I wonder if it classifies as a general purpose microprocessor. It’s common to see very specialized chips run faster than a typical CPU, but you’re not going to run a consumer OS on it (if an OS at all). Even then, you’d sometimes need dedicated math coprocessors even if you had a CPU back then. It would be fascinating if it was true, cause that would likely mean it’s also the world’s first chip with an integrated math co-processor (IIRC)
