2019 MBP 16" 2.3Ghz i9 severe thermal throttling (Catalina 10.15.5)

# Brief Summary 2019 MBP 16" 2.3Ghz i9 shows severe thermal throttling * CPU Frequency hovers around 1.9-2.0 Ghz * Power draw doesn't exceed 30W * Max Temperature only 76ish degrees Celcius * Exporting a 5min clip on Adobe Premiere Pro which slams all 8 cores I've attached screenshots below showing just how much the new MBP 16" i9 throttles. I haven't really had a problem with it until recently... but there are 2 variables: ## What's Changed? * Catalina upgrade to 10.15.5 recently * Applecare service replaced the logic board ## Questions * Is it likely that the replacement logic board is not up to snuff? * I haven't heard any complaints online (reddit, stack exchange, apple support) of thermal throttling lately. How does one test abnormal throttling? ## Screenshots * terminal output after running

* intel power gadget showing the aforementioned stats holding steady despite high CPU Utilization.
