By published data, Intel 45nm, with products out in 2007, switches as fast as TSMC 28nm, with products out January this year.
They only have ~2 years of advantage on density, but they reliably have 5+ years advantage on speed. I'd call that extreme.
I absolutely believe that once Intel actually releases atom cpus on their best process (so far, they have mostly used them to fill out production on old processes), it will beat ARM on performance/watt. When they move atom to a competitive uarch (OoO ffs), the race will stop being a race.
That's indeed what I was referring to. Intel's processes are typically superior to AMD/GloFo's at the same node, and miles beyond the respective bulk processes at TSMC. They also get there first.
