I'm going to be honest, 700k isn't a whole lot when it comes to GPU sales. That's not even 1% of 2018's total sales and only 21% of Q4's total sales(revenue of 2.8 billion dollars), even assuming every GPU sold was 850 dollars(they weren't, most were way cheaper) that's still 3.29 million GPUs sold. Assuming a more sane average selling price of 350 dollars, you raise that to 8 million GPUs, which drops things down to 8 percent. That's for a single quarter, and a quarter where demand was really bad.
