Intel's latest Sandy Bridge based processors helped the new Apple MacBook Pro family outclass their predecessors by as as much as 53 per cent according to a benchmark test published by Macworld.

Macworld, which publishes its own proprietary benchmarking test, showed that the new quad-core 15-inch MBP is 50 per cent faster than the entry level 13-inch MBP which is a dual core model.

It is also interesting to note that while the jump from the 2.3GHz Core i5 to the 2.7Ghz Core i5 is not linear (i.e. an increase in clock speed doesn't generate a comparable increase in score), the opposite was true for the quad core processors, going from 2Ghz to 2.2Ghz.

The new 13-inch MBP was just over a third faster than the model released last year but fatally proved to be a poor gaming platform as the integrated Intel HD Graphics 3000 video module failed to keep up with last year's Nvidia graphics card.

It was the 17-inch model however which appears to have gained the most in terms of performance. The 2.2Ghz Quad-core model was a whopping 53 per cent faster than its predecessor thanks partly to its new AMD Radeon HD 6750M graphics card with 1GB dedicated memory which makes it better at games.

Macworld also tested the new MBPs against the existing Apple iMac all in one desktop line and found out that the laptops were quite competitive (and even faster) when compared to their desktop counterparts.
