The inclusion of the Apple A15 Bionic chip, the most powerful mobile processor available from Apple and a CPU Apple claims to be 50% faster than any other competitor, is worth mentioning. The Pro Max and Pro Max both have an upgraded 5-core GPU. This, along with a 120Hz display, upgraded battery and improvements in camera sensors, makes the Pro Max and Pro Max very powerful.
Apple iPhone 13 Pro max: $1,099 449 with eligible trade in at Apple (opens up new tab). Unlocked devices will only allow you to purchase a new Apple product directly. Apple also offers iPhone 13 Pro Max deals. This includes a trade in rebate of up to $650. Although it isn’t the largest on the market, it’s enough to save a good chunk of the price. Unlocked devices are a good option if your plan is flexible. Total cost $449 (maximum saving).
When scrolling on The New York Times homepage using the iPhone 13 Pro Max and iPhone 12 Pro Max simultaneously, I was able to read text more clearly on Apple's newer smartphone by quickly scrolling between the displays. It feels much more responsive.
