Heard from a guy who owns a large farm, he has connections in the industry for GPUs and other computer components. He basically said that AMD is very difficult to source unless you know someone high up.
But NVIDIA on the other hand will never be out of supply of their GPUs. They are loads and loads of 1060, 1070, 1080 and NVIDIA predicts the supply will never dry up.
So here is proof that the difficulty gains will still keep climbing...
You haven't been looking at recent availability AND PRICING on the GTX 1070 have you?
Pricing solidly into 1080 territory and STARTING to enter 1080 ti territory, WHEN YOU CAN FIND THEM AT ALL.
The GTX 1060 is also starting to get into gouge-level pricing and availability is dropping.
The GTX 1080 and 1080 ti seem to be unaffected so far in the US, as they aren't all that good at ETH mining, but ZEC miners (and miners of some small-cap coins like DGB via the Skein or Groetsl algos) find them attractive, so I can see them starting to get hit as well.
How is it AMD being "noob" when they get hit out of nowhere by a sudden spike in demand for their cards?
They can't just wave a magical wand and suddenly have tons more, it takes WEEKS and sometimes MONTHS for a chip order to go from "order accepted" to "chips are delivered" - then add some more time for getting the chips to the card makers and card assembly and delivery to the end-sellers.....
They also have to worry about not OVERPRODUCING for when the demand spike ends and there's suddenly a ton of used cards clogging up sales for new cards - which oddly enough NVidia has already stated they're concerned about, as they're getting hit TOO this time around (unlike 2013/2014 Litecoin/X11 craze when NVidia cards weren't even close to being competative on the algos in use).
I strongly believe that the whole "overproduce" issue is WHY Nvidia has decided to do "mining specific" cards at all - those aren't going to clog things up when the mining boom ends, as gamers aren't generally going to have interest in a card with no video outputs (though folks that play DirectX 12 games might have interest in them as a SECOND card, that's a fairly small part of the market).
