jvm - Performance: greater / smaller than vs not equal to -


i wonder if there difference in performance between

checking if value greater / smaller another

for(int x = 0; x < y; x++); // y > x

and

checking if value not equal another

for(int x = 0; x != y; x++); // y > x

and why?

in addition: if compare zero, there further difference?

it nice if answers consider assebled view on code.

edit: of pointed out difference in performance of course negligible i'm interested in difference on cpu level. operation more complex?

to me it's more question learn / understand technique.

i removed java tag, added accidentally because question meant not based on java, sorry.

you should still clearer, safer , easier understand. these micro-tuning discussions waste of time because

  • they make measurable difference
  • when make difference can change if use different jvm, or processor. i.e. without warning.

note: machine generated can change processor or jvm, looking not helpful in cases, if familiar assembly code.

what much, more important maintainability of software.
