In testing, the 2011 models generally match or outperform the 2010 models. The new models are rated at 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.Īpple has improved AirPort performance by building three WiFi antennas into the 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.

This is the second MacBook Pro generation with Thunderbolt, a 10 Gbps data connection that uses the same connection as Mini DisplayPort. The Late 2011 MacBook Pros ship with OS X 10.7 Lion, but because this is a relatively minor revision, they should be able to run Mac OS X 10.6 Snow Leopard. The best news of all is that with faster CPUs, larger hard drives, and improved graphics, there’s no change in price. There had been some speculation that the next MacBook Pro revision would include the same Bluetooth 4.0 built into the iPhone 4S, but no such luck – we’re still living with Bluetooth 2.1 + EDR. The graphics processor (GPU) has been upgraded to Radeon HD 6750M on the base model and 6770M on the faster 15-incher, and the base model now has 512 MB of dedicated video memory, up from 256 MB in the Early 2011 version. In addition to slightly faster CPUs, the Late 2011 model comes with 50% more spacious hard drives – 500 GB instead of 320 GB on the base model and 750 GB (up from 500 GB) on the 2.4 GHz version. The top-end version goes from 2.2 GHz to 2.4 GHz, a 9% improvement. The 15″ model advances from 2.0 GHz to 2.2 GHz, a 10% speed bump. The Late 2011 MacBook Pros represent a small step forward from the Early 2011 models introduced 8 months earlier.
