Back when they were still referring to Ryzen CPU's by the architecture name, Zen, AMD relentlessly promoted Blender benchmarks. Everywhere, during IDC, Computex, during launch, and live onstage and in posted videos. At the Threadripper announcement, even during gaming demos.Core i5-8400 drops into a LGA 1551 interface, but as we know from our previous Coffee Lake reviews, it isn't backward compatible with 200-series motherboards. That means you'll have to step up to a 300-series motherboard, even though that means getting no new features in the process. Worse, a rushed launch means the Z370 chipset is your only option for now. Cheaper B- and H-series motherboards, which will cost a lot less, arrive at the beginning of next year. The Core i5-8400 is a locked processor anyway, so the reason most enthusiasts would have had for spending extra (overclocking) doesn't apply here.
