It quite good algo less energy consumption. Less noise try mining hirocoin
the algo = less energy?? you are still posting this after reading the entire thread?
yes
compare SHA-256 mining with GPU to scrypt
SHA-256 was optimized to the bone with Bitcoin, it was over 99% efficient compared to a "perfect" miner that didn't waste any ops anywhere because it only had a few ops here and there that were necessary but not part of the algorithm
yet it still takes less energy than mining scrypt, when scrypt possibly isn't even as optimized (there aren't several competing scrypt kernels afaik, but for Bitcoin there was fatk, poclbm, diablo, etc.)
Ok so that sounds more like the replies we are after. Let me just understand this.
sha256 miners although almost 100% efficient running on gpu - draw less electricity and creates less heat than scrypt... can i ask by exactly how much less electricity? i've never mined sha256...are we talking 50%
sha256 mining you are sure was optimised to almost 100%? what level of optimisation do you consider x11 miners to have at this point?
Can this therefore be a direct indication and something we can even apply to x11 ?
Also is there any reason at all why x11 could or should me more efficient than QRK? in terms of heat and electricity used even when the cards calculations resources are maxed and fully optimised?
So far the answer i am getting on that is NO. However if you really think it is possible that is something we need to investigate and consider now.
the very first SHA-256 miner was only maybe 5% less efficient than the best one (poclbm was giving me good hash rates before a lot of these newer kernels optimized it by a few more percent)
people just found 1% improvements here and there a few times and after a while there were no optimizations left
some optimizations reduced the total instruction count by one out of 1300 (less than 0.1% improvement)
SHA-256 takes like 20% less energy to mine off the top of my head because it doesn't use the GPU ram as much
so I'm sure there are algorithms that take even less GPU power because they rape one part of the chip (bottleneck) and don't touch the rest of it much
