The new Mac Pro isn't supposed to launch until later on this year, but Geekbench has nabbed a new set of benchmarking tests which appear to be from the new machine itself. The computer is labeled as "AAPLJ90,1" in the report, which seems strange, considering that a retail build would probably be listed as "MacPro6,1." But perhaps that "J90" is a code name of some sort, suggesting a pre-release build.
The machine in question is running a 12-core processor, and 64 GB (!) of RAM, along with a pre-release build (Build 13A2054) of OS X 10.9, which we now know as OS X Mavericks. The motherboard ID also matches one known to be in the new Mac Pro, so it's likely this set of benchmark results is legit, though it might not match up to a final release of the machine.
And what's the verdict? It's fast, of course. Significantly faster, in places, than a current 2012 Mac Pro build. Of course, Apple bragged during WWDC 2013 that the latest model would be "up to 2X faster" than previous Mac Pros. While that might be true for some applications, this machine doesn't meet that figure consistently. Still, considering this is probably an early version that's less than fully optimized, there's no doubt at all that the new Mac Pro will be a very slick machine indeed.
