I just received my 15" i7/32Gb/1Tb/Vega 20 after UPS showing back and forth that I'd get it today or tomorrow. I have access to a very nice thermal imaging camera thru work so I thought I'd compare it to the other two laptops I have available to me. The middle one is a Yoga 720 15" i7/4K/GTX 1050/16Gb/512Gb and the one on the left is an HP x 360m i5/8Gb/128Gb. The two Windows machines are about 6 months old. The Macbook clearly ran cooler than the other two. Below are some shots of the Macbook's benchmarks. I've also got video of them running Cinebench, but of course Fluke doesn't have a MacOS version of their software to convert it to a usable picture or video.
Let me know if you have any questions.
