SAPPHIRE Nitro + Radeon RX 590 Special Edition

What is RX 590?

In the simplest explanations of Polaris 30, RX 590 is Polaris 30 & # 39; But what does that mean? Well, not with what first. Because the RX 590 still carries the 2304 Flow Processor, the RX 480/580 is not a larger Calculator Unit number variant. The memory configuration remains the same as the 8 GB GDDR5, where there is no G5X, but the RX 590 has been restricted to 8GB only, so the 4GB model should not be available. So, what's a big fuss? The production process change created a new model, RX 480/580, GlobalFoundries 14nm made on the processing nodes, and RX 590 was made from the 12nm node (with the design, AMD allowed the redesign of existing 14nm designs without redesigning the same optical size). Moving to a 12nm node allowed a little more space per hour and more power efficiency for more details. The RX 590's TDP may have hit up to 225w, but in doing so, the best Polaris 20 chip is the best 7 core to allow TFLOPS to have a higher core than the 1500MHz. frequency allowed. The peak performance is out of the box. If I choose to see this card, however, if I get a nomenclature similar to the RX 580+ or ​​RX 585, the core features outside the node are still a nice addition to the Polaris family of the RX 590 because the power and clock speeds remain unchanged.

SAPPHIRE Nitro + Purification

If the SAPPHIRE Nitro + RX 590 looks familiar in the design, then you won't be mad. This card protects the core design from the RX 500 series, and that's a good thing. When we launched the RX 570, we found the card's structure absolutely great. The RX 590 is no exception to this.

The SAPPHIRE Nitro + RX 590 Special Edition achieves 4 heat pipe designs, filled with 2 x 8mm and 2x6mm heatpipe, while the full-size heasink is cooled by a pair of double-ball double ball bearings forming the Double X cooling solution. Designed for 300w cooling, it's not hard to match the new high TDP Polaris 30 chip as you'll see at higher levels.

Power design along with 6-phase 50amp circuit board design, Black Diamond Chokes and polymer capacitors preview are reversed for ease of installation and disassembly with the same 8 + 6pin power connections as the 500 series Nitro + card design.

The supplied Dual Bios (ask everyone to do this) gives you the default Nitro Upgrade settings or Silent Settings options, but make sure that the silent settings are perhaps required outside of less power consumption.

A DVI-D is the same as the Nitro + RX 570 and 580 with the I / O water, cooler jacket and backplate mirror of the 2xDP 1.4 and 2xHDMI 2.0 ports, but this time Elvis loves Metallic Blue . I'm going out of a limb here, and I'm telling you that it's possible for a lot of people who prefer to see this card launch more or less like a metal, black blanket and back plate design as before. . I wanted to differentiate this model, and although it looks good, I do not see many structures that seem right at home.

Test Methodology

All tests were performed on our Intel Z370 test bench with 5 GHz Core i5 8600K. We conducted all the tests in DX11 in 3 steps, and we took the results of all numbers on average to come to the final numbers. For DX12 and Vulkan, we used the latest version of OCAT at this time and we ran the resulting file in spite of our algorithm for extracting measurements for measurement. The results are presented in the form of Avgerage FPS, which represents the place where the mean frame rate falls during the test, representing 1% Low representing the lowest 1% of the frames and then .1% low representing 1.1% of the frames. These metrics provide a better understanding of overall performance than represent the absolute minimum frame rate, since this could potentially be a random outlier, but know that the -1% value can still be affected by the asset load during operation.

Today we compare the RX 590 with the GTX 1060 6GB FE and the Radeon RX 480 8GB. There will be some sour people about the absence of RX 580, and although this is understandable, we're examining where that card performs in relation to its initial metrics. The RX 480 8GB represents the time when Polaris entered the market, and without a lot of extras surrounding us, it can now perform well and the GTX 1060 6GB FE serves as a solid base measurement for its 1060 performance.

1080p Results

The Radeon RX 590 is marketed as the ultimate 1080p game card. I'm sure the GTX 1070 or Vega 56 has a lot to do with this card, but these cards have been designed and marketed to 1440p players. In 1080p, the RX 590 surely dominates the previous Polaris GPU and comes with a robust performance pioneer on the GTX 1060 6GB FE, which is surprising even on all floors due to the dominance of NVIDIA in this title, the Assassin's Creed Odyssey. 39; The SAPPHIRE Nitro + RX 590 saw zero core frequency fluctuations throughout all these tests, always maintaining the full 1560MHz core clock.

