So I've been following this forum very closely ever since the new air came out, and I'm surprised that I haven't seen a satisfying comparison between the core i5 vs i7 for 13 inch air.
I was relying on cnet but they don't seem to have both products to make a comparison.

So how much better is i7 compared to i5 for:
game?
garageband?
imovie?
handbrake?
etc...

Is it worth the price?

Well I can only tell you an overall of what I have read around the net, but it won't make any difference in games except maybe in load times, be about a 10-15% increase in your other programs, and that it may cause more heat/fan noise then the i5. Although that last one is still being disputed.

If its worth that then its up to you.

Yeah, I really don't think there is that much difference. The i7 is slightly faster, and runs slightly hotter (which means fans may come on sooner and spin a little faster). But I really think people are making a bit too much of the difference. If you gave 100 people a random model, I wonder how many people could tell by using them without knowing.

Honestly, I have taken this approach, its a $90 upgrade to get the top of the line processor. If $90 is something that bothers you to spend when purchasing a new mac, you might want to reconsider buying a mac at all. Now the price difference between the 128gb and 256gb SSD might be something to ponder as its a $300 swag, but $90...That's a no-brainer to me..Especially since it will also help with the resale value if you ever want to upgrade next year or the year after that.

As far as heat between the i5 and i7, there is no difference I can tell. I was in the apple store tonight before I bought my MBA i7 13" and I spent about 45 mins to an hour cranking on their display models(Itunes video encoding, etc) and I could tell no difference on heat. The store specialist even helped me load stuff on the Mac to pound on it and I just could not tell the difference heat wise. We loaded iStat on both models while we loaded stuff up and it was pretty even temp wise no matter what we did.
At any rate, I hope you find the model that is right for you!

I really don't need 256gb. I can get a cheaper and larger hard drive for my need.
so i'm basically paying $400 more for i7 and after reading, I can't justify the price :( (as much as I want the ulimate)

Can you guys find a link that compares the two?

If you don't need the HDD space of the 256gb SSD, then the 13" i5 128GB will certainly do the trick.
Like I said before, the price of that SSD would worry me more than the price of the processor upgrade. Sadly I don't think you can get the processor upgrade without the SSD upgrade.

Are you set on the 13"? You can get the Core i7 in the 11" model with a 128GB SSD, though unfortunately, on the 13" you need to get the 256GB SSD. It seems Apple didn't want to have a 10th model MacBook Air (or they figured that buyers would just go for the more expensive model).

That said, on the 13", there is much less difference between the i5 and i7. Both support all the virtualization features (for whatever that's worth), and the difference in Turbo Boost is much smaller between the 1.7GHz i5 and 1.8GHz i7 than it is between the 1.6GHz i5 and 1.7GHz i7. The i5 in the 11" boosts only to 2.3GHz while the i5 in the 13" boosts to 2.7GHz. The i7 boosts to 2.9 GHz.

Overall the i7 is much speedier than the i5. Programs load faster and renders faster. I'm satisfied with mine. I keep trying to find an excuse to exchange it, but this thing won't let me. It says cool and silent. Fan is living at 2k rpm. Heat does go up depending on the task. But that goes for all cpu. If you want the best, then its the i7. If you can do with being second best, get the i5 and save yourself a little money. Each person has to make the decision the extra money is worth it. I did because I can get a 13" i5 for 1550 vs. a 13" i7 for 1630. For $80 I'd rather know I have the fastest out there. People may say it's not worth it. But until you have both machines in your possession, it's tough to make that choice. Believe me the i7 is the faster of the two. Heat they are on the same level as the i5. Give or take a degree. Hope you make the decision that's best for you and your wallet.

An i7 in the 11" speed wise is a much bigger improvement over the i5 in that model than the difference in the 13".

1.6 (2.3 turbo) v 1.8 (2.9) turbo = 600mhz turbo single thread boost on 11"
1.7 (2.7 turbo) v 1.8 (2.9) turbo = 200mhz turbo single thread boost on 13"


If people like AppleExpert can see the difference in speed between both the i5 & i7 on the 13", then it would definitely be a greater difference on the 11".


