Following Apple's recent announcement of minor spec bumps in its Retina MacBook Pro line, Primate Labs has run the new devices through benchmark tests, finding slight jumps in performance for the new models.

Primate Labs ran the refreshed Retina lineup through its cross-platform Geekbench 2 benchmark utility. The developers then compared the refreshed Retina MacBooks' results against those of their predecessors.

The 13-inch model, which got a 100MHz bump in processor speed, saw a three to five percent jump in performance on the Geekbench 2 test. Likewise, the 15-inch model, which also got a 100MHz spec bump, saw performance improve between three and five percent. Primate Labs attributes the jump entirely to the new processors.
