Help understanding Ryzen 4500u Thermal Sensors


New Member
Hello, I'm using HWinfo64 on a laptop with a Ryzen 4500u processor. I'm looking at the CPU thermal sensors, and there's 5 readouts. I'd like to know what each one represents, specifically the first 3 - CPU (Tctl/Tdie), CPU Core, CPU SOC.

From my understanding, CPU Tctl/Tdie is the single hottest temperature measured within the CPU Package, and CPU Core is likely the temperature of the CCD? Also curious how CPU SOC and APU GFX differ from one another, all very confusing stuff. o_O 4500u thermal sensors.png
