MBP 16 thermal and noise tests between low and mid models?

[buran-energia]

Anyone knows any thermal and noise test results out there between the base Macbook pro 16 model and the higher tier one (8 core, 5500M) in high load scenarios? Bonus points for also including MBP 2019 15 8-core and vega 20.

I would also like to know. I have the 2.4Ghz i9/32GB/Radeon 5500M 8GB and I hear the fans spin up louder and more frequently than my 2015 MBP (2.8Ghz i7/16GB/Radeon M370X 2GB).

I don't have any equipment to measure the noise though.

I would be very interested about such information, too!

Found one video (at around 3:35):

The machine with 5500m is louder than 5300m, but I don't get it. He manually set the fans to the max? Don't they have the same cooling and fans? Or is it because Apple limits max fan rpm in firmware for each model? Both sound a lot nosier than the 2019 with 560x he compared to.

Hi, I don't know. In the end I don't care how it is done. What matters to me is a machine that is silent in light/medium use. When it is being pushed, I don't mind in the fans being loud. And the video you referenced at least showed that the 5300m model is more silent under full fan speed. So I would assume that it generates less heat. I would really like to have 8 cores for software development. But I think I can get by with 6 cores. I had the MacBook Pro 2016 15" with 4 cores and that was a fast machine that seldomly got loud.

I am actually thinking on sending my base Core i9 model back and try the base Core i7 model
