The RX 580 was running fine but I don't use a lot of GPU so I decided to swap it for the Sapphire Pulse Radeon RX 550 4GB, it is half the price.
This card appears to be running fine too.
Monitoring it with the
radeontop utility, I'm using 2.5GB of VRAM while driving two screens, one is 4K and the other is 1920x1200
As it is really cheap, I think this card is useful as a spare or for people who don't use GPU-intensive workloads.
The card is less than 2 PCIe slots width so it is an interesting choice for people who are using both slots on a Blackbird.
The sensors command tells me the fan is running at 1231 RPM idle, it is a bit faster than the fans on the RX 580. I feel it may make just a little bit more noise compared to an idle RX 580 which has two fans that appear to be bigger and quieter.
I may decide to return this one as well and swap it for the Big Navi in November or maybe I will get a Big Navi and keep this as a spare.
My only real concern then is the fan noise, some people may want to pay that little bit more to get a more silent alternative.
