As is traditional for Bitcoin hardware it’s late and below the advertised specification.
It’s normal to tape out, order a few engineering wafers, test and then have a production run a few months later. Cointerra ordered hundreds of engineering wafers to expedite the process
Alternatively ... Bitcoin hardware is traditionally late because the designers want to get a head start in the mining while their device has a clear advantage and before their paying customers start competing. This time they ordered 100s of engineering wafers to improve their edge.
Same as the old gold rush adage that the only people making money are the ones selling the shovels.
