Athlon II X3 vs. Ryzen 3: How AMD's Performance Has Evolved & Performance-Per-Watt

You will also find much better gaming performance with the newer CPUs.

Lastly is a look at the AC system power consumption over the course of all the benchmarks carried out for this article. The Athlon II X3 425 configuration had a minimum power draw of 98 Watts, average of 128 Watts, and peak of 164 Watts. The AMD Ryzen 3 1200 meanwhile had a minimum of 62, average of 86, and peak of 181 Watts. The AMD Ryzen 3 1300X had a minimum of 67 Watts, average of 102 Watts, and peak of 197 Watts. The higher peak system power consumption with the Ryzen 3 CPUs are during the gaming tests where the GPU was kept busier in a higher power state due to being less CPU bottlenecked than on the Athlon II X3.

So for those curious how AMD's low-end CPU performance has evolved from Athlon II X3 to the Ryzen 3, hopefully you found our latest benchmarks interesting.
