APrimate Labs launched this morning its overall performance analysis of the new MacBooks Pro, released this week with the latest Intel processors and higher graphics performance. The tests were done with Mac OS X 10.6.3 and Geekbench 2.1.5, on machines with 4GB of RAM.
One of the points at which Primate Labs was most impressed with the new notebooks is the fact that the performance leap between the Core 2 Duo processor and the new Core i5 and i7 is enormous, even more so given that they have an operating frequency much smaller than the ancestor. When comparing the 2.4GHz Core 2 Duo (the fastest in the 13-inch line) with the 2.4GHz Core i5 (the slowest in the 15-inch line), the tests gave an advantage of more than 30% for the latter, in general performance.
This is interesting because Intel's advances in microprocessing are allowing today's notebooks to have greater performance gains while consuming even less power than before, and this is decisive for this category of computers. These gains have been obtained thanks to the improvement of other internal functions of these chips, instead of just the concern of increasing the number of internal transistors.
With so many configurations available between the Core i5 and i7 processors, Primate Labs received several questions about which one would be the best to consider on a MacBook Pro the 13 inch models with the Core 2 Duo would even be interesting, if they were not already in demand too high. For the specialist in benchmarksIf the users need not involve using a screen of the highest resolution available, it is advisable to invest in a 15 inch machine with the latest Core i5 processor, using the money from the Core i7 to increase the RAM to 8GB.
Two days ago, Gizmodo also published benchmarks preliminary results of the new MBPs, bringing results that are not very different from the ones we just saw.
