ASICs (Utility-specific built-in circuits) are particularly manufactured for one particular hashing algorithm. Subsequently, a Bitcoin ASIC utilizing SHA-256 won’t work for Litecoin or Dogecoin as they each use Scrypt. One instance for ASICs are the Butterfly bitcoin miners.

There are altcoins that additionally use SHA-256, similar to Freicoin, Peercoin or Namecoin. An summary could be discovered at altcoins.com.

CPU and GPU can be utilized for any Coin, however the variety of hashes can be completely different. A card mining SHA-256 (Bitcoin) at 10GH/s will produce a lot fewer hashes in Scrypt (Litecoin, Dogecoin), as a result of Scrypt is way more advanced.
