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.
We've used the word 'unique' a few times now to explain the look and style of the HIS Radeon R9 390X IceQ X2, so now we'll talk in detail about the cooling system that HIS has deployed onto this card.
Another look at the front of the card, where HIS has used some larger 89mm axial fans, keeping in line with the dual-slot design. The cooler has a single gigantic heat sink that has five heat pipes pumping into it, with three of them being 6mm, and two of them being 8mm.
That big aluminum heat sink, in much greater detail - this is the tail end of the card.
Here we can see the bottom of the card, with a tease of some of the heat pipes running through the HIS Radeon R9 390X IceQ X2.
You can see that the backplate extends up and over the card, and while most people probably won't know what this is for, I think HIS have put this in place so that when you reach for the card inside of your PC, you're not going to burn yourself on some seriously hot heat pipes; especially after a huge benchmarking or gaming session.
