SAPPHIRE Nitro + Radeon RX 590 Special Edition

What is RX 590 Polaris 30, RX 590 is Polaris 30 in the simplest descriptions. But what does that mean?…

What is RX 590

Polaris 30, RX 590 is Polaris 30 in the simplest descriptions. But what does that mean? Well, first with what it is not. The RX 590 is not a larger calculator calculation variant of the RX 480/580 because it still has 2304 Stream Processors. Memory configuration remains the same with 8GB of GDDR5, no G5X here but they restricted the RX 590 to only being made in 8GB variants so that no 4GB model would be downloaded. So, what’s the big essence? The manufacturing process change has led to a new model, the RX 480/580 was made on GlobalFoundries 14nm process node while the RX 590 was made on their 12nm node (which, with the design, enabled AMD to move the existing 14nm models over without rebuilding thanks to that they were the same optical size). Moving to the 1

2nm node allowed a little more height on the clock and efficiency, which we will look at later in more detail. They may have encountered TDP on the RX 590 up to 225w, but so they have allowed a significantly higher core frequency of over 1500MHz, which was the only one that the best of the best Polaris 20 chips could do to allow over 7 TFLOPS of the top calculate performance out of the box. While I would still prefer to see this card, I get a nomenclature that is more akin to an RX 580+ or ​​RX 585, because the kernel specifications outside the node, current and clock speed have remained unchanged. I think we will find that the RX 590 is a welcome addition to the Polaris family still.

SAPPHIRE Nitro + Treatment

Somewhat important to get out of the way, if SAPPHIRE Nitro + RX 590 looks familiar with design, you’re not crazy. This card retains the core design from the RX 500 series, and that’s a good thing. When we watched the RX 570 at the launch we found that the building of the card was absolutely wonderful. The RX 590 is no exception to this.

SAPPHIRE Nitro + RX 590 Special Edition goat is the solid 4 boiler design with 2x8mm and 2x6mm heat pipes that snore, even though the full envelope housing is kept cold by a pair of blue double ball bearings that make up the Dual X cooling solution. Being designed for 300w cooling this setting has no problem tamping the new, higher TDP Polaris 30 chip as you look further down.

Effect design is handled by 6-phase 50-amp card design along with Black Diamond Chokes and polymer capacitors as previously previewed 500 Series Nitro + Platform with the same 8 + 6-pin power connections that are inverted for easy installation and removal.

The included Dual Bios (wish everyone did this) gives you the default options for Nitro Boost Settings or Quiet Settings, although quiet, the silent settings may not be needed beyond the potentially reduced power consumption.

I / O of DVI-D, 2xDP 1.4 and 2xHDMI 2.0 ports along with the heat sink housing and the back plate reflects it for Nitro + RX 570 and 580, but this time with Elvis, Metallic Blue is popular. I’m going to an extremity here saying that the color can be a shutdown for many people who would rather have seen this card launch with the same, or even do the metallic black cover and backplate design as before. I get they wanted to differentiate this model, and although it looks good to myself, I do not see many people build this home in.

Test Methods

All tests were done on our Intel Z370 test drive powered by a 5GHz Core i5 8600K. We ran all tests involving the DX11 through three steps and the average results of all metrics to get to the final numbers. For DX12 and Vulkan, we used the latest version of OCAT at that time and ran the resulting file but our algorithm extracts measurement values ​​for measurement. The results are presented as Avgerage FPS, which represents where the average frame rate fell during the test, 1% Low representing the lowest 1% frame, and then represents the .1% low .1% frame. These metrics provide a better understanding of overall performance than representing the absolute minimum rate of interest, as it may potentially be a random expander, but knows that .1% can still be done by loading the load during the activity.

We compare the RX 590 to the GTX 1060 6GB FE and the Radeon RX 480 8GB today. While there will be some who are angry about the absence of the RX 580, and that’s understandable, we look at where this card performs in relation to baseline metric. The RX 480 8GB is representative of when Polaris hit the market and can show us a good then and now comparison without many additional features surrounding it, and the GTX 1060 6GB FE serves as a solid bass line for 1060 performance.

1080p Result

The Radeon RX 590 is marketed as the ultimate 1080p game card. While I’m sure there are many who would argue for the GTX 1070 or Vega 56 would love to take that place where these cards were designed and marketed for the 1440p player. At 1080p, the RX 590 definitely dominates the former Polaris GPU and goes away with a good performance over the GTX 1060 6GB FE. Even it comes close to matching it in Assassin’s Creed Odyssey, which is surprising thanks to NVIDIA’s dominance in the title across all levels. SAPPHIRE Nitro + RX 590 saw zero frequency fluctuations through all of these tests, but it kept the entire clock at 1560MHz all the time.

