1 FPU for 8 cores is wild, but then again they were selling webservers.

Still, iirc FPU's were silicon heavy back in those days and it'd be interesting to know how far ahead the foundries Sun and Fujitsu were, maybe it was simply a factor of being too far behind in the foundry race that left Sun with few options.

Intel's E-Cores still are functionally complete for most parts though (excl Avx512?)? Todays limits seems to be memory bandwidth and power and I guess many of the 144 core customers are in it for virtualization and servers?
