AmInfo.DOC v1.0 ŠLeclercq Xavier 1992 ------------------------------------- ENGLISH VERSION First: ------ If your Kickstart version is lower than 37.175 (ROM 1.2/1.3),and if you have an accelerator card, you have to run SETPATCH (>=v1.34) to prevent some exec.library bugs ! The following information is displayed only if your kickstart is higher that 36.xx (click on the VERSION button to get your kick. version). "CIA Clock Frequency" (KHZ) About AmInfo 1.0 : ------------------ AmInfo v1.0 has beeb completly written in assembler. The source code (about 100 Kb) contains for a large part (1/3) a CPU speed calculation routine that has been made possible with an utility from the AmigaLibDisk n°1. Thanks may go to Mr. Rick Richardson for translating the ADA code. This CPU speed that has a quite good precision when comparing the Amiga performances with others systems (or configurations). CPU SPEED: (AmInfo precision: +- 0.1%) ---------- <<< NOTE: The RAM chips speed may modify the result of the test >>> <<< The ŠTESTIT (PC) seems to show some exageration... >>> Un [lame] PC/XT "Turbo" 8 Mhz : 350 Dhrystones/secs A500 (512 K) : 598 Dhrystones/secs KCS Pc Board : 750 Dhrystones/secs PC-AT/6 Mhz : 1000 Dhrystones/secs A500+ (4 Mb) : 1086 Dhrystones/secs PC-AT A2286/8Mhz for A2000 : 1492 Dhrystones/secs A2000 + 68020 A2620 : 2860 Dhrystones/secs A2000 + 68030 Commodore (*) : 3906 Dhrystones/secs IBM 386/20 Mhz (model 70) : 4360 Dhrystones/secs A3000 (new motherboard) : 6265 Dhrystones/secs Compaq 386/33 Mhz : 9200 Dhrystones/secs A2000 + 68030/68882 50Mhz... : 10400 Dhrystones/secs DISPLAY SPEED: (AmInfo precision: +- 0.5% with FastFonts!) -------------- <<< NOTE : The system 2.0 & 32-bits RAM Chips may modify the result >>> KCS Pc Board : 1215 Characters/secs PC AT A2286/8Mhz for A2000 : 2000 Characters/secs Atonce 7Mhz (Hercules MDA 8) : 2200 Characters/secs A500/A2000 (Non ECS) : 2560 Characters/secs A500+ : 4192 Characters/secs A3000 ("simple") : 5776 Characters/secs A2000 + 68030 Commodore (*) : 5821 Characters/secs A3000 (ultra fast rams) : 10740 Characters/secs (*) minimum (more fast with kickstart2.0!) All these results are given for example. The Real result may depend of several parameters : Coprocessors , MNU , MPU , 16 or 32 bits RAMs , Cache memory... But this altrough a good start th have an idea of the power of your computer. THANXES: -------- Thanks to every people that write to me. I always read all the letters that come to me, but , because of the number , it becomes more and more display to answer them all... (Should there be someone who can cope with days of more than 24 hours ???). But I read all letters and I make my best to answer... Thanks again to Jean-Pierre VanBostal , Design System and Thibaut Maquet (the translator/debugger/multitasking man) for testing the program on others configurations , and to Marc Alagem for the program's graphic design. For contact , (About Viruses for my (MVK) MasterVirusKiller program, to send to me your AmInfo's speed Characters/Dhrystones results , bugs reports...) , please write to the adresse below: Leclercq Xavier Vieux Chemin d'Ath n°12 B-7548 Warchin BELGIUM
