Yeah, I had to go high-end to get one with enough CCDs to make use of the memory channels. I'm curious to know what all-read bandwidth you see when you run intel mlc on your system. My Xeon W5 was doing ~180GB/s after a lot of tuning, which was very disappointing. The Threadripper does ~320GB/s. From what I've heard, Granite Rapids is supposed to have solved the bandwidth problems that ailed Sapphire Rapids, so your numbers ought to be similar.
