Though it uses different chips, a look at the iMac could give us some insight as to the Core i5 and i7’s performance versus the Core 2 Duo. That’s a pretty hefty claim that we’re currently testing in our lab. But by how much? Apple says that the new 15- and 17-inch MacBook Pros can be up to 50 percent faster than the previous Core 2 Duo-based MacBook Pros. Performance: What to expectĬhances are that the new Core i5 and i7 MacBook Pros will outpace their predecessors. An Apple representative said that the Core i3 doesn’t match the combination of features found in the new 13-inch MacBook Pro’s Core 2 Duo chip. Apple, however, decided not to use the Core i3 in its 13-inch MacBook Pro, instead sticking with the Core 2 Duo processors at 2.4GHz and 2.66GHz, and Nvidia GeForce 320 integrated graphics. Considered a “first level” processor by Intel, the Core i3 is a dual-core processor available at 3.06GHz and 2.93GHz, and comes with Intel HD Graphics built in. There’s actually a third class of processor in the Core line, theĬore i3.
Manufactured using the 32-nanometer process, the Core processors are smaller and more power-efficient than the 45-nanometer Core 2 Duo chips.
