I've been tweaking my Windows Power Plans to bring my Macbook's (2019 15" Vega 20) cpu usage down (along with the fans) during gaming.
The unfortunate thing is changing the maximum processor state below 100% allows me to control it to from basically idle performance to max w/o turbo boost (e.g. like 500mhz to 2ghz). The problem is I can't control Turbo Boosting and have it boost above the base clock of 2.2ghz without boosting the most it can in the thermal headroom. So there's a huge jump from about 2ghz to 4.2ghz. 2ghz seems fine for plenty of games, but there are others that start to chunk and 3ghz would be great and still bring the fans down a little.
Any advice on software to control boost targets/ghz limit?

Hey all, I think I found the best solution: Intel ETU.
It seems like the macbook pros are a bit limited -- the H and HQ CPUs either turbo boost fully or not, and can no longer control the boost multipliers. Further you can't seem to undervolt the CPU, at least out of the box. Therefore tools like ThrottleStop aren't very useful.
XTU on the other hand let's you config Turbo Boost Max Power. I just set that down to 25w. Previously it would limit at around 40w so this constrains the power and forces it to use a lower multiplier/voltage. Hope this helps.

Hey kickstep,
Was going to recommend ThrottleStop. You can disable turbo all together, and more.

Intel Extreme Tuning Utility is better for setting for specific clock speeds. Setting the cores and multipliers works at limiting Turbo Boost clock speeds. ThrottleStop has the advantage of disabling the Turbo Boost, and that works really well with Macs Fan Control at full blast at lowering the temperatures.

I just set the max processor state to 99% or less to lower the CPU clock as much as possible without it becoming a bottleneck. I find in gaming the CPU hardly sees any utilization past 30% yet it keeps turbo boosting/using the full base clock, thus generating unnecessary heat. Granted I mostly play older games and also cap the fps at 60.
