I5-520 versus i7-720 for single-threaded application

Hello,
I'd like to know which processor, the i7-720 or the i5-520, will run what I assume is a single-threaded program faster. The program creates a crossword puzzle, beginning in one corner of the crossword and working its way across, finding all the words, or word combinations, that fit together. It's time-consuming but not really very complicated, and in fact my desktop with an ancient Pentium usually runs the program just fine (although it does take a while), but I was wondering which chip would run it faster (assuming the same RAM and drive speed in the competing setups.) I do not run any other programs at the same time.

Choice 1
Core i5-520M (2.40GHz, 4Threads, turbo boost up to 2.93Ghz, 3M cache).
Choice 2
Core i7-720QM Quad Core Processor 1.6GHz (2.8GHz Turbo Mode, 6MB Cache).

The I5 with its 2.9ghz turbo mode will be the faster one for single threaded apps.

Thanks, Saiello. I'm not technically inclined but that's what I was thinking. (Funny that the "lesser" processor is actually the better choice.)

well the 720 will have the upper hand in multi threaded apps hands down. But the difference would be barely noticable in single threaded apps.

Important point! I mean "better" only for this one, absurdly noncritical application (and even then faster by a degree that although technically small looms large to the user ego).
