Sep 14, 2020 at 21:43 comment added n1000 @AndrewCassidy OK. This is odd indeed. MacBooks do throttle heavily if not enough power is available or battery is very low. It would be good to have more data on your issue. What was the load when throttling occured? Can you install the latest Power Gadget, e.g. using homebrew and update the screenshot?
Sep 14, 2020 at 21:30 comment added Andrew Cassidy And to update. It does this randomly all the time when I'm trying to use my computer (with CPU use spikes up to 50%) and just creates a laggy experience on my end.

Sep 14, 2020 at 18:57 comment added n1000 @AndrewCassidy In your screenshot the CPU is far from busy with a load of 35% ;-) You would see hardly any to no performance gains and increased battery drain if the clock speed would remain always at the maximum. SpeedStep is optimized to very rapidly change the clock depending on the current load situation. Some Windows PCs allow to tweak this and I wouldn't be surprised if macOS also has different settings depending on whether the Macbook is connected to power or not. There may be a way, but I wouldn't recommend it at all: apple.stackexchange.com/q/116193/45492
Sep 14, 2020 at 18:39 comment added Andrew Cassidy My CPU isn't idle though (at least in the screenshot)? Additionally, this seems to happen when using FaceTime or any other application that takes up CPU. I have run pmset =g thermlog and seen throttling in the past, but I'll monitor it now more often. Is there a way to turn off dynamic frequency scaling?
