Thanks for the reply. That's what I was thinking myself but just needed clarification.Absolutely not. Quad cores are way too hot and inefficient for Apple to put them in the MBP. The battery life would suffer a considerable loss and people would not be able to use their laptops on their legs.
well, from the way that the processors were described to me, the reason that you would want an i7 over an i5 would be a better multitasking ability. I guess the processor distributes everything evenly over the cores (or something of that sort) so, the more cores you have, the better multitasking you can do? Just a thought...Thanks for the reply.

So is there even a justification to pay for the i7 upgrade over the i5? They literally bench marked the same.
I believe that he is asking about the differences between the i5 and i7 CPUs found in the MBP line currently. The i7-620m is not a quad core CPU.well, from the way that the processors were described to me, the reason that you would want an i7 over an i5 would be a better multitasking ability.

Apple won't go to clarksfield CPU's.Apple currently has the i7 620m processor in the 17" MBP's. Does anyone know if Apple will be releasing a new model late in the year with an i7 update to a 720-qm/820-qm?
I wouldn't if I was building a BTO; the only reason I got the i7 was it was the only way to get a 15" HR with antiglare at the Apple Store. If I were to order a machine off Apple.com I'd choose the i5 2.4GHz with the antiglare. With the money I saved, I'd have chosen a bigger SSD or something.So is there even a justification to pay for the i7 upgrade over the i5? They literally bench marked the same.
In the 17" MBP would the i5 run cooler and have better battery life over the i7?
I'm not sure of the specifics, but there are differences in both areas between the two chips. The i7 will run hotter and will adversely affect battery life versus the i5.I read that the i7 runs actually cooler than the i5 on this board. But maybe it could also be due to a bad thermal paste job.
The i5 has better battery life though.
All three CPUs hyperthead.Doesn't the i7 have hyperthreading, while the i5 does not? If so, I would think the i7 would make a lot of sense for someone who wants to keep their computer for a long time.
I'm just starting to research a replacement for my wife's 17" G4 Powerbook. Since I know she wants the same monitor size and there are lots of windows where she uses her computer, I know I'll be ordering the 17" MBP with anti-glare screen. I've been trying to figure out if I should get the i5 or i7. So many topics here talk about how the i7 really isn't worth it. However, my wife's G4 PB is 6 years old. If we keep the new computer for 6 years or more, wouldn't it make more sense to get the i7?
My thought is that the i7 will stand a better chance at holding its own 5-6 years down the road.
It's funny. I didn't know what the difference between the i5 and the i7 were, so I did some searching online and found some stuff that said the i5 didn't support hyperthreading. Maybe they were talking about a different version of the i5, or maybe I misunderstood what I was reading.
I just did what I should have done earlier and went to Apple's website and looked at the MBP page. It says:
"Built-in Hyper-Threading allows two threads to run simultaneously on each core, so Mac OS X recognizes four virtual cores instead of just two. When youre running multiple applications at once, the Core i5 and Core i7 processors spread tasks more evenly across a greater number of cores so you can get more done, faster."
So, obviously I was mistaken. In my wife's case, she doesn't do anything particularly processor intensive. On the other hand, I know darn well that we're likely to keep this computer for at least 5, maybe 6 or more years. If there's any chance that the extra capability of the i7 will make the computer "capable" in its later years, then the processor upgrade would be worth it. (It's worth noting that, not only have we kept her G4 PB for 6 years, but I just retired a G4 PowerMac last year that was 8 years old.)
