Intel i5 or i7 chip...huge difference?
Posted by The Pirate King on 11/25/14 at 10:59 am00
Basically I'm getting a laptop and the model with i5 is 80 dollars cheaper. The laptop will basically only be used for minor word processing and Internet surfing and possibly Netflix. should I spring for the i7 chip?

Depends the chip.
Some high grade i5s can out perform low grade i7s.
Do you have specifics on what chips you are looking at?

Intel i7 dual core 2.8 GHz 640M
Intel i5 dual core 2.67 GHz 560M
Intel i5 dual core 2.67 GHz 560M

I could be wrong, but I believe the primary difference is that the i7 enables hyperthreading. If what you plan to use the PC for is not made better with hyperthreading, then the i5 would be more than sufficient.

As kingbob said, the primary difference is hyperthreading. Both chips have the same single core performance, which will be most important for the basic stuff you said you'll be doing. The hyperthreading would likely never be used.

That's a pretty light work load. Do you need this laptop to be portable, in which case which chip is better for battery life?

Both have the same TDP and same 32nm lithography.

Then it sounds like he should follow the "get the most power you can afford" rule.

Battery life would be a plus. I'm leaning towards the i5 due to the fact that I have a light load for it. The computer is a Dell E6510 pro

Not if the power will never be used. This isn't even a matter of future-proofing either. Both of the chips he named are over 4 years old.

What's the newest next big thing in the chip department?

I wouldn't necessarily chase after the latest and greatest for a browser/netflix/office laptop. But in general, CPUs get faster, lithography smaller, and they use less power. Integrated GPU gets improved incrementally as well, depending on the model.
The popular i5 being used in modern laptops is the 4200U. Compared to the i5-560M, the 4200U uses less than half the power, is 25% faster overall, and about 10-15% faster in single-threaded applications.
I also want to add that I was wrong regarding the i5 and i7 differences in the two chips you mentioned. Both of them use hyperthreading. The differences are that the i7-640M has a slightly higher clock and turbo speed and more L3 cache per core. Both CPUs are dual-core with hyperthreading. I still don't think you need the i7, but if the price difference is small (less than $30 or so), it might be a reasonable upgrade, though you still probably won't take much advantage of the extra overhead.

I need to stop opening threads and responding in them 11 hours later without refreshing first.
Overview of all Intel Core series and what it means:
i3- never hyper threaded. It is always dual core.
i5- always quad-thread, regardless of number of cores (dual core are HT, quad core are not)
i7- always hyperthreaded, regardless of number of cores (2x threads than cores, always. Can be dual, quad, or hex (non mobile) cores)
In this case, as pointed out, you've got two dual-core, 4-thread cpu at 2.66 and 2.8 GHz. Overall performance in any setting is better very marginally in the i7. Is it $80 better? Well, it's tough to say what exactly $80 is. But put another way, if you put the $80 into a 120gb SSD and drop it into the i5, it will be a noticeably faster machine than the i7 at the same price (several SSd options come in under $80, so for even less than the price of the i7, you could get better performance (with a teeny bit of getting your hands dirty) for less money than the i7).
Even without upgrading to an SSd yourself, I'd save the $80.
ETA- damn it again. I replied to myself instead of editing. I feel like a douche. And I'm wrong.

Not to be a dick, but I gotta correct this. All i3's do have hyperthreading. They lack turbo boost.

Eff me, I'm bad at this. I3 are locked at two cores and HT'd, you're right.
