I compared the bminer and gminer on a grinmint bminer gives a larger hash, but a rather high percentage of rejects. The gminer gives a slightly smaller hash rate, but this is offset by the lack of rejects. It should be borne in mind that the gminer loads the processor more than the bminer. The next test that I’ll run is bminer on f2pool (bminer has fewer rejects on this bullet) and grinmint on gminer. 2 identical rig. I like both the miner and the competition between them.
