AMD Jumps to 12-core Chip, Skips 8-core Chip Plans
Multi-core, shmulti-core.
Intel has already built an 80-core prototype (back in 2006, I believe) running at 3.xGHz per core.
The Cell processor from Sony/Toshiba/IBM has 8 cores and is in the PS3. Toshiba is going to be using it in other consumer devices as well.
So far, the use of multi-core CPUs requires that software be multi-threaded and optimized to take advantage of additional cores, otherwise they merely exist and contribute little to performance otherwise. Only now are we actually starting to see their utilization beginning to happen.
Let's not forget that most people are still using a 32-bit OS. 64-bit exists, but like multi-core CPU technology, there's not really a lot of things coded to take advantage of it (but it is indeed faster).
Until the next "big leap in computing" comes along, these two things will have to fill our current need for speed.
Funny thing about AMD's 12-core CPU -- it's being built using the same method for which they criticized Intel. PKB
