Hey guys, I need to know if is there a huge performance difference between i5 2.4 and 2.6 in terms of graphics performance, speed and battery life? More importantly, I'm more concerned with the battery life. Thanks so much for your time.

Depends on what you're using the laptop for.

The 2.6 does have ~10% better GPU performance which will aide in running the retina display a tad bit better than 2.4 would.

I doubt it, what will you be using it for?

Hmm... let's see...word processing,more towards photo editing, some video editing, a lil bit of music production and most of the time, web browsing.

To be more precise, the 2.6 i5's Iris GPU maxes out at 1,200 MHz, which is 100 MHz faster than the 2.4 i5's Iris.

does it mean the 2.4 will consume lesser battery than the 2.6? because I've been lurking around the 15" rmbp threads and those who are using 2.6 are experiencing more battery consumption than the 2.0 either due to higher clocks in the cpu or gpu. I'm assuming the 2.4 will have more battery life compared to 2.6 and 2.8? :confused:

That's a great question. I would guess that battery consumption would be about the same—the faster CPU would finish its work sooner, and thus it would spend more time in an idle state. I assume the dGPU on the highest-end rMBP is what drains the battery faster, but I really don't know.

And by the way, the 2.4ghz CPU will be more than enough for what you're doing.

I don't think there's much of a difference (and I haven't seen enough posts about it to believe it's a problem yet) and there shouldn't be.

Anyway you don't need the 2.6GHz at all, I say get the 2.4GHz.

Yeah, I'd ordered the 2.4/8/128 2 days ago. Should be here today or tomorrow. Worse come to worst, i'll return and reorder the one with 2.6 :p

I had the same concern, got my 2.4/8/256 a couple of days ago and I see no reason whatsoever that anyone would need to go with the 2.6. People think it makes a difference and in spec test it does, but in real word use.... not even noticeable. You did the right thing in saving your money! :)

ahhhhh... gooodie! i'd like to ask you a question if you don't mind. How long are you getting on battery? >9 or <9 hours?

I have used the heck out of this thing since I got it, just loving the retina display. Today, I got about 9 hours and 32 minutes before I had to recharge it. I have been basically using it on an off during the day, but what I did was set my timer on my phone each time I'd start using it, which is how I got the total time. The day before I had watched a couple of full movies and only ended up getting 8 hours and 22 minutes. So the battery life is very close to what is stated from my use. I keep the display at about 5o to 60 percent, which is plenty bright. The screen on full brightness hurts my eyes.

Good luck with yours!

nice! Hopefully mine won't have defects like touchpad and IR or any undiscovered problems. :D

Thus far I've not even had the freezing issue that so many have experienced, so its been great! Another full day and zero problems with great battery life. I started using this thing at 7 AM this morning and it now 10:45 PM and I got 18% battery life.

I've just received mine today and my gosh, it's so tiny and light! I'm starting to love it more than my 15" now. hahaha. I've been having a lot of page outs and what's sad is I only had safari opened with 6 tabs and a movie playing. I tried the purge command in terminal but freed up a little memory only. Hopefully it's a Maverick issue. :cool:
