Power Consumption

Power consumption is something that you should be aware of with regards to processors as someone is going to be paying the electric bill. The processors that we have tested have a wide range of TDPs that you can find in the bullet list below.

  • AMD Ryzen TR 3970X 280W TDP
  • AMD Ryzen TR 2990WX 250W TDP
  • AMD Ryzen TR 1950X – 180W TDP
  • AMD Ryzen 9 3950X 105W TDP
  • AMD Ryzen 9 3900X 105W TDP
  • AMD Ryzen 7 3700X 65W TDP
  • AMD Ryzen 5 3600X 95W TDP
  • AMD Ryzen 3 3300X – 65W TDP
  • AMD Ryzen 3 3100 – 65W TDP
  • AMD Ryzen 7 2700X 105W TDP
  • Intel Core i9-10980XE 165W TDP
  • Intel Core i9-9900KS 127W TDP
  • Intel Core i9-9900K 95W TDP
  • Intel Core i7-9700K – 95W TDP
  • Intel Core i5-9600K – 95W TDP
  • Intel Core i5-9400F 65W TDP
  • Intel Core i3-9100 65W TDP
  • Intel Core i7-8700K 95W TDP
  • Intel Core i5-8400K 65W TDP

The AMD Ryzen 3 3100 and Ryzen 3 3300X both don’t use much power under load as you can see from the chart above. While running all cores/threads on Cinebench R20 the Ryzen 3 3100 topped out on our test system at 118 Watts and the Ryzen 3 3300X topped out at 139 Watts. Our system was water cooled and CPU temperature/noise was never an issue.

Performance Per Watt AMD Ryzen 3600XT 3800XT 3900XRTAMD Ryzen 3600XT 3800XT 3900XT

Most companies talk about perf/W or Performance per Watt these days, so let’s take a look at that real quick. As you can see the AMD Ryzen series does really well on perf/W as the higher the number the better here. The AMD Ryzen 3 3300X and 3100 don’t score as high as the other Ryzen 5/7/9 parts, but they are better than what is seen from the Intel Core i5-9400F and Intel Core i3-9100. AMD once again wins on the performance per Watt competition, which shouldn’t come as a shock to anyone at this point.
