24-inch iMac with Retina 4.5K display: M3 chip

Solid-state drive (SSD) storage is the amount of space your iMac has for your documents, photos, music, videos, and other files.

It delivers significant performance and speed that you’ll notice when you start up your iMac, launch an app, or browse your photos.

Unified memory (RAM) increases performance and enables your iMac to perform better and at a higher speed.

The more memory you choose, the more apps you can run simultaneously with a higher rate of performance.

Thunderbolt ports provide high-performance options for connecting accessories, external drives, cameras, displays, and more.

Two additional USB 3 ports let you connect external devices for data transfer, charging, and syncing.
