More modern look coming this fall.
Updated Mac Pro Benchmarks and Video of Internals
Compiled by Grimace
Since more of the new Mac Pros have been delivered, it seems some of the early benchmarks underestimated the 2.26GHz Mac Pro's performance in single threaded tasks. The latest numbers show that the new 2.26GHz 8-Core machines appear to have both single-threaded and multi-threaded performance equal to or better than the previous generation 2.8GHz 8-Core machines. Another set of benchmarks are also compiled in this graph by Tesselator.
Meanwhile, Engadget posted a nice video showing the internals of the Mac Pro including the new CPU and Memory drawer which can easily slide out of the chassis.
