Sapphire Radeon RX Vega 64 Nitro+, AMD’s VEGA Architecture with Factory-Overclocked Performance

Sapphire Radeon RX Vega 64 Nitro+, AMD’s VEGA Architecture with Factory-Overclocked Performance

The Sapphire Radeon RX Vega 64 Nitro+ card features world of extreme gaming with high resolution, high refresh-rate displays and virtual reality headsets. The graphics card comes factory-overclocked, achieving up to 7% better framerate compared to reference cards.

The combination of custom and aftermarket heat sink combine to create an almost-1.6kg behemoth. Wisely, Sapphire bundles a bracket to keep a sagging card from tugging on your PCI Express slow. Measuring 31cm long, 13cm tall, and 4.8cm deep, this is technically a 2.5-slot card that ties up three slots worth of expansion on your motherboard. Additionally, a plate tacked on to the back side ties up another 0.5cm, meaning you’ll need to leave room behind the Radeon RX Vega 64 Nitro+, too.

Dropping this card into your first motherboard slot may consequently result in a tight fit. You’ll want to be careful with its height too, since the 13cm measurement doesn’t take into account another 3cm or so for cables that stick straight out from the top. The Sapphire logo under the backplate features RGB lighting, meaning it can be color-coordinated or switched off altogether. Sapphire includes the requisite software for blinging its board out. As you can see, the interface is fairly straightforward.

The fan shroud is made of black plastic. There are two transparent rings around the larger fans, which sandwich a smaller one in the middle. Without power, this looks a little strange. But that changes once the card roars to life and Sapphire’s RGB lighting makes its presence known. By default, you’re greeted by a bright blue hue.

Up top, the card is dominated by no fewer than three eight-pin auxiliary power connectors and a back-lit Sapphire logo. Again, the standard setting is bright blue. Choosing any other color requires Sapphire’s software. Similar to AMD’s reference Vega 64 cards, Sapphire implements a switch that lets you choose between two BIOS versions. The secondary build facilitates significantly lower power consumption, making the card quieter, cooler, and inevitably slower. Combined with WattMan’s three modes, which are Turbo (maximum power limit), Balanced (default), and Power Saver (minimum power limit), you have access to six different combinations.

Looking at Sapphire’s Radeon RX Vega 64 Nitro+ from the side reveals vertically-oriented heat sink fins that are bent a above the GPU. This guides airflow a , and increases the surface area for cooling. The back end is all but closed due to those vertical fins. At the other end, a slot bracket hosts three DisplayPort 1.4-ready outputs and one HDMI 2.0 connector. There is no DVI-I connectivity, leaving more room for ventilation. Unfortunately, the way Sapphire positioned its heat sink fins, there is no real flow out the back. Instead, heated air exhausts down, toward your motherboard, and up, back into your case.
