[vampelle]

hi, i would like to know what is the differences in the processors with "m or u" with i3 or i5.

as i am planning to buy first time , i would like to know what the advantage of buying m or u and which processor is good enough to do everything and gaming too.

later i would like help in buying too. budget is $500-650 (Rs. 50000-65000). ultrabook, refurbished one or intel warranty one(which does not cover in my country) as buying local warranty dont give me windows preinstall.

some of the example of laptop with website with u and m and i3 and i5.

An ultrabook will have a U processor, which is similar to an M processor, but with less power. The U means it has a TDP of under 15w, if I'm not mistaken, while an M can have much higher. Less power means less heat and longer battery life, but also a slower computer, and will most likely not perform well in games. The Acer Aspire is probably your best choice out of all of those, as it is not an ultrabook and will give you better performance.