For those that want the best performance out of the MBA but with the most portability then bar the SD-CARD slot, the i7 11" is one mighty and small little package. The 'heat' topic is still early days in regards to the i7 - so I'm on the fence.

The problem with forums is that very few people who have no issues (which in actuality generally make up the majority of the buying public) post comments on forums such as this, whilst those with issues (usually the minority of the buying public) make up the majority of posters so it gives a very distorted view of things / problems. It literally can make a molehill seem like a mountain on a forum. We shall see in time if there are genuinely heat issues - but at the moment we can not rule out the possibility it could just be a few folks with bad MBA's.

Sounds good to me then. As I plan to keep for around 4 years, I think I will go for the i7. I dont need the i7 just now, but who knows what 4 years difference will make. I might also need a better CPU by then because of what I want to do.

If you don't need it now, 3 years down the line that performance difference is going to be very inconsequential compared to whatever chipset is in the 2015 revisions - so it may be a false economy upgrading it if you have no clear vision of actually using it tbh.

Well, if I get the i7, it will last longer than the i5 if the power needed keeps increasing. It the i7 becomes not enough, it will have higher resale value than the i5. I think for £86 (student discount) it is worth it for a £1300 machine.

Yes it's more powerful, but look at the leap between this revision and the last. We have geek bench scores that are 2x (100%) above the 2010 MBA revision.

But the difference between the i5 & i7 is 15-20% improvement.


If the ivy bridge leap brings quad core ulv to the MacBook airs in future revisions we may be looking at another massive performance leap in 2012-13 in which case that 15-20% improvement you paid for will be inconsequential.

If you need that performance at that stage you would be better off selling your MBA and buying a newer model.

The resale value difference will prob be negligible too.

Buy the i7 if you can for see the need or have the need for that extra bit of umpf now. Buying it because you think it will somehow future proof your device is not worth it.

Ask those users of the 11" model last year if the bump from 1.4 - 1.6 was worth it seeing as though this revision wipes the floor completely with both processor wise. That 200mhz boost did nothing to futureproof their machine. Nothing to stop that happening again...

Keep telling yourself that ;) The reality is in 2-3 years time, the fact that you paid extra for more MHz will be irrelevant. If & when power needs increase as you say, you will not be saying how clever you were getting the i7 but wanting a new machine as the difference will be marginal.

From a resale perspective, generally the cheaper machines hold their value better. Remember, the price difference to Apple between the Core i5 and Core i7 on the 13" model is about $67 based on Intel's published OEM prices (and Apple probably pays less than that), but Apple charges $100 more for it.

I decided to buy the i7 to compare with my 13" i5 base model. I use the computer for the following- MS Office 2011, Safari, Mail, iPhoto, iTunes, iLife 11, and VM Fushion running ultimate windows 64-bit.

In my unscientific tests I have yet to notice any significant difference between the machines. Sometimes the i7 appears faster and sometimes the
i5 appears faster. Once the programs are opened the first time they open at almost exactly the same speed.

Is the i7 faster? I am sure it is! Is it noticeable to the naked eye using typical day to day tasks? Not mine. Im keeping the i5 base model because for my needs I really cant tell the difference after a couple days of usage.

Also, sometimes the fans come on for 1 machine and not the other. Both were loaded exactly the same as I migrated from my base i5. The fans almost always kick on when I use iPhoto and install any program for both machines.

Buying the lower in models always seem to return more value. If your one that likes to upgrade every refresh, then go i5. Cheaper and not a big speed lost if you have to have the speed, than i7 for you. Speed wise is probably more along the lines of 10% increase.

I doubt you will see a big difference, with i7. If you can get an i5 from amazon with no tax it makes the i5 look like a better deal since your out of pocket cost will be lower than buying i7 from apple with sales tax.

It's technically correct, but somewhat simplistic since he didn't run a detailed series of tests. If AnandTech gets his hands on a Core i7 model perhaps he can include it in his review.

That said, there IS a bigger difference between the 1.6 GHz Core i5 and 1.7GHz Core i5 vs. the 1.8GHz Core i7 than the 100MHz would indicate, since the 1.7GHz model has the higher turbo boost. It depends, however, what circumstances trigger the boost and how much benefit it gives. The maximum boost figures given in the article are for a single core. The chips can also boost in dual core mode, but not as fast (I think the Core i7 boosts to 2.9GHz in single core mode, and 2.6GHz in dual core mode).

