DOSBOX-X and CPU cycles accuracy to real CPU

I noticed that in the online documentation of DOSBOX-X for the CPU speed table, it lists the Pentium II 300 at 200,000 cycles and then under it the Pentium III 866 at 407,000 cycles. That seems like a nearly triple the CPU speed just to get around double the CPU performance and that seems way off. For real hardware (not emulation), is there a situation where a Pentium III 866 is only around twice as fast as a Pentium II 300 in a CPU bound scenario? Also I check out DOSBOX Pure in Batocera, and it still lists the Pentium II 300 at 200,000 cycles but a Pentium III 600 at 500,000 cycles. I believe the 500,000 cycles for the Pentium III 600 (if it's the Coppermine 133 MHz FSB version) in DOSBOX Pure than I do for the 407,000 cycles for the Pentium III 866 in DOSBOX-X, especially since both of these emulators, list the Pentium II 300 as 200,000 cycles. Which is more likely to be closer to realistic if the Pentium II 300 is referenced as 200,000 cycles in both emulators, the Pentium... Read more
