I've had AMD CPUs on and off since my DX266. I've had a K6-2 300 never overheated, a Duron 1Ghz, Athlon XP 2000, Athlon XP X2 4200+, XP X2 6000+, Phenom X4 9850 which was stolen so replaced by a Phenom 940 black. I stopped upgrading for awhile as I had my son and the company supplied me with decent enough laptops and due to space I just consoled.
But I'm now running a Ryzen 2600.
Not one of those ever over heated, the bulldozers of the 2010s were the inefficient ones that ran hot, which is the generation I missed.
I think you're just a little biased to Intel.
