Earlier this month Sapphire announced a new budget-oriented series of graphics cards it calls PULSE. The new series slides in below the premium Nitro+ series to offer cheaper graphics cards that retain many of the high-quality hardware components but lack the flashy extras on the coolers, come in at lower factory overclocks, and have fewer PCI-E power inputs which, in theory, means lower overclocking headroom. The new graphics cards series is currently made up of five Polaris-based GPUs: the Sapphire Pulse RX 580, RX 570, RX 570 ITX, and RX 550.
According to Sapphire, Pulse graphics cards use many of the high-end components as the Nitro+ cards including Black Diamond Chokes 4, long lasting capacitors, fuse protection. And intelligent fan control. The new graphics cards have aluminum backplates, removeable Quick Connect fans with semi-passive cooling technology that allows the fans to turn off when the card is under light load. The RX 580 and RX 570 use Dual-X coolers and the RX 570 ITX and RX 550 use single fan shrouded coolers.
Compared to Nitro+, the coolers are a bit less flashy and there are no Nitro+ Glow LEDs. If you are not a fan of bling or do not have a windowed case, the Pulse cards might save you a bit of money while getting you most of the performance if Sapphire’s claims are accurate.
Speaking of performance, the Pulse branded graphics cards are factory overclocked, just not as much. The Sapphire Pulse RX 580 with its 2,304 cores comes with a boost clock of 1366 MHz, the RX 570 and RX 570 ITX come with GPU boost clocks of 1,284 MHz and 1,244 MHz respectively, and the RX 550 has a boost clock of 1,206 MHz. Memory clocks sit at 8,000 MHz for the RX 580 and 7,000 MHz for the remaining Pulse cards (RX 570, RX 570 ITX, and RX 550).
Along with the introduction of its new Pulse series of graphics cards, Sapphire has entered a “strategic partnership” with motherboard manufacturer Asrock. The new graphics cards are shipping now and will be available at retailers shortly. Pricing for the RX 550 isn’t available, but prices for the other cards has appeared online as follows: Pulse RX 580 8GB for $229.99, Pulse RX 580 4GB for $199.99, Pulse RX 570 for $179.99, Pulse RX 570 ITX for $169.99.
In all, the Pulse cards appear to be about $20 cheaper than the Nitro+ variant. We will have to wait and see if those prices hold up once retailers get stock in.

Phoronix have had a chance to test out the refreshed Polaris RX 580 on the Linux 4.11 kernel and Mesa 17.1-devel, initially the AMDGPU-PRO 17.10 driver update was not included thanks to interesting timing. The performance deltas are as you would expect, a slight increase in performance that is relative to the increased clock speeds, just as when run on Windows. They also had a chance to try overclocking the new card, AMD added support for overclocking GCN 1.2 and newer cards on their proprietary Linux driver in 2016. They managed to increase the core by 6% without running into stability issues however when they overclocked the memory, they saw serious performance decreases. Check out the steps they tried along with the results from the overlocked GPU here.
"Yesterday I posted the initial Radeon RX 580 Linux benchmarks while now with having more time with this "Polaris Evolved" card I've been able to try out a bit more, like the AMDGPU Linux overclocking support. Here are the ups and downs of overclocking the Radeon graphics card under Linux."

Ryan covered the improvements over the previous Polaris based cards the RX 580 offers, a higher Rated Clock and standardizing memory frequency of all RX 580 models to 8GHz. That lead to the expected increase in performance compared the the RX 480, in a marketplace somewhat different than what the first Polaris chips arrived in. Consumers now know what NVIDIA's current generation cards provide in performance and prices have settled as much as can be expected in the volatile GPU market. Those using cards several generations old may be more receptive to an upgrade than they were with the previous generation, especially as the next large launches are some time off; we shall see if this is true in the coming months.
One particular reason to consider upgrading is VR support, something [H]ard|OCP covers in their review. The improved speeds do not provide miracles in their VR Leaderboard however they do show improvements in some games such as Serious Sam, with reprojection rates dropping markedly.
"AMD is launching the AMD Radeon RX 500 series today, and we lead with a custom retail Radeon RX 580 GPU based video card from PowerColor. We’ll take the Red Devil RX 580 Golden Sample video card through the paces and see how it compares to the competition at the same price point."

