Thread: Re: UltraSPARC versus AMD - Slowaris
Richly deserved IMNSHO. my current employer was bilked for many many months
for a piece of crap E10K that barely outperforms a couple of AMD chips. But
at many, many times the price. We finally upgraded/migrated to AIX/g5 chips
and run what was run on 20 cpus on 2.
If Sun pulls out of its slow Icarus dive to near-certain death, it'll be
a miracle. ( And, I guess, that'd be "a good thing"; always nice to have a
miracle. )

Sun's stock was at $65.00 in late 2000 and has rocketed to $3.50. I think somebody else besides us noticed too.

Maybe that's why used Sun E10ks with 12 CPUs and 12 gig of ram are going for $5995 AND still not selling on ebay...
