I am thinking of buying a dell studio 15 laptop. But confused about the processor to buy. I am confused between Core i7-720QM and Core i5-540M. There is a price difference of 7K on the Dell India site.
I am an average computer user. I am not into heavy multimedia stuff. But i am an avid gamer though not hardcore. I need to be able to play the latest games that are coming up. Apart from that watching movies and surfing the net is all what i am going to do.
So what difference the following features will make?
i7-720 vs i5-540
1. 4 cores(8 by HT) vs 2 cores(4 by HT)
2. 8MB vs 3MB of Intel Smart Cache
3. 2.5 GT/s vs 4.8 GT/s of DMI
4. 45nm vs 32nm processor die
5. Integrated graphics of i5. i7 does not have any i guess.
I am also getting a 512 MB ATI Radeon graphic card, 4GB DDR3 ram and 500gb HDD.
Is it worth to put the extra 7K and go for i7? I might benefit in the near future. Or will the i5 be enough for my needs?
^ For gaming, even that i5 would suffice...The laptop has low resolution and both the laptops use the same graphics card - 4570...So I dont think you would notice much difference in gaming between these CPUs as both have enough power to support that graphics card...but in other CPU intensive tasks like video converting, and such stuff, there will be a significant difference...
The way I see it an i7 should be better for quad core applications, like video encoding but probably about the same/slightly worse at dual core applications. Switching to integrated graphics on the i5 would give more battery than the default ATI GPU so could prove better.
Well I have an i7 720Qm and looked at a very similar Dell spec. and borked at the price, then I got an HP DV7-3020ea for £890 with better specs.
Remember integrated graphics steals main memory, thus Windows has less to play with reducing performance and as your a gamer, it will ruin your gaming experience.
Beg, borrow or steal and get a i7.
Cool. Did you encounter any heating issues? What about battery life? I was planning to go for a 6-cell lithium ion battery but after reading the reviews i guess a 9-cell battery would be perfect. what do you think?
I am for a i7 but a differnt dell system a alienware M17x. But with dual ati 4870.
Most games work great on low end cpu. What really needed is gpu power. Last two laptops was a alienware m5550 core 2 2.33ghz and m17x core 2 2.4ghz. And games ran good. Just due to the issue of the laptops I had to send them back.
Setup now is M17x i7 720 with dual ati 4870 and 8gb of ram and 1.2tb of hard drive space.
You are comparing an old i7 with the best i5 model to date. I say (as with the desktop i7 750) the i5 is the winner for gaming. How can you compare an i7 that with two cores has 2.28 GHz vs a 2.53 GHz fast i5. If you want a fair fight put the 5240M vs a 620M or 820QM...
Hey i got a similar problem too. I have to choose between an i5-540m vs i7-720QM.
The thing is if i go for the i5 i can get 6gb DDR3 else a 4gb DDR3.
The gfx i am getting is the 5470.
Suggestions Please ? I have too book in a day or two.
Thanks in advance.
