Really wish Fujitsu sold a developer kit with an A64fx chip - its the only shipping ARM chip with SVE that I know of and I would love to get my hands on one to play with.
I don't have any sense of how much these cost to manufacture. There ought to be a market for a A64fx based rackmount server system. If the price isn't outrageous, I'd love to see these sold as an SBC.
