Here we are at the end of Ryzen Part Deux and I have to say that, for the most part, scaling the architecture down does hit on some performance points. As you might expect, the results to show and prove that dropping the core count by 50% on the Ryzen 1500X did reduce performance in multi-threaded benchmarks by close to 50%. No real surprise there since 50% of the core count should equate to roughly 50% of the performance of a similarly clocked Ryzen processor. No real surprises are to be had either when you look at the R5 1600X. It fits that sweet spot right between the R5 1500X and R7 1700 perfectly as a six-core / 12 thread part. The IPC improvements with AMD's Ryzen architecture allow these two lower core count Ryzen 5 offerings to stay ahead of AMD's previous powerhouse, the FX 9590 that is clocked 1.1GHz higher than the R5 1500X right out of the box. The added core count of the R5 1600X pushes that performance envelope higher so that it's more competitive with the Intel product stack in our benchmarks.”
