Then you'd love the dual-90MHz ROSS module I've
got (along with a
single-90 module in an SS20 to create a 3 processor "frankenstein"), or
the pair of Dual-100MHz ROSS modules I've got in another machine. The
90s are nicer that the 100s though in my opinion, since they don't take
up any s-bus slots like the 100MHz ones do. (the heatsink on the 100s
is two slots wide because those things run HOT! The 90s aren't
anywhere near as bad.)
Actually the only reason I'd like the dual ROSS HyperSparc modules is to get a Quad
system up and running. I don't like HyperSparc CPU's, a 125Mhz, is about the same
speed as a 75Mhz SuperSparc II.
The one thing I like about it is that even though it
won't take as much
memory, and doesn't have as many SBUS slots (or drive bays), the SS20
with a pair of 100MHz procs is probably just as fast as an 8-way 50MHz
SS1000, and a small fraction of the weight. Of course, you're limited
to IIRC 512MB of ram in the machine...
I don't think so, here are the SpecInt/FP 92 numbers for a SS20.
Sun SS20/50 SuprSP 50 20/16 76.9 80.1
Sun SS20/HS11 HyperSP 50/100 256+8/0 104.5 127.6
While the raw power for a single process might be faster on the 100Mhz HyperSparc, overall
that 8-way 50Mhz will blow it away. Besides if I was putting an 8-way SS1000 together,
I'd be wanting to run it with SM81-2's.
