MacWorld has released new benchmark results for the latest generation of MacBook Pros
. They feature Intelís newest Core i5 and Core i7 processors better known by their code name Sandy Bridge and the results are impressive. Macworld ran their usual battery of speed tests on the latest MacBook Pros. The only exception to the testing was with the new Thunderbolt connection, as devices that use this new standard were not yet available in time for testing.
The latest MacBook Pros include Intelís newest Core i processors. These chips integrate many features that were once only found on separate chips. The processor, cache, graphics, and memory controller are all included on the same chip, which allows the processor to run more efficiently, increasing overall performance.
The graphics processors used in the latest MacBook Pros have also been upgraded because of the Sandy Bridge processors. All of the latest MacBook Pros now uses the Intel HD Graphics 3000 processor that uses 384 MB of RAM that is shared with the main memory. The 15 and 17-inch models also include graphic processors by AMD instead of NVIDIA, this time around.
The 13-inch entry-level MacBook Pro
received a score of 141 on the Speedmark 6.5 test. This translates to a 35% increase in overall performance. This model showed marked improvements in every category tested with the exception of the Call of Duty tests. It was only able to display 26 fps as opposed to last yearís model which was able to product 33 fps. Using Intelís integrated graphics processor instead of a dedicated graphics card, really brought performance down quite a bit. The upper level 13-inch MacBook Pro only saw a 13% improvement over last yearís model, even though it uses the fastest dual-core processor that Intel currently makes, the 2.7 GHz Core i7 processor.
The 15-inch MacBook Pro
using a 2.0 GHz Core i7 quad-core processor, saw a 33% increase in speed over last yearís model. The next model 15-inch MacBook Pro using a 2.2 GHz Core i7 quad-core processor, saw a 38% increase over last yearís model. Itís not surprising that both computers scored so closely during the tests, as the clock speed of both CPUís is quite close to one another.
The 17-inch MacBook Pro
saw the greatest benefit from the upgrade to the Sandy Bridge processors with a 53% increase over last years model. This model has very similar specifications to the higher-end 15-inch model. This dramatic increase in system performance may have to do with the AMDís Radeon HD 6750M graphics processor that includes 1GB of dedicated video memory.
Although the latest MacBook Proís didnít include a new case design, which was widely expected, the speed improvements over last yearís models canít be ignored. Using the latest Intel Sandy Bridge processors, the 2011 MacBook Pros are the fastest portable Macs that Apple has ever produced. I canít wait to take one for a test drive.
