Trying Out the New AMD Radeon R9 Fury X for Crypto Currency Mining

1, Jul 2015

amd-radeon-r9-fury-x

The latest high-end GPU from AMD, namely the Radeon R9 Fury X, that has been just recently announced has managed to provide performance high enough to be equal to the competition in the form of the Nvidia GeForce GTX 980 Ti… at least hen we are talking about using video cards based on these GPUs for gaming. We already did some benchmarks to see how fast the GeForce GTX 980 Ti is for mining, so it is time to see if the Fury X will be able to compete with these results like it does for gaming. An interesting advantage that the Fiji GPUs used in the Fury X video cards is that they come with HBM memory and both the video memory and the GPU are water cooled. In theory this means that you get lower temperatures and silent operation and the Fury X does manage to provide that. One more thing that you would normally expect from a water cooled GPU is to have a lot of potential for overclock, but unfortunately this does not hold true for the Fury X or at least not with the first card out on the market at least. We barely managed to squeeze out just about 75 MHz extra from the GPU and there is no option to overclock the video memory for the moment.

So off to do some tests with some of the popular and more profitable algorithms for mining lately, we have used the latest sgminer along with some of the optimized forks available for different algorithms such as the one optimized for Quark and Qubit. Note that there are not yet specially optimized kernels for the Fury X or settings that work best, so we were trying to use ones that we are familiar with already from the 280 and 290 series from AMD. So some of these worked really well, while others not so well and the generally available OpenCL kernels did provide quite disappointing results actually…

AMD Radeon R9 Fury X Results:
– X11 default: 6.778 MHS
– X11 Wolf0 Mod: 8.123 MHS

– X13 default: 5.614 MHS
– X13 Wolf0 Mod: 7.176 MHS

– X15 default: 4.69 MHS
– X15 Wolf0 Mod: 6.335 MHS

– Quark modified: 22.37 MHS
– Qubit modified: 21.15 MHS

– Neoscrypt default: 147 KHS

– Lyra2RE default: 287 KHS
– Lyra2RE Pallas Mod: 450 KHS

As you can see the results are a bit disappointing at this point, everything apart from the Quark and Qubit performance using the modified 280X kernels where the performance is really good and similar to that achieved on the GTX 980 Ti. Other modified/optimized kernels such as the ones for the X algorithms from Wolf0 or the Pallas mod for Lyra2Re do increase the performance a bit, but it it still disappointingly low. In fact on some algorithms you can expect to get worse results with Fury X than with a 280X for example, so we need to find better settings and maybe get optimized kernels especially for Fury X in order for that card to be viable for crypto currency mining. The only thing it is good for at the moment is for mining coins using the Quark and Qubit algorithm with the modified kernels, but then again buying a GTX 980 Ti instead could be the wiser choice for generally better mining performance for any algorithm supported… at least for the moment.

Updated Miner Control 1.6.4 Pack for Nvidia GeForce GTX 750 Ti

7, May 2015

miner-control-tool-gtx-750-ti-latest

Here comes an update to our Miner Control tool package for Nvidia GeForce GTX 750 Ti GPUs to reflect some of the recent changes. This version does add NeoScrypt support for NiceHash, WestHash and Yaamp as it was officially released in ccMiner by djm34. We have included the latest version of ccMiner 1.5.49-git Fork by SP for Nvidia Maxwell GPUs including the GTX 750 Ti, so that you can get optimum performance especially since there were quite a lot of optimizations ad fixes lately.

To be ready to use the GeForce GTX 750 Ti package you just need to update the account settings for each pool to reflect your BTC payment address. Do note that the default configuration that we have set is mining from time to time for the author of the software (Miner Control) as a donation alternative, but you can change that setting should you wish to. The package is ready to be used with GTX 750 Ti card, but you can also us it for other Nvidia GPUs or more cards (the ccMiner fork included is for Computer 5.0 and 5.2 cards only) – what you may need to reflect however in the config file is the total hashrate and power usage.

Updated Windows Binary of the ccMiner 1.5.49-git Fork by SP for Maxwell

5, May 2015

ccminer-1-5-49-git-spmod

New update in the form of a new Windows binary compiled from the latest source code of ccMiner 1.5.49-git SP-MOD fork of the Nvidia GPU miner optimized for the latest Maxwell-based video cards by SP (source). This version includes a lot of improvements and fixes such as the addition of Yescrypt and NeoScrypt support based on Djm34’s work, serious improvement for the performance of Blakecoin and more. The SP-MOD fork of ccMiner is designed for Nvidia Maxwell GPUs such as the already available GTX 750, 750 Ti as well as the newer GTX 960, GTX 970 and GTX 980. The Windows binary release we have made available here is compiled with support for Compute 5.0 and Compute 5.2 GPUs or with other words only for Maxwell-based cards with CUDA 6.5 and VS2013.
