By wafer doesn't sound like the correct comparison as we mostly care about top nodes for this. Revenue actually sounds better to correct for that. Your link also shows that Intel sells their old nodes to others further skewing the per-wafer comparison. Wafers at 14nm or better would probably be a good metric for who has the volume behind top nodes to then be able to stay in front. If that's TSMC by a large margin losing the mobile and GPU markets has really done a bigger number on Intel than I had assumed before.
