ETH mining on the GTX 1070 ti is a waste - they do a LOT better on equihash algorithm coins among other choices.
The reason the TDP isn't having much effect is that the ethhash algorithm is VERY memory-limited, so dropping the core clock on MOST cards doesn't affect the hashrate for a long time as the memory can't FEED the core enough data to keep up with it.
Even the R9 290/390 with their 512 bit memory bus can run the core at noticeably "lower" settings than on most coins and still hit max hashrate on ethhash.
Thanks for the explanation, I was just curious what kind of hash/s my rig would get, i don't have any plans mining ETH for now
