Is it worth it to take 1.3 Ghz?

I mean for Macbook 2015 12" Retina. I am considering the options between 1.2 Ghz or go to the top 1.3 Ghz configuration. I red many reviews that to some extend the processor and the graphic are underpowered but do additional 0.1 Ghz really makes a difference?

Typical scenario are microsoft office 2016, browsing and youtube-ing, and occasionally photo/image manipulating with photoshop.

For the usage you're describing, the base 1.1 GHz is sufficient. Do mind though that superior configurations aren't just 0.1 GHz more each. As well as the base frequency, you have to look at Turbo Boost frequencies too, where the differences are wider from one model to another (see specs). And that criterion matters more IMO. Look at this analysis of the Core M.

I only got the 1.3 because since I already ruled out the 256GB storage model, it was only around 150 bucks more to step up to the next processor. Since I like to keep machines for a couple of years, it felt like paying only that small amount extra was worth it to keep the machine feeling a bit more current once it gets surpassed by faster ones. If you want a 256GB storage model, then the decision is not quite as easy.

btw one thing to keep in mind: It's a little misleading to think of it as only a 0.1 GHz increase. Turbo boost seems to play a fairly big role in the actual performance you experience on machines these days, especially with the core M. From what I understand, this kind of CPU tries to idle as much as it can so the base clock speed is really just what you notice when the computer isn't being asked to crunch anything significant. But the 1.3 model's turbo speed is 2.9 GHz, whereas the 1.2's is 2.6 and the 1.1's is 2.4. It's still not a massive difference, but since this is the speed that counts when the computer is being pushed to work on heavier tasks, it's a little more of a significant step up in speed than what looking at the base clock speed would suggest.
