Ryzen 8000 values are never used. The source note names the family and the other module setups. It is not the CPU's official speed. A JEDEC-only list such as 5600/4800 is not this value.

The test system on page 2 is a Ryzen 9 9900X with an Arctic Liquid Freezer II 420. The CPU drew about 145 W. The review text says the VRM peaked just under 46 C, and the sentence names the Taichi, which looks like a copied word. The chart for this board shows thermocouple 1 at about 45.8 C after 30 minutes. The HWiNFO VRM sensor line is higher at about 47 C. The probe reading is stored, rounded to 46. The exact value is not printed.
