Nvidia GTX 980 Performance Improvements With The Latest ccMiner 24, Nov 2014 Back in September with the release of the new Maxwell-based NVidia GPUs, the GTX 970 and GTX 980 we did some performance testing of the GeForce GTX 980 hashrate using the available at that time ccMiner and CudaMiner miners.Today, a bit over two months later we’ve decided to check how hings have progressed in terms of performance improvements of the various crypto mining algorithms with the latest optimizations available in ccMiner.We’ve used the just posted Maxwell-optimized ccMiner 1.5-git ccMiner fork from SP to get the performance results from the same GTX 980 GPU running at stock frequencies (overclocking can further increase performance).There is no surprise that there are some significant performance improvements in various crypto algorithms that have been achieved using various optimizations, but to our surprise there ware a few algorithms that did perform worse.The results we got from Groestl, HEFTY1 and JHA were a bit lower with the latest ccMiner than what we got in terms of performance back in September.

Some other algorithms also don’t seem to have very big performance improvements such as Keccak, Luffa512 or NIST5, but the more popular and still profitable to mine algorithms do come with nice improvements.You can thank for the increase in performance to all of the developers that continue to work actively and optimize the performance out of which SP and tpruvot seem to be the most active lately, djm34, tsiv as well as others who have contributed code and also Christian Buchner and Christian H. – the creators of the ccMiner in the first place.dogecoin chart priceTheir code contributions and efforts in releasing their work publicly deserve some appreciation from the miners who are using Nvidia GPUs in order to keep them motivated.earn bitcoin by surfingBelow you can find the official donation addresses where you can send some coins for a beer or more to the each of the developers: tpruvot BTC: 1AJdfCpLWPNoAMDfHF1wD5y8VgKSSTHxPo DRK: XeVrkPrWB7pDbdFLfKhF1Z3xpqhsx6wkH3 NEOS: NaEcVrdzoCWHUYXb7X8QoafoKS9UV69Yk4 XST: S9TqZucWgT6ajZLDBxQnHUtmkotCEHn9z9 SP BTC: 1CTiNJyoUmbdMRACtteRWXhGqtSETYd6Vd DRK: XdgfWywdxABwMdrGUd2xseb6CYy1UKi9jX djm34 BTC: 1NENYmxwZGHsKFmyjTc5WferTn5VTFb7Ze tsiv BTC: 1QD25HSCF8EAxUTYj2XsXZNGBi7RvQ21p8 SPR: SfSEcVQGhbXvPQ2hkTj3vxSd9PEZA12efa cbuchner LTC: LKS1WDKGED647msBQfLBHV3Ls8sveGncnm BTC: 16hJF5mceSojnTD3ZTUDqdRhDyPJzoRakM In: Tests and Reviews Tags: cbuchner, ccminer, ccminer maxwell, djm34, GTX 980, GTX 980 mining hashrate, GTX 980 mining performance, GTX 980 performance, Maxwell performance, sp, tpruvot Read More (1) Comment Nvidia GeForce GTX 970 OC vs GTX 980 Hashrate Results 24, Oct 2014 Last month we have done some initial GeForce GTX 980 crypto mining benchmarks with the announcement of the new Maxwell GPUs from Nvidia.ethereum gpu ram

Now we got our hands on a Gigabyte GeForce GTX 970 G1 Gaming video card (GV-N970G1 GAMING-4GD ) and have decided to run some tests to see how well it will fare against a standard reference design GTX 980 again from Gigabyte (GV-N980D5-4GD-B).The reference design GTX 980 we’ve used is running at stock frequencies, including the boost one and the results below are with the card not additionally overclocked, even though it can take quite an increase in the frequency.bitcoin paypal transaction volumeThe Gigabyte GeForce GTX 970 G1 Gaming card however is factory overclocked to a really high frequencies as compared to the stock ones and there is not that much left for the user to add, though some extra overclocking is also possible.bitcoin linux mining clientThe G1 Gaming card from Gigabyte also comes with the company’s Windforce cooler that proved to be a very good and silent cooling solution even when you overclock.bitcoin 24 shutdown

