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?

New GMiner v1.35 With Better Nvidia Performance and Improved AMD Support

7, Mar 2019

The newest GMiner 1.35 miner comes with improved performance for Grin29 and Swap on Nvidia cards, additional support for mining on AMD video cards for Grin29, Swap and Aeternity (adding to the already available support for BEAM), improved pool side hashrate for Swap and various bug fixes. The performance for GRIN’s Cuckaroo29 and SWAP’s Cuckaroo29s algorithm is currently probably the fastest compared to other available miners (tested on Windows 10 with GTX 1080 Ti). The additional algorithms getting AMD GPU support is nice, though not that useful as these mining rigs are not performing that good with the specific algorithms and the expected profit is not attractive at all at this point. Still it is good to have more alternatives for miners for different algorithms, so it will be good to see GMiner getting support for additional algorithms on AMD as well.

The GMiner Nvidia CUDA miner requires an Nvidia GPU with CUDA compute capability 5.0 or later as well as CUDA 9.0 driver support. Do note that GMiner is a closed source miner for Nvidia GPUs with binaries available for both Windows and Linux, also there is a 2% developer fee built-in the software.

New NBMiner 21.0 With Improved Performance and Stability for Grin29 and Grin31

6, Mar 2019

The latest NBMiner 21.0 that has just been released comes with support for Aeternity (AE) as well as improved miner stability and performance for the Grin29 and Grin31 algorithms (Cuckaroo29 and Cuckatoo31). Performance wise the new version does seem to catch up to the competition regarding Cuckaroo29 hashrates (the latest Gminer is still slightly faster) and could currently be the fastest miner for Cuckatoo31 in terms of hashrate (at least for Windows on GTX 1080 Ti) compared to BMiner and GMiner. Stability wise Cuckatoo31 however could use some more improvements as we see the miner crashing on some systems that otherwise work just fine with competing miners.

We remind you that the NBMiner is a closed source GPU miner for Nvidia CUDA that is available for both Windows and Linux operating systems and it has the following developer fee built-in: tensority + ethash – 3%, tensority (Pascal GPUs) – 2%, tensority (Turing GPUs) – 3%, ethash – 0.65%, cuckaroo29 and cuckatoo31 – 2%.
