AMD Ryzen 9 7900X Review

Temperatures
Thermals are a key point to any processor, as it allows it to boost for a prolonged amount of time and depending on the task that’s being performed, thermals can be either higher or lower. To get the best possible picture, we have recorded thermals for idle, during a simulated Cinebench R23 load test, and during a typical gameplay benchmark run of Cyberpunk 2077.
At idle, the 7900X does end up being the hottest CPU we’ve tested at idle at 42.3 degrees. While you’d expect a processor built onto the 5nm process to run cooler, it has allowed AMD to implement integrated graphics and to increase the performance quite dramatically too.
During gaming, our NZXT Z73 RGB 360mm AIO was able to keep all of our processors at reasonable levels with the 7900X running just under 2 degrees cooler than the 5950X but is now sitting just under 8 degrees hotter than the 5900X.
In Cinebench R23, the 7900X did get quite warm, but still sits just under 5 degrees below the quite toasty 12900K from Intel but is quite a bit warmer than both the 5950X and 5900X.
