Sapphire Nitro+ Radeon RX 64 Limited Edition review: Taming Vega’s flaws with brute force

dsc3167

Four long months after AMD’s flawed Radeon Vega graphics cards launched, custom versions are finally starting to trickle out—and the wait was worth it. The monstrous, yet luxurious Sapphire Nitro+ Radeon RX 64 Limited Edition relies on brute force to squash the most troubling problems that plague reference Vega cards. This beast sports the most wildly effective cooler to ever cross our test bench, and it manages to toss in a factory overclock while providing impressive tools for enthusiasts to push performance even further.

Curing Vega 64’s terrible heat and noise requires tradeoffs, though. Keeping the Sapphire Nitro+ Radeon RX 64 Limited Edition cool and quiet requires an awful lot of metal—and an awful lot of power. Then there’s the cost: At $659, this card is priced closer to a GeForce GTX 1080 Ti than Vega’s traditional rival, the GTX 1080. Is it worth the premium?

Let’s dig in.

Sapphire Nitro+ Radeon RX 64 Limited Edition specs and features

Like most custom graphics cards, the Sapphire Nitro+ Radeon RX 64 Limited Edition puts its own unique spin on things, but shares many of the same tech specs as the reference GPU. Here’s a look at the core Radeon Vega tech specs before we examine Sapphire’s own tweaks.

Usually we kick off a graphics card review with a discussion about the tech specs but that’s not what’s most noteworthy about this card—instead, it’s the sheer size of the custom cooling solution. It’s hard to tell in these pictures but the Sapphire Nitro+ Radeon RX 64 Limited Edition is an absolute monster of a graphics card, dwarfing traditional two-slot designs in every dimension. This beast goes three slots deep, 4.75-inches wide, and 12.25-inches long. It’s big. By comparison, AMD’s Radeon RX 64 reference card sports a two-slot design that’s 3.75-inches wide and 10.5-inches long.

The Nitro+ Limited Edition is so massive, in fact, that Sapphire ships it with a nicely constructed GPU support bracket to keep the card from sagging in your case. The black nickel-plated bracket doesn’t demand any precious additional PCIe slots, unlike some aftermarket GPU supports, and it complements the look of Sapphire’s Nitro branding. The company plans to sell it separately as well.
