If two bit-identical computers perform the same actions but in different orders, will they remain bit-identical?

Consider two computers, one a bit-for-bit clone of the other. If I then perform any two arbitrary actions on machine A- like change the volume, then open a chrome browser, then do the same on computer B, but in reverse order, will the computers’ state still be bit-for-bit identical (ram, disc, etc.)? The actions can of course also be more significant ones, like updating an application or driver.

Diving a bit deeper, I’m trying to figure out if the two machines…

  • will always be in different states
  • will almost always be in different states, but there are special cases that are identical
  • can plausibly be either, but its impossible to tell without knowing the two exact actions
