- From a beginner...
-
- I wrote a short program in assembler to write to every pixel on
- Date: Thu, 20 Aug 1992 13:18:29 GMT
- Lines: 13
-
- On my 386/33 with Trident 8900 chip the program takes 1:10
- minutes.
-
- On my 486/33 with identical video board the program takes 11:46
- minutes.
-
- Could someone please give me a hint why the 486 is 11 times
- slower than the 386.
-
- Using another program that did a simple INC AX,1 repeatedly,
- the 486 was 2.8 times faster than the 386.
