A64 represents some sort of inflection point and that Intel is very likely to be damaged severly in just the next few months to a year."
That's it exactly. The debatable question is how much Intel will be damaged and how effectively they can/will come back.
The current situation is reminiscent of the early days of Willamette vs Athlon. The main difference is back than AMD had a big cost advantage because Athlon was a bulk CMOS chip a little over half the size of Willamette. Now it once more enjoys a modest performance advan- tage over Intel on the desktop but with a significant cost disadvantage. AMD didn't "damage" Intel materially in 2002 and will have a much smaller effect this time.
