Recent investigations by Igor's Lab and Hardware Busters have revealed that AMD's Ryzen 7000 and Ryzen 7000X3D CPUs are consuming unexpected levels of power in short bursts when running in idle mode. Further tests conducted by Igor Wallossek and Aristeidis Bitziopoulos have found that these processors are producing power spikes during minimal computing activity, causing slight concern among testers. It is currently unclear whether these spikes are related to the burnout issues experienced by overclockers this week.
Aris from Hardware Busters has tested many of the affected processors in the past but did not encounter any major problems relating to burnout or power consumption spikes. However, new tests using his own Powenetics v2 board have revealed some interesting facts. For example, the 7950X3D has a high spike during idle at 130 W, which is unjustified given that the peak CPU load is only 3.53%. Even with the Curve Optimized enabled and a -15 setting, the idle power spike is close to 125 W. On the 7800X3D, the spike during idle stays low, but this is not the case for the 7900X, which has an idle power spike at 109 W, while the peak CPU load at idle was at 5.12%. Video coverage of the matter has been provided by Hardware Busters in their "AMD Ryzen 7000 Series burn issues? Our Findings!" upload to YouTube.
Igor does not believe that these load peaks are related to the described CPU dying, but he and Aris emphasize that such transients are not ideal for a stable system. Aris has also spoken to industry contacts who have reported that the overall RMA rates of the 7000 series are lower than those of the 5000 series. Therefore, there is no need for panic or discouragement from buying a new AMD CPU.
