The new hexacore 2010 Mac Pros have been filtering in over the past few days to the first lucky customers. Here is a set of unboxing pictures fromin Japan. They show the Mac Pro, the SSD drive, ATI Radeon 5870, and new Hexacore Xeon CPUs.

Additional photos and notes are summarized here:

- 64-bit kernel is now default for the 2010 Mac Pros

- Unboxing photos from OWC

- More photos from the forums

- OWC confirms that the new Mac Pros can support up to 64GB of RAM

- Early Cinebench and Geekbench benchmarks for the 2010 Mac Pro

- Portal (game) benchmarks.

The early benchmarks predictably show that in Geekbench and Cinebench, the 12-core Mac Pros see a significant benefit. Of course, the benchmarking tools are optimized for multi-core support. On the other extreme, Portal benefits little from the additional cores. Of course, real life results will likely fall somewhere in between depending on your particular software needs.
