I have one for round about two weeks now, 8GB RAM, 512GB SSD, around € 1550,-. If it's a sensible, not too much time consuming test, drop me a line and I will post the results here.
BTW, I don't understand these OS/Hardware wars you all are doing here in the forum. And, IMHO you are comparing apples and oranges all the time. Are you guys seriously thinking that a € 3500+ equipment can be beaten by hardware for € 800 (Mini), € 1100 (Air) or € 1500 (Pro)? Or that the main class of customer is someone mainly crunching numbers (letting a chess engine running all the time is nothing but number crunching)?

PS. I'm not an Apple fanboy. I also use Windows/Linux/FreeBSD (PC) and Android (Tablet, Mobile phone). But my last Notebook was a Mac Book Pro late 2012, bought in 2013 for around € 2500,- , which after nearly eight years still works flawlessly and beats most of todays low cost notebooks in many ways. And, so far I'm impressed by the new M1.
