I think there are a lot of miners here, so how big DAG file for ETC now? More than ETH or same?
In the end of Sept, ETH dag file will be big for rigs with 4g memory, so i wanna know what coin this rigs will be mine. Zec,Exp or Etc ?
ETC DAG file is 2.14Gb, ETH DAG file is 2.09 Gb. It depends on epoch number. Epoch number depends on avg block time. So ETC has much less avg block time (14 sec vs. 24 sec at ETH). But we have to take in consideration the fact, that GPU memory contains not only DAG, but few different stuff for work.
IMO ethash alg is better (at least for me), because lower power consumption and noise too. For example my rig has 8 x 1060 6g has 195 H/s hashrate and 725W power consumption at ethash (with overclocking and downvolting), it's very quiet and temperature no more than 56 degrees. In equihash it has 2500 Sol hashrate and 1000W power consumption, sounds like boeing and temperature can climb up to 63-70 degrees.
So I'm very glad that mining of ethash coins has the same profitability as equihash. I hope this won't be changed in future.
