Can someone tell whether the 3GB version of the GTX1060 performs similar to the 6GB version in XMR? Currently I get 530 H/s @ 40W out of my overclocked GTX 1060 6GB, is the same possible with the smaller brother? Performance seems only to be dependant on the memory clock, not on the cores, so the fewer cores should not matter?
Maybe 6GB has better timing? But generally for XMR doen't matter if you have 3GB or 6GB, same for AMD 4 or 8GB. Core clocks matter.
The "3GB" 1060 does not use the same GPU as the "6GB" 1060 - has a few less cores (768 vs 896 I think, might be 896 vs 1024), so it probably WILL perform a little lower on Monero.
IMO Nvidia should be facing a fraud lawsuit over their naming of the "3GB 1060".
AWS is very "negative' on cryptocoin mining on their servers (Azure and Google Cloud are about as negative) - they WILL shut your account down with no credit issued if they catch you at it, and they have the legal right to do so as a "contract violation".
As far as Monero hashrate jump the last month - I'd bet on it being folks that moved over from OTHER cryptocoins due to the price spike that briefly put Monero ahead of most other coins for mining with MOST GPUs - no need for no botnets, just the long-standing tendancy of many cryptocoin miners to "chase the most profitable coin of the day or hour".
I am pretty sure at least a couple of the "multi-aggro pools" like Suprnova support Cryptonight mining as well as Nicehash, which would also account for some of the extra hashrate.
