Mining hardware comparison. See also: Non-specialized hardware comparison Below are statistics about the Bitcoin Mining performance of ASIC hardware and only includes specialized equipment that has been shipped. GPUs, CPUs and other hardware not specifically designed for Bitcoin mining can be found in the Non-specialized_hardware_comparison. Notes: Mhash/s = millions hashes per second (double sha256 raw speed performance; may not be very energy efficient with some models) Mhash/J = millions hashes per joule (energy efficiency; 1 joule of energy is 1 watt during 1 second: 1 J = 1 W*s) W = watt (maximum power consumption, i.e. energy per unit of time: 1 W = 1 J/s) Be sure to research any of these vendors and machines intensely before spending any money. ↑ Fpgaminer (May 19, 2011).
Python OpenCL bitcoin miner. Latest miner poclbm_py2exe_20120920 mirror Sources for poclbm are at Created by Kiv, see Guides Windows - Ubuntu - Mac - Known best settings(please PM better/best settings for your platform) AMD 5xxx and upuse '-v -w 128' Frequently asked questions Q: Does my video card / driver supports OpenCL?
AMD - 4xxx and up. Q: I am seeing 'pyopencl.LogicError: clGetPlatformIDs failed', what is this? You don't have proper OpenCL support. Q: When I try to run it with the following parameters: '--host= miner errors out with 'nonnumeric port' Remove ' it's intended for browsers (becames '--host=mining.bitcoin.cz'). Q: Why it uses 100% CPU? You probably selected the CPU as OpenCL device.
Q: What does 'invalid or stale' means? The block last submitted was either invalid or stale. Q: How a block becomes stale? You submited solution for a block which was just solved by someone else. Q: Why a block is invalid? Don't overclock too much. It's good if you see more 'accepted's than 'invalid's. It's console application. Mining Guide - We Use Coins.

Before you read further, please understand that most bitcoin users don't mine! If you want to get bitcoins based on a fixed amount of mining power, but you don't want to run the actual hardware yourself, you can purchase a mining contract. Another tool many people like to buy is a Bitcoin debit card which enables people to load a debit card with funds via bitcoins. What is Bitcoin mining? Bitcoin mining is a lot like a giant lottery where you compete with your mining hardware with everyone on the network to earn bitcoins.
