In this article we would like to review AMD Radeon RX 570 form mining using different algorithms. First we will discuss Sapphire NITRO + Radeon RX 580 Limited Edition. This is one of the best Sapphire RX 580 models. It has a higher clock frequency (factory setting) than most other RX 580 GPUs, and there are additional components, such as spare fans.
The model has improved cooling compared to Sapphire RX 480 NITRO+. And of course, the new model is more expensive. The new RX 580 – called PULSE – are similar to last year’s Sapphire RX 480. Let’s take a look at its tech specs.
SAPPHIRE Radeon RX 580 8 GB overview
RX 580 main characteristics:
- 2304 stream processors
- 14 nm. FinFET, Graphics Core Next (GCN) 4th generation
- 1450 MHz clock frequency, can be overclocked
- 8192 MB of GDDR5 memory, 256-bit memory, 2000 MHz RAM
- Display options: 1x DL-DVI-D, 2x HDMI 2.0b, 2x DisplayPort 1.4
- Reinforced Dual-X 95 mm fans with two ball bearings
- Connections: 1x 6-pin PCI-E, 1x 8-pin PCI-E
- Power Consumption: 225W
- Double UEFI BIOS
A new and larger cooler is a nice improvement, as are spare fans for the RX 580 NITRO + LE. RX 580 non Limited and RX 570 NITRO + are now equipped with the same coolers.
Another noticeable difference is the use of an additional power connector in the NITRO + RX 5 × 0 series, which have one 6-pin and one 8-pin PCI-E connectors. An additional power connector is required due to higher clock speeds, and, as a consequence, due to increased power consumption. This can be a problem for miners if they want to connect 6 such cards in one farm to one power supply. It should be noted that the PULSE series have one, not two PCI-E power connectors.
What does the GPU-Z specification say? The GPU clock generator works fine at a frequency of 1450 MHz and allows for a little overclock up to 1500 MHz. Of course, this is not much. An increase in the operating voltage up to 1.1750 V is required for overclocking, which leads to an increase in power consumption to more than 140 W (for Power Draw, according to GPU-Z).
Ethash Ethereum mining
Video memory operates at 2000 MHz, and I wanted to see Samsung GDDR5 results because this is the limited edition flagman Sapphire RX 580. But unfortunately, Sapphire went for Hynix memory. Therefore, its performance will no longer be optimal for Ethash (Ethereum) or Equihash (Zcash) where memory usage is intense.
Here is some information on benchmark tests for popular algorithms used by profitable miners. Using the latest version of Claymore Dual ETH miner, we get a speed of about 22.5 MHS from Sapphire NITRO + Radeon RX 580 Limited Edition.
It’s disappointing really considering all possible settings. Due to Hynix (2000 MHz), the timing diagrams are relaxed, apparently in order to maintain a higher operating frequency. Maybe you would be better of using a Samsung GDDR5. But Sapphire really failed us…
ZEC mining with the Claymore ZCash processor AMD GPU Miner 12.4 shows similar results. But Equihash uses memory more intensively. The average transfer rate for ZCash (ZEC) with this GPU is about 296 H / sec.
The reason for such a low data rate may be the Hynix memory, or it may be due to a new AMD driver (with RX 500 support). The official AMD driver Radeon Crimson ReLive Edition 17.4.3 (for RX 500), apparently, is not into crypto mining.
Here are a few more test results for our Sapphire NITRO + Radeon RX 580 Limited Edition card:
- DCR: 1,202 GHS
- XMR: 600 H / s
- LBC: 0.165 GHS
- PASC: 0.830 GHS
- SIB: 8.2 MHS
As for optimization, you can experiment with memory to achieve better results. In addition, lowering the GPU frequency (by default) will also reduce voltage and achieve lower power consumption. This is especially true for ETH optimization, although ZEC will require a slightly higher voltage (and clock frequency).
Some miners also report that the RX 580 LE operated normally on one 8-pin PCI-E connector. But to see for yourself, you need to optimize the frequency and voltage to avoid overloading.
So, what do we get in the end? Sapphire NITRO + Radeon RX 580 Limited Edition it is clearly designed for gamers although it can seem attractive for miners,. The clock frequency potential is more suitable for games. Miners may acknowledge a large cooler and additional fans. But two power connectors and increased power consumption are not desirable.
The RX 580 LE setup is a little disappointing, but you can see some “performance / power consumption” variations (you could get the same results with RX 580 or even the RX 570 though).
RX 580 8gb hashratein the mining ETH + DCR.
The first screen shows RX580 8GB performance with a core frequency of 1150MHz with a BIOS for the dual ETH and DCR mining. With these low frequencies, the GPU displays 30 Mh / s for ETH + 1000MH / s for DCR. Claymore 9 miner was used.
The second RX580 8Gb is used for ETH mining and achieved 24.5 MH / s.
We can conclude that the performance of new RX 580 does not exceed previous RX 480. But since the RX 480 is quite hard to find, the RX 580 will make an excellent choice, as of September 2017.

Radeon RX 580 is based on the GPU Polaris 20 and its architecture is similar to Polaris 10. However, it has been optimized. The base frequency and Boost is set at 1.257 and 1.340 MHz. Other GPUs demonstrate a higher clock frequencies exceeding 1.400 MHz.
The Radeon RX 580 is equipped with 4 or 8 GB of video memory. But we recommend 8 GB, so that performance is not limited by memory. The video memory is connected via a 256-bit interface. The clock speed is 2.000 MHz, so the bandwidth reaches 256 GB / s. It has 36 CUs, 2.304 stream processors, 144 texture units and 32 ROPs.
