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.

No kidding!

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.

Something like the Fujitsu PRIMEHPC FX700?

Minimum 128 unit purchase for those outside Japan, though.

A group buy would be cool.

IIRC the extension was specifically designed by Fujitsu for their needs, so it is not surprising.

Not quite, although they were deeply involved for much of it.

I'm pretty sure there's an emulator, which is how you usually do early development.
