The purported Mac Pro popped up on Primate Labs' Geekbench Browser on Wednesday, carrying model number "AAPLJ90,1" and an impressive hardware spec sheet, including the 12-core Intel Xeon E5-2697 clocked at 2.70GHz, and 64GB of speedy 1867 DDR3 RAM.
It is possible that the machine's name and model number were spoofed, but as MacRumors notes, the system is running build 13A2054 of OS X 10.9 Mavericks, which is a different iteration than the developer preview Apple seeded earlier in June. Also lending to the computer's authenticity is a motherboard identifier previously associated with the new Mac Pro.
As for performance, the machine achieved a 32-bit Geekbench score of 23,901, compared to Apple's current top-of-the-line Mac Pro which scored an average of 21,980. The current high-end model is also running a 12-core setup, but with a pair of six-core Westmere family Xeon CPUs clocked at 3.06GHz.
The Geekbench appearance is the first of what will likely be many such sightings leading up to the Mac Pro's launch "later this year."
