AMD's processors are selling quite well, especially among those who are building their own computers, and are not tied to things like pre-existing supply contracts and uncertainty over brand recognition. Just look at Amazon's best-selling CPU list...

The top 6 best-selling processors there are currently all AMD parts, with only 2 of the top 10 being Intel processors. Granted, I'm sure there are many builders holding off on buying Intel until their next CPUs come out, but AMD is certainly on an upward trend in terms of CPU sales, and seems to be doing quite well financially. Of course, they don't have the same production capacity of Intel, and TSMC can't just build new fabs overnight, so it's unreasonable to expect AMD to match Intel in terms of overall CPU sales, at least in the short-term.
