is there much difference between an intel® Pentium® Dual Core Processor ULV SU4100 (1.30GHz, 2MB, 800MHz) and an Intel® Core™ 2 Duo SU7300(1.3GHz,800MHz,3MB)? it's because i'm looking at a new alienware m11x.

how do these processors compare with the i5-520 2.4ghz? from the price quoted it seems these 1.3 ghz processors should be better which i dont understand........

thanks!

The SU7300 will be slightly quicker than the SU4100 due to improved architecture (C2D better than Pentium Dual) and the increased cache (3MB rather than 2MB).

Both would be absolutely smashed by an i5-520 in every measure. Actually, battery life may be slightly better with the slower CPUs, but for anything else, the i5 will be very noticably quicker.

For a quick and dirty comparison of the differences between performance of these three chips, look at the scores that get on PassMark:
SU4100: http://www.cpubenchmark.net/cpu_lookup.php?cpu=Intel+SU4100+%40+1.30GHz
SU7300: http://www.cpubenchmark.net/cpu_lookup.php?cpu=Intel+SU7300+%40+1.30GHz
i5-520: http://www.cpubenchmark.net/cpu_lookup.php?cpu=Intel+Core+i5+M+520+%40+2.40GHz

I know this is only one benchmark and others will show different gaps between them, but the i5 is approx 2.5 times the speed of either other CPU.

Get the i5. :)

wow that's great thanks! any reason then why the su7300 and su4100 are in the NEW alienware m11x which some reviewers reckon is the best gaming machine, ever? seems strange if they're not particularly good processors.

unless hard disk speed and memory are more important for playing games and running other related applications in the background as i am.

should i steer clear of the alienware despite the rave reviews?

thanks once again.........
