It Is All About BTC, LTC, ETH, DOGE, KAS mining as well as other alternative crypto currencies
Nvidia has just announced a new GPU architecture called Maxwell and their first GPU to use it – GeForce GTX 750 Ti. We’ve had a card for testing and decided to give it a try and see how it will perform for Scrypt mining as normally Nvidia GPUs are not providing as much hashrate as AMD graphics cards for crypto mining. The next Maxwell architecture from Nvidia however is interesting, because it is focused on optimization for better performance per watt – something that crypto coin miners are also interested a lot in. The new GeForce GTX 750 Ti GPUs have a power consumption of just about 60W and the price range for these cards is $150 USD. When you add the fact that a GeForce GTX 750 Ti based on the Maxwell architecture without overclock makes about 265 KH/s using CUDAminer these become an interesting solution for crypto miners.
CUDAminer startup parameters for 265 KH/s:
cudaminer.exe -o stratum+tcp://eu.multipool.us:7777 -u yourworker.cuda -p password -i 0 -l T5x24 -C 1
Furthermore after overclocking the GeForce GTX 750 Ti you can get close up to 300 KH/s hashrate out of the card without problems. There is a chance if the card allows higher overclocking frequencies and higher voltage operation as well as if it has external power and you can increase the power limiter to over 100% to get even higher performance out of it. Furthermore have in mind that CUDAminer is hot yet optimized to support the new Maxwell architecture and the hashrate we are getting out of it is with the kernel for the older Kepler architecture that is used for GTX 780 cards. So there is a chance for even higher performance with a specially optimized CUDAminer for the new Maxwell architecture…
While GPU mining still does work better on AMD-based graphics processors using OpenCL, the latest versions of the CUDAminer software intended for use on Nvidia-based graphics cards has gone through a good performance optimization and it makes mining with CUDA a good option if you have some spare and unused Nvidia GPUs. The fact tha there are still shortages of the Radeon R9 280X graphics cards on the market – the all-round best performer for Scrypt GPU mining makes the alternative to mine coins with Nvidia GPU a decent alternative. Of course the price/performance ratio of an Nvidia GPU versus and AMD GPU for mining is still in favor of AMD graphics. You can expect to get about 550-560 KH/s from a stock (non overclocked) Nvidia GeForce GTX 780 Ti graphics card, while the same performance is easily achievable with a much cheaper stock AMD Radeon R9 280X card. If you however have a watercooled 780 Ti and overclock it well, you might be able to reach hashrate close to about 900 kHash/s according to the author of the software. Regardless, if you already have a CUDA-capable graphics processor why not put it to some mining work to get some extra crypto coins, it also makes for a good option to try out new pools or alternative cryptos…
One of the best things about the CUDAminer software is that it automatically detects the best settings for your graphics card, so that after yo run it the software can squeeze out the maximum mining performance automatically for you. This takes the guesswork and a lot of time spent for testing different settings, though you can still do that if you wish to fine tune things. One of the still missing important features from this miner is the failover pool switching to backup pools in case of a problem with the current mining pool. CUDAminer already has support for scrypt mining with N=1024 (LiteCoin and many, many other scrypt clones like DOGE for example), scrypt-jane mining (Yacoin and several clones), scrypt mining with larger N (VertCoin) and the recently released MaxCoin mining (SHA-3 i.e. Keccak256). So you will be up to speed even with the latest alternative crypto currencies such as VertCoin and MaxCoin that have generated quite some buzz in the last few days. Below you can download the latest binary for windows of CudaMiner or you can compile it yourself from the (source).
Update: CudaMiner is now an old and non supported anymore miner for Nvidia GPUs, you should switch to the more recent and supported ccMiner instead in order to get better support, including for newer mining algorithms and coins, as well as faster hashrates for your Nvidia-based GPU mining rigs!