Also the GTX 970 model is with a factory increased max TDP level to go along with the overclock the 100% of the power limit actually represents 250W instead of 145W or 165W.This leaves a lot of headroom for more power hungry crypto mining algorithms, even though in our tests not a single algorithm was able to hit 100%.The closes we got was about 90% of the increased TDP reached with the groestl algorithm most others were keeping in the 60-70% of the 250W TDP limit.The results you can see in the table above are achieved with the ccMiner release 1.4.5-tpruvot using Compute 5.2 compiled binaries.This might not be the single best performing fork of ccminer available, however it is probably the one with most comprehensive support for various crypto algorithms (we tested with all of the supported ones) and with support for Compute 5.2.Some other forks might be able to provide slightly better hashrate on a specific algorithm, but the idea here was to do a comparison between a reference GTX 980 and a factory overclocked GTX 970 to see what you can expect in terms of performance.

The results are pretty interesting as the factory clocked G1 card is getting very close to a stock GTX 980 and with some extra user overclock it might even achieve the same results.Considering the fact that the GTX 970 is still much better priced than the GTX 980 we can easily conclude that the GTX 970 and especially GTX 970 G1 Gaming from Gigabyte is a really good choice not only for gaming, but also for mining crypto currencies.In: Mining Hardware|Tests and Reviews Tags: GeForce GTX 980, Gigabyte, Gigabyte G1 Gaming, Gigabyte GTX 970, Gigabyte GTX 980, GTX 970, GTX 970 hashrate, GTX 970 mining hashrate, GTX 970 mining performance, GTX 980 ccminer, GTX 980 crypto mining, GTX 980 for mining, GTX 980 hashrate, GTX 980 mining performance, GV-N970G1 GAMING-4GD, GV-N980D5-4GD-B, Nvidia, Nvidia GeForce GTX 980 Read More (3) Comments Crypto Mining Performance of the New Nvidia GeForce GTX 980 19, Sep 2014 Nvidia has just introduced their new high-end Maxwell-based GPUs the GTX 980 and GTX 970 and the expectations from them in terms of performance for crypto mining are pretty high.

After earlier this year we saw what the mid-range GTX 750 Ti, the first Maxwell card was capable of, we already had high hopes for the upcoming faster models.Apparently we are not going to be disappointed by the performance we are going to get, below you can see a chart with the hashrate that the new GeForce GTX 980 (GM204) provides in various crypto algorithms.These were actual tests ran using the latest versions of CudaMiner and ccMiner with support for Compute 5.0 with no special optimizations that could possibly benefit the new cards any further.In the table you can see the algorithm, the hashrate you get with the GTX 980 and the TDP usage percentage.The GeForce GTX 980 has a TDP rating of just 165 Watts, so with this maximum power consumption you can see that not all algorithms are utilizing it at 100%, meaning the actual power usage is lower.The performance you can expect to get from the GTX 980 is roughly about three times higher with about three times more power usage as compared to the GTX 750 for crypto mining.

The initial price of the GTX 980 however could be a reason for miners to go to the slightly slower GTX 970 model for crypto mining as you should be able to get two GTX 970s for a price a bit higher than for a single GTX 980 and the performance you will get from the two cards should be significantly better than from a single GTX 980.The results posted above are with a reference GTX 980 card running at stock frequency, considering that the GM204 does overclock really good, higher results can be attained when the card is overclocked.The second set of results (the OC ones) are achieved with the card overclocked to GPU at 1520 MHz, Video RAM to 8250 MHz and TDP limiter set to the maximum 125%.This is really pushing the GTX 980 to its stable maximum limits as the card really does handle serious overclock pretty well.Unfortunately we do not have access to a GTX 970 GPU for the moment, so we cannot yet test to see the difference in performance, though it should not be that high, but the 970 should be available at a much more attractive price, so it could be the more obvious choice for crypto mining rigs.
