VulkanXMRMiner 0.3 Vulkan and SPIR-V Miner With CryptoNightR Support (CNv4)

11 Mar
2019

VulkanXMRMiner is a new GPU miner that is based on Vulkan and SPIR-V technology and not OpenCL, like most other AMD miners out there, so it should work on any Vulkan 1.0 compatible device: AMD, Intel or Nvidia. VulkanXMRMiner is available for both Linux and Windows and it requires Vulkan support installed with a recent video drivers in order to function. The miner supports Monero (XMR) with its newest variant CNv4 (CryptoNightR) as well as Wownero (CryptoNightV8), Aeon (CryptoNight Light) and TurtleCoin (CryptoNight Turtle) as well as other crypto coins that are based on any of these algorithms. The miner is open source, however the already compiled binaries do come with a 1% development fee for the further development of the software. Feel free to share your settings and performance results should you try this Vulkan-based Cryptonight miner on your mining rigs…

The Latest XMR-Stak 2.10.0 is Ready for CryptoNight R for CPU, AMD and Nvidia

8 Mar
2019

With Monero (XMR) forking in a day to te new CNv4 (CryptoNight R) algorithm there are more GPU miners getting ready and supporting the new algorithm and the latest XMR-Stak is no exception. It might not be the first to support CryptoNight R as SRBMiner has been available for a while for AMD with CNv4 support. XMR-Stak 2.10.0 however does offer support not only for AMD GPUs, but also for Nvidia and even CPU miners, so it is your universal CryptoNight R miner. Performance wise in our initial tests XMR-Stak is just slightly faster in terms of hashrate compared to the latest SRBMiner 1.8.0, but the advantage is neglectable and the difference with the default developer fee eats away the additional hashrate you get.

Of course it also supports number of other CryptoNight variants including the new cryptonight_v8_reversewaltz used by Graft with their recent fork and pretty much any other more popular CN variant out there as well. Do note however that the official binary release comes with a 2% development fee, you can compile the miner yourself from source (it is open source) with different or even no developer fee however should you decide to.

What About the Sapphire RX 570 16GB GPUs With ePIC Boost Miner for GRIN

7 Mar
2019

Back in January this year Sapphire, a popular name among AMD GPU miners, has announced their RX 570 GPUs with 16GB of video memory intended for use for GRIN crypto mining and more specifically the Cuckatoo31 algorithm that requires more video memory and can take advantage of the extra VRAM on these GPUs. This might have sounded interesting for some miners at least initially after the launch of the GRIN network and the hype and high initial price of the Grin coins, but things look different now. Miner developers have been able to optimize and enhance performance on 8GB+ Nvidia GPUs for the Cuckatoo 31 algorithm and the $399 USD mining GPU from Sapphire with just 6 months warranty already seems like a total joke when you compare performance…

The latest version of the miner specifically optimized for Grin mining on the Sapphire RX 570 16GB mining video cards ePIC Boost Miner supporting both Cuckaroo29 and Cuckatoo31 is apparently capable of delivering up to 2.6 G/s for Cuckaroo29 at 163W and up to 0.47 G/s for Cuckatoo31 at 195W if you have a top specs computer used for mining and not what a traditional GPU mining rig looks like. These results are for a mining rig with i5/i7/i9/Ryzen Multithreading CPU, PCIe 3.0 with Atomics and AMD ROCm Linux driver. If you use a low-end Celeron/Pentium CPU, like most GPU mining rigs do, PCIe 2.0 bus for the GPUs and the AMD GPU Pro driver you will be down to 1.5 G/s for Grin29 and 0.35 G/s for Grin31 according to the latest official performance results.

Now, how does an Nvidia GTX 1080 Ti with 11GB of video memory compare with the currently fastest Cuckatoo31 miner NBMiner 21.0 under Windows 10 on a normal low-end mining rig with a Celeron CPU. You can easily get about 1.3-1.35 G/s with about 200W of power usage (lowered down TDP of the GPU, up to about 1.45 G/s with stock TDP) to get similar power usage as with the AMD. You get almost three times the performance with the Nvidia at the same power usage with two to three times the price of the AMD mining GPU from Sapphire and without a number of specific requirements that are not easy for a lot of miners.

The answer to the question are the Sapphire RX 570 16GB mining GPUs worth it at the moment is a simple NO! But what about the performance for the upcoming Grin Cuckatoo 32 protocol upgrade planned for 2020… well, who knows, but what will you be doing by then?
