Power, Temperature, and Frequency of Ryzen 7 7700
On this page, we are going to investigate the AMD Ryzen 7 7700 power draw, temperature, and frequency. This is a stress test, which means we are pushing each CPU to its maximum potential in all-core load in Cinebench R23 multi-core test for 10 minutes.
Power
We use HWiNFO64 sensor data to record the results. We report on the sensor data for “Package Power” in Wattage.
The new AMD Ryzen 7 7700 has a TDP of 65W, while the Ryzen 7 7700X has a TDP of 105W. We can see these major TDP differences in the CPUs play out. AMD’s goal was to provide a lower TDP part in the “Non-X” CPUs, and they succeeded. The new Ryzen 7 7700 only consumed 90.1W package power, while the Ryzen 7 7700X consumes 143.2W. That is a 37% reduction in power usage, yet only a 7-8% reduction in performance at most.
Enabling PBO on the Ryzen 7 7700 allows the TDP to increase, and what we find is that it reaches much closer to the TDP of the Ryzen 7 7700X. That allows its performance to come very close to the performance of the Ryzen 7 7700X in our testing as was shown. However, even though it has increased, it is still using 20W less power than the Ryzen 7 7700X. Overall, it’s still a power saver on efficiency, even with PBO enabled, and you gain almost the same performance as the 7700X.
Temperature
We use HWiNFO64 sensor data to record the results. We report on the sensor data for “Tcidle” in Celsius.
We know that there is a big power difference between the CPUs, and we also see this represented in the temperatures. The Ryzen 7 7700X tops out at a very hot 75.6c, remember this CPU utilizes one CCD, and that concentrates heat quite a bit. The Ryzen 7 7700 only maxes out at 67.4c, which is a huge temperature difference. This means you do not need excessive cooling. Also remember, the Ryzen 7 7700 comes with a cooler that works well for its temperature range. Enabling PBO does increase temperature, as it increases power, but it still runs cooler than the 7700X.
CPU Frequency
We use HWiNFO64 sensor data to record the results. We report on the sensor data for frequency in MHz. The left screenshot is the Ryzen 7 7700 at default, and the right screenshot is the Ryzen 7 7700 with PBO enabled.
From this, we can see that the Ryzen 7 7700 at default operates at 4.825GHz-4.850GHz at default. Remember, the CPU boost frequency can boost up to 5.3GHz technically, but on all-core load, this is as high as it will go when all cores are being used.
When we enable PBO (in the right screenshot) we now see that it can boost up to 5.050GHz on every core. That is a solid 200MHz frequency bump from enabling PBO when all cores are used. This is quite a big boost in frequency, and this is why the Ryzen 7 7700 can almost reach the performance of the Ryzen 7 7700X when PBO is enabled.
