Of course, we would like to find out the real power consumption of a typical AMD Ryzen 7 system. Since the new AMD Ryzen 7 processors features 8 cores, we do expect that these processing units will consume quite an amount of electricity. We will take the power draw readings from a watt meter that is plugged directly into the wall socket. This wall socket will power solely the whole AMD Ryzen 7 system that we have set up, excluding the monitor. We will run Cinebench R15 to determine the system’s consumption of electricity at peak loads, where all cores and threads are utilized simultaneously. Furthermore, we will also look at the power readings when playing games. We will run the 3DMark Time Spy and Fire Strike benchmarks to simulate such workloads.
- AMD Ryzen 7 1800X CPU @ Stock Settings
- ASUS Crosshair VI Hero Motherboard
- Cooler Master Master Liquid Pro 240
- Corsair Vengeance 3000MHz DDR4 2 x 8GB Kit (1.35V)
- ASUS NVIDIA GTX1050 Dual
- OCZ TL100 240GB SSD
- FSP HEXA+ 550W
- Windows 10 Enterprise 64Bit
In our tests, it seems that the whole system take up an average of 62.6 watts on idle. This is quite typical of most systems out on the market. Moreover, we are also running a rather efficient graphics card which should not take up too much electrical power.
In the CineBench R15 test, which simulates the full utilization of all CPU cores and threads, we saw a surge in power where it peaked at 208.3W. This can be explained with the increased voltage that is applied across the CPU core, during the CPU Boost and XFR clock increase. We can also see the additional power that the CPU itself can draw, specifically by comparing it with the idle power consumption rates.
In lighter games, we can see that power consumption was largely increased due to the consumption from the graphics card. However, there was a significant increase in the power consumption whenever a CPU related benchmark was run. This also shows that the CPU takes up the bulk of the power consumption in this system. We did not fully test the capabilities of the graphics card and its power consumption as it is out of scope for this test, but we can expect similar rates for a gaming setup that uses the same type of graphics card.
