803, but you have to add it in an administrative cmdline.
powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61
After doing this, it appears in your Power Options:
So, what does it do exactly?
Well, right now, I don’t think it does anything High Performance doesn’t do.
What what?!
Yeah, so here I am running minerd, a CPU hashing program. It’s parked on 4 cores of my AMD Ryzen 2700x.
Now what is the hash rate for each. The same.
So, what gives?
Do a dump of High Performance, and Ultimate. It’s not hard.
Dump:
set power plan to high performance powercfg -query > C:\temp\high.txt change to your power plan to ultimate powercfg -query > C:\temp\ultimate.txt ??? compare profit!
So what’s next?
Uh, nothing? I’m personally staying on Ryzen because it works a ton better than Balanced and saves a smidge of power. For an Intel in a production environment? High. What about Ultimate? Meh for now. Sorry Microsoft.
