UPDATE 4/3/10 2:30PM Eastern: Added mention of IPS display panels to specs page.
For about 3 months now, Intel’s new “Arrandale” mobile Core i3/i5/i7 processors have been on the market — offered by many of the major PC makers in their latest laptops — but have not yet been integrated into Apple’s products. These CPUs are part of Intel’s “Nehalem” family, a major generational leap from previous Core 2 technology. Nehalem-class chips have been at the heart of the Mac Pro and quad-core iMacs for some time, and offer numerous advantages.
Arrandale, though only a two-core design versus the quads in current Core i5/i7 desktops, is ahead of those desktop chips in a few areas. Notably, it is one of Intel’s first Nehalem chips built on a 32-nanometer manufacturing process; each step in shrinking silicon chip manufacturing processes brings about greater energy efficiency, better price/performance, and allows more transistors to be packed onto a smaller chip footprint.
