There's pretty much zero chance ARM will ever reach performance parity with x86 But do workstations need state of the art performance? Once upon a time, they did. Today they don't, but are only behind by a small factor. That gap may grow to a few orders of magnitude some day, especially if all the performance advances come from multi-core, which workstations have a hard time exploiting fully. Maybe Apple sees the desktop performance requirements leveling off enough for ARM to catch up. It's not hard to imagine the laptops of tomorrow being in the same performance class as phones and tablets.
