I've been under the impression that all proof-of-work mining is now done by ASICs.

Then I saw [this article](http://www.cnbc.com/2017/06/06/amd-surges-because-bitcoin-miners-need-its-graphics-cards.html), that says,

> "AMD shares are surging with bitcoin because digital currency 'miners' need its graphics cards"

Is there any truth to this? Or just False News?

There are countless digital currencies in existence; every day new ones appear, are pre-released; ICO'd, or are ninja launched.

Bitcoin is SHA-256, which renders mining using CPUs and GPUs pointless because ASIC processors have been engineered; chips which serve only one purpose; that is to compute/solve/hash SHA-256, and because they are engineered to do only that; they are exponentially more efficient in doing so.

GPUs on the other hand are used to mine coins both by hobbyist miners and large scale GPU farms.

But they aren't mining Bitcoin; or any other SHA-256; they are mining coins either with new POW (Proof of Work) algorithms; or POW algorithms for which no ASICs have yet to be engineered (or are simply not public/available).

For GPU based setups; common algos are X11, X13, X15, Scrypt depending (as ASICs do exist for Scrypt but were not widely adopted); and many others.

If you only have a single GPU; there is really no point whatsoever in using it to mine a currency; unless it's your own clone that you're creating.

You can go on site's like NiceHash and rent mega power; based on bidding per / g/hash t/hash; and jump in and speculate on what coin may or may not be profitable to mine. One GPU simply wont cut it.

Or you could build GPU mining rigs; using a simple steel frame; a low end CPU processor; 4 GB of ram; run Ubuntu off a USB stick; and slap 4 or 5 GPUs on the motherboard using PCI-E Risers.
