FPU NexGens have been available for the past couple of months. Non-FPU
NexGens perform sometimes a bit better, sometimes a bit worse, than
comparable Pentium CPUs on non-FPU tasks. I don't have a NexGen with FPU so
I don't know how well it works.
FreeBSD 2.1R runs just fine on my NexGen PCI-90. The standard FreeBSD FPU
emulator also works fine but it *is* slower than Christmas. Otherwise my
NexGen is quite a screamer and has totally lived up to my expectations. The
term "junk" used above is totally out of place.
One rainy day I plan on testing the Pentium-specific optimizations in gcc
and see if they help a NexGen.
