assuming you increased some algo to 10-20%, the same will happen for the 1080, so add 20% more on top of that hashrate...
This is not the case. I have a few that has tested the "public" private bins, and they are sometimes slower than the opensource.
My buyable private Spreadcoin #9 is up 0.6MHASH on the 1070 and 1MHASH on the 1080 compared to the opensource.
1070: 6000 -> 6600
1080: 7500 -> 8500
you still need to tweak it for the pascal, you can squeeze some more hash from it
AND Neoscrypt (half the performance of 970). Those are basically all the algos that are worth mining right now besides Lyra2. CMB did some testing, couple people posted it here. Considering there is only one algo for 1xxx series to mine, expect that one to start dipping down to the other shit algos like blake.
So you're essentially mining for one coin with the 1xxx series.
Not one to hate, but your math in this case is seriously lacking.
In other news, Nicehash really needs a auto-upload mode for their benchmark mode in their miner. Right now, the only place to go to look at GPUs is like here:
http://62.212.74.86/~mining/list/index.php?brand=amdThat's a giant list of shit, mixed clocks, versions of sgminer (for instance), multiple GPUs in some cases(!?!?), and you can barely sort it let alone separate it. A bit of automation in this case would be super helpful. I was trying to find some data on the latest versions of sgminer, but it's a shit show.
you will never know what the best algo will be for the future, all i know is that i will never mine for one algo, EVER, this si like having an asic, which i hate to death
my math is right, and it is based on my consumption, but you are actually losing money by missing the 50% more hash that a 1070 can give to you right now over the 970 or over any other amd
also what you're talking about when saying "half the performance"? currently a 1070 can mine at 1MH on neoscrypt which is 50% more than a 970, and this without any optimization for pascal
