PowerColor Red Devil RX 590 Review

PowerColor Red Devil RX 590 Review


Such has been the efforts AMD have put into their Ryzen CPUs – with extraordinary results – the GPU side of their business has been slightly left behind. Development costs are always insane and it would be asking too much of a company to completely revise both elements of their companies portfolio at the same time.

However, the RX 580 was a very attractive mid-range card and a little bit of an upgrade is always welcome. The RX 590, here in PowerColor Red Devil guise, is based upon the same 4th Generation of the GCN Architecture, but with some of the always popular power creep in the form of faster clock speeds and a reduced manufacturing process allowing you to pump yet more Watts to the GPU.

Despite the high end of gaming being all about producing 4K splendour, the reality is that most people still game at the hugely popular 1080P resolution, the target audience for the RX 590. Does it improve upon the RX 580 enough to tempt your wallet?

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, hopefully giving it a boost in performance when compared to the current Radeon 5 series range.