What is old is new again
Trust me on this one – AMD is aware that launching the RX 500-series of graphics cards, including the RX 580 we are reviewing today, is an uphill battle. Besides battling the sounds on the hills that whisper “reeebbrraannndd” AMD needs to work with its own board partners to offer up total solutions that compete well with NVIDIA’s stronghold on the majority of the market. Just putting out the Radeon RX 580 and RX 570 cards with same coolers and specs as the RX 400-series would be a recipe for ridicule. AMD is aware and is being surprisingly proactive in its story telling the consumer and the media.
- If you already own a Radeon RX 400-series card, the RX 500-series is not expected to be an upgrade path for you.
- The Radeon RX 500-series is NOT based on Vega. Polaris here everyone.
- Target users are those with Radeon R9 380 class cards and older – Polaris is still meant as an upgrade for that very large user base.
The story that is being told is compelling; more than you might expect. With more than 500 million gamers using graphics cards two years or older, based on Steam survey data, there is a HUGE audience that would benefit from an RX 580 graphics card upgrade. Older cards may lack support for FreeSync, HDR, higher refresh rate HDMI output and hardware encode/decode support for 4K resolution content. And while the GeForce GTX 1060 family would also meet that criteria, AMD wants to make the case that the Radeon family is the way to go.
The Radeon RX 500-series is based on the same Polaris architecture as the RX 400-series, though AMD would tell us that the technology has been refined since initial launch. More time with the 14nm FinFET process technology has given the fab facility, and AMD, some opportunities to refine. This gives the new GPUs the ability to scale to higher clocks than they could before (though not without the cost of additional power draw). AMD has tweaked multi-monitor efficiency modes, allowing idle power consumption to drop a handful of watts thanks to a tweaked pixel clock.
Maybe the most substantial change with this RX 580 release is the unleashing of any kind of power consumption constraints for the board partners. The Radeon RX 480 launch was marred with issues surrounding the amount of power AMD claimed the boards would use compared to how much they DID use. This time around, all RX 580 graphics cards will ship with AT LEAST an 8-pin power connector, opening overclocked models to use as much as 225 watts. Some cards will have an 8+6-pin configuration to go even higher. Considering the RX 480 launched with a supposed 150 watt TDP (that it never lived up to), that’s quite an increase.
AMD is hoping to convince gamers that Radeon Chill is a good solution to help some specific instances of excessive power draw. Recent drivers have added support for games like League of Legends and DOTA 2, adding to The Witcher 3, Dues Ex: Mankind Divided and more. I will freely admit that while the technology behind Chill sounds impressive, I don’t have the experience with it yet to claim or counterclaim its supposed advantages…without sacrificing user experience.

Tagged: video card, RX 580, RX 570, RX 560, RX 550, rx 480, rumor, report, rebrand, radeon, graphics, gpu, amd
According to a report from VideoCardz.com we can expect AMD Radeon RX 500-series graphics cards next month, with an April 4th launch of the RX 580 and RX 570, and subsequent RX 560/550 launch on April 11. The bad news? According to the report "all cards, except RX 550, are most likely rebranded from Radeon RX 400 series".
Until official confirmation on specs arrive, this is still speculative; however, if Vega is not ready for an April launch and AMD will indeed be refreshing their Radeon lineup, an R9 300-series speed bump/rebrand is not out of the realm of possibility. VideoCardz offers (unconfirmed, at this point) specs of the upcoming RX 500-series cards, with RX 400 numbers for comparison:

The first graph shows the increased GPU boost clock speed of ~1340 MHz for the rumored RX 580, with the existing RX 480 clocked at 1266 MHz. Both would be Polaris 10 GPUs with otherwise identical specs. The same largely holds for the rumored specs on the RX 570, though this GPU would presumably be shipping with faster memory clocks as well. On the RX 560 side, however, the Polaris 11 powered replacement for the RX 460 might be based on the 1024-core variant we have seen from the Chinese market.

No specifics on the RX 550 are yet known, which VideoCardz says "is most likely equipped with Polaris 12, a new low-end GPU". These rumors come via heise.de (German language), who state that those "hoping for Vega-card will be disappointed - the cards are intended to be rebrands with known GPUs". We will have to wait until next month to know for sure, but even if this is the case, expect faster clocks and better performance for the same money.
