Hi there.
I'm considering a retina 13'' and I wonder if i would choose the i7 option. I wouldn't really if the 13'' would have some kind of discrete GPU.
1. Since it's not the case and I think have read that integrated graphics like HD4000 speeds are related to the CPU you have, am I right that the i7 which runs quickier will also feature a speedier Hd4000 ? Since its the only graphic power we can have it's a good reason to consider the upgrade isn't it, apart from the extra cache?
2. If so, would those speeds be configurable to be "overclocked" later anyway, therefore breaking a bit this reason to buy the i7 over the i5..
3. Also, does the i7 which is labeled at higher speed clocks, will at idle be systematicly running quickier ? Will it affect temperature?
4. I also saw that the i7 fan runs at 3400rpm min VS 2000rpm for the i5. Is it true and is it noticeable really?
Is it tweakable later like putting it to 2000rpm also on the i7 and limiting the max speed so it will not get too hot?
Thanks a lot for your answers.
