MBP 2.2 vs 2.5, yet another question...

[root.root]

I still didn't decide to go for the 2.2 or the 2.5 MHz.

- don't care much about graphics
- interested in CPU perf, but does it really make a difference.. (many Q&A about that)

However, my question is related to Battery, graphics card and Weight.

The Apple page states that

- both have 9 hours autonomy
- both weight 4.49 pounds (2.04 kg)

but the 2.5 has an AMD graphics card and a stronger CPU (more battery for same autonomy)

At the very bottom of the Apple page, a note about the weight:

"Weight varies by configuration and manufacturing process"

So, can I expect a - at least - slightly lighter MBP by choosing the 2.2?

No noticeable difference. Don't worry about it.

The weight difference is negligible. Both the 2.2 and 2.5 are quad cores i7.

Unless you're dealing with large video files/photos where processing times matter, you will most likely never notice the difference.

Based on Apple's recent track record with dGPUs, I would recommend going for the 2.2.

You will not be able to tell the difference in weight ... I mean come on, do you know how light a laptop GPU is compared to the rest of the 4.5 lb body?

Actually my reasoning was:
- more CPU power
- more GPU power
- same battery life (9 hours)

=> more battery - which is heavy!

Oh, both models have the same battery.

The battery is the exact same. Any weight difference would be in the extra chip (the dGPU). And honestly, if you can actually feel that, I can suggest a good shrink for you.

I can suggest a good shrink for you.

Please!
