Hello,
i was wondering is differenc in speed between I5 and I7 huge in peformanc eor not , i.e for programming not for gamming ?
is that logic to use I7 on 14" instead of I5? yes will be more heat and short life , but the performance will jump extraordinary in this segment ,
thanx in advance

More about : thet worse segment

For programming, you will see 0 difference between i5 and i7 unless you compile huge applications like CPU emulators or work with media files.

+1^
They perform pretty much on par in programming.Unless its a multi-threaded program in which a quad core CPU performs better

thnx for feedback,
I fully agree with all of you, i bleieve no much difference unless multi-thread.
however my other concern , if the visibilty to push I7 on 14" segmen, i thnk it is overloading the laptop. and contradict with the purpose of 14" or less for portability and walk around. what you think

That's true,having a quad core CPU in a 14" laptop will result in overheating,and also shorter battery life(compared to i3/i5)

Depends on the laptop. The manufacturer can compensate with better cooling solutions (more copper) and larger capacity batteries. But again, you get the downside of added weight and increased dimensions. The manu has to figure out what sectors they are trying to target.

Yes but I haven't seen any 14" laptops(with CPUs like i7) without overheating problems.
The best one is Envy 14 which suffers from overheating.
September 21, 2010 9:43:00 PM

i agree wuth Maziar, as the all 14" review for performance was buitl on I5 even with some hear concern on I5, as i believe correct me if i wrong.
the best rates i saw was Envy14, Think T410 and Vostro .however to best suit I7 may be from 15" or higher whihc mena almost station desktop.
the best i saw till now is the Sony Z, whihc combine all the pros.
howver i admit with "lostandwandering "that may be in future more porper solution

I think that HP tried to do too many things with the Envy 14. They tried to make a thin and light laptop, that had beauty and power to match. And you know deep down that they wanted this thing to compete with the Macbook Pros, you can tell by the styling. Personally, I think if they gave up on the thin and light concept and focuses on the looks and performance, they would have been able to get a better cooling solution onto the CPU.

More and more people seem to be interested in laptops that are between 13 and 15''. I have a feeling that we will soon see more 14'' laptops that truly cater to "power" users

I sure hope so,although 15" is currently the most popular laptop, but 14" is also good, if manufactures improve the cooling system, we may see better 14" laptops soon.

I do programming with a core 2 duo and my co-workers use core duo up to i7s

there is almost no difference between them. I prefer the i3s on the laptop since you get the best battery life. I suggest upgrading the RAM
September 22, 2010 8:04:23 PM

thnx for reply,
perfect ,so even using i3 and/or i5 will be more than enough for programming, i.e something like Matlab and V.C++ . so i agree with u to power the RAM and fast hard drive
however is the GPU will have effect ?
a c 244 D Laptop
September 23, 2010 10:35:12 AM

GPU doesn't make a noticeable difference in Matlab,C++ etc.The most important components for those tasks are CPU and RAM
September 23, 2010 12:00:02 PM

So we can summerise the marvelpous brain storm ,

for programming (i,e C++ Matlab ) CPU + RAM no inout from GPU

also, there no much difference between i3 or even I7 for this purpose (even we have feedback the core

2Duo is enough)

fr 14"segment , the presence of i7 , inspite it add more powerful , it will be loading the system form the point of heat and battery time, evenit will depend on manfacture , but thi is a general conculsion .

what you think All, kindly feel free to add coment s
it one of best brin storm

The difference between i3 and i7 is significant, if you want something with a mix of good battery life/performance,look for i5 CPUs
September 24, 2010 12:29:27 PM

i agree with you,

i survey for the proper laptop that match with our discussion and nominate those:-

Dell Vostro 3300 with i5 and dis.graphic, Dell latitude E6410

HP dm4 and HP Elite 8440

Thinkbad T410 i5 + Dis. graphic

Apple Mac Pro 15"

and Sony Z- series and or S series

what you think regarding our discussion for programming applications
a c 244 D Laptop
September 25, 2010 2:35:06 PM

Between those,MBP 15 will give you the most battery life,whereas others(such as HP Elite 8440) have other specs and are cheaper too.
September 27, 2010 6:51:42 PM

sure Maziar,
i really think dm4 and Elite 8840 p is the more decent one specially Elite as it has strong construction
and will be suitable for the programming purpose

what you think

i really think to purchase it with dis, graohic card N Gforce 310M
then seocnd choice Dm4 with dis graphic
then Vostro 3300 +i5+dis card
the lenovo is really higher price as the Mac one
a c 244 D Laptop
September 28, 2010 12:56:33 PM

It depends on you.
Like i said in my last post,HP Elite has the best build quality between them,where as MBP 15 will give you the most battery life.
However if you are going to only work with Windows and leave OS X aside,then go with the HP elite,its not worth it to purchase a Mac and only work in windows with it(because the battery life in windows is significantly lower than OS X)

I'd actually just like to point out that the Vostro 3300 has good build quality. They replaced a lot of the plastics with aluminum. A step in the right direction.
a c 244 D Laptop
September 28, 2010 6:43:25 PM

Oh,thanks for pointing that out.So they finally changed it to aluminum.
I had worked with the older models and it really felt cheap.

Yes, the Vostro V13, 3300, 3400, 3500 and 3700 all have aluminum bodies. I kinda like em.

did u see the performance of Vostro 3300 lostandwandering? any comments beside the battery issue

i like the desigen of Vostro for portability but didnt see it is practise

No problem, let us know if you had other questions.
If money matters,go with the Vostro one, and don't worry.Like i said its a great choice.
October 4, 2010 6:57:35 PM

thnx Maziar ,

i got promotion price for lenovo for 10% beside their saving , on 410T and 410Ts , what you think,
for whatever configuration i can customize, what you think ?
a c 244 D Laptop
October 4, 2010 10:14:24 PM

I think the stock specs is enough for your work.
October 5, 2010 12:39:41 PM


sorry Mazair didnt get ur point ?

a c 244 D Laptop
October 5, 2010 2:56:55 PM

If i understood it right,you are asking about a good customization for Lenovo 410T right? if so then the stock config(core i5,320GB HDD,4GB RAM) suffices, if you meant something else then please clarify.
