Both results used to be compareble, so I guess something has affected your second result

Hmm, interesting, I run that benchmark on my ThinkPad T470 with i5-7300U, and got these (comparable) results.

D1:
Microseconds 1 loop: 3.52
Dhrystones / second: 284444
VAX MIPS rating: 161.89

D2:
Microseconds 1 loop: 3.60
Dhrystones / second: 277657
VAX MIPS rating: 158.03

I'll try that once again on my main PC at home, but I run that D2 test multiple times yesterday, and always got the same results.

maybe check power saving options
or leave dosbox running for a while to give some time to warm cpu up ;)
check cpu stats in task manager

Alright, I don't know why, but I rerun that benchmark, and I got comparable result... Or, exactly the same one lol... I don't know, what shenanigans possessed my PC yesterday :D

On both machines I run benchmarks with cycles=max.

DOSBox is made for games. It's more interesting to test it in them. Other tests are additional to that.
Quake and doom were used by me in the signature's theme. Such results can be compared with stats of wide range of real machines.

This one is testing cpu speed, the main problem of dosbox cause there are already dosbox versions with virtualised/accelerated 3D GFX (Direct 3D/OpenGL/Glide)
It is also easy to use and rather reliable and can be performed on real PCs.

Not that there was much reason to test it. More powerful core means more power in dosbox. I just started this thread to get some latest desktop Ryzen (5/7) 3XXX results that are said to be more powerful than intel right now.
