I'm not sure I can agree with that. First, most SPARCs had much
larger caches than x86 implementations of the same era. Second, there
wasn't much that higher-end SPARCs couldn't do faster than higher-end
x86 implementations. There were the crappy SPARCs, like the IIi and
IIe, but they don't count in my book. ;)
What really helped to kill SPARCs, assuming they've actually been
killed (I've seen no formal announcement of their discontinuance), is
Dave McGuire, AK4HZ
New Kensington, PA
