AMD AMD announced plans to introduce a desktop PC processor with three cores in the first quarter of 2008. The three-core chip will carry the same Phenom brand name that AMD plans to attach to its quad-core desktop chips due to ship to PC companies by the end of this year.

The difference between 3 and 4 cores for the average user would be negligible at best.


While this is true for the average user, this is an ideal solution for the cost-sensitive software developer.

With two cores it is relatively easy for a developer to implement a concurrent algorithm that works correctly for two concurrent threads, yet fails miserably for three or more. In contrast, however, those algorithms which work for correctly for three threads almost always (a) work for any number of threads (subject to performance scalability issues), or (b) appear on their face to be specifically limited in the number of concurrent threads which are correctly supported.

With three cores, a developer will be able, much more efficiently, to catch and repair such errors before release. Once such machines are released, I would expect them to be targeted towards developers writing concurrent software.
