Apple’s iPhone 13 is similar to last year’s iPhone 12 and despite being called iPhone 13, this is actually more of an iPhone 12S. S year models usually do not see a major design changes, instead the S year models are more refined versions of what came the previous year. One of the most recognizable changes will be a smaller display notch and the diagonally arranged camera modules, the rest of the changes will be under the hood.
Powering the iPhone 13 series is the 5nm A15 Bionic chip. 6-Core CPU with 2-high performance cores and 4 efficiency cores and 4 Core GPU.
As MKBHD pointed out, if you want to have ProRes video recording to 4K at 30fps, you need to buy anything but the base models.
iPhone 13 mini will be available for $729 and iPhone 13 will be available starting at $799 both with 128GB of storage.
