According to Puget Systems, AMD CPUs are less reliable than Intel processors. As a reminder, Puget Systems is an assembler of high-performance custom machines, and the company shares its return rates with us.
AMD CPUs more problematic?

According to the figures they’ve published, Ryzen 5000 and 7000 CPUs have higher return rates than 13th and 14th generation Intel CPUs. In fact, these two generations are said to have a return rate of over 4%, compared with just over 2% for Intel. Worst of all are the 11th-generation Core i’s, which soar to nearly 8%.
Clearly, let’s take a step back from what’s indicated here. The first thing to consider is sales volume. Ryzen CPUs are still older than their Intel rivals. Potentially, the company has sold more Ryzens, hence their more significant failure rate.
Secondly, the company does not hesitate to apply its own bios profiles to its Intel systems. As a result, the company respects Intel’s basic profile parameters and even goes a step further by applying its own power management parameters. This should limit the damage.
In any case, we await Intel’s corrective patch. This should arrive by mid-August, so we’ll be keeping a close eye on feedback. It has to be said that AMD has also had its share of controversy, notably concerning the X3D CPUs, whose 3D V-Cache die tended to burn out as soon as a certain voltage was reached!
