Apple likes Intel’s desktop line of Core i5 and Core i7 CPUs well enough to put them in their iMacs, so it makes sense that they would want to avail themselves of Intel’s three new Core i5 and i7 mobile CPUs (codenamed Arrandale) for any forthcoming refresh of the MacBook line. But things may not be that simple.
One way the Arrandale line of processors differs from previous Intel mobile CPUs is that the chips include mandatory integrated graphics. According to the Bright Side of News, Apple’s not interested in that: even the most inexpensive Macs now contain NVIDIA GeForce 9400M GPUs, which offer far superior performance to integrated graphics solutions.
