XFX RX590 Fatboy Review

Introduction

Next up in our brace of RX 590 reviews is the XFX RX 590 Fatboy.

We’re struggling to think of a card that has come with such a strange name. It would be like calling a card a lard arse. However, names are temporary and forgettable, as long as the performance is there nobody will give two hoots about its subtitle. We did prefer the Dual Dissipation name of old XFX cards though.

So far we’ve seen that the RX 590 is a bit better than the RX 580 and the GTX 1060, giving performance akin to a theoretical GTX 1065. How does the XFX take upon this new Radeon card compare to the PowerColor Red Devil version? Let’s find out.

Technical Specifications

As you can see, the RX 590 is largely a faster version of the RX 580, with the reduction in process from the 14nm of the old RX 580 to the smaller 12nm of the RX 590 enabling higher clock speeds and more power to be fed to the card. Like the PowerColor the XFX Fatboy comes equipped with a factory overclock.
