The new macbooks start with 10th gen Intel core i3 and can go as high as the quad core i7.
The base model can handle basic activities like browsing, multimedia and some light photo editing in lightroom with minor hiccups here and there although the i5 model is more recommended.
The 10th gen core i5 is a quad core processor which makes it a much better option than the dual core i3. Daily activities feel snappy and fast with good app opening speeds and shorter render times in lightroom. The i5 model can do some 1080p video editing on Final Cut if you are into videos.
You can get the top of the line i7 model which can do decent 4k editing but at that price the MacBook pro makes more sense.
Let’s be real no one buys Macbooks for gaming unless you are planning to play the Arcade games from Apple but the new Iris graphics does help improve the render times.
All MacBooks are still pretty silent due to the fanless design.
