It's a good point, but a little old in the tooth and not really fair apples-apples comparison Foundry to IDM. Intel's transistor density at "10nm" is closer to industry "7nm". Really, I think it was the desire to continue multi-patterning rather than go with ASML's expensive EUV equipment for a last generation. Bad bet!
