090426 Sun AMD chips with six or more CPUs soon to appear

AMD is planning to release soon some chips with six or eight CPUs:

Advance Micro Devices (AMD) said this week it is releasing its six-core Opteron chip in June, well ahead of schedule, and plans to follow it early next year with a chip code-named Magny-Cours that will ship in eight- and 12-core models. After that, it plans a 16-core chip in 2011.

These seem oriented to computation clusters as other than massively parallel computations it is hard to imagine which applications can make use of that many CPUs.
