The only thing holding back ARM from dominating all the segments beyond smartphones is software. Microsoft is the key to ARM moving beyond smartphones into the enterprise and desktops. Microsoft is throwing its weight behind ARM and we will see the results over the next 5-10 years.
I would like to see AMD eventually release K12 or an improved version from what they originally started designing. Jim Keller hinted that K12 had a bigger engine than Zen. We already see Zen keeping up quite well with Broadwell (only slightly behind overall ). K12 could easily be the fastest custom ARMv8 core available even ahead of Apple's custom cores. K12 is likely to sport SMT as AMD has experience now with SMT designs. K12 could make for some very impressive ARMv8 server SoC . If AMD sees enough traction for ARM it will eventually be forced to launch K12.
