Its more expensive! Its more expensive!
Not exactly. The T2330 is almost the same as the T5250 except for a few things. The T2330 has only 1mb of L2 cache(as opposed to 2mb on the T5250), and actually has a higher clock speed at 1.6ghz(the T5250 is 1.5ghz). The T2330 can actually perform a bit faster than the T5250 in certain processes, but for the most part should perform about equal to the T5250. The lack of cache isn't noticeable in everyday usage and only really shows if you have multiple(more than 5) programs open and going at full load, or are running very demanding games. Even then, the difference isn't on a large scale. For comparison's sake, the T5250 has a 667mhz Front Side Bus and a 9x multiplier while the T2330 has a 533mhz FSB and a 12x multiplier. Both have a TDP of 35 watts, are built on 65 nanometer process, and are Merom cores(Merom-2M cores, specifically). They are actually made from the from the same silicon imprint, but after manufacturing are differentiated by either defects in cache or some other problem causing them to not express full capability, which would be a T7250. "Pentium dual core" has become Intel's economy line name, however it's every bit as much a Core 2 Duo as an officially labelled C2D, except for half the cache.
the laptop's info is here, is the problem is from any of them?