1440p Results

Like the RX 480 8GB, the RX 590 is also marketed with 1440p capability. In the first tests of the RX 480, I learned that I could play in 1440p, but I made a little more concessions than I wanted to get for my personal gaming experience. I was hoping to satisfy the 1440p game with the added beefcake of the RX 590, but it was still a little shy. However, it is a much more preferred experience than the cards it faces today. I was able to see that the 1440p is augmented comfortably in the Medium settings and matched a Freesync screen with a 1440p capacity. The SAPPHIRE Nitro + RX 590 saw zero core frequency fluctuations throughout all these tests, always maintaining the full 1560MHz core clock.

Synthetic, Power and Thermals

Over time, I've come to limit my synthetic tests so that it isn't just an indicator of gaming performance, but I don't see it as a good descriptor of how cards are moving away from their raw power figures.

The Dual X cooler on the SAPPHIRE Nitro + RX 590 is the best when you have everything you can buy. The following thermal and power draw numbers were taken after the 30 minute cycle of the 3DMark Firestrike Combined Test. This gave the card enough time to synchronize to deadlines, core clock, and power traction. I repeat with these tests that SAPPHIRE Nitro + RX 590 & # 39; sees zero core frequency fluctuations during all these tests, always maintaining a full 1560MHz core clock.

Unexplored Investigation

Since the launch of the RX 480, we have seen that the Radeon cards benefit from low voltage. In fact, in terms of overall performance, they tended to overclock more than this. So instead of focusing on overclocking performance, we wanted to see how performance, power, and thermals react when fine-tuning the Polaris 30 GPU. We've done this in a few ways, starting with our earning performance earlier. We then lowered the P states down to 1050mV and stabilized to 1075mV and reduced the power limit to -10%. In order to see where the RX 590 will generally match RX 480 clock speeds, we've reduced the core clock to 1266MHz and memory to 2000MHz, leaving the voltage to Automatic and lowering the power limit to -25%. . Finally, we had to see what an overclocked RX 480 would capture and unfortunately became a 1325MHz before becoming an unstable mess, but the memory would reach 2250 MHz, so it was a gain. At the end, all 12nm Polaris 30 chips are a bit more efficient than the stock configuration will cause you to believe, unfortunately they see a little leak when you start to crank the speeds. But if you want to fix some things, it's nice to see that you can do some heat and power shooting while maintaining the performance of all these cards. Or, if you prefer to listen to me, continue for about 10 minutes with these tests.

This didn't start as something I thought I would find very interesting, Polaris has been around for quite some time at this point. But what I didn't expect was a lot of fun with the core settings. Outside the box, this is not the most powerful Polaris ever glowed, but like a bright star, it wastes a lot of energy to do it. RX 480's rising performance in the market is really something to see how far the AMD is able to stretch the silicon. Determining the power limit and voltages showed that the core design was improved and reprocessed, and if Polaris 10 was released with so many titles and hours and efficiency, I think Polaris' story is more in favor of AMD. Although I still don't call it an x90 class GPU, it's definitely not & # 39; 580 rebadge, because it doesn't have a larger kernel design than the 480/580 & # 39; maybe RX 580+ or ​​RX 585 would be more convenient and easier to digest. The SAPPHIRE Nitro + Radeon RX 590, however, outperforms this performance, providing enough performance to fully dominate the $ 300 market in performance expectations. The GTX 1060 still has some reasons to think about the 6GB, but it's thinner than ever, and the RX 590 can be adjusted to be as efficient as Pascal, and yet it's performance when it's equipped with more cool and lively Freesync-enabled monitors. The total cost of the package is reasonable. SAPPHIRE has once again created a rigid card, can we get a man with a blackout pattern, even if it is a bit harder? Please.

What About Game Pack?

AMD is currently offering a Radeon RX 570 and a game package with the purchase of cards. RX 570 and RX 580 take one of the two games, while the RX 590 and the RX Vega series bring all three. Games including Radeon RAISE THE GAME FULLY LOADED:

  • Resident Evil 2
  • The Devil Can Cry 5
  • Tom Clancy’s Part 2

All this is shaped into great titles, but since it hasn't been published for a while, it will take a while since you will never get it. This is a particular added value and should be above the total package value if you want to take one of these titles or take care of them. I just don't think a limited time package should change the overall score of the card, if yes it is a permanent add-on. But for now, a very good value for buyers.


Under $ 300, you won't get more performance and you can't match the high refresh rate 1080p Freesync screen and you have a killer combination. The default voltage can be mitigated easily in Radeon Software, while causing aggressive and high power consumption. But come to SAPPHIRE, can we have a black one?
