So more hard choices, the Core i5 is only available in the iMac available November, but the MacBook Pro and the iMac will presumably get i7 in early 2010, so if can hold on, the i7 seems like a big release.
Tom’s Hardware reports on Intel’s plans to offer their first Core i7 (Nehalem) mobile processors by the fourth quarter of 2009. These 32 nm Arrandale processors will be suitable for notebook designs, and Tom’s Hardware speculates that we’ll see these in Apple’s notebooks:
It is highly probable that Apple will base new MacBook and MacBook Por units on 32nm Arrandale Core i7’s. With 2 cores and able to process 4 threads, the new MacBook models will be able to save even more power, thanks to the smaller fabrication process as well as optimized processor features.
Apple’s MacBooks and MacBook Pros, however, were last updated in October with the latest 45 nm Penryn processors. So the very next Apple notebook updates will likely come prior to the release of these processors.
The 32 nm process also represents a die-shrink over existing 45 nm-based Intel chips. The new 32 nm process is said to offer an estimated 22 percent performance boost according to Mark Bohr, an Intel senior fellow.
