Digitimes today speculates on Apple's future Intel Chip roadmap. Basically they are saying that Snow Leopard's Grand Central feature sounds a lot like what Intel's Nahalem processor will be able to offer with more cores and more threads/core/cycle.
The main optimization Apple describes as a target for Snow Leopard is Grand Central, a technology it says will make all of OS X multi-core aware and optimize it for allocating tasks across multiple cores and processors. Apple also says Grand Central will make it easier for OS X software developers to create programs that make the most of multi-core platforms.
With the adoption of Nehalem, Apple's server and workstation configurations are likely to jump from eight threads (their current maximum) to 16 threads initially, with the potential to scale to 24 or more
