Preview at WWDC likely in June, followed by September launch.
13-Inch Retina MacBook Pro Once Again Shows Up in Benchmarks
While much of the data presented to Geekbench by machines can be faked and many Hackintosh enthusiasts go to great lengths to match their machines' details to those of actual Macs, the details of the MacBookPro10,2 were consistent enough with expectations that both we and Geekbench developer Primate Labs believed the entry to be genuine.
Following the original entry, a second MacBookPro10,2 has now appeared in the results database, with the data bearing very strong similarity to the original entry but with some differences that suggest this entry may also be legitimate.
Like the machine that appeared first, the new machine runs a 2.9 GHz Core i7-3520M, the same processor found in the current high-end model of the non-Retina 13-inch MacBook Pro. The machine's motherboard identifier also matches the previous machine, which itself matched a previously unaccounted for identifier seen in early developer builds of OS X Mountain Lion. And as would be expected for machines running the same specs, the two machines have very similar Geekbench scores of roughly 7800.
There are a few differences, however, with one of the key ones being a custom 12A2066 build of the unreleased OS X 10.8.1. Just two days ago, Apple gave the first indication that it will begin seeding OS X 10.8.1 to developers, but it has yet to do so. In addition, the four-digit build number suffix is sometimes used internally by Apple on its test machines, although such four-digit build numbers are sometimes also used publicly for special builds such as the version of OS X 10.7.4 that shipped on new 15-inch Retina MacBook Pro models.
In addition, this new entry reflects a MacBook Pro with 8 GB of RAM, in line with what ships paired with the Core i7-3520M on the corresponding non-Retina model. The previous MacBookPro10,2 entry showed a machine with only 4 GB of RAM. Finally, the BIOS string for the new entry appears to show an updated date code of July 18, 2012, compared to the previous one registering as June 11, 2012.
Geekbench results have on several occasions revealed upcoming Mac models, most recently in mid-May with the MacBookPro9,1 that turned out to be the non-Retina 15-inch MacBook Pro upon its release the following month. Notably, an iMac13,2 entry that also appeared to be legitimate surfaced around the same time, but Apple has yet to release updated iMacs.
