New 21.5-inch Retina 4K models expected.
Apple Launches MacBook Pros with Thunderbolt, Quad Core CPUs, AMD GPUs
While not all the rumors leading up to the launch were true, many of the last minute leaks were accurate, and Apple still managed to sneak in a few surprises.
Apple launched the new MacBook Pros this morning after much anticipation. For the first time ever, Apple has included Quad Core CPUs into their notebooks. The 15" and 17" models offer Quad Core CPUs using the Intel 2.2GHz Quad Core 2720QM and 2.0GHz Quad Core 2630QM. While many applications may not take advantage of all 4 cores, these new Sandy Bridge processors include Intel's Turbo Boost 2.0, which should increase the speed of the remaining cores when the others are underutilized.
Intel Turbo Boost Technology 2.0 automatically allows processor cores to run faster than the base operating frequency if it's operating below power, current, and temperature specification limits.The maximum Turbo clock speeds for the 2720QM and 2630QM are 3.2GHz and 2.9GHz respectively.
Apple has also introduced a hybrid Thunderbolt/mini Display port on the new MacBook Pros. This represents Intel's Light Peak technology which is said to offer high speed connections and is expected to replace the need for USB 3.0. We expect to hear more about it this afternoon at Intel's press conference. From Apple's PR:
"Thunderbolt is a revolutionary new I/O technology that delivers an amazing 10 gigabits per second and can support every important I/O standard which is ideal for the new MacBook Pro."Apple has posted a page dedicated to Thunderbolt.
