does the 17 run cooler than the 15? how about i5 vs i7 for heat?
I think there would be little to no difference, not that it actually matters.
i think it is important to understand the difference between the macbook lines re heat and battery life. those factors are more important to me than speed for what i do.
I think i7 should generate more heat.
The 17" has more space for cooling, so it'll be a bit cooler.
The i7 will run a bit more hot than the i5, so the i5 will be a bit cooler.
Important to note: this is only when you're stressing all the cores. Most of the time 2-3 or your cores will be completely asleep doing nothing, and your MacBook will be cool and dead silent, regardless of the size/CPU. Bottom line: don't worry and buy what you need.
I would say this is pretty accurate, but not 100%. Both i7, i5's have a 35w tdp, and while the i7 should operate at a higher Turbo Boost clock, neither stays there very long.
Out of the 5-10 machines Ive seen of each, there was no correlation between heat and i7, or a cooler i5.
Oh and, only 2 cores for each chip
Thought quad core?
The i5 has better battery life.
you are right!
here is a link re battery life i was surprised how much better c2d and i5 is than i7.
The i7-620m is a dual core chip. Quad cores have much lower clock speeds.
I think it's due to the bigger screen that the 2010 13 MBP is so good with battery life. ( and maybe the dedicated GPU doesn't use 0 Watts when it is not activated )
The i5 beats the 2009 15 inch C2D MBP in battery life
They also run hot enough to roast a steak on.
...But also smacks around all dual cores on multi core threaded programs and benchmarks.
no doubt, i5 gets pretty good battery life.
anyone pick i5 over i7 for better battery life?
