In the graphics card sapphire NITRO + RADEON mining cryptocurrency …
We introduce you to the GPU’s AMD Radeon RX 5×0. The first graphics processor we will discuss is a review – Sapphire NITRO + Radeon RX 580 Limited Edition. This is one of the best models RX 580 from sapphire. She has a higher clock speed (default setting) than most other graphics RX processors 580, and there are other components, such as spare fans. The model has improved cooling compared to the Sapphire RX 480 NITRO+. And, of course, new models come at a higher price. The new map RX 580, which in many ways resembles last year’s Sapphire RX 480, will now be called Pulse. Let’s take a look at the specs.

New larger cooler – a nice improvement as well as a spare fan for the RX 580 NITRO + LE. Tsapphire NITRO+ Radeon RX 580 8 GB limited edition Another notable difference is the use of additional power connectors in the NITRO + RX series, where x5 0 a 6-pin and an 8-pin PCI-E connector. Additional power connectors are required due to higher clock frequencies and as a result of increased power consumption. Miners may be a problem if they want these cards 6 to be connected to the same power source. It should be remembered that the series PULSE is one, not a two-slot PCI-E power supply
What is said in the GPU-Z specification? The clock generator GPU works well at 1450 MHz and allows bits to be spread to 1500 MHz. Of course, this is not much. In order to increase the operating voltage to 1.1750 B, this also results in an increased energy consumption of more than 140 watts required for the clock frequency (power drawing, according to GPU-Z). The memory clock frequency is 2000 MHz, and here I want to look at the Samsung GDDR5 because we are talking about the top models of the sapphire and the limited edition RX 580. But unfortunately, in the sapphire we decided to install the memory Hynix. So performance will not be optimal, the algorithm of Ethash (revenge) or Equihash (Zcash), where the use of memory is very dense.
And now the benchmarks, including some popular algorithms, are currently used by the most profitable miners. Using the latest version 9.2 Claymore double ETH miners, we got a limited edition of 25% MHS from the Radeon RX 580 from Sapphire NITRO+. For disappointing results, consider using all possible settings. Since the use of Lux (2000 MHz) is relaxed, the timing diagram is obviously again in order to maintain a higher operating frequency. If you use Samsung GDDR5, it might be better. But Sapphire did not do this?
This is not the most successful result. I can see the processor Claymore ZCash AMD GPU miner 12.4.No in Meiningen ZEC, because we know that the Equihash algorithm takes up a lot of memory. The average data rate (ZEC) for ZCash and this video card is approximately 296 H / sec. The reason why such a low data rate can be all the same memory force, or it may be due to the new AMD driver (RX support 500). And AMD’s Radeon Crimson Renewed version 17.4.3 official version of the driver (also RX 500) does not seem to be very effective for mining kriptovalyutnogo.
Below are some of the results of the test for our Card Sapphire NITRO+ Radeon RX 580 Limited Edition:
- DCR: 1202 GHS;
- XMR: 600 H / SES.
- LBC: 0.165 GHS;
- PASC: 0830 GHS;
- SIB: 8.2 MHS.
As for optimization, you can experiment with memory rulers and achieve the best results. In addition, lowering the frequency with the upper value (default) will also allow for lower voltages and lower power consumption. This is especially true for ETH optimization, despite taking a slightly higher voltage (and frequency) of the ZEC. Some miners also reported that the board RX 580 LE can run independent verification on a single 8-pin PCI-E.No, and you need to optimize the frequency and voltage to avoid overfeeding.
What conclusion? The limited edition of the Sapphire NITRO+ Radeon RX 580, although the miners are attractive, it is clearly designed for gamers. The possibility of increasing the clock frequency is more suitable for the game. The miners are also like a big cold fan in a pack. But two power connectors, as well as high power consumption – can be pleased. The RX 580 LE configuration retains a bit of disappointment, but some changes in “performance/power” can be seen (the same result can be obtained by setting RX 580 and RX 570, even). Ie in some settings – this is a miner, but the price is unlikely to look very kind.
