I haven't been able to find a definitive answer, but something close to it. Overall it seems like there's a noticeable jump from the m3 to the m5, but the difference between the m5 and m7 is not worth it. But then there are plenty of people who say to have no problems at all using the m3 for all sorts of tasks. Looking at these specs, the m3 starts at a base frequency of 1.00 GHz, the m5 is 1.2 and the m7 is 1.3. That's about it? Doesn't look like the "m" vs. "i" branding is for anything except marketing purposes, and it's the same "jump" as with the m3/m5 2016 models. I'm wondering how much difference there is between the 2017 m3 and the 2016 i5, and whether or not in practice the 2017 m3 might be fine for even more people this time around. I'm pulling the trigger on Monday no matter what. Same design so I'm trusting that the whole manufacturing process is still the same and there are no "newness" problems there. And jumping in right after the latest update feels good. Even though I don't need that much power for most of my tasks, I'm still leaning towards the i5. Planning to use this MacBook for quite a few years, and I'm worried the m3 might become sluggish just a little too fast. And if 16GB is an option with the i5/i7, that'd be a no-brainer. What are your plans?
