Apple’s 45nm Refresh: New MacBook & MacBook Pro

Final Words

The new MacBook and MacBook Pro, much like the MacBook Air before them, are much more functions of Intel's innovation rather than Apple's. In the case of the new MacBook and Pro models, the innovation is almost exclusively limited to what Intel has been able to do with mobile Penryn as Apple made no changes to the exterior of either system.

Regardless of where the innovation comes from, it is still an improvement in technology and mobile Penryn proves to be everything we expected it to be. The biggest improvement by far comes in the battery life department. Just as we had seen earlier, you can expect these new models to outlast their predecessors by a good 7 - 15%.

The performance side of things is more of a mixed bag. There are some situations where Penryn is clearly faster than Merom while others show the two with equal performance. It's for this reason that we say the biggest improvement lies in battery life, not performance.

Apple picked the right CPU partner in Intel, as it seems that every year we get good increases in either performance, battery life or both.

If you're holding out for something more revolutionary you may want to wait for Montevina later this year, or Nehalem sometime next year. Both platforms will give Apple ample opportunity to make more changes to the design and featureset of the MacBook and MacBook Pro, all while improving battery life and performance.
