Reasons to buy the 3230M

	Significantly higher clock speed 2.6 GHz		Higher turbo clock speed 3.2 GHz
	Significantly higher GPU clock speed 650 MHz		Better PassMark (Single core) score 1,583

A comparison between the Intel Core i5 3337U and the Intel core i5 3230M is a tricky one to make because the two processors are similar, but have several things that differentiate them from one another. First thing is the processing power: while both processors sport two cores with hyperthreading, four threads and 3MB of L3 cache, the 3230M beats the 3337U in the raw processing power category. The 3230M is clocked at 2.6GHz (3.2GHz with Turbo Boost) whereas the 3337U is clocked at 1.8GHz (2.7GHZ with Turbo Boost), clearly showing that the 3230M is the choice for people who want a CPU with more raw speed.
In the graphics department the 3230M also outperforms the 3337U in terms of speed: 650MHz for the 3230M and 350MHz for the 3337U. However it’s important to note that both share an identical Turbo speed of 1100MHz. Though, in the end, the 3337U has only a few things that it does better than the 3230M: it consumes less power (17W versus the 35W of the 3230M), as the table below shows, and is therefore more suited for smaller, less power-hungry machines.
I've done my best to provide a clear comparison between the two when testing them, but as the statistics below show, one is just marginally better than the other.

and also between the 3 i would say HP's got a very good build quality compared to Dell and Lenovo Personal opinion go for HP they also support International Warranty like the rest but worth it

Suraj S (11:05 AM, October 11, 2013)

i see that looking in GITEX Shopper Anyways to the Point the Dell would be cheaper if u look around but when it comes ti processing speed the HP and Lenovo will outlive it Its got a way better processing speeeed even after turbo boost and also significant reduction in battery consumption which lot of us look into. So between the HP and the Lenovo go for whichever Design is better and also note the Lenovo's are bloated(lot of factory installed softwares) Also check of for both if they have graphic cards probably you wont have in the given price range
