“Mindfactory’s sales information in repeated articles over several years, and its Ryzen 7 5800X, 5600X, and 5900X RMA rates are 0.58 percent, 0.52 percent, and 0.33 percent, respectively.”

Based on some very rough estimates using mindfactory and amazon sales data, the 9800x3d is in line with or below 5000 series RMA rates.

If there was real cause for concern, the RMA rate should be much higher.
