Supercomputers are measured based on 64 bit floating point operations. Here they (inaptly) compared it to their 8 bit floating point operations (which are only useful for AI workloads).
If all you care about is an 8-bit AI workload (there's definitely a market for that), it's nice to have 24x the speed.
AFAIK, there wasn't a faster 8-bit super computer to compare to - which is why they made the comparison.
