	An '''OpenCL miner''' is a ~~bitcoin miner~~ that uses the ~~[http://en.wikipedia.org/wiki/OpenCL~~ OpenCL framework] to perform ~~the [[hash\|~~hashing~~]] computations. When used with a modern GPU, this can produce hash rates orders of magnitude higher than what can be achieved with a CPU~~.		An '''OpenCL miner''' is a Bitcoin mining program that uses the OpenCL computing framework to perform SHA-256 hashing on GPUs or other OpenCL-compatible hardware.

	==~~Overview~~==		==Role in Bitcoin mining==

	OpenCL ~~is a computing framework which allows programmers to write code which works across a variety of hardware~~, ~~both CPUs~~ and ~~GPUs included.~~ OpenCL ~~was originally developed by Apple~~.		OpenCL miners were important during the GPU mining era. GPUs were once much faster than CPUs for Bitcoin hashing, and OpenCL made it possible to use compatible AMD/ATI and other devices for mining.

	The ~~use of an~~ OpenCL ~~miner allows one to hash using a~~ GPU ~~(Graphics Processing Unit)~~, ~~which has a vastly larger ability to perform algorithmic calculations~~ than ~~an CPU~~ (~~Central Processing Unit~~).		General-purpose CPU and GPU mining is no longer practical for ordinary Bitcoin mainnet mining. The Bitcoin network's mining difficulty and hardware market are dominated by specialized SHA-256 mining hardware. OpenCL mining remains useful for understanding Bitcoin mining history, GPU hashing implementations, and some non-Bitcoin proof-of-work systems.

			Modern mining software and pool infrastructure use newer interfaces than the early <code>getwork</code> and RPC-miner workflows. Bitcoin Core's current mining RPC documentation lists <code>getblocktemplate</code>, <code>getmininginfo</code>, <code>getnetworkhashps</code>, <code>submitblock</code>, and related RPCs.<ref>{{cite web\|url=https://bitcoincore.org/en/doc/31.0.0/rpc/mining/getblocktemplate/\|title=getblocktemplate (31.0.0 RPC)\|publisher=Bitcoin Core\|accessdate=23 June 2026}}</ref><ref>{{cite web\|url=https://bitcoincore.org/en/doc/31.0.0/rpc/mining/getmininginfo/\|title=getmininginfo (31.0.0 RPC)\|publisher=Bitcoin Core\|accessdate=23 June 2026}}</ref>
