Help.. I have just changed my CPU from a Cyrix 6x86 P166+ to an AMD K6 166MHz, and have noticed a drop in performance with programmes written using using DJGPP and Allegro. The drop in performance is in the region of 20%. I have benchmarked the AMD and the Cyrix using Wintune 97, and in all the tests the AMD is faster than the Cyrix. eg: Floating Point Performance (MFLOPS) ------------------------------------------------------- AMD K6 P166 98 Cyrix 6x86 P166+ 52 Integer Performance (MIPS) ----------------------------------------- AMD K6 P166 320 Cyrix 6x86 P166+ 250 Does anyone have any ideas as to the cause of the performance drop with the AMD CPU ?
