Ron Natalie recently stated that a Gould PN 9000 machine could deliver 10 x VAX780 for $400K CPU price, and the fellow from DEC asked "do you really believe that?". About 8 weeks ago, I published the results of my benchmarks on the Gould machines, which can be sumarized simply: 32/8750 (1 CPU): claim 5xVAX780, measured 4.9xVAX780 32/8780 (2 CPUs): claim 10xVAX780, measured 9.8xVAX780 From what I know of Gould's products, these relationships hold: PN 9050 is >= 32/8750 PN 9080 is >= 32/8780 I know of two other UNIX tests done (by others) on PN9050 machines, one indicated 4.5 x VAX780, the other indicated 5.5 x VAX780. I really believe this, because I ran it myself on a machine which was provided to me (at my request) with blank disks and their distribution. I loaded their UNIX in, and ran the tests; no Gould staff were permitted to access the machine while the tests were running. Unless there where hallucinogenic gasses in the machine room during the tests, I have confidence in my tests. Anybody wishing the full details of my tests can send me mail. As with all benchmarks, remember that "your mileage may vary".
