This has been debunked. PowerGPU deleted the tweet, PC World gathered data from other vendors.
Ryzen 5000 series fails at 2.9 percent.
Ryzen 3000 series fails at 3 percent.
ThreadRipper 3000 series fails at 2.5 percent.
Intel 9th-gen fails at 0.9 percent.
Intel 10th-gen fails at 1.2 percent.
3% which is higher than Intel but their 14nm is far more mature.
These CPU's are also NOT DEAD, as PowerGPU reported, they are rejected for failing their torture test requirements, that being stress tested with high frequency RAM with all RAM slots occupied. "They didn't pass muster for frequency or letency"
Other tech journalists had spoken with their countries retailers, Hardware Unboxed reported under 2% failure rates for Ryzen 5000 in Australia, Mindfactory reported under 1% for Ryzen 5000 in the EU.
