kudos for the engineering efforts... but Family 15h wasn't exactly known for stellar low power or impressive efficiency

neither Steamroller's adaptive clocking nor AMD's change from the initial power-plagued 4-wide FPU to the subsequent less-performant 3-wide FPU managed to enable that whole line of construction equipment to dig itself out of a hole -- instead it took calm reflection to rediscover a state of Zen :)
