You’re seeing roughly an 80-percent difference in performance when all cores are hot on Ryzen 5 and the Core i5. We retested on Cinebench R15, but this time with all the CPU cores and threads available. Running Cinebench R15.038 restricted to a single thread, the higher clock speeds and better instructions per clock of Kaby Lake give it a slight advantage over Ryzen. You’re looking at maybe a 12-percent difference, which ain’t bad, but in the end, still second-best. The Ryzen 5 1600X bounces around, hitting 4.1GHz clock speeds only on occasion. For the most part, the Core i5-7600K sits at 4.2GHz at almost all loads all the time. The Core i5-7600K comes out on top, which is to be expected given its higher clock speed and higher instructions per clock. The first result you see is Cinebench R15 restricted to a single thread. You might recall that this benchmark was fingered by the FTC over alleged Intel benchmark improprieties, but Maxon has claimed its innocence. Our first test is the ever-reliable Cinebench R15, which is made by Maxon and based off a real rendering engine used in its Cinema4D parts. We add Handbrake and Adobe Premiere CC 2017 for video encoding. First, Cinebench for multithreaded performance, then Blender and POV-Ray for image-rendering chops. Our benchmarking begins with a battery of productivity tests.
