Before I pull the trigger on purchasing a replacement for my 2011 MacBook Pro, I'm trying to determine which CPU will stay cooler when under load between the i7 & i9. I've already seen the thermals of the i9 which clocks down to between 1.7 & 1.8. That number tells me the i7 could have a chance to do better under load if it is more efficient with thermals. Could someone run a test to check that out? You'd need to install intel power gadget to monitor the heat while using Heaven benchmark to load the GPU while running enough of the following commands to get the CPU to ramp up. You should start with loading the CPU to 100% & verify using activity monitor as each null command will only load some of the CPU, not all. Run this in thermal: yes > /dev/null After you are done with the test, you'll need to use activity monitor to terminate each null command. This will not damage your MacBook as it will throttle like every other laptop. Also, you only need to run it until the CPU throttle stabilizes The result should look like this: upload_2018-11-22_10-34-29-png.805884 (image provided by IdentityCrisis) Again, this is to evaluate the i7 Vega 20 MacBook Pro. Thanks to whoever benchmarks this!
