Title: Mine BTC + LTC same GPU, any advantage? Post by: eroxors on April 23, 2013, 08:45:46 PM Would litecoin hash rates benefit from half of the core being used for bitcoin? In other words, bitcoin uses little/no memory so shouldn't a thread of scrypt which is allowed half of the GPU resources but the entire Memory subsystem benefit? Or would it simply be half as fast?

Any input? I guess I just need to try it out. Title: Re: Mine BTC + LTC same GPU, any advantage? Post by: eroxors on April 24, 2013, 08:24:25 PM Results on a 6970: https://docs.google.com/spreadsheet/ccc?key=0AvQpPCbSGattdEpoNmdwRm1La25EM1BhVk1feWdQYVE&usp=sharing
It seems that there is no real advantage running a thread of scrypt and a thread of SHA256 except perhaps squeaking a few KH/s or a couple MH/s on the edges (presumably by picking up unused cycles when GPU is 99%), however, my methodology is far from perfect...cgminer one window guiminer-scrypt in another... I'd be interested in someone duplicating the results. You would think that the availability of bandwidth/memory would help in script mining, but it doesn't seem to. Is there a way to dedicate a number of shaders to one thread and a number to the other? This test only utilized the intensity/gpu usage variable. Title: Re: Mine BTC + LTC same GPU, any advantage?
