Sapphire RX550

Hi,

I found this great little card, 1.5 PCI-e slots and there is a 4 GB version. It's not in the RX580 league but did get a great review even for 1080p gaming quite well.

In the review it was mentioned that two cards can be "connected" together but there is no need for a connector cable like in SLI or CROSSFIRE.

I've not SLI'd/CROSSFIRED any GPU's yet - and I read somewhere that this isn't supported (?)

Anyway, if anyone here has used the RX550 or two together please mention any of the above or whether it's worth using two of these together.

Multi-card setups are not worth it.


You will have issues with scaling at all in most games since driver support for it is non-existent in most titles.

Definitely not worth it. You can see for yourself, even if there's 100% scaling (there won't be) :
RX 550 = 512 shaders , 16 ROPs, on 128 bit memory bus with 50W TDP

https://www.techpowerup.com/gpu-spec...n-rx-550.c2947

Let's say you double that, you get 1024 shaders , 32 ROPs, on 256 bit memory bus with 100W TDP which is weaker than a 2048 shader RX 570 8GB in every way because 1024 shaders is only RX 560 level which incidentally is a ~90W part and Crossfire doesn't double memory size.

I haven't mentioned TMUs since they're proportional to shaders for GCN architecture.

In China, AMD is launching the cut down RX 470D again as RX 560XT which will have 1792 shaders , 32 ROPs, on a 256 bit memory bus. That's probably a good option if you're in China, but for everyone else that's on a budget the RX 570 is the card to buy undoubtedly.

There's basically two cards worth buying in AMD's lineup if you have the patience to tune them: RX 570 (~120W-160W TDP BIOs) < $150 and RX Vega 56 (150W-165W TDP reference BIOs , Nitro+ is 180-240W limit) <$350. RX 580 / RX 590 are clocked to the wall so they're power hungry for their performance class , RX Vega 64 and Radeon VII aren't as price competitive as they could be and are also power hungry out of the box.
