Apple’s refresh of the iMac line today no doubt left some rival manufacturers scratching their heads over how Steve Jobs and Co. got early access to the X9100 3.06GHz Centrino 2 chipset. Not scheduled to be launched until June, the CPU – aka Montevina – will have a 1,066MHz front-side bus, compared to Santa Rosa’s 800Hz. Turns out, the answer is that Apple didn’t get priority access; instead, Intel have tweaked an existing-generation CPU especially for the iMac.
