which is better for gta iv??i7 720qm or i7 620m?(or is i7 820qm compulsory??)

hi.......im interested in one of these three gaming laptops msi gx740,acer 8942g, asus g73jh-x1...........both have the same processor (i7 720qm)..asus and msi have ati 5870 while acer has ati 5850.....both gpu dont have much difference in performance...anyways....problem for me now is that all of them have i7 720qm which is though a quad but has a lower clock speed which is 1.6hz while i7 620m (not included in above laptops) has higher clock speed but is a duo..so which processor would be good for gta iv????and other modern games like splinter cell conviction,crysis,geras of war????????if quad is better than how much difference in perfomance is between i7 820qm(1.7 ghz) .......plzzzzzzz help!!!!!!!!

 

Gaming wise there isn't much of a difference between the i7 620 and 720. They also cost about the same and simply perform similar with the 620m winning in some areas due to the higher clockspeed but nothing earth shattering.

Go with whichever you like. I'd say that between those particular choices, go with the cheaper one.

 

The 620m is a dual core but it has HT so it can process 4 threads like a quad core. In gta4 the 720qm will perform slightly better because it has 4 actual cores and HT (8 virtual cores). BUT gta4 and a few other cpu intensive games are the exception.
With 90% of games the 620m will perform as well as or better than the 720qm and both will perform well in all modern games. The 820qm is unneccesary because it's not that much a leap over the 720qm and the 620m and it's a far cry from the 920xm.
Hope that helps

 

My laptop has a Q720m and GTA 4 and EFLS play smooth even when theirs lots going on.

 

Also the thing never runs at 1.6ghz. Its between ~920mhz and ~2.8ghz

 

If you want to play GTA IV, you will need the Quad, otherwise go with the Dual. I tested GTA IV on the i7 620M Dual Core and performance was terrible with lots of stuttering and even lowering all settings didn't make much difference. GTA IV uses almost 100% of all 4 Cores so you can understand why a Dual can't keep up under normal circumstances.

 

ok i get it that i7 720qm is the most suitable one to play ta iv smoothly and without lags..........but what about games which require dual core.......like splinter cell conviction,prototype,assassin creed II.............who do these games perform on i7 720qm????

 

It'll perform fine. When we say that the dual will perform better in most games its by a very small amount as most games today are gpu bound. So as long as you get a decent gpu you'll be fine with any i7.

 

GTA IV will run better with the i7 720QM based on my experience.

 

Take the i7 720QM.

There's zero logic in taking a dual core CPU for gaming these days.

 

To me, the main factor comes down to the cost of each CPU upgrade.

 

Btw...

- the Acer's 5850 is GDDR3, so, the performance difference to a 5870 will be huge.

- Forget the 820QM. It's the biggest rip of them all.

- If you go dual core, save yourself some money, and take a Core i5. The 620M isn't even a worthy improvement over the 540M. Total waste of money.

 

Dude be aware i m 110% sure acer comes with gddr3 5850 .Plz dont go with dat,coz that memory will literally halt the performance of otherwise gr8 card.
To ya question.Yes gta 4 will surely benefit with a quad core.I don think u need to go for 1.73 ghz one.U wont notice much difference bw 720qm and 820qm than u will notice from i7 620m to i7 720qm(dual to quad core)

 

Haven't played GTA IV till now, but you must have got a pretty good idea about how i7-720QM performs,from others' post. Regarding other games like SC:Conviction, COD MW-II etc.., as mentioned it is more GPU-bound,(even with ATI 5730 MR, I can manage 30 fps or above @1366x768. So , with 5870 MR, it will run just fine)...

 

very true.. but even on my T9400 , games play well.. maybe not on higher details at full HD res but at 1280X800.. but really quads will be better..

and Yes , 5000 posts

 

Keep in mind that the games are more CPU-bound a t lower resolutions;as you go higher in resolution, generally the effect a CPU would have decreases. (which is why, most sites which review CPU's include testing games at lower resolutions,even though I suppose the number of people who buy a decent graphics card is unlikely to game at such lower resolutions....)

In short, if price,extra heat/power is of no issue, then go for a fast quad core...(or else if you run many applications which are heavily threaded; or need good performance in a few which are so, then go for a quad core).

Right now, quad core for Dekstop PC's(say, if your budget is >200$) make more sense, than going for a quad core for laptops as the greater power consumption/heat(thus lower battery life) would be a bigger issue for most laptop users.

 

Wait am I understanding this correctly? Its actually better to play games at higher resolution if you have descent hardware? I Bought my Alienware (sig) with a 900p thinking it would be easier on the hardware and I'd get a longer life out of it. Was I wrong in this assumetion?

 

I consider anything from 1600 x 900 and upwards to be high resolution. It is better to play games at native and you are correct in thinking the 900p will be easier on the hardware and it will give you a longer gaming life at native. The 900p is very respectable but many still prefer Full HD for various reasons for example more screen real estate or Blu-ray movies.

I went with the 900p for the same reasons as you did and benchmarks show anywhere from 10 fps extra at 900p Vs Full HD in gaming and it still looks great. Many will argue that you can just buy a FullHD screen and then just lower the resolution but no matter how high the screen quality is or how you set the aspect ratio, you always lose quality and get lack of definition and blur.
