This asic is a joke. The prototypes never got to production. They were only able to manufacture a few hundred and never sold them to the public because there were too many problems and completely unstable. Instead they decided to keep them and mine with them themselves and one or two other partners since there would be too many service issues and blowback from failure if they sold them to anyone else. They all have 4.4gb , and are end of life’d this summer anyway as DAG crosses 4.4. They are currently working on an 8+ gb model and will not even start manufacturing them at the earliest next year which again being so close to PoS at that point and give the issues they had with the prototypes it’s likely they’ll just mine themselves on them for a year until PoW ends. Basically they failed to get into production on time and failed to meet quality and realizability standards. It’s unfortunate for them, but Great for gpu miner as they pose no real threat.  They also aren’t really even significant more efficient than gpus these days anyway, especially the 5600xt. Plus when these are end of life’d they are worth $0. At least with gpus you can resell them.
