SAPPHIRE debuts NITRO+ Radeon RX 580 Limited Edition for demanding gamers

SAPPHIRE debuts NITRO+ Radeon RX 580 Limited Edition for demanding gamers”

Meanwhile, the teaser video of the AMD Radeon RX Vega GPU has leaked online, giving game enthusiasts and experts a first look at the high-end graphics card. The Radeon RX 550 will be coming later this week, just like the RX 580 and RX 570, and should have a suggest retail price of U.S. $79. In comparison to AMD's previous-generation architecture, Polaris has more powerful geometry processing capabilities, increased buffer sizes, more efficient delta color compression, tweaked memory controllers, asynchronous compute capabilities with prioritization, specialized temporal scheduling, and support for AMD technologies like Radeon Chill, FreeSync (and FreeSync 2), and HEVC and H.265 4K decoding. We know that the RX 580 is a refresh of the RX 480 so there will not be huge boosts in performance but we could get higher clock speeds. These factors combine to allow AMD to run the GPU at higher clock frequencies, with more stable voltage, and in turn gives more performance and higher overclocking potential. The Radeon RX 500 lineup doesn't include the hotly anticipated Vega GPUs, nor are they really new at all.

The lower end RX 570 saw a change in its memory clock speed, which has been increased to 7 Gbps from 6.6 Gbps, unlike the RX 580 that stuck at 8Gbps. The AMD RX 560 features 1024 GPU Cores, a Base clock of 1175 MHz and a Boost clock of 1275 MHz.

The RX 560 and RX 570 are both iterative improvements of the RX 460 and RX 470 GPUs AMD launched almost a year ago.

Much all of the predecessors of the other cards on this list, the RX 570's predecessor is the RX 470. All the products will be available by this week worldwide, save for the RX 560, which will be made available only in May.

At just $189 for our souped-up overclocked version, $20 over the reference model's MSRP, the RX 570 pumps out strong gaming performance at 1080p, averaging 60 frames per second with the quality up to ultra on every game in our test suite save Deus Ex: Mankind Divided, which is to be expected. This should give it a decent boost compared to the Radeon RX 460. But the allure of the RX 500 series is no shinier than the RX400's, so I'm not sure why AMD expects people to suddenly see the light - unless it's counting on its 2017 FOMO marketing tactics.

There won't be any reference versions of the Radeon RX 570 available, only customized cards by AMD's hardware partners. It is literally named "Golden Sample" on the box and has a higher retail price than RX 580 MSRP, coming in at $270 MSRP. There are only a couple of these graphic cards though.

PC World notes that the RX 570 and RX 580 will go on sale starting today.

- Tweaktown.com - Sapphire Radeon RX 580 Nitro+. The Radeon RX 570 Gaming X will boost up to 1280MHz, while the RX 580 Gaming X will boost up to 1395MHz and features 8.1Gb/s memory.
