Graphics Card with different name?

[Wohaaa]

Recently was looking to buy a new GPU for my brother. Found a shop with used hardware and really really cheap stuff as compared to other shops. An RX 480 and 580 are almost next to each other in performance and the 480 was the much cheaper option. I had taken the computer with me. They put the card in, installed drivers, stress tested, everything worked. Nothing wrong with the card itself. So I bought it. It was an XFX card. I got curious and thought why the cooler on it was different than one found on an XFX 480. None of the coolers I saw online matched. Then I searchedother cooler designs of other RX cards. The Card was an RX 570. Same fans, same design, and to 100% confirm this, the memory bandwidth showed up in GPU-Z as 224GB/s. Both the 480 and 580 have 256GB/s and the 470, 460, and 560 are all lower than 224. The 570 was the ONLY gpu in the rx lineup with the bandwidth speed of 224. I'll talk to the shop about this but I am curious to know, is this rare or is it common? And is there also the possibility that this really is a 480 but somehow has a cooler of a 570? I can't open it as the sticker is on one of the screws.

 

TL;DR:

I bought GPU. Every program shows as RX 480. Physical design is that of XFX RX 570 in every way. Is this possible?

It is possible, considering many brands didnt change the PCB design from 470 to 580. In other words, 4 cards with the same PCB and cooler. After all they are based on the same architecture from the same core (x70 are cut down from the x80 with software). It could also be an RX 570 carrying an RX 480 VBIOS.

 

Does it have 2304 Stream Processors?

I don't know as GPU-Z doesn't show anything called "Stream Processors" however it shows that it has 2304 shaders, if that helps. I'll upload the screenshot from GPU-Z but might take a couple minutes because it's not on the computer im writing this on

thing is, the memory bandwidth difference between x70 and x80 is purely due to lower memory frequency. I'm not sure if this vbios just so happens to have x70 memory clock speed programmed into it.

 

What if you try overclock it? That could help determine whether the silicon is 400 series or 500 series.
