Thunderbolt can be used for video, hard drives, and networking, and adapters let you connect FireWire and USB devices.Īpple has improved AirPort performance by building three WiFi antennas into the Early 2011 MacBook Pros, allowing three channels with 150 Mbps bandwidth for a maximum bandwidth of 450 Mbps. Thunderbolt is 12 times as fast as FireWire 800, over 20 times as fast as USB 2.0, and twice as fast as USB 3.0, which Apple seems in no hurry to adopt. The hot new technology for this generation is Thunderbolt, a 10 Gbps data connection that uses the Mac’s Mini DisplayPort. These dual-core mobile CPUs have a 3-4 MB Level 3 cache shared by both cores and, thanks to Turbo Boost architecture, should be significantly more powerful than the Core 2 Duo processors they replace despite a tiny change in rated CPU speed. The Early 2011 model migrates from the dated Intel Core 2 Duo to Intel’s newer Core i5 and i7 CPUs. Apple took some big steps forward with the refreshed 13.3″ MacBook Pro.
