AMD's new  chips have been taken off the shelves as soon as they arrive because digital currency miners want lots of them to make money.  Nvidia has been doing well off the craze, but AMD is finding it difficult to get enough chips out there and this has caused GPU prices to rocket.

Nvidia wants to release graphics cards specifically designed for cryptocurrency. From a product listing on ASUS' website: "ASUS Mining P106 is designed for coin mining with high-efficiency components -- delivering maximum hash-rate production at minimum cost. ASUS Mining P106 enhances the megahash rate by up to 36 percent compared cards in the same segment that are not tailored for mining."

The new card is also engineered to be seriously durable, enabling 24/7 operation for uninterrupted coin production." The ASUS Mining P106 uses an Nvidia chip, according to the specifications page on the website. 

Nvidia, AMD and ASUS have not officially announced the digital currency mining cards, according to their website press pages. It is not certain when the cards will be available for sale. Nvidia is likely making the cards designed for this use so that the surging digital currency demand doesn't affect its ability to serve the lucrative PC gaming market.
