Haswell-equipped 13-inch MacBook pops up at Geekbench
Benchmarks for two unreleased Macs have appeared in Primate Labs' Geekbench database. Perhaps most significant is a 13-inch MacBook Pro, listed with an "AAPLJ44,1" codename. The benched model is equipped with a 2.4GHz Core i5 4258U dual-core processor, 8GB of RAM, and a Boot ROM dated June 5th. It's also running a proprietary build of OS X Mavericks, 13A2050.
In tests the computer ranks roughly 5 to 8 percent faster than current low-end MacBook Pro models. As with the new MacBook Air, the new MacBook Pro is liking trading off any major performance gains for greater battery life. Intel's Haswell platform, on which the Air is based, is oriented more towards power efficiency than speed.
It's unclear if the J44,1 unit is Retina-equipped or not, since the extra resolution would have little impact on performance. Apple is rumored to be phasing out non-Retina MacBook Pros. When a refresh might take place has yet to be announced.
The other new benched Mac is thought to be the cylindrical Mac Pro. At Geekbench the unit is identified only as the AAPLJ90,1, running a 13A2054 build of OS X Mavericks. Specs include a 2.7GHz 12-core Xeon E5-2697 v2 processor, paired with 64GB of RAM.
Performance is said to vary depending on the task, ranging from slight improvements over 2012 Pros to major ones. The best performance is reportedly found in single-core operations and in memory. "Apple's claim of 'up to 2x faster' floating point performance may be optimistic," cautions Primate Labs' John Poole. "The new 'Ivy Bridge' Xeon processor in the new Mac Pro has instructions that can process twice the amount of data as the 'Westmere' Xeon processors in the current Mac Pro. The problem is that only certain kinds of software can take advantage of these instructions."
