Tell that to my 2950x, the thing is a heap of garbage...
80% of the time it won't boot at xmp memory speeds...
If it does, it trashes the pcie bus during boot...
Either way, I also had to turn off ASPM, because my nvme drives will crash during boot, or shortly afterwards...
Then there's all the random amdgpu errors it also throws, it's better with everything turned off, but the machine is basically on life support until I can build a new PC.
Zen began to be really better than the competition only with Zen 2 (Ryzen 3000), when the production of its CPU chips was transferred to TSMC.
For Zen 1 or Zen 1+, only the Epyc CPUs seem to have been free of problems.
I have a 24-core Zen 1 Epyc that has always worked flawlessly, but when I have preordered the very first Ryzen, the 1750X, I had to dump it as useless garbage after only a couple of weeks, because I was using it in Linux, where any intensive multi-threaded task was crashed by a nasty bug that was not seen on the Ryzens used just for playing games in Windows.
AMD has never given any explanation about their bug, and they did not recall their CPUs, which were completely unusable for professional purposes. However, like Intel today, they at least honored the RMA requests. However I did not bother with an RMA, especially because the procedure would have been complicated, as I do not live in the USA and I would have had to ship internationally the bad CPU. I have just dumped both the Ryzen 1750X and the expensive motherboard, keeping only the DIMMs, and then I have bought a Kaby Lake instead.
Nevertheless, I did not hold a grudge against AMD, despite losing more than EUR 800, and later I have bought an Epyc and then a Zen 2 Ryzen and then a Zen 3 Ryzen, all of which have worked perfectly.
I got a buggy 1800X, shipped for RMA to a logistics center in IIRC the Netherlands from Germany. RMA took about 2 weeks altogether and it was worth it.
Since then, I've upgraded to the new top of the Ryzen line everytime there was a significant (>40%) increase in compilation performance. The 5950X was a notable dud in that regard.
Recently, setting power limits to get 90-95% of the performance at 60% of the TDP became a thing.
