Title: 7950 or 7970 for casual mining? Post by: sandor_clegane08 on April 13, 2013, 06:51:58 PM I'm trying to decide which of these to get. Does anyone know which gives you the most bang for buck when mining? Also what sort of MH/s do you get when using these cards? Just curious how much of an improvement i'll see compared to a GTX 470 (as we know, nvidias are terrible for mining :))

7970 is you want to game since it has the most umph. 7950 if want the most bang/buck for mining. Title: Re: 7950 or 7970 for casual mining? Post by: zif33rs on April 13, 2013, 06:57:00 PM https://en.bitcoin.it/wiki/Mining_hardware_comparison (https://en.bitcoin.it/wiki/Mining_hardware_comparison)
Lots of reading to do around here. 8) Took me a couple weeks to get up to speed. Climb aboard! Title: Re: 7950 or 7970 for casual mining? Post by: nawazish1 on April 13, 2013, 07:45:09 PM Hello guys I also have a question. Why Bitcoin Hash rates are written as 1000MH/s and Litecoins as 1000KH/s.
these number are written for the same card i.e if we take example of 6990 the has rates for BTC and LTC are written as. BTC 900MH/s LTC 900KH/s What is the difference between them? I doubt that they are not written correctly. Both should be KH/s Title: Re: 7950 or 7970 for casual mining? Post by: Marrs on April 13, 2013, 08:31:50 PM Hello guys I also have a question.

Both should be KH/s The litecoin hashing algorithm takes 1000 times longer per iteration, when optimized. On equal hardware that can run both well, ltc should be btc / 1000.

Both should be KH/s scrypt (used by LTC) is more difficult than sha-256 (used by BTC), thus the lower hashrate. |
