If you’re considering making the jump to Google’s newly announced Pixel 3 and Pixel 3 XL, you’re in the right place. Whether you’re a Pixel 2 owner eyeing greener pastures or a bargain type hunting for a last-gen smartphone that’s still top of the line, comparing new and old is often useful.

On specs alone, the Pixel 3 shares most of its DNA with the Pixel 2, but there are a handful of meaningful differences and they’re not all obvious. What is obvious: The Pixel 3’s AMOLED screen is now 5.5 inches compared to the Pixel 2’s 5 inch display. The Pixel 3 XL now offers a 6.3 inch display, up .3 inches from the Pixel 2 XL.
