Radeon RX 580

In this post, we are going to provide a review of AMD Radeon RX 570 video card and its performance in mining with various algorithms. The GPU in question is Sapphire NITRO + Radeon RX 580 Limited Edition. This is one of the best RX 580 from Sapphire models. It has a higher default clock frequency than most other RX 580 GPUs. Also, it provides additional components such as spare fans.

The model has an enhanced cooling system compared to Sapphire RX 480 NITRO +. Obviously, the new model comes at a higher price. New RX 580 cards follow the lead of the last year’s Sapphire RX 480 and are called PULSE. Let’s take a closer look at the features.

SAPPHIRE Radeon RX 580 8 GB Review

Main RX 580 product specs:

  1. 2304 stream processors;
  2. 14 nm FinFET, fourth-gen Graphics Core Next (GCN);
  3. 1450 MHz of a clock frequency (GPU boosting possible);
  4. 8192 MB of GDDR5 memory, 256-bit memory bus, 2000 MHz RAM clock speed;
  5. Display ports: 1x DL-DVI-D, 2x HDMI 2.0b, 2x DisplayPort 1.4;
  6. Upgraded Dual-X 95 mm fans with two ball bearings
  7. Power Connectors: 1×6-pin PCI-E, 1×8-pin PCI-E;
  8. Power consumption: 225W;
  9. Dual UEFI BIOS.

A new and larger cooler is a welcome improvement as are the spare fans for RX 580 NITRO + LE. RX 580 non Limited and RX 570 NITRO + are now equipped with the new coolers as well.

Another noticeable difference is made by an additional power connector for the NITRO + RX 5 × 0 series which have a 6-pin and an 8-pin PCI-E connectors. Additional power connector is required due to the higher clock frequency and, therefore, increased power consumption. This can be a problem for miners, should they want to connect six cards to a single power supply. It should be noted that PULSE products have one PCI-E power connector instead of one.

What does the GPU-Z specification have to say? The GPU clock generator operates great at 1450 MHz frequency and allows to further boost the card to 1500 MHz. Sure, it’s not that much. To increase the clock frequency, one would need 1.1750V which results in the subsequent increase of the power consumption to more than 140W (according to GPU-Z, this applies to Power Draw).

Let’s move on to the benchmark tests run on some of the popular algorithms currently used by the top revenue-generating miners. The latest version of Claymore Dual ETH miner and SapphireNITRO + Radeon RX 580 Limited Edition delivers the speed of about 22.5 MHS.

This is not a very promising result given the potential application of all available settings. Hynix (2000 MHz) doesn’t work out great for the timing diagrams which is the downside of trying to maintain a higher operating frequency. Using Samsung GDDR5 could have possibly rectified the issue but Sapphire did not deploy this option.

We can observe similar results for ZEC mining with Claymore ZCash processor AMD GPU Miner 12.4. However, as you may already know, Equihash algorithm requires a more intensive work on the part of memory. The average data transfer rate for ZCash (ZEC) with this video card is about 296 H/sec.

One of the possible reasons for such a low data transfer rate is Hynix memory. It can also happen because of a new AMD driver (with RX 500 support). Apparently, the official driver, AMD Radeon Crimson ReLive Edition 17.4.3 ( for RX 500), is not that effective for mining, either.

Here are a few more test results for Sapphire NITRO + Radeon RX 580 Limited Edition card:

  1. DCR: 1,202 GHS;
  2. XMR: 600 H/sес;
  3. LBC: 0,165 GHS;
  4. PASC: 0,830 GHS;
  5. SIB: 8.2 MHS.

As for the optimization, you can play around with memory bars to achieve better results. Additionally, lowering the GPU frequency from its maximum default value will reduce the power consumption. This is particularly true for ETH optimization as ZEC will require a slightly higher power consumption (and clock frequency).

Some miners report that RX 580 LE board can operate fine on a single 8-pin PCI-E connector. To see if this stands true, you would need to optimize the clock frequency and voltage to avoid power overload.

The bottom line? While Sapphire NITRO + Radeon RX 580 Limited Edition is quite interesting from a mining standpoint, it is clearly designed for gamers. An opportunity to increase the clock frequency would be more useful for gamers. Miners will appreciate a large cooler and additional fans. However, two power connectors and high power consumption leave us wanting more.

Flexibility of RX 580 LE settings is not outstanding, either. Still, you would be able to play around with its productivity and power consumption. Most likely, you would achieve the same results as with RX 580 or RX 570.

RX 580 8GB hashrate for mining ETH + DCR

The first screenshot gives a glimpse of RX580 8GB performance with a core frequency set to 1150MHz and BIOS mode optimized for the dual mining of Ethereum and Decred. Low core frequencies produce 30 Mh/s for Ethereum + 1000MH/s for Decred. Claymore’s version 9 miner was used.

The second RX580 8Gb video card mined ETH at the stock settings and produced 24.5 MH/s.

Acquired data allows us to conclude that RX 580 performance is not really much better than what the previous generation, RX 480, produced. However, since RX 480 is no longer available for purchase, RX 580 is going to be an excellent choice. In fact, it’s the best that AMD Radeon can offer as of September 2017.

Radeon RX 580 is based on the GPU Polaris 20. In terms of its architecture, Polaris 20 is not that different from Polaris 10. Still, the tech process was optimized, hence its new name. Base and boost clock are set at 1.257 MHz and 1.340 MHz, respectively. Other video cards can offer even higher clock rates. In fact, they can exceed 1.400 MHz.

Radeon RX 580 is equipped with 4 or 8 GB video memory. We recommend using the 8 GB model so that the memory volume would not hinder productivity. The video memory is connected via a 256-bit interface. The clock frequency is 2.000 MHz and the bandwidth is 256 GB/s. It is worth noting that there are 36 computational units, 2.304 stream processors, 144 texturing units and 32 ROPs.
