As before, it automatically switches between GPUs on the fly. These are the first Macs to use Intel HD 3000 Graphics, and for the first time it’s coupled with AMD Radeon HD graphics. In testing, the Early 2011 models generally match or outperform the 2010 models. The new models are rated at only 7 hours of battery power, down from 8-9 for last year’s models, due to changes in the way Apple measures battery life.
Thunderbolt can be used for video, hard drives, and networking, and adapters let you connect FireWire and USB devices.īase CPU speed is 2.2 GHz, and there’s a 2.3 GHz build-to-order option for those who demand the most power.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 may never adopt if Thunderbolt takes off. The hot new technology this generation is Thunderbolt, a 10 Gbps data connection that uses the Mac’s Mini DisplayPort. As with last year’s models, these CPUs support TurboBoost, which lets individual cores run beyond their rated speed, and hyperthreading, which lets the each core appear to the operating system as two cores. This was the last 17″ MacBook Pro. The Early 2011 15″ and 17″ MacBook Pro models moved from dual-core CPUs to quad-core, which makes them a lot more powerful despite lower clock speeds.
