GPU based on a 12 nm FinFET manufacturing process. I did a full review of it while testing the XFX RX590 Fatboy, you can check that out HERE. Well in an accidental set of circumstances I ended up with two matching cards. Normally I patch together Crossfire or Multi-GPU testing with two different cards. Well, I spent the rest of the day yesterday after everything went live testing out the XFX RX590 Fatboy in our same tests only with both cards running. As always these results depend a lot on the games that you play but I was curious how things would work out with our test suite. Like our previous Crossfire and SLI coverage, the commenting will be at a minimum and this is just a quick article to show off the numbers so keep that in mind and use the information however you would like.
