tbh, I always read this as Intel doing some sales magic here.
Apple: "Hey, we're making a product that has a 15w thermal envelope, do you have anything?"
Intel: "Yes!"
(Unspoken: their products will throttle down to fit, in fact, they will try to run always at 99ºC so you always get the best performance! FEATURE!)
Apple: "uhhhh..."
Consumers: "HEH IS IT EVEN A PRO DEVICE IF IT DOESN"T HAVE <INTEL MARKETING BRAND TERM>?"
Apple: "UHHHH... Guess we'll do it ourselves"
