AMD Ryzen 9 7950X Energy consumption and temperatures …
In terms of energy consumption, the AMD Ryzen 9 7950X shows its best side just like the AMD Ryzen 5 7600X after some tuning! The progress in the manufacturing structure size of 5nm is now fully effective. For better illustration, we show a comparison table with standard settings as well as the previously mentioned performance preset “PBO, 85°C and Curve Optimizer -40mV”. We also include values from a Ryzen 5600X with activated PBO. Cinebench R15 is our review of choice because it is purely CPU-limited and therefore scales very well with the power settings.
| CPU | Cinebench R15 | CPU frequency | PC Power consumption |
| AMD Ryzen 9 7950X Standard | 6127 cb | 5250 MHz | 319.1 Watt |
| AMD Ryzen 9 7950X PBO | 6411 cb | 5502 MHz | 300.3 Watt |
AMD Ryzen Heat generation …
With the Performance Preset enabled, the CPU’s power consumption is significantly reduced both under load and idle, and the Cinebench R15 Multi Core benchmark delivers an even higher result due to the overclocking. However, you should not forget that a purely CPU-heavy test was chosen here and only one CPU was tested at a time. With other applications and other specimens of the AMD Ryzen 9 7950X, the results can naturally deviate from our measured values. The other components of the PC, especially the cooling, also play an important role in the overall performance of a computer and future BIOS updates as well as Windows updates will also influence the performance.
The new 7600X easily outclasses a Ryzen 5600X processor, which is already maxed out by PBO and Curve Optimizer, by 25% in Cinebench R15 with standard settings, and the AMD Ryzen 9 7950X can of course increase this significantly. The CPU was already running heavily at the temperature limit without water cooling, but it did not have to throttle yet thanks to the two powerful 120mm fans on the Arctic Freezer 34 eSports Duo air cooler. However, the AIO water cooling was indispensable for a higher AMD Ryzen 9 overclocking. Here you can see a thermal image with the new heatspreader of the CPU without any cooler.
To get an even better impression of the heat distribution on the new AMD Ryzen heatspreader, we have posted an interesting video on our OCinside YouTube Channel where we filmed the AMD Ryzen 9 7950X processor without a cooler from PC power-on to automatic shutdown with our thermal imaging camera. The IR thermal movie runs at real speed. Even though the protection features of the motherboard and the processor work really great, you should of course never run the CPU without a cooler – so don’t imitate 😉
