The 2.7GHz Core i7 MacBook Pro was 36 percent faster in our iTunes test and 28 percent faster in our Handbrake test.
The next step up in the line, the 13-inch 2.7GHz dual-core Core i7 MacBook Pro, showed improvement that was less dramatic, scoring only a 13 percent gain over the model it replaces, a 13-inch 2.66GHz Core 2 Duo MacBook Pro. In the Handbrake test, the 13-inch 2.3GHz Core i5 MacBook Pro finished 47 percent faster. The biggest leap in performance was in the iTunes AAC-to-MP3 encoding test, which was 57 percent faster on the 13-inch 2.3GHz Core i5 MacBook Pro. The new 13-inch 2.3GHz dual-core Core i5 MacBook Pro, with a Speedmark 6.5 score of 140, was 35 percent faster than the 13-inch 2.4GHz Core 2 Duo MacBook Pro it replaces. To measure the overall speed of each MacBook Pro, we used our system performance test suite, Speedmark 6.5. MacBook Pro (Early 2011): Speedmark 6.5 scores When Thunderbolt peripherals become available, Macworld Lab will revisit the speed claims with our own benchmark tests. Several Thunderbolt-equipped products have been announced, but they’ve yet to start shipping, so at the moment it’s impossible to fully test the Thunderbolt port. Apple and Intel are hoping for widespread adoption of Thunderbolt, but only time will tell if Thunderbolt will catch on. Thunderbolt can supply up to 10 watts of power per channel and offers speeds of up to 10Gbps, twice that of USB 3.0 and 12 times as fast as FireWire 800. You can daisy-chain up to six devices to the Thunderbolt port. The port looks identical to the Mini DisplayPort and you can connect Mini DisplayPort adapters or Apple’s LED Cinema Display ( ). It’s now a Thunderbolt port, a new connectivity technology. The only change you’ll notice to the exterior of the MacBook Pro is the tiny lightning bolt icon near what was once the Mini DisplayPort connector.

Apple says that these processors are free of this defect. Intel discovered a hardware problem that could possibly slow down performance over time in the first Windows-based Sandy Bridge computers, and recalled those processors. The Sandy Bridge processors are using Turbo Boost 2.0, which Apple says is more efficient than the previous version. Another technology, Turbo Boost, allows the processors to temporarily speed up when needed. Like its predecessors, the Sandy Bridge processors support Hyper Threading, which allows the system to address four virtual cores in the 13-inch models and eight virtual cores in the 15- and 17-inch models. With the new HD Graphics 3000 processor, Apple found the performance good enough to finally invite the 13-inch models into the new Core era. With the older 13-inch MacBook Pros, Apple didn’t think the Intel HD graphics available at the time were powerful enough to be the only graphics option, so it stuck with Core 2 Duo processors and used Nvidia’s integrated GeForce 320M graphics. The GT 330M kicked in for graphically intensive applications. In the previous generation of MacBook Pros, Apple used Intel’s integrated HD graphics only in the higher-end models, which also had a second, discrete GPU, the Nvidia GeForce GT 330M. The Sandy Bridge processors feature Intel’s HD Graphics 3000 integrated graphics processor. With the processor, cache, integrated graphics, and memory controller all residing on the same die, the Core i5 and Core i7 processors helped propel the new MacBook Pros well past their predecessors in CPU performance.

Intel’s latest Core series of processors, known by the code-name Sandy Bridge, are found inside every new MacBook Pro.
The $2499 17-inch model has the same specs as the $2199 15-inch MacBook Pro. The $2199 15-inch model has a 2.2GHz quad-core Intel Core i7 processor, a 5400-rpm 750GB hard drive, and a 1GB AMD Radeon HD 6750M discrete graphics processor. The $1799 15-inch model has a 2GHz quad-core Intel Core i7 processor, a 5400-rpm 500GB hard drive, and a 256MB AMD Radeon HD 6490M discrete graphics processor. The $1499 13-inch model has a 2.7GHz dual-core Intel Core i7 processor and a 5400-rpm 500GB hard drive. The $1199 13-inch model has a 2.3GHz dual-core Intel Core i5 processor and a 5400-rpm 320GB hard drive. The new MacBook Pro line consists of five models, all with 4GB of 1333MHz DDR3 memory, and Intel’s integrated HD Graphics 3000 processor. It all translates into performance jumps that were worth the wait. That’s a longer-than-usual gap between updates, but the new MacBook Pros sport several changes under the hood, including new processors, new graphics processors, and a new peripheral connector. It’s been nearly a year since Apple refreshed its MacBook Pro line.
