By right, nothing changes. Shutter speed, aperture and ISO remain the same provided the metering bias remain the same. But of course you'll notice that some camera underexposes to protect highlights or tends to overexpose to meter for shadows.
Concerning ISO performance, it's all about light gathering ability and efficiency of the sensor. The more dense the sensor, the smaller the pixels and smaller pixels with smaller surface area have less light gathering efficiency and this translates to noise.
i mean, i post 2nd time because MichealJohn need "brain" whole statement so i re-write the whole thing more clear lor.
thanks for answer anyway.

ehh i already directly answer your question!
the answer is no

the camera metering system will select the
same shutter speed no matter new/old sensor or FX/DX sensor (assume fixed aperture, fixed ISO, fixed lighting condition, fixed metering mode). the
only difference is the amount of noise. in fact, at lower ISO (e.g. 200, 400) there's no difference at all
your last post last line is very confusing, so i thought that is your guessing only

sifu correct me if im wrong. no experience using FF body

-----------------------------------
then ISO same value , shutter speed maintain same speed under fixed aperture...
then DX vs FX format also maintain same shutter speed rate too?
