I am very perplexed over these two choices.
What would be the merits and demerits of buying a laptop with
>>intel i5 4200M ( @ 2.5Ghz- turboclock speed of 3.1Ghz / integrated GPU of intel HD 4600 @ 400Mhz) and GPU of Nvidia Geforce 820M ( working at 775 Mhz)

>>intel i5 4200U (@ 1.7Ghz-turboclock speed of 2.6 Ghz / integrated GPU intel HD 4400 @ 200 Mhz) and GPU of Nvidia Geforce GT 720M (working at 625 Mhz)

Can anyone guide me how different are they from each other? Am i be able to play less number of games on one laptop than the other?
Will there be lots of lag ? How exactly does the clock frequency matters ?

He won't be getting that much more. I have a laptop with a GT 620M, Nvidia still uses the same chip inside of the GT 720M and 820M with the same memory interface as they did with the GT 620M. Anyways I overclocked mine from 625Mhz to 865Mhz, and I went from a dual-core Core i5-3210M running a max of 2.8Ghz with all cores in use, to a quad-core Core i7-3632QM running 2.9Ghz with all cores active. After doing this, I got an...

the 1st one because the processor and the gpu have higher core frequency than the 2nd one. - higher frequency is equals to faster calculations and processing of data.

you'll be getting 10-20 more fps on the 1st build - that is 3.1 ghz against 2.6 ghz on the processor and 775 mhz against 625 mhz on the gpu.

The Top choice would be the better option because the I5 4200u is the power saving version basically of the I5 4200m which is slower to save more power and the nvidia 820m is just a tiny bit faster than the 720 The difference in games however would be minimal because they are so close. If the I5 4200u version is a lot cheaper I would just go with it. I hope i helped.

After doing this, I got an improvement, but it was closer to 8FPS faster at best.

Given the much smaller jump between those two, 10-20FPS is overly optimistic but likely it will get maybe 4 or 5FPS faster performance.

That was very helpful! So do they stand equal or there is a winner? [/quotemsg]
They are very close if there is something like a 50 dollar difference I would just go with the 820m but if there is more of a difference than just go with the 720m laptop.

My apologize for the ambiguity, the system with the i5-4200M and the Nvidia Geforce 820M is the better system. It is certainly the one you want, it is better than the other one. Its just not quite as much better as what he was stating. Still a good improvement though.

I am getting both at equal price, so its 4200M +820M the best choice! Thanks.

yeah i was thinking the same while i posted that it just i could not edit it earlier. i stand corrected and 5-10 fps depending on the game if it is cpu or gpu intensive - would be the difference between the 2.

May i know whats the best substitute for same configuration in AMD series ? How about A10-5570M ?

No worries, if I didn't own a system with one of these inside of it and had the first hand experience from it, I probably would of thought the performance difference would of been bigger too. 150Mhz is a pretty big clock difference on the GPU, just the limited 96 CUDA cores gives a lower performance bump from clock speed increase than the bigger models.

Still an impressive difference though :)

P.S. Not sure what kind of battery that laptop has, but if it has a good battery you can actually do some good gaming with this on the go. It only has a 15w TDP. I have a 7800mAH battery and can game for about 2:30 hours with the GPU maxed out usually before the battery dies. These small GPUs lack the performance of the more expensive laptops with larger GPUs, but they have a lower power consumption that really comes in handy for mobile gaming.

Do you mean the A10-5750M?

If that is the case the CPU is kind of close to the i5-4200U, but it uses more power. It does perform better in games though, it would have a faster GPU than the 820M. In addition the CPU and GPU in a laptop with an A10-5750M would probably consume roughly the same amount of power as the laptop you posed earlier with the i5-4200U and the 720M over all. The A10-5750M with it's GPU only have a 35w TDP, while the i5-4200U has a 17w TDP, and the GPU has a 15w TDP, together is 32w TDP for the system. So not a huge difference in gaming power consumption.
