Phoronix published a review on the AMD Ryzen 3 1200 & Ryzen 3 1300X Linux Performance
A quote from the article:
At the end of July AMD began shipping the Ryzen 3 entry-level Zen processors. While it may not be as exciting as a 16-thread Ryzen 7 or Threadripper, the Ryzen 3 1200 and Ryzen 3 1300X offer surprising value with being quad-core parts priced at just above $100 USD. With Linux users especially craving multi-core systems if running Arch or other distributions where you are frequently compiling your own packages, the Ryzen 3 CPUs can make for a low-cost but practical Linux system. Here are my initial benchmarks of these first two Ryzen 3 processors.AMD Ryzen 3 1200 & Ryzen 3 1300X Linux Performance @ Phoronix
