For the latest sharp Ryzen 7000 series processor, the most groaned is afraid of the heat problem. But according to AMD, the Ryzen 7000 itself is designed to run 24/7 at 95°C for its entire life cycle.
AMD officials posted in the community that all quality analysis work on the Zen 4 desktop processor was done at 95°C and that this is the best performance target the chipmaker has set for several older Ryzen series.
The AM5 has a PPT (processor socket power limit) of 230W, the maximum power consumption limit the processor is allowed to utilize, with a TjMax of 95 °C.
The gaming performance of Ryzen 9 7950X can be said to be almost identical on stock air-cooled coolers and NZXT Kraken X63 water-cooled coolers, according to.
With Cinebench test results, air cooling suffers less compared to water cooling, but can be restored with some adjustments: …
AMD also gives the Ryzen 9 7950X adaptive cooling solution to maximize the performance of a given configuration. The final results show a 4% performance loss under air-cooled conditions as the power consumption algorithm is tuned to meet the 95°C limits.
While the bottleneck for Ryzen 9 5950X is said to be power rather than temperature, the opposite is true for 7950X. Thanks to the higher 230W limit, it will hit the temperature limit before the power hits the wall, even with the TDP set to 105W.
"As you can see in the comments, under intense all-core workloads (e.g. CB nT, Blender, etc.), the CPU will operate at around 95C, but running the same workload on the 5950X may see significantly lower temperatures. This difference is not a change in the way PB2 operates, but rather the result of higher socket power limits. In short, a Raidon processor will continue to ramp up performance until the power or temperature limit is triggered. the Ryzen 5950X temperature is limited by the 142W PPT power limit, while the Ryzen 7950X has more power, so it will reach the temperature limit before it hits the 230W PPT limit. If you want to do a like-for-like comparison, set the 7950X to the 105W TDP setting in the table above, and then check the PPT and temperature readings. You should see that the 7950X is well below 95C, but at 142W max. It will also score significantly higher in Cinebench nT than the 5950X, indicating the 7950X's true efficiency and IPC improvement in the process."
- 95 degrees Celsius is the absolute safe temperature for Ryzen 7000 series processors throughout their product lifecycle
- 95 degrees Celsius is the target for maximum multi-threaded performance with these smart processors
- A better cooler means better performance, but that doesn’t mean you won’t get a better experience from it than air cooling
- Don’t confuse the measured temperature with the heat generated by the CPU, as heat is purely a function of power consumption
To summarize, buying a better cooler won’t improve gaming performance, because temperature is not a limiting factor for the Riptide 7000 series processors.
