AMD did actually in February-MarchYeah, it's been half a year since this "sure thing" fresh shit was first aired, and I still see nothing but dried-up shit.
The only reason Intel licensed Nvidia's patents was part of case settlement payout, and I'm sure that settlement included no more suits from Nvidia (or they would have continued the license deal).
If Intel doesn't fear other GPU vendor's patent portfolios, then I don't see them wasting the money. Everyone assumes they're in for a "world of hurt," but how many GPU companies aside from Nvidia went on the patent warpath recently?
...Snip.
