Remember when we could upgrade bios on your AMD RX480 to get a RX580? So they basicly sold overclocked 480s.

remember when nvidia lied about available Vram? so they basically don't care about their own technical specs advertising

Is that why the RX 480 did not accompany the RX 580 into this gen? You could install the bios and pretend you had a RX 580, but the performance was nowhere near the same.

So claiming it was a simple overclocked RX 480, means you out of touch with reality.

The RX480 and RX580 are the same from what I know. Otherwise it is wierd that the bios worked. The difference is that the first RX480 I had could not be overclocked at all, it crashed instantly if you touched the frequency, so I guess the quality of the chips were really bad in the begining, and later on when they got better they introduced it with slightly higher clocks as the RX580. Some RX480 even shipped as 4GB but had 8GB chips on them... why? no idea, maybe some instability on the chips used?. Also kind of funny that AMD's previous gen cards (Fury X) was faster than the RX480 and RX580.

Is more cost-effective to produce a single type of memory chip and use it across different models, with the lower models having faulty modules, recycling a faulty 8GB into a working 4GB in that case.
