I found that MacBook Pro 2019 runs faster if I close the lid when using an external monitor – 2.7 GHz (base 2.4 + turbo) vs ~ 1.5 GHz due to thermal choking. Must accept that these things can only run one screen fast.
I’ve never had this problem with the MacBook Pro 2012. I’m glad I bought the 16-inch, because the Big Sur does not support the original Retina model, but the new one is a regression in this and other basics like the trackpad, touchline and keyboard.
