No; you cannot compare processors from different generations that way. Which quad core I7 processor are you referring to? There is the first generation quad core I7 processor and the new second generation sandybridge quad core I7 processor, released only 2 months ago.
Although the duel core processor you mentioned has higher clock speed, that doesn't mean that it is faster; clock speed isn't the only thing that determines a CPU's overall performance. Things like the number of cores (the higher the better), the size of L3 cache, whether the CPU supports turboboost 2.0 technology or not, how many threads the CPU can support at once are also contributing factors of the CPU's speed. Essentially, the quad core I7 processor is a lot faster than the duel core one. There are other things like a more powerful integrated GPU Chip which makes them so much faster, but I won't go into detail here. -----Original Message----- From: macvisionaries@googlegroups.com [mailto:macvisionaries@googlegroups.com] On Behalf Of Kliph&Sharrie Sent: Friday, April 15, 2011 1:01 AM To: macvisionaries@googlegroups.com Subject: macbook pro specks? So, shopping around a little bit for what I might want. And I see that the 15.4 model macbook pros have a i7 quod core processor, and the 13.3 has a dool core. Now on the quod core the processor is listed at 2.2 GHZ, and on the dool core it's listed at 2.7 GHZ, both with 4 gigs of ram. Does that make them about the same speed? -- You received this message because you are subscribed to the Google Groups "MacVisionaries" group.
