The future CPU architecture built around the Nehalem has been the key topic during the last IDF 2008. Hereafter is the roadmap of what will change in the future for our Mac.
- By the end of the year, the Mac Pro should evolve to Nehalem Xeon and its associated platform.
Beside the classical jumps in frequency, performances should dramatically increase thanks to several features:
- The QuickPath should replace the current system bus. With a larger bandwidth, it should allow a multipoint communication between all components, and in particular between CPUs.
- The memory bandwidth has also been massively improved by several innovations:
* A memory controller for each CPU, no need to go through a dedicated external chips
* Each CPU will have its own dedicated RAM modules, and could manage up to 9 units via 3 channels that can be used simultaneously.
* The use
