Message-ID: <1990Jun6.211431.3539@iesd.auc.dk> Date: 6 Jun 90 21:14:31 GMT Sender: sunesen@iesd.auc.dk (Peter Sunesen) Reply-To: sunesen@iesd.auc.dk (Peter Sunesen) Organization: Mathematics & Computer Science, University of Aalborg Lines: 51 I have read some article about, 80486 and that it is running the same speed as a 80386. I can say that the person that is writing this, only not have used a 486 or will say something wrong about it becouse thay not can buy one. I have used a 80486-25, since decenber 1989, and can say that my other Taiwan computer is running about 3 times slower, and it is a 80386-25 with cache. It can be right, that a 80386 is running the same speed as a 80486, but the answer to this is that Harddisk, not is made more quick becouse it is running at a 486. I was having a "verry" quick harddisk 18 ms in acces on the 386, but when I installed it on the 486 it was slow, and was going to wait on the harddisk. So the problem was now that I have speed up the computer but the problem was in fact that I was running more on the harddisk, than on the computer, so the speed rise was not so big, before i put a faster harddisk indsite. But a 486 is not a computer, that the user have to run wordperfect, but to run hevy calculation, and when you do that it is running about 3 times as fast. So juge the 486 on what it is doing and not was the test is saying. 80486-25 8KB cache ------------------ Norton 4.5 : 40.5 Mips : 10.9 80486-33 128KB cache external ----------------------------- Mips : 14.9 About the bus talk, the MCA is just fore IBM, the EISA will be the future becouse you the can speed up for exsample the display adapter / Harddisk controler. But what good it this if for exsample a TRIDENT VGA 512K display adapter must be speedet down to slow and 8bit if there is a slow SEAGATE SCSI adapter on the computer ????. My conclution is that, the ISA/OLD bus will be on long time more, and the Taiwan computers first will produce EISA when the card to the bus is there. So if you out there is buying a 486 with old bus you is not doing somthing wrong, becouse the 486 is fast in all cases, becouse for exsamble the harddisk is a long time behind the computers i acess time, so when harddisk with 1 ms in acess is ther I will definit by EISA, not before. If some person is on way to buy a 80486, I can give a adress on a company in Taiwan were I have good experiance, just E-mail me. Peter Sunesen sunesen@iesd.auc.dk Tlf: +45 98114268 Fax: +45 98114268
