AMD's chips are slow to market

Quote

Intel will up the stakes later this quarter with a 3GHz Pentium 4 containing Hyperthreading, a performance-enhancing technology that lets a chip handle more transactions simultaneously, similar to how a two-processor computer works.

Still, the performance race is somewhat theoretical from a consumer's perspective. In recent months, AMD has announced chips but then released them later and in lower quantities than initially expected. In the first half of the year, AMD announced chips the same day that PC makers began to sell computers containing them.
