Card Specifications

The AMD Radeon R9 390X is nothing really new, it's a rebranding of the Radeon R9 290X with the same Hawaii-based GPU that was released in October 2013. What AMD has done with it, is a couple of tweaks here and there, which we've compared an R9 290X 8GB card in our benchmarks specifically.

We have a 28nm-based Hawaii GPU with 2816 stream processors, 64 ROPs, and 176 TMUs. AMD has kept the 512-bit wide memory bus, and SAPPHIRE has set the 8GB of GDDR5 VRAM clocked at 6GHz. This provides a performance benefit of around 5-10% on average when compared to the older R9 290X.

Cooling Setup

SAPPHIRE has used its triple-fan Tri-X cooling technology with three 80mm cooling fans keeping the Tri-X R9 390X cool. SAPPHIRE has achieved some engineering finesse with the product, so it doesn't just perform great, it also looks beautiful, too.

SAPPHIRE has used the latest version of its Tri-X cooler, something that now includes dual ball bearings in each of the three fans, as well as an enhanced Intelligent Fan Control, which will turn the fans off when they're not needed for a completely silent card. SAPPHIRE has also used its impressive Black Diamond chokes, which will provide the Tri-X R9 390X 8GB with excellent performance with increased reliability.


Starting at the front of the card, we can see the three 80mm fans that make up the Tri-X cooling. Underneath and behind the middle fan, we can see the three heat pipes and two large, but separate heat sinks that are keeping the entire GPU, VRAM and VRMs cool.


Another look at the Tri-X R9 390X, where you can see the separation of the heat sinks: two separate heat sinks keeping two parts of the card cool.


A closer look at the heat sink that is keeping the VRMs nice and cool, something that the Radeon R9 Fury X won't have to worry about thanks to it being powered by High Bandwidth Memory (HBM).


To the left, we have the aluminum fin array that keeps the GPU itself cool, while a vapor chambered contact plate fills out the rest of the card.
