Ryzen R9 5950X power testing results

At stock, the Ryzen 9 5950X reports 125 Watts being used under full load while running loops of Cinebench R20. That’s 7 Watts lower than the Ryzen 9 3950X doing the same task. When we kicked in PBO mode for the 5950X, an additional 94W were pulled for a total of 219W of power draw.

One thing to keep in mind is that PBO has a much larger impact on the R9 5950X’s power consumption compared to its lower core count siblings. It simply takes more power to max out the performance of all 16 physical cores at the same time.


Ryzen R9 5950X temperature testing results

From a temperature perspective, the Ryzen 9 5950X registered 3 degrees Celsius cooler than the Ryzen 9 3950X while running loops of Cinebench R20. Turning on PBO pushed the temperature up to 81.4 degrees Celsius which is a bit warmer than we’d want to run the chip on a full-time basis. Keep in mind the PBO temperature was achieved on an open test bench with a 360MM radiator – anything less will report higher temperatures.
