I got my paws on a Mac II the other day, so here's a set of Dhrystones for all Mac series machines and some others: Machine Compiler CPU OS Registers No Reg IBM PC ci-c86 8086 PCDOS 2.0 390 390 IBM AT Miscrosoft C3.0 80286 PCDOS 3.0 847 833 VAX 11/750 Vax-11 C 2.0 -- VMS 1091 958 VAX 11/780 cc -- Unix 5.2 1562 1515 VAX 11/785 cc -- Unix 5.2 2083 2083 Sun 3/75 cc 68020 Sun Unix 4.2 3571 3333 Macintosh Plus LightspeedC 2.01 68000 Mac ROM (128K) 877 806 Macintosh SE LSC 2.01 68000 Mac ROM (256K) 1041 980 Macintosh II LSC 2.01 68020 Mac ROM (256K) 3333 3125 The Sun's 68020 is clocked at 16MHz, I believe; the Mac II is at 15.7 MHz. The non-Mac results may be out of date; I had a long sheet of Dhrystone results that I got these results from. --Rich

This is what I got: Machine Compiler CPU Registers No Reg Macintosh Plus MPW C 2.0b2 68000 714 675 I haven't run it on a II yet, but the results from a II prototype with MPW C were also slower than Rich's for LightspeedC, even when 68020 code generation was specifically enabled. -- Joel West {ucbvax,ihnp4}!sdcsvax!jww or jww@sdcsvax.ucsd.edu

Who's right? According to Chapter 1 of "Macintosh II and Macintosh SE Cards and Drivers" the correct clock speed for the II is 15.6672 MHz. Coincidentally, this is equal to the pixel clock rate on the older Macs, and twice the clock speed of the 68000 in the older Macs. >P.S. And how about a 25mhz Mac II? Maybe on a NuBus card. -- Stew Rubenstein Cambridge Scientific Computing, Inc. UUCPnet: seismo!harvard!rubenstein CompuServe: 76525,421 Internet: rubenstein@harvard.harvard.edu MCIMail: CSC
