Well, this (very long-time) member of the forum doesn't agree. I'm not saying that you haven't had issues because anything is possible. All I can say is that I've owned the following CPU/APUs: Phenom II X4 940, Phenom II X4 965, A8-3500M, FX-8350, R7-1700, R5-3500U and R5-3600X. That's a pretty long time of having only AMD CPUs in both desktop and mobile devices. They've been 100% stable so the idea that AMD's chips would be something other than perfect would be a shock to me.
Even on the Radeon side, the only instability I'd ever encountered was with the RX 5700 XT and that was because of the power delivery system on the XFX RX 5700 XT Triple-Dissipation card. XFX replaced it with the THICC III model and I've had no problems whatsoever since then. As for my ATi cards, I've had two of the following (and used them in CrossfireX): HD 4870, HD 7970 and R9 Fury. Since nothing uses Crossfire anymore, I also have one RX 5700 XT and one RX 6800 XT. Other than the problem with the Triple-Dissipation XFX card, I've had no stability issues with any of them and gamed quite happily with them.
Actually, now that I think about it, there was one stability issue with a card that I ended up returning and replacing with the Gigabyte Windforce HD 7970 which was the Powercolor HD 7870 XT. It would crash as soon as Crossfire was engaged. However, that was an oddball card (that should have been called the HD 7930 because it was a very cut-down Tahiti GPU) and the only card to use the XT suffix between the X1900 XT and RX 5700 XT. To this day, I don't know why Crossfire crashed the cards because the single-card performance was flawless. I brought my PC to NCIX and he tried six cards and they all behaved the same way.
If I had encountered significant issues with AMD products, believe me, I wouldn't be defending them. To this day, I still won't buy anything from MSi because I bought a K9A2 Platinum motherboard, their flagship motherboard at the time and it failed after 16 months. Since the warranty was only 1 year, they told me to get stuffed. I replaced it with a cheap ECS Elitegroup board that still functions in my mother's computer to this day.
I'm not a fanboy, I'm a hater.
