just announced at the developer conference:
http://www.apple.com/macpro/Inside every Mac Pro resides two new Dual-Core Intel Xeon Woodcrest processors. Running at up to 3GHz, they bring industry-leading, 64-bit, quad-core performance to every Mac Pro.
Augmenting the speed delivered by the processors, the system architecture features 1.33GHz dual independent front-side buses that maximize the performance of the dual-core, dual-processor system and deliver maximum processor bandwidth of up to 21.3 GB/s. The Dual-Core Intel Xeon processor also offers an enhanced SSE3 vector engine. Capable of delivering 128-bit vector computations in a single cycle, the SSE3 vector engine accelerates data manipulation by simultaneously applying a single instruction to multiple data ideal for transforming large sets of data, such as applying a filter to an image or rendering a video effect.
All Mac Pro workstations support a new, fully-buffered memory standard that allows for more memory capacity, higher speed memory, and better memory reliability. You can install up to 16GB of 667MHz DDR2 fully-buffered Error-Correcting Code (ECC) memory in every Mac Pro system.
