Ethereum Mining Performance with Ethash Algorithm – RX 580 (8G) GPUs
The video memory operates at a frequency of 2000 MHz, and here I would like to see Samsung GDDR5, tk. We are talking about the top model among the RX 580 from Sapphire and the limited edition. Unfortunately, Sapphire decided to install Hynix memory. Therefore, performance will no longer be optimal for algorithms such as Ethash (Ethereum) or Equihash (Zcash), where memory usage is very intensive.
And now for the benchmarks containing some of the popular algorithms currently used by the most profitable miners. Using the latest Claymore Dual ETH miner , we get around 22.5 MHS from SapphireNITRO + Radeon RX 580 Limited Edition.
A disappointing result when you consider the use of all possible settings. Due to the use of Hynix (2000 MHz), the timing diagrams are relaxed, apparently again in order to maintain a higher operating frequency. If used Samsung GDDR5 it might be better. But Sapphire didn’t do it …
A similar and not very successful result can be seen in mining ZEC with the Claymore ZCash AMD GPU Miner 12.4 processor, but as you know, the Equihash algorithm is more memory intensive. The average data transfer rate for ZCash (ZEC) with this graphics card is about 296 H / sec.
The reason for such a low data transfer rate may be the same Hynix memory, or it may be due to a new AMD driver (with RX 500 support). And the official AMD Radeon Crimson ReLive Edition 17.4.3 driver (also for the RX 500) is apparently not very efficient for cryptocurrency mining.
