What is the difference between an iPhone 12 and 13? Which should I purchase?

• Both the iPhone 12 and 13 feature a 6.1-inch OLED Super Retina XDR display with HDR, True Tone, P3 broad colour, and Haptic Touch. The sole difference between the iPhone 13 and the iPhone 12 is that the iPhone 13's display can get 175 nits brighter during normal non-HDR use, but this isn't a compelling reason to upgrade.
• The iPhone 12 is equipped with Apple's A14 Bionic chipset, whilst the iPhone 13 has the latest and most powerful A15 Bionic chip. The A14 and A15 Bionic chips both have 6-core CPUs with two performance cores and four efficiency cores. Both come with a 4-core GPU and a 16-core Neural Engine.
• The notch screen refers to a cutout in the top of the screen that is used to house the front camera and sensors. Over the years, the notch display has become a popular feature, which is loved by some users but despised by others. On iPhone 13, there may be a minor difference. Apple's supplier unveiled new sensor technology that will aid in the creation of a smaller notch. The notch on the iPhone 13 may be about 20% smaller than the notch on the iPhone 12.
