Welcome to IPIP. I always emphasize that this portal is to share new ideas or discuss issues encountered with Intel products or solutions over Intel products and even on other OEM products to get a resolution while we always discourage the attitude of THIS OR THAT'S BETTER. That is because performance benchmarks are done by experts and posted all across the internet for users and experts to see, then it's one's own prerogative to go for whatever s/he choose. However here are a few links that you might find useful, otherwise you can always Google processor performance benchmarks.
