Power Usage and Temperatures

In addition to performance testing, I did look at a few other aspects. I hooked our testbench up to our Kill-A-Watt and tested both idle and load power draw. This is of course including the base power draw for the board, the GTX 1080 Ti, and the SSD but every CPU tested was done in the same situation so they are comparable. The idle performance as a whole still isn’t as good as Intel’s CPUs but it was better than the older Intel and AMD CPUs. For load I used wPrime to put each core under load and tested power draw again, noting the highest peak wattage. The 1300X didn’t do too bad at 91.2 watts but the 1200 did much better with just 72.1 watts. Even not considering the performance that is impressive.

For temperatures, testing is a whole can of worms really. The only true way to get temperatures is to use your own sensor on top of the CPU die so the numbers here are only worth so much. Our testing is done using AIDA64 and sometimes, like at the Ryzen launch you will find things like a 20 degree gap in actual temperatures and what the CPU is outputting. But I still include these for at least some reference. Both Ryzen 3 CPUs officially have the same 65-watt TDP as the Ryzen 5 CPUs under the 1600X. Of course having fewer cores and in the case of the 1200 with lower clock speeds as well the actual power draw and heat output is going to be lower. The 1300X with its higher clock speeds come in close to its 1500X brother and in the middle of the other Ryzen CPUs. The 1200, on the other hand, came in much cooler with 43 degrees at load, both being tested with a full sized Noctua NH-U12S.
