Sapphire Nitro R9 390 8GB

Now that we've gone over specifications and numbers of the 300-series GPUs, let's dive into the actual graphics card we have on the test bench today: the Sapphire Nitro R9 390 8GB.

This is the first card from Sapphire that uses the new Nitro brand and takes the mandate from the company to build a card for gamers that is affordable, reliable and simple to understand, while maintaining the performance that you would expect from the GPU in question. A look at the card's aftermarket cooler makes it clear that it's going to get the job done – in my testing the GPU never crossed above 68C even during extended game play sessions. That's impressive for any retail card but it does so while being quiet as well.

For power delivery Sapphire has included a pair of 8-pin PCIe power connectors that are able to provide more than enough juice for a GPU with a 275 watt rated TDP. The connectors are rotated 180 degrees with the clips on the back of the card to help make installation and removal easier with the size of the heatsink Sapphire has strapped on here.

Interestingly, with this release Sapphire has gone with a DVI, HDMI and triple DisplayPort connection configuration. This is identical to what NVIDIA has done with for the last couple of card generations and I do think this is the right balance. Because Sapphire is not using a blower style cooler, the small outlet area on the back panel isn't a concern.

Turning this card over you see the PCB design itself, still crowded even with all 8GB of memory placed on the front, under the heatsink. At the end of the board you'll notice that Sapphire has extended the cooler beyond the board taking total card length to 12.1 inches or 308 mm.

There is no back plate on the Nitro cards, and when I asked Sapphire about this they essentially brought it down to cost. Sapphire knows that adding a back plate is functionally for stiffening the PCB but they were able to do that by increasing the points of contact for the heatsink shroud to the board itself, keeping the card rigid without adding more cost. For those of you that want a back plate for looks and style…sorry!

The cooler that Sapphire has installed is beefy with three heatpipes and three fans. They have integrated a new fan profile as well that allows the fans to stop spinning completely under low workloads; this has been a popular trend in recent months in order to facilitate silent gaming options.

A quick teardown of the card reveals sixteen 512MB DRAMs on the board (clearly you can see the physical advantages of HBM now!) to supply all 8GB of memory than the Nitro R9 390 offers.

Here's a close of up the new Hawaii / Grenada GPU; looks familiar, no? Sapphire spent some time making this PCB as high quality as they could including Black Diamond Chokes and going with 16K rated capacitors on each and every Nitro graphics card.

Overall I think the design and direction that Sapphire has gone with the Nitro series seems to be on point – design a card for "gamers" that doesn't add extra cost but still provides great cooling and capability in the design.
