“It’s fast, it’s simple, and it’s flexible,” said Apple’s Moody. It also allows users to daisy chain up to six devices together. The technology is based on the PCI Express protocol that most Macs use for internal I/O, but via adapters it can support pretty much any other type of connectivity protocol, including FireWire, USB, and Gigabit Ethernet. Co-developed with Intel, Thunderbolt has two bi-directional channels that can transfer data at up to 10Gbps each, a speed that’s 12 times faster than the theoretical maximum of FireWire 800. Apple is among the first vendors to be using the AMD Radeon HD 6750M, which it says can deliver up to three times better performance than previous technology.īut the newest feature on the MacBook Pros is a new connectivity technology called Thunderbolt. As with previous models, the system will automatically switch to the higher-power chip when using more graphics-intensive applications. Graphics also got a revamp in this version, with the 13-inch models sporting an integrated Intel HD Graphics 3000 chip that’s part of the Core architecture the 15-inch and 17-inch versions featuring both the Intel integrated chip and a discrete AMD Radeon HD processor with up to 1GB of memory. Intel refers to the processors used in the new MacBook Pros as its “second-generation of Core i processors” during development, they were codenamed “Sandy Bridge.” Earlier this year, Intel discovered problems in the chipset of Sandy Bridge processors that were shipping, but Apple vice president of worldwide Mac hardware marketing David Moody told Macworld that the company was using the latest updated versions, which corrected the flaw.
