Power and Temperature
To test the power and temperature we performed an “all-out” “maximum threads maximum performance” “full load” scenario. In this scenario, we run Cinebench R23 for 10 minutes and record the power and temperature. This shows the power and temp with the CPUs flat out, foot to the floor, pushing them as hard as possible. We report the data from HWiNFO64.
Power – Maximum CPU Usage Cinebench R23
The Ryzen 7 3700X and Ryzen 7 5700G are 65W TDP CPUs, while the Ryzen 7 5800X is a 105W TDP CPU. This shows in the power utilization testing, where the Ryzen 7 3700X and Ryzen 7 5700G matched each other pulling 88W of CPU Package Power at the default motherboard settings, set on “AIO” in the BIOS. The Ryzen 7 5800X consumed much more power, 54W more or 61% more power. It was the fastest CPU, but it took 61% more power to hit the performance levels shown in this review. The 5700G is, therefore, a great value and performance per Watt.
Temperature – Maximum CPU Usage Cinebench R23
Naturally, the power draw also affects the temperature. The Ryzen 7 5700G ran at 58c max, just 2 degrees warmer than the 3700X at 56c, which is a good temperature. The 5800X at its high power usage was up near 80c at maximum, a good 37% hotter. The 5700G is a power-efficient, and cool-running CPU.
