HP Spectre x360 16 inch 2-in-1 Laptop PC 16-f0000 (39R25AV)
Microsoft Windows 11

So the Spectre 16's 11390H energy profile is very conservative. It'll always throttle performance by a good chunk if you don't disable most power limits in Throttlestop, but I've found a limit that I can't seem to overcome.

 

With Throttlestop I can set my power limits to 65 watts for the CPU, which it can achieve these watts during stress tests and certain games, but immediately after it goes over the 40 watt range for more than 20 seconds, it goes back from 65w to 40w and show in Throttlestop it's power limit throttling with a red "PL1"icon. Even if I have both Long Power PL1 and Short Power PL2 set to 65 in Throttlestop, this still keeps on happening. And it's not even temperature related, cuz you can set PL1 to even 42w but after 20 or so seconds it drops back down to 40w until the program you're using gets less CPU demanding. This severly limits performance for any long CPU intensive task especially in games which are being CPU bottlenecked like people who use external GPUs. I would like a way to overcome this PL1 limit, time limit PL1, whatever it's called, to be able to take advantage of the full capacity of the 11390H. Heck, we're being limited to a mere 4 core CPU in 2021-2022, might as well let the user be able to manually control this in Throttlestop for those who need it. This has a locked PROCHOT of 95 degrees C, so it'll never overheat the CPU anyways. A BIOS update that fixes this would be greatly appreciated, or I might just have to end up returning this Spectre 16 for a Dell XPS 9510 which offers much better performance metrics.
