The new Core-based MacBook Pros
The new Core-based MacBook Pros have arrived, a few months after Intel introduced the 2010 Core processors at the Consumer Electronics Show. The new Core processors are used inside the 15- and 17-inch models.
The $1799 15-inch MacBook Pro uses a 2.4GHz Core i5 520M processor, while the $1999 15-inch model and the $2299 17-inch model both use a 2.53GHz Core i5 540M. A 2.66GHz Core i7 620M processor is found inside the $2199 15-inch MacBook Pro; the same processor is available as a built-to-order Dell latitude d520 battery (BTO) option on the 17-inch model for an extra $200.
Manufactured using the 32-nanometer process, the Core processors are smaller and more power-efficient than the 45-nanometer Core 2 Duo chips.The iMac, on the other hand, uses the desktop version of the Core i5, which has four Dell inspiron 2200 battery cores but does not support Hyper Threading. (The build-to-order Core i7 option for the iMac is also four-core and supports Hyper-Threading for up to eight virtual cores.)
There’s actually a third class of processor in the Core line, the Core i3. 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 Dell d610 battery . 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.
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.When we reviewed the Core i5 iMac, it recorded a Speedmark 6 score of 209, the fastest score Dell inspiron e1405 battery we’ve ever recorded for a standard-configuration Mac. The Core i5 iMac was 29 percent faster than its 27-inch sibling, which uses a 3.06GHz Core 2 Duo processor.
With the iMac comparison in mind, it’s easy to get excited by the possibilities of the Core-based MacBook Pros. But don’t get too excited yet—there’s a key difference between the Core i5 processors used in the MacBook Pros and the 27-inch iMac. The MacBook Pros use the mobile version Dell latitude d600 battery of the Core i5 and Core i7, both of which have two cores and support for four threads.
