Between Intel entering the GPU market, pricing their 12 series CPUs more competitively, and entering the ASIC miner market I can't tell if this is part of some grander strategy or if they're really just trying everything to see what sticks. Also, with Nvidia and AMD both having released mining specific cards last year and Intels planned foray I can't help but think PoW isn't going anywhere for years to come. Surely nvidia and AMD both know that ethereum devs plan to do away with proof of work by summer?
