it have 2 cores but simulate more 2
Go with 3230M ..... its more powerful but be sure to plug in your charger while gaming or using softwares ..... ps the 4200U has hd graphics 4400 and 3230M has hd 4000 .... the differences are only 2-4 fps but with a proccesor like those two your human eyes wont even notice so go ahead and buy 3230M .....
i have an intel atom
the dxdiag on my computer tells me that the i5 3230M has 4 cores !? kinda weird...
which is better i5 - 4200u (4th gen) or the i5- 3230M (3rd gen) ? i hear that 3230 has better clock speed but 4200 has lesser power consumption and a bit more features . I'am confused as i want to buy a laptop that fits for gaming as well as software development ... please help !
i have a asus laptop with the 3230m and it's pretty solid performance wise but the battery life is not great
Sorry not much faster but equally fast in everyday performance
As the description explained the 4200U is for ultraportables and is 15W tdp, the battery life will be much better on the 4200U but the 4th gen will be much faster for most everyday users while the 3230M will be more powerful for those obsessed with benchmarks...The 3230M is a great CPU - there is no reason to upgrade from the 3230M but both are equally fast as computers and cpus have hit a "plateau" a while back where each new generation on the similar TDP suffix is only 5-10% better than the last generation. P.S. I am typing this on a 4200U powered computer and its amazingly fast!
I have the 3230, it can perform better than written, and have never reached 80^c, also very high speed reading and writing in ram with only 1 channel used with a 4gb 1600 DDR3 ram, 14000 mb writing and 17000 mb reading on AID 64.
Error in main intro text - 4200U is 15W not 35W.
its bullshit the processor 4200u is 4th generation and the other 3230m is 3rd generation there is no compare of them.
