what is geth ethereum
CPU Mining with Geth. At Frontier, the first release of Ethereum, you'll just need a) a GPU and b) an Ethereum client, Geth. CPU mining will be possible but too inefficient to hold any value. At the moment, Geth only includes a CPU miner, and the team is testing a GPU miner branch, but this won't be part of Frontier. The C++ implementation of Ethereum also offers a GPU miner, both as part of Eth (its CLI), AlethZero (its GUI) and EthMiner (the standalone miner).
