That's right: the Radeon RX 580 8GB isn't new by any meaningful measure. It's an updated version of last year's Radeon RX 480, based on the same Ellesmere GPU under AMD's Polaris umbrella. If your memory of last June's launch is a little hazy, our AMD Radeon RX 480 8GB Review covers the architecture in detail. It predates Nvidia's response, though, so let's get caught up with the state of mainstream gaming in 2017.
A couple of weeks after AMD debuted its RX 480, Nvidia followed up with GeForce GTX 1060 6GB, which outperformed Polaris in most of our benchmark suite. But it was also more expensive. And as time went on, a wider selection of DirectX 12 games showed that Nvidia's advantage really only applied to DirectX 11. These days, Radeon RX 480 8GB and GeForce GTX 1060 6GB are priced fairly competitively to reflect the fact that they trade blows, depending on what you play.
AMD wants something a little more decisive, though. So it's turning up the core clock on Ellesmere, dialing its starting price to $230, and slapping a new name on the tweaked configuration: Radeon RX 580. This is a familiar move from AMD's playbook. Old favorites like the 2012-era Pitcairn GPU span as many as four generations of Radeon products, after all.

The question now is whether Radeon RX 580 changes the narrative in any way. Does the performance, pricing, and power of "Polaris, Enhanced" strike hard at Nvidia's GP106 processor, or does it only serve to obfuscate the mainstream market with a new name on something old?
AMD didn't bother with a new reference design this time around, and the old one wasn't suitable for RX 580 due to issues we exposed in our Radeon RX 480 launch story and follow-up coverage. Instead, AMD's partners were tasked with designing their own Radeon RX 580s and sending out overclocked versions for sampling ahead of launch. In response, we set aside our reference boards and sought out factory-overclocked models of competing products to compare.
Sapphire Nitro+ Radeon RX 580 Limited Edition
The Tom's Hardware U.S. and German labs received Sapphire's Nitro+ Radeon RX 580 Limited Edition card. It boasts two BIOSes with different clock rates: one sets an ambitious 1450 MHz boost clock and 1411 MHz silent mode, while the other employs a 1411 MHz boost frequency and 1340 MHz silent mode. All of our performance, power, temperature, and acoustic measurements are taken at the 1450 MHz setting, though that latter configuration is in line with what you'll see from most other partner boards.
Consequently, our launch coverage of Radeon RX 580 is more a review of Sapphire's specific implementation than an evaluation of Ellesmere, revamped. But it should still address what AMD's "new" cards are capable of. Don't expect to find this board anywhere near AMD's $230 starting price. Rather, we're told the aggressively-overclocked model will sell for $275, making it the priciest RX 580 at launch time.
The diagram below illustrates Sapphire's design. It's quite a bit different than the Nitro+ Radeon RX 480 that precedes it.
From the outside, this card's understated appearance is neither gaudy nor cheap-looking. It's classy, but not plain. The plastic fan shroud resembles polished metal. Once you touch it, though, the cover's composition is immediately apparent.
On the other hand, Sapphire's sturdy backplate is made of metal. It's also quite a bit flashier with a clean mix of black, grey, and aluminum.
The Nitro+'s length, from the outer edge of its slot bracket to the end of the cooler, is 26.2cm. Its height, from the motherboard slot's top edge to the cooler's protruding heat pipes, is 13.2cm. A depth of 3.5cm makes this a medium-size dual-slot card. Roughly 0.5cm of the depth measurement is attributable to that backplate though, which could affect compatibility with large CPU coolers or mini-ITX-based form factors.
Two 8mm heat pipes made of nickel-plated composite material, an illuminated Sapphire logo, and two power connectors (one eight- and one six-pin) are visible from above the card.
Underneath, you get a good look at Sapphire's heat sink and the thermal solution's two 6mm heat pipes. We also catch a glimpse of the sink responsible for drawing heat away from the MOSFETs.
The cooler’s fins are arranged horizontally, and the end of the card is open to promote air flow. There should be some ventilation possible through the slot bracket as well. Unfortunately, only one small area allows air to escape. The rest of the bracket is monopolized by display outputs, including a big DVI-D port that's slowly going out of vogue.
Interestingly, Sapphire deploys two HDMI 2.0 connectors, likely a nod to enthusiasts with VR headsets, and a pair of DisplayPort 1.4-ready outputs.
Test System and Methodology
We introduced our new test system and methodology in How We Test Graphics Cards. If you'd like more detail about our general approach, check that piece out.
Specifically, for this review, we split testing between our U.S. (performance) and German (power, acoustics, thermal) labs. As mentioned, we set aside our reference-class boards in favor of factory-overclocked models that better represent today's selection of available products. After experimenting with the Windows 10 Creators Update, we were forced to uninstall it after discovering compatibility issues between several games and our measurement software. We're working to address this. However, all results are generated using the latest drivers, including AMD's Crimson ReLive Edition 17.4.2 package, the 500-series press driver, and Nvidia's 381.65 Game-Ready driver.
Special thanks goes to AMD for ensuring our two labs received the same hardware for evaluation, Gigabyte for replacing our Founders Edition card with its GeForce GTX 1060 G1 Gaming 6G, and MSI for replacing our AMD Radeon RX 480 8GB with its own Radeon RX 480 Armor 8G OC.
