SAPPHIRE Nitro+ Radeon RX 590 Particular Version – Polaris Rides Once more.

What Is The RX 590

Polaris 30, the RX 590 is Polaris 30 in the simplest of descriptions.  However what does that imply? Nicely, first off with what it isn’t.  The RX 590 just isn’t a bigger Compute Unit rely variant of the RX 480/580 because it nonetheless carries 2304 Stream Processors.  Reminiscence configuration stays the identical with 8GB of GDDR5, no G5X right here however they did prohibit the RX 590 to solely being made in 8GB variants so no 4GB mannequin available.  So, what’s the massive fuss? Manufacturing course of change has prompted a brand new mannequin, the RX 480/580 was made on GlobalFoundries 14nm course of nodes whereas the RX 590 is made on their 12nm node (which by design allowed AMD to maneuver the prevailing 14nm designs over with out redesign because of being the identical optical dimension).   Transferring to the 12nm node allowed for a bit extra headroom on the clock and energy effectivity, which we’ll check out later in additional element.  They might have bumped the TDP of the RX 590 as much as 225w however in doing so that they’ve allowed for a considerably larger core frequency of nicely over 1500MHz which was what solely the most effective of the most effective Polaris 20 chips may do permitting for over 7 TFLOPS  of peak compute efficiency out of the field.  Whereas I nonetheless would have most popular to see this card get a nomenclature extra akin to a RX 580+ or RX 585 for the reason that core specs outdoors of node, energy, and clock speeds have stayed unchanged I believe we’ll discover that the RX 590 is a welcome addition to the Polaris household nonetheless.

SAPPHIRE Nitro + Therapy

One thing main to get out of the way in which, if the SAPPHIRE Nitro+ RX 590 appears to be like acquainted in design then you definitely’re not loopy.  This card retains the core design from the RX 500 collection, and that’s an excellent factor.  After we took a have a look at the RX 570 at launch we discovered the construct of the cardboard to be completely great.  The RX 590 is not any exception to this.

The SAPPHIRE Nitro+ RX 590 Particular Version get’s the stable Four heatpipe design with 2x8mm and 2x6mm heatpipes snaking although the complete dimension heasink saved cool by a pair of blue lit twin ball bearing followers that make up the Twin X cooling answer.  Being designed for 300w of cooling this setup has no bother taming the brand new larger TDP Polaris 30 chip as you’ll see additional down.

Energy design is dealt with by 6 section 50amp board design together with Black Diamond Chokes and polymer capacitors as earlier than with the preview 500 collection Nitro+ board design with the identical 8+6pin energy connections which are inverted for ease of set up and elimination.

The included Twin Bios (want everybody did this) offers you the default choices of Nitro Enhance settings or Silent Settings, though it’s so quiet already unsure the silent settings is required outdoors of maybe decreased energy consumption.

The I/O of 1 DVI-D, 2xDP 1.4,  and 2xHDMI ports together with the heatsink shroud and backplate mirror that of the Nitro+ RX 570 and 580, however this time with the Elvis loving Metallic Blue.  I’m going out on a limb right here and saying that the colour is perhaps a flip off for lots of people who would a lot somewhat have seen this card launch with the identical, and even make it metallic, black shroud and backplate design as earlier than.  I get they needed to distinguish this mannequin, and whereas it does look good on it’s personal I don’t see many builds this trying proper at residence in.

Testing Methodology

The entire testing was performed on our Intel Z370 take a look at bench powered by a 5GHz Core i5 8600Ok.  We ran all assessments involving DX11 by means of three paces and averaged the outcomes of all metrics to come back to the ultimate numbers.  For DX12 and Vulkan we used the newest launch of OCAT on the time and ran the ensuing file although our algorithm that extracts the metrics for measurement.  The outcomes are offered as Avgerage FPS that characterize the place the common body fee fell over the course of the take a look at, 1% Low which represents the bottom 1% of frames, after which the .1% low represents the underside .1% frames.  These metrics give a greater understanding of general efficiency somewhat than representing absolutely the minimal body fee as that would doubtlessly be a random outlier, however know that the .1% can nonetheless be effected by asset loading throughout runs.

We’re evaluating the RX 590 to the GTX 1060 6GB FE and the Radeon RX 480 8GB at the moment.  Whereas there might be some who’re bitter in regards to the absence of the RX 580, and that’s comprehensible, we’re taking a look at the place this card performs in relation to baseline metrics.  The RX 480 8GB is consultant of when Polaris hit the market and might present us an excellent then and now comparability with out lots of extras surrounding it, and the GTX 1060 6GB FE serves as a stable baseline metric for 1060 efficiency.

1080p Outcomes

The Radeon RX 590 is marketed as the final word 1080p gaming card.  Whereas I’m positive there are lots of that will argue the GTX 1070 or the Vega 56 would fortunately take that place these playing cards had been designed and marketed to the 1440p gamer. At 1080p the RX 590 completely dominates the earlier Polaris GPU and walks away with a stable efficiency lead over the GTX 1060 6GB FE, even comes near matching it in Murderer’s Creed Odyssey which is stunning on account of NVIDIAs dominance in that title throughout all tiers.  The SAPPHIRE Nitro+ RX 590 noticed zero core frequency fluctuations by means of all these assessments, it maintained it’s full 1560MHz core clock always.

