All About BItcoin and Litecoin mining and 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…
