i7-720qm+ATI4650 or i5-520m+ATI5650?

I am going pick my new notebook between Dell Studio 1747(i7-720qm+1333MHz ram+ATI 4650) & Dell Studio 1749(i5-520m+1067MHz ram+ATI 5650). The price difference between them is very small in my country.

I will use Intel SSD.
Which one has better performance in gaming?(Cod mw2, Need for Speed World)

Is the power consumption much bigger for 1747(i7-720qm+1333MHz ram+4650)? Or just slightly bigger? If the normal running time for (i5-520m+1067MHz ram+5650) is 1.5hours, what is the approximate running time for 720qm+4650?


Any suggestions or help will be appreciated! Thank you very much.



update:
I just found out HP ENVY 15(i5-520, ATI 5830, 15.6" 1080p) is on sale with a similar price with Dell Studio 1749.

I want a 17” laptop but I can live with 15” as long as the 5830 in HP is much stronger than 5650 in Dell.
How is the gaming performance for HP ENVY 15? Is the 5830 in HP downclocked?

What do you think? I'm really confused right now

 

Both of the GPU come with 1GB ddr3 Memory.

 

I have the i7 720 and 4650 and i can run games on battery for ~45mins. Idle i can get 2h15mins. The difference between 4650 and 5650 is minimal (~1-5%) in gaming. If you are using the laptop purely for gaming then go with the i5 + 5650.

 

Umm, no. The 5650 is actually better than GT330M, which is about equal to a 4670. And the 5650 also consumes less power than the GT330M as well. It's quite an efficient card. Don't underestimate it.

Also, I honestly don't think the i7-720QM will be all that much better for than the 520M. The 520M already has 4 threads, generally enough for most games today. The performance difference between the i7-720QM and the 520M isn't enough to justify the higher price either, in terms of gaming. If running multiple VM's, or doing lots of encoding, then most likely yes.

TL;DR - The 520M and 5650 will generally win, unless it's a heavily CPU dependent game like GTA IV.

What sort of price range are looking in OP? You may want to have a look at the Asus N71JQ. That is quite new, and comes with both the i7-720QM, and the ATI Mobility Radeon HD 5730.

 

The i5 and the 5650 is what i woudl choose.

 

Is the new Need for Speed World a heavily CPU dependent game?

Yes, I know the Asus N71JQ have some very nice spec but it is too expensive for me.
Thank you very much.

 

And i will use SSD in my new laptop, does it affects the different between i5 and i7?

 

I'm not quite sure on this. Is it even out yet?

The SSD will greatly improve loading times. It will not generally affect gaming performance, except for the loading of levels and textures. But an SSD will make your whole system feel a lot snappier and faster, and if you think the price is worth it, you could have an amazing system. An SSD can make a 5 year old laptop feel like a 2 or even one year old laptop.

But generally, for gaming, it won't have too much of an impact. It will just make Windows generally feel a lot faster, and will have a large impact on programs that do a lot of loading from the hard drive.

An SSD that I would wholeheartedly recommend is the Intel X25-M 160GB Generation 2. They come at a price, but they currently have the best performance out there, and the reliability is a lot higher than that of other Indilix based drives. Also, if you have Windows 7, you will have TRIM support, so the performance won't degrade over time, unlike other drives.

 

I would go with the better GPU, that is the 5650 because for most of the gaming it is the GPU what matters (especially laptops where the GPUs overall mediocre when compared to desktop counterparts).

Have you considered the Asus N61 series? If in US you can get the i7-720qm with the mobility 5730, which is way better than the 5650 for an affordable price.

 

The beta version of new NFS is out, but i haven't tried it yet.

Yes! All of my friends told me to try the Intel one, I think I am going to get a Intel X25-M 80GB. With a 500GB second hdd for storage, i think it is more than enough.
What is the different between gen1 and gen2? How can i separate them when purchase?

 

I know N61JQ is a nice laptop with an affordable price. But the problem for me is it only come with a 1366x768 screen. I need to Photoshop and a high resolution display would make things so much easier. And I want to use SSD in it. N61JQ only able to use 1 hdd which mean I need to get a much expensive 160GB version for storage.

Thank you very much for your suggestion!

 

They should say the different generations when purchasing, if it's a good store.

And Generation 2 has TRIM support, and Generation 1 doesn't.

