Despite this huge upswing in interest, it's not an area that AMD sees its future, which it's insisting is still the gaming market. During the call, CEO Lisa Su said that the company had seen some "elevated demand," but that it's not "looking at [cryptocurrency] as a long-term growth driver." That's despite some of its partners, like ASUS, producing dedicated currency-mining cards that are better tweaked for constant use.

Of course, cryptocurrency is essentially a computational arms race, with the person with the most power liable to win. That has led to some outlandish -- and unverifiable -- stories, such as Quartz reporting that Marco Streng claiming he has chartered a Boeing 747 to ship graphics cards to his digital mining facilities. As that report elaborates, the current Etherium boom is worth around $7.2 million a day, although with all bubbles, it remains to be seen if the investment will provide a decent return.
