However, like the previous generation, the 15-inch MacBook Pro features switchable graphics-this time with an integrated Intel HD Graphics 3000 GPU.Īs with the last generation of MacBook Pros, users no longer have to log out or suffer through a few seconds' delay while the notebook switches chips the changeover is now seamless and instantaneous. On our 15-inch model, the Nvidia GeForce GT330M chip was replaced with an AMD Radeon HD 6750M and 1GB of DDR5 memory. That's 46 seconds faster than the category average.įor the latest generation of MacBook Pros, Apple has switched from Nvidia to AMD GPUs. The program, using the AMD GPU to accelerate conversion, took 1 minute and 24 seconds to complete the task.

We then used CyberLink MediaEspresso to convert a 5-minute 1080p video to an iPod touch format. It took the new 15-inch MacBook Pro just 37 seconds, 10 seconds faster than the previous model, and 45 seconds faster than the average. The benefits of the built-in media encoder on Intel's second-gen Core processor were also evident when we transcoded a 114MB MPEG-4 to AVI using Oxelon Media Encoder. That's about 12 MBps faster than the category average. In OS X, we duplicated a 4.97GB folder of multimedia in 2 minutes and 20 seconds, a rate of 36.4 MBps.

The15-inch MacBook Pro's Geekbench score of 10,874 was double the previous generation (5,422).īooting into Mac OS X 10.6 took the 750GB hard drive a speedy 44 seconds, the same as the previous generation. The only systems that scored higher-and cost less-had SSDs: the Lenovo ThinkPad T410s (11,264) and the Sony VAIO Z (9,475). After installing Windows 7, we ran PCMark Vantage in Boot Camp and saw a score of 7,648 that's tops in the 15-inch notebook category, whose average is 4,764, and about 1,000 points higher than the previous MacBook Pro (6,699). Our 15-inch MacBook Pro came with a 2.2-GHz Intel Core i7-2720QM processor and 4GB of RAM. Like Windows-based notebooks, Apple is updating its laptops with Intel's second-generation Core processors. In a FaceTime call to another MacBook user, we both saw bright, vivid colors (the yellow on our caller's shirt really popped), and images were crisp and smooth.

While it's capable of sending 720p video, the system will only send a high-definition stream if the recipient's notebook can handle it. It defaults to portrait mode-a carryover from its phone days-but you can switch it to a landscape view. Also, the FaceTime app, first seen on the iPhone, now comes pre-loaded on the MacBook Pro. The memory card slot has been updated to accept XDHC cards, which means higher speeds and capacity.Īpple has updated the webcam in the 15-inch MacBook Pro to support a 720p video. Built into the left side are two closely placed USB 2.0 ports, Mini DisplayPort (shared with Thunderbolt), a FireWire 800 port, the MagSafe power port, and headphone and mic jacks.
Otherwise, the ports remain the same: On the right side of the 15-inch MacBook Pro you'll find the 8X SuperDrive and Kensington lock slot. While there are no peripherals that yet support this interface (the earliest will be this summer), Apple provided a demonstration where it was able to duplicate a 4.42GB folder in 10 seconds.

Thunderbolt will also let you daisy-chain up to six devices, so you can have several hard drives connected to an external monitor, which should please movie editors who like to use larger displays. This port also carries up to 10 watts of electricity, so you can use Thunderbolt peripherals, such as external hard drives, without having to plug in an extra source of power. This connection, which shares the same port as the Mini DisplayPort, has theoretical throughput of 10 Gbps. The newest addition to the MacBook Pro's ports is Thunderbolt, formerly known as Light Peak. Higher tones were crisp without sounding distorted lower notes, such as the bass line in the song, had enough presence, though we would prefer a little more punch.