1440p Result

The RX 590, similar to the RX 480 8GB, is also marketed as 1440p capable. I found in early testing of the RX 480 that it could play at 1440p but with some more compromises than I really wanted to take for my personal gaming experience. So with the extra beef on the RX 590, I really hoped to see the 1440p a bit more satisfied but still got a little shy. However, it is a much more preferred experience than the cards it is up to today. I would see it comfortably run with 1440p games at average and pair with a Freesync screen that delivers the 1440p feature. SAPPHIRE Nitro + RX 590 saw zero-frequency fluctuations through all of these tests, but it maintained the entire clock with the 1560MHz clock all the time.

Synthetic, Power and Heat

Over time I have come to limit my synthetic tests as they are simply not what indicates game performance but still the server as a good identifier of how short distances are from raw power.

The Dual X cooler on SAPPHIRE Nitro + RX 590 is the best when you give everything it can take. Both the heat value and power draw numbers below were taken after 30 minutes of 3DMark Firestrike Combined Test. This gave the card enough time to settle on thermals, bell and power. I have to repeat that through these tests SAPPHIRE Nitro + RX 590 saw zero-frequency fluctuations through all of these tests, it always kept on 1560MHz clock.

Undervolting Explored

Since the launch of the RX 480, we discovered that Radeon cards benefited greatly from undervolting. In fact, they tend to take advantage of this more than overclocking in terms of overall performance. Rather than focusing on overclocking performance, we wanted to see how performance, power and thermal responses responded to fine tuning of the Polaris 30 GPU. We did it in some ways that began to take our baseline performance from earlier. Then we underestimated the P states down to when they crashed at 1050mV and then bumped them up to 1075mV for stability and lowered the power limit to -10%, as someone would lower the clock frequency sometimes. To see where the RX 590 would be overall about the matched RX 480 clock frequency, we reduced the clock to 1266MHz and reduced to 2000MHz while the voltage was set to Auto and reduced the current limit to -25%. Finally, we needed to see what an overclocked RX 480 would go in total and unfortunately we only reach 1325MHz before it becomes an unstable mess, but the memory would get up to 2250MHz so that was a profit for it. At the end of this, the 12nm Polaris 30 chip is a little more efficient than the storage configuration would lead you to think it’s a bit lost when you begin to switch the speeds up. But it’s nice to see if you want to tweak things down, you can cancel some heat and power while retaining most of the card’s performance. Or if you’d rather listen to me, continue for about 10 minutes for these tests, you met the video below.

This did not start like anything I thought I would find very interesting, Polaris has been around for quite some time. But what I did not expect was to have so much fun to do with the core settings. Outside the box, this is the most powerful Polaris ever lysite, but as a bright star it consumes a lot of energy to do it. The performance increase since the RX 480 came on the market is really something to see how far AMD has been able to stretch silicon. Managing the power limit and the tensions showed where node improvement and reworking of the core design had been improved if Polaris 10 had launched with so much main watch in watches and efficiency. I think the story of Polaris had gone a lot more in AMD’s favor. While I’m still not sold to call it an x90-class GPU because it’s not a major core design than 480/580, it definitely earned more than called “580 rebadge”, maybe the RX 580+ or ​​RX 585 would have been more appropriate and easier to melt. But with the grip of the SAPPHIRE Nitro + Radeon RX 590 method, it pumps out enough performance to completely dominate the $ 300 market in clean performance expectations. There are still reasons to consider the GTX 1060 6GB, but they are slimmer than ever, and the RX 590 can tweaked to be as effective as Pascal, and it still matches performance while shrinking Freesync-compatible screens much more reasonable total package cost than the competition. SAPPHIRE has once again created a solid card, although Elvis Blue is a little off putting, can we get a blackout model guys? Please.

What about the game package?

AMD offers the right bundle package right now with the purchase of the Radeon RX 570 and upcards. The RX 570 and RX 580 give you a wealth of two of the games while the RX 590 and RX Vega series get you all three. The Games Included in the Radeon RAISE THE GAME FULLY LOADED bundle are:

  • Resident Evil 2
  • Devil May Cry 5
  • Tom Clancy’s Division 2

Everyone is designed to be good titles but It will be time before you can actually take care of any of them, because they do not start for a while. This is a definite value add and if you are interested in or looking to download one of these titles, the total package is more than worth the price. I just do not know that a limited time bundle would change the card’s total score if it was a permanent addition then yes. But for now it is a very good value for buyers.


For under $ 300, you simply can not get more performance and pair it with a 1080p Freesync screen with high resolution and you have a kill combination. While the standard voltage is aggressive and leads to high power consumption, it can be easily relieved within the Radeon software. 9 7
