The speedup is about 4x on a cpu. But since the solver becomes more similar to an Equihash solver (both dominated by bucket sorting), we can expect a similarly large gap between CPU and GPU of 10x-20x. Assuming we're happy with a mining landscape dominated by GPU cards with at least 4GB, then cuckoo30 is a preferred size, since it should take about 3GB of memory. Devices with much less memory available will have the option to use the current high latency miner, which needs less than 200MB, but for these mining will not be progress-free (they will manage only one or very few attempts per block interval, the last one of which will be wasted). regards, -John -- Mailing list: https://launchpad.net/~mimblewimble Post to : mimblewimble@lists.launchpad.net Unsubscribe : https://launchpad.net/~mimblewimble More help : https://help.launchpad.net/ListHelp
