Power Usage and Temperatures

For the last portion of my testing I like to take a look at the less popular areas, power usage and temperatures. For power usage, I test both idle and load wattage draw using a kill-a-watt. This means these numbers include the entire system. To put things under load I have two different tests and because of that two different graphs. I use wPrime but recently have been also testing using the AIDA64 stress test with the FPU setting. So with the wPrime test, the 2700X was up near the top portion of our charts with 175 watts pulled total and 153 for the 2600X. For comparison, the 1700X pulled 152 and the 1600X 139 watts. It's clear that Ryzen 2000 Series while improved is pulling more to push those new higher boost speeds. Interestingly enough when retesting the 8700K and 8400 from Intel their numbers in both tests dropped considerably from my original launch tests. This might be a side effect of the slightly lower performance from the Meltdown patches or Intel has done some major improvements in their micro-code and drivers in the last few months. Either way in the wPrime test it was down, much lower than almost all of the Ryzen CPUs. Don’t worry though, Intel was also up at the top leading the charge with their Skylake-X CPUs to pull the most.

Now the AID64 stress test pulls more wattage, that is why I’ve been moving to it. I’m looking to get a worst case number when possible so here the 2700X pulls 192, 17 more than in wPrime and the 2600X pulled 171. This was much higher than both of the Coffee Lake CPUs. In fact, the two Intel CPUs together pulled less than the 2700X, even after retesting I still have a hard time believing those results honestly.

Surprisingly enough though with that 12nm node the two Ryzen 2000 Series CPUs did really well in the temperature testing. This was done in AIDA64 as well with the same stress test as the power. I tested using a Noctua U12S. Don’t worry I also tested with the Wraith Prism as well but I’ll talk about that another time. Using the same cooler as the rest of the CPUs the 2700X and 2600X were down near the bottom of the charts at 54 and 48 degrees. For reference, the 8700K was up at the top with the 7700K just to compare the efficiency. It looks like sticking with solder for the HIS was a good call ?.
