Apple 24-inch iMac M3 4.5K Retina Display, 16GB RAM, 1TB (Z19E001N3)

Overview and Performance

The 24-inch iMac with the Apple M3 chip brings fresh power under a familiar aesthetic enriching daily computing and creative tasks. Its 8-core CPU combined with the 10-core GPU marks a notable performance jump over older iMac models, delivering responsive multitasking, smooth app launches, and capable video editing and light gaming performance. The M3’s 16-core Neural Engine and hardware-accelerated ray tracing improve graphics performance and machine-learning capabilities, enhancing everything from video encoding to interactive workflows. The use of a 3-nanometer process enhances both speed and energy efficiency. The unified 16 GB memory and 1 TB solid-state drive provide ample headroom for demanding desktop use and large file storage.

Visual Experience

At its heart is the 24-inch 4.5K Retina display offering ultra-sharp 4480 × 2520 resolution supporting over a billion colors in the wide P3 gamut. With 500 nits of brightness and True Tone technology adjusting white balance to ambient lighting, the screen delivers rich visuals ideal for photo editing, streaming, and immersive viewing. The display remains a high-resolution creative canvas while doubling as a centerpiece of home or office.

System Responsiveness and Everyday Use

Everyday use feels effortless. Whether juggling numerous browser tabs, productivity apps, or video calls the system stays composed. macOS workflows are smooth, and even extended use barely stirs the cooling fan. The solid-state drive ensures quick wake-up times and fast access to data, while the 16 GB memory helps keep multiple heavy applications running.

Connectivity and Peripherals

Connectivity includes two Thunderbolt 4 / USB 4 ports with optional configurations offering two additional USB-C ports and gigabit Ethernet through the power adapter. Wireless features such as Wi-Fi 6E and Bluetooth 5.3 ensure fast network access and seamless pairing with peripherals. Setup is intuitive: plug in the matching Magic Keyboard with Touch ID and Magic Mouse and the system instantly powers up and pairs.

Camera, Audio, and Speakers

Video conferencing feels more natural thanks to the built-in 1080p FaceTime HD camera supported by an improved image signal processor delivering clearer video and better color. Audio is rich from the six-speaker system with spatial audio, while the three-mic array captures voice with clarity for reliable communication during calls or dictation.

Practical Considerations and Use Cases

For families students creators and anyone seeking a capable all-in-one desktop this iMac offers simplicity and strength. It outpaces older Intel-based iMacs and delivers enough graphics headroom for creative tasks and some casual gaming. That said it is not designed for intensive professional 3D rendering or high-end game engines where dedicated GPUs shine. Its ports are limited so users relying on many peripherals may need a docking station. The lack of height-adjustable stand may require a riser or opting for the VESA mount version.
