Re: "measure what they deliver"
Nah... The Sun Sparc20 got left in the dust by another chip also came out in 1992... The DEC Alpha.
The DEC Alpha was 64 bit and came out initially at 150mhz... while the Sparc was still 32bit and I think started at 40mhz at the time.
It was widely regarded as the fastest chip in the industry from that year until around 1996.
