I knew this was a horrible idea, but I hadn't even considered it fully yet.
Wasn't there a mining card out a number of years ago too though?
This idea to hobble their card for mining purposes to ensure supply for gamers is absolutely insane. I am also almost certain it won't last. Someone will find a workaround. Or they will realize how stupid of an idea it was. I'm betting someone breaks it first.
This makes an absolutely huge hole in the market as well though. I hope AMD look at their offerings in the future and put out a MASSIVE supply of whatever card they can put out in huge numbers that can become the new kingpin of the mining market. Either through hashrate, or even just through efficiency. If they can manage to get out something that just barely is in line with Nvidia even, but has greater resale potential, they win. Because miners don't just care about what the fasted card is, but their bottom line. If AMD can make a more economical card, they'll switch to AMD.
