One aspect of Ryzen CPUs that appeals to me is their support for ECC, which some motherboards facilitate. This makes them a good candidate for small/fast ZFS applications. Unfortunately, most ECC RAM is significantly slower than what Ryzen CPU benchmarks typically use. I would really like to know what these numbers would be like with 2666 MHz RAM, and also how that RAM speed bottleneck looks with other Ryzen CPUs like the 5900X, 3950X, 3900X, and 3900XT. The bottleneck might affect whether or not the 5950X is the best choice for this use-case.