There information seems to be on par with what I've experienced from the two machines. If you need the speed or a speed freak go i7. But for most people i5 is fine.

Did an interesting test last night. Installed cs5 on both machines. No doubt the i7 won, but only by a few seconds. But after both machines cached, the apps pretty much loaded identical within each other. Now unistalling I thought i7 would win. No it was a tie. Between these to CPU, the i7 is faster but at $100 upgrade - you need to determine that. I honestly only saw about 10'ish % increase with i7. Most times almost no increase with simple task like safari or mail.

As what I recently read also it says that upgrading 11" i5 to i7 you pay $150 for 25% + speed boost and for 13" i5 to i7 you pay $100 for 10% + speed boost... well all are numbers at this time still have to wait for the more real life (let me say that) tests... Thanks for the input...

The architecture between the i5 and i7 is the same. All that's different is hat he i7 has a slightly larger L3 and a speed boost of 100/200mhz in relation to their standard/turbo speeds. Going with any of the processors for the Airs will work for "future proofing".

The Sandy Bridge Core i3/i5/i7 is a brand new architecture (it's the third variant of the Core i3/i5/i7 family). It's in a similar position now as the Core 2 Duo was in 2007. Ivy Bridge is mostly an incremental upgrade (putting it on a smaller die to improve power, and upgrading the graphics). It won't be until 2013 that the new architecture (Haswell) is available and 2014 when it becomes mainstream, so the current MacBook Air should be able to keep up with software developments for at least several years.

http://www.intel.com/technology/tick-tock/index.htm

Sandy Bridge is the latest "tock" in Intel's strategy. Nehalem (the original Core i3/i5/i7) was the previous one (with Westmere as the "tick" in between). The old Core 2 Duo was an additional "tock" back (technically a "tick" back since it was Penryn, but based on the old "tock" Merom). Confusing, but the short answer it that the Core 2 Duo vs Sandy Bridge was like a 386 compared to a Pentium for old timers on the PC side.

I did use the i5 most of the day. It did fine, but when started to import lots of photos that's where the i7 separated itself from i5. Temps were pretty much identical. It seems like the i7 does run a few degrees warmer than i5 in general. You just need to determine if the money is with the upgrade. Might I ask where are you looking to purchase? Will there be any discounts on the MBA itself?

I was just gonna go to the Apple store with my student ID so I can get the student discount. It's not as much about the $90 as it is about the trade off in speed (which can be increased in certain tasks) and battery life. Do you notice any difference in the battery life or are they pretty much the same (I feel it can't be more than a 15 minute difference)?

At the end of the day I know I'm getting an awesome computer so I really need to go get it rather than play around on here all the time and live vicariously through everyone who has one already

Did you notice any difference between the two?! I'm gonna go buy my 13" today and pretty much make a decision based on your answer haha

I was just gonna go to the Apple store with my student ID so I can get the student discount. It's not as much about the $90 as it is about the trade off in speed (which can be increased in certain tasks) and battery life. Do you notice any difference in the battery life or are they pretty much the same (I feel it can't be more than a 15 minute difference)?

At the end of the day I know I'm getting an awesome computer so I really need to go get it rather than play around on here all the time and live vicariously through everyone who has one already

They are pretty much the same. I didnt seem to much of a difference. I think I would of noticed a big difference. If the money isn't an issue, stik with i7. You will be happy you did in certain tasks. Also knowing you got the bestest and baddest MBA made! :D

I'm thinking about just getting a i5 and return the one I don't like. :)

Well money must be driving you to try both. If not you would of gone with the faster processor.

Apple expert - if you get the chance, maybe you could time and/or video a couple iMovie renders running on each, say a simple slideshow of 30-40 pics with music rendered in HD?

Right, so like an hour before I buy either an i5 or i7 model.

Help! Which one?

i7 if you can afford it. If not the i5 will do fine.

Why waste money even if you can afford it? I can afford to light hundred dollar bills on fire, but I'm not going to do that anytime soon.

Obviously you can afford it because your driving back and forth to the apple store to avoid buyers remorse.
