batch 1 to batch 1 they are identical price wise for hashrate. Batch 1 of z9 mini was $2k, so if you ordered 1 A9 you'd be paying the same $/sol rate but at a better power ratio and what sounds like an earlier shipping date. So people that manage to get A9's asap will have a nice leg up and the first batch of mini's could very well be shit now.
