Core2 Quad vs. i7 Duo core for computationally intensive tasks

Last response: in CPUs

Hello. I have a HP desktop PC (Intel Core2 Quad Q9400 @ 2.66Hz, DDR 2 4GB, Vista 64-bit) and a MacBook Pro 2010 (i7 2.66GHz Duo core, 8GB DDR3). The MacBook Pro has both Vista 64-bit and Mac OS/X installed. For running computationally intensive programs such as Matlab/Simulink, which platform gives the best performance in speed? If I upgrade the RAM on my HP desktop PC to 8GB, will it be faster than the MacBook Pro because the CPU is Quad core? I read that "a few routines" in Matlab/Simulink support multi-cores CPU. However, the i7 has some kind of turbo boost feature. Thanks.

Hello and welcome to the forums :) 
Well although the MBP has an i7,its a dual core CPU(i7 620M).So your desktop would be still faster in tasks that benefit from multi-core CPUs

A C2Q processor vs. a hyper-threaded dual core processor with a better architecture and DDR3 RAM running at the same speed?

I'm inclined to think that the i7 would have a same advantage. You could always benchmark both systems and let us know.

Thanks for the replies. Actually, what is the simplest and best way to do the benchmark?

There are some apps like 3Dmark,PCmark which benchmark the system, but i recommend testing with real-tests such as PhothoShop,3D rendering... to judge their speed and performance
