Just wished I had better control on AMD GPU being used whenever I plug in a display for my MBP16, just ramps up the fan for no reason while my Air is just sipping away on the same display with iGPU..
- windowsrookie 5y agoUnlike Windows based machines, MacBooks always use the AMD GPU when an external monitor is plugged in. I forget the exact reasoning, but it is the way Apple designed these machines. In 2016 when they were redesigned I don't believe the intel IGPU could drive 4k @ 60hz, and Apple also wanted compatibility with the LG 5K display they partnered with. The best solution was to just force all external displays to be routed thru the AMD GPU.
- DarthNebo 5y agoI've seen articles about the low-power mode being rolled out to macOS Monterey, even for intel Macs. Hopefully that can reduce power consumption. I've also decided to do a thermal pad mod for the VRMs+inductors to reduce throttling, avoid higher top-side temperatures & lower fan noise.
