Single core I7 or dual or quad core I5?

Posted 01 September 2012 - 10:06 PM

Hello, I am looking to purchase a new laptop within the next 2-3 weeks. It will be used primarily for coding/web design, on-line school, social media, office products, etc. I have had my heart set on getting an I7 for awhile. Unfortunately, my budget has dropped and I now need to try to find something under $700. Specifically, I had decided awhile back I wanted a quad core I7, but that appears to be out of my budget. I am wondering if I'd be better off with a machine that has a single core I7 or one that has a dual or quad core I5? I don't know which is a better jump in processing speed, from the I5 to the I7 or from a single core to a dual or quad core? I am really hoping to get a 3rd generation.

I'd appreciate any insight.

Thanks,
Shane

Well, a single core is one CPU, a quad core is basically 4 CPUs on one die. Multi core is able to multi task better.

And the multi-tasking is one of the main reasons I need a new machine so I can bounce back and forth between different programs without tapping my fingers waiting.

So would you say this is a correct summarization:

I7 > I5 for single program processing speed

but

dual core I5 > single core I7 for running multiple programs simultaneously?

I typically run at least Visual Studio, Internet Explorer (with several tabs), Outlook, Teamviewer, and iTunes. Oftentimes there's more. This is why I started second guessing my need for the I7 and am now considering a multi-core processor.

Do you mean 1.7GHz single core / 1.5GHz quad core ?

I side with Gunnerinc, if those are both the same price then I would go with the quad core CPU.

I found a few possibilities last night, here are 2 I'm strongly considering:

Acer:
Intel Core_i5_3317U Processor 2.6GHz (3MB Cache) - Dual Core
6 GB SDRAM RAM
500GB 5400rpm Hard Drive
15.6-Inch Screen, Intel HD Graphics
Windows 7 Home Premium 64-bit

Asus:
Intel Core i7 3610QM 2.3 GHz - Single Core
4 GB SO-DIMM
500 GB 5400 rpm Hard Drive
15.6-Inch Screen, Intel GMA HD
Windows 7 Home Premium 64-bit

I'm leaning towards the Acer since it's a dual core and 2.6GHz vs 2.3 and 6GB RAM vs 4. (And less $)

I would go with the Acer too. The differences are pretty big between those two.

There is no such thing as a single core i7. i5s are dual core, but each core is dual threaded like the i7.

That means that the i7 has 8 threads (on 4 cores), and the i5 has 4 threads (on 2 cores). No idea why the specs say otherwise, but they're definitely incorrect. An i7 would never be single core, or less powered than an i5 (unless you was pitting the highest end i5 against the lowest end i7).

Check out the specs for the i7 here and the i5 here.

I would go with the Asus and upgrade the RAM on it where possible, as was mentioned before, the differences are significant, but for all the wrong reasons. Acer are a terrible hardware manufacturer for one :)

A thing you should also remember is that all of the Intel i* procs have turboboost, the i5 would only go to 2.6GHz from 1.7GHz base, and the i7 would go all the way up to 3.3Ghz from 2.3Ghz. There is simply no competition between the two, if you're going to use the power.

RudiVisser, thank you for that info and the link to Intel's specs. I appreciate that. It looks like there is quite a big difference and that I should keep focusing on an i7 s long as I can afford it.

Future Pro: If want to compare the computing power, it's best to look at various benchmarks for the two CPUs.

PassMark
CPU World
Anandtech Bench

There are a few other factors in Computer Systems that can ultimately make for a more powerful system, but CPU power is the most influential.

Amazon. I added the "Single Core" and "Dual Core" lines because I thought that's what they were, but the rest of the specs were copied and pasted.

Sweet, I'll check those out!

Yes, it seems to be competitive and I had a few friends refer it as well. tbh I am hoping to find the right laptop on Amazon as I have a couple hundred dollars in gift cards there to put towards the purchase.
