The claim that these CPUs are 'cutting edge' despite being based on the older POWER9 uarch is dubious as well. I suspect this is simply a marketing sham and the CPUs talos continues to ship will be rebrands of their current offering. That said, if they have the original designs for these CPUs then it's not impossible for a startup to make meaningful improvements, but it almost certainly isn't going to be fabbed on a cutting edge node and certainly won't be competitive with anything else on the market (not that they were to begin with).
