Robert Hallock of AMD has clarified that temperatures up to 95/90 degrees for Ryzen 7 and 9 based Zen 3 are normal and do not affect the life cycle of the chip.
Hallock has commented that we must change our way of thinking, and that we must know how to differentiate between what is wrong and what is undesirable. That high temperature range allows, according to him, that the Ryzen 5000 processors have more leeway when it comes to adjusting and maintaining their maximum frequencies for longer.
Robert Hallock says: “I want to be clear with everyone that AMD views temps up to 90C (5800X/5900X/5950X) and 95C (5600X) as typical and by design for full load conditions. Having a higher maximum temperature supported by the silicon and firmware allows the CPU to pursue higher and longer boost performance before the algorithm pulls back for thermal reasons.
Is it the same as Zen 2 or our competitor? No. But that doesn’t mean something is “wrong.” These parts are running exactly as-designed, producing the performance results we intend.“
Apparently, the silicon and firmware in the Zen 3 allow the CPU to reach these temperatures to achieve higher speeds for longer, and thereby extract every ounce of performance from the chip.
Interestingly, Hallock also said that the highest temperature for the 5600X is 95 degrees, before the throttling begins …
For our part we can understand that a Ryzen 5000 with 12 cores and 24 threads has high temperatures when it has 100% of the load, but this does not mean that we should normalize temperatures of 90 or 95 degrees.
Surely, both fall within the thermal specifications of each chip, but they mark a limit that we do not want (and should not) reach.
