SPEC.org says on the SPEC CPU95 benchmark:

SPARCstation/server 20 Model 71		3.11		2.82
(March 96, 75MHz SuperSPARC II)
http://www.spec.org/osg/cpu95/results/res96q1/cpu95-960228-00485.html

SPARCstation 20 Model 151		4.02		3.77
(March 96, 150MHz HyperSPARC)
http://www.spec.org/osg/cpu95/results/res96q1/cpu95-960228-00487.html

HyperSPARC *needs* high clock frequencies, as can be seen here, to 
perform well.

yes, that's why they're not supported. put in two hot HDs and there's 
really a problem. build in better fans, and you can go for a quad 
HyperSPARC with two HDs.

i really like the HyperSPARC, but i'd only use top end because the speed 
increase of non top end HyperSPARCs is not worth money/time/etc. spent.

furthermore, in most workloads the huge cache of the SuperSPARC II 
really is important.
