The answer is, a lot more than you might think. First you get a much brighter, Mini-LED display. You also get about 33 percent better battery life, along with an extra USB-C port, an HDMI port, and an SD card reader. This year’s model also has a 2X faster SSD, 25 percent faster memory bandwidth, and what Apple calls “Neural Accelerators.”

While it looks a lot like the previous model, that's a good thing in this reviewer's opinion, and the new silicon gives you even more processing power.