1440p Outcomes

The RX 590, very like the RX 480 8GB can be marketed as being 1440p succesful.  I discovered in early testing of the RX 480 that it was in a position to sport at 1440p however with a bit extra compromises than I actually needed to take for my private gaming expertise.  So with the added beefcake of the RX 590 I used to be actually hoping to see the 1440p gamer a bit extra glad, however nonetheless got here up only a bit shy.  It’s nonetheless a way more preferable expertise than the playing cards it’s lined up in opposition to at the moment.  I’d see it comfortably powering alongside 1440p gaming at Medium settings and paired with a Freesync show delivering on that 1440p functionality. The SAPPHIRE Nitro+ RX 590 noticed zero core frequency fluctuations by means of all these assessments, it maintained it’s full 1560MHz core clock always.

Synthetics, Energy, And Thermals

Over time I’ve come to restrict my artificial assessments as they’re merely not that indicative of gaming efficiency however nonetheless server as an excellent identifier of how playing cards distance themselves in uncooked energy figures.

The Twin X cooler on the SAPPHIRE Nitro+ RX 590 is at it’s greatest while you give all of it it may possibly take.  Each the thermal and energy draw numbers beneath had been taken after 30 minutes of looping the 3DMark Firestrike Mixed Check.  This gave the cardboard sufficient time to equalize on thermals, core clock, and energy draw.  I need to reiterate that by means of these assessments The SAPPHIRE Nitro+ RX 590 noticed zero core frequency fluctuations by means of all these assessments, it maintained it’s full 1560MHz core clock always.

Undervolting Explored

For the reason that launch of the RX 480 we discovered that Radeon playing cards benefited vastly from undervolting.  In truth they tended to learn extra from this than overclocking by way of general efficiency.  So somewhat than specializing in overclocking efficiency we needed to see how efficiency, energy, and thermals reacted when wonderful tuning the Polaris 30 GPU.  We did this in a couple of methods beginning with taking our baseline efficiency from earlier.  Then we undervolted the P states right down to once they crashed at 1050mV then bumped them as much as 1075mV for stability and decreased the ability restrict to -10% as any decrease would trigger the clock fee to dip from time to time. The to see the place the RX 590 could be general if it matched the RX 480 clock charges, so we decreased the core clock right down to 1266MHz and the reminiscence right down to 2000MHz whereas leaving the voltage to Auto and decreasing the ability restrict to -25%.  Lastly we wanted to see what an overclocked RX 480 would pull general and our sadly solely will get to 1325MHz earlier than turning into an unstable mess, however the reminiscence would stand up to 2250MHz in order that was a win for it.  On the finish of it all of the 12nm Polaris 30 chip is a little more environment friendly than the inventory configuration would lead you to consider, it sadly sees a little bit of runaway when you begin cranking the speeds on up. However it’s good to see that if you happen to needed to tweak issues down you’ll be able to minimize off a bit of warmth and energy draw whereas nonetheless retaining most all this playing cards efficiency. Or if you happen to’d somewhat take heed to me go on for about 10 minutes relating to these assessments hit the video beneath.

Nitro+ RX 590 Auto Default 1560MHz 2100MHz


This didn’t begin out as one thing I assumed I’d discover terribly attention-grabbing, Polaris has been round for fairly a while at this level.  However, what I used to be not anticipating was to have as a lot enjoyable tweaking about with core settings.  Out of the field that is essentially the most highly effective Polaris has ever shined, however like a shiny star it’s consuming lots of vitality to take action.  The efficiency uplift for the reason that RX 480 got here available on the market is de facto one thing to behold seeing how far AMD has been in a position to stretch the silicon.   Tweaking the ability restrict and voltages confirmed the place the node refinement and remodeling of the core design improved, if Polaris 10 had launched with this a lot headroom in clocks and effectivity I believe the story of Polaris had gone way more in AMDs favor.  Whereas I’m nonetheless not offered on calling it a x90 class GPU because it’s not a bigger core design than the 480/580 it positively deserved greater than being referred to as ‘a 580 rebadge’ maybe RX 580+ or RX 585 would have been extra becoming and simpler to digest.  However with that gripe out of the way in which the SAPPHIRE Nitro + Radeon RX 590 pumps out sufficient efficiency to utterly dominate the sub $300 market in sheer efficiency expectations.  There are nonetheless causes to think about the GTX 1060 6GB, however they’re slimmer than ever and the RX 590 could be tweaked to be simply as environment friendly as Pascal and nonetheless match it in efficiency whereas being cooler and rocking Freesync succesful screens at a way more cheap complete package deal value than the competitors. SAPPHIRE has one once more created a stable card, even when the Elvis Blue is a bit off placing, can we get a blackout mannequin guys? Please.

What About The Recreation Bundle?

AMD is providing fairly the sport bundle proper now with the acquisition of Radeon RX 570 and up playing cards.  The RX 570 and RX 580 get you a choose of two of the video games whereas the RX 590 and RX Vega lineup get you all three.  The video games included within the Radeon RAISE THE GAME FULLY LOADED bundle are:

  • Resident Evil 2
  • Satan Might Cry 5
  • Tom Clancy’s The Division 2

All of that are shaping as much as be nice titles but it surely’ll be a while earlier than you’ll be able to really get your palms on any of them as they don’t launch for some time.  This can be a particular worth add and if you happen to’re taken with or trying to choose up considered one of these titles the the whole package deal is greater than definitely worth the consideration.  I simply don’t really feel {that a} restricted time bundle ought to change the general rating of the cardboard, if it was a everlasting addition then sure.  However for now it’s an excellent worth add for patrons.


For underneath $300 you merely cannot get extra efficiency and pair that with a excessive refresh fee 1080p Freesync show and you have got a killer mixture. Whereas the default voltage is aggressive and results in excessive energy consumption it may possibly simply be mitigated throughout the Radeon Software program. However come on SAPPHIRE, can we get it in black too?
