I bought a 3700x in 2021 and after 2 years of my computer randomly powering off (and replacing my PSU, ram and GPU in that order) I replaced the CPU and found that the problem was fixed. I sent the CPU back to AMD and they confirmed it was defective and issued a replacement. I haven't had a random poweroff since.
perhaps I am just unlucky, but I think I'll take my chances with intel
Wait, that was your takeaway? I understand cumulative frustration is hard to reverse, but it seems pretty solid that they accepted an RMA two years after purchase, reported test results, and replaced it.
As much as I try to resist brand loyalty, I feel like that kind of support experience would probably bring me back next time.
