[comp.arch] In Defense of Decstations

I wish the workstation design, marketing, and benchmarks would pay more
attention to integer performance.  The newest machines are impressive
floating-point screamers.  However, like the vast majority of workstation
users, our day to day applications (software development, ECAD, document
formatting) use only integer cycles.

The Decstation 5000 (based on 25 MHz R3000) has the best integer performance
of any moderately-priced workstation on the market now.

I benchmarked our local ECAD software (logic simulation, routing, test
generation) on Decstations, IBM 320, and our assortment of SPARC and 68k
machines.  The Decstation was fastest on each of our real-world applications.

So if DEC market share is not on a favorable trend, it's not because their
workstations are dogs.  And if they can bring out either an R4000 or a high
clock-rate R3000 desktop this year, they will probably retain the integer
performance lead vs. the FP-optimized RS6000, SPARC, and PA offerings.
