Apple's refreshed M4 24-inch iMac sports a fast chip, but that isn't the only reason to upgrade. Here's how the hot new model compares to the year-old M3 iMac that it replaces.

Apple's latest MacBook Pro sports more ports and RAM for the same starting price. While the base model is short on RAM and ports, Apple's M3 MacBook is still a portable powerhouse.

Compared to the M3 chip, the M4 chip has an extra 3 billion transistors and more memory bandwidth, great for faster processing speeds. For most devices, it also has a higher max memory capacity than the M3 chip. The only exception here is the iPad Pro, which has a max memory capacity of 16GB due to its own limitations.
