My gut feeling is that Intel is coming back from its multiyear product inferiority vs. AMD. This ZDnet article lays out the case in much more detail than I could, but I have two observations to add:
1. There’s no reason Intel shouldn’t be able to leapfrog AMD. Permanent loss of market leads tends to be due to factors such as platform shifts or incurable code bloat; none of those seem to be present in the case of microprocessors.
2. For a while, I’ve been dealing with software and appliance vendors that like Intel because they’re paid to like Intel, via various kinds of marketing arrangements. But over the last few months, the liking has begun to sound a lot more sincere.
Disclosure: Intel is a co-sponsor of two of my white papers. Wiseasses might suggest that my point #2 above is therefore actually somewhat recursive in its reasoning.