 

better gpu for sure, not all applications have use 8 threads anyway. and the i5 will run cooler too. the cpu will not be a bottleneck, the i5 is already quite a strong processor

 

I think the i5 with ATI 5650 would be a better overall choice due to the stronger gpu (which is usually more important in games), and the cpu should really not be a bottleneck either.
Even in games such as GTA IV because the i5 series cpu is still better clock per clock in contrast to the Core2Duo series, plus it comes with 4 threads (which admittedly is not the same as having 4 cores, but relatively close ... as far as games are concerned).

 

the i5 and 5650 would be better for gaming but i would look at other options in 17inch which are no that much more expensive but have better GPU.. u can get a Asus G73 for $1499 with 17 inch full HD screen and 5870 which would own any game... another option would be Sager NP8760 which would be more expensive.. for ur uses , G73 might be great... and as for SSD , get Intel G2 version.. Has TRIM and should last longer be faster than G1..

 

I just found out i7 one is using 1333MHz ram and 1067MHz for i5, does the 1333MHz ram improve the gaming performance?

 

No.
Ram speeds do not carry an impact on games or offer any noticeable performance difference during general functions

 

if u play games, 3D ones, definitely the 2nd combo.
i7 maybe faster than i5 in day to day application but speed is not crucial in those application like web surfing/programming/video processing. but for game, if it's not fluent, u cant enjoy.

 

He already said he can't afford something that powerful. If he can't get an N71JQ, then I doubt that he will be able to afford the G73. It may not even be available where he is anyway, it isn't in any retail outlets here. The only way you can get one here is to buy it from the Clevo reseller.

 

well the dell isn't cheap anyways and isn't a best buy G73 $1299? I don't know.. the studio 17 might be cheaper...

 

thank you for your suggestion. but in my country g73(1080p) cost around ~1700USD, g73(900p)~1450USD, dell studio 17 ~1150USD. therefore i am not going to consider about g73.
thanks again.

 

I have the i5 520M and the Ati 5650 in my laptop and it handles anything that I through its way.

 

go for the i5+ati5650. this is because gpu is the main bottleneck in most games. also the 5650 will run cooler than the 4670 as it's made in 40nm. this will also result in lower power draw and hence increase in battery life.

 

ok sorry , thought u lived in US... Well here in UK , full HD version is 2800USD so count urself lucky ... just joking but i5+5650 is still quite sick but not good enough for full HD.. quite good for 1600X900..

 

What? That's crazy. It's even cheaper than that where I live, and usually technology here costs twice as much as the US.

 

if it is for gaming, then i5 + 5650 should be your choice.

efficient, and more powerful in today's games. Not to forget DX 11 support

 

I just found out HP ENVY 15(i5-520, ATI 5830, 15.6" 1080p) is on sale with a similar price with Dell Studio 1749.

How is the gaming performance for HP ENVY 15? Is the 5830 in HP downclocked?

What do you think? I'm really confused right now

 

I don't think the 5830 in the Envy 15 is downclocked. And the 5830 is a fair bit stronger than the 5650. Take a look at the following link:

http://www.notebookcheck.net/Comparison-of-Graphic-Cards.130.0.html

The 5830 is lower class 1, and the 5650 is middle - high class 2. The difference isn't too much, but I'd say it's worth it.

It's really up to you whether you want a 17" or 15" laptop.

 

HD5830 is not downlocked in HP but it is lower clocked compared to HD5850- that's all.
There is one thing I would seriously consider looking at 3D Mark scores for HD5830- it's not meant for gaming in 1080p.
In 3DMark06 1280x1024 it scored 8000 which is not that much compared to 5650. It may be faster per se but it will be slower when you take the resolution into account. I wouldn’t wanna play games in non-native resolution- it looks hideous IMO.

 

the envy is better than the dell but not really for gaming on full HD with max settings.. it will do full hd but with med-high settings but if ur getting it for the same price , grab it!

 

QFT. Older games it can play at full details at 1080p. C&C3:KW I can max things out and it never drops below 30fps. L4D2, it can hold 60FPS in most situations without AA at 1080p. Now, you start looking at new DX11 games, you may have to drop below 1080p resolutions. That said, you will be able to max out almost all games at 1280x720, and it still looks beautiful (IMHO).

 

its really hard to choose between better gaming details and a bigger screen!!

 

better details... bigger screen doesn't help much.. i went from 17inch monitor to 15 inch and had no problems but the better details help.. envy is my choice
