Spec Comparison: iMac M4 vs 27-Inch
processor performance
The Apple iMac 24-Inch M4 All-in-One uses the Apple M4 chip with an 8-core CPU. This Apple Silicon architecture is designed for high efficiency and modern tasks, including Apple Intelligence features. The Apple iMac 27-Inch Retina 5K relies on a 10th-generation Intel Core i5 processor with six cores. While the Intel chip is capable, the M4 represents a newer generation of technology. You will likely notice smoother multitasking and better power efficiency with the M4 model compared to the older Intel-based system.
graphics capability
Graphics performance differs significantly between these two machines. The 24-inch M4 iMac features an integrated 8-core GPU within the M4 chip. This unified architecture allows the CPU and GPU to share memory efficiently. In contrast, the 27-inch model uses the AMD Radeon Pro 5300 graphics card. For general creative work and gaming, the M4 GPU offers modern optimization and support for newer APIs. The dedicated AMD card in the 27-inch model is still competent, but the M4 provides a more contemporary graphics experience for current applications.
display size
Screen real estate is the most obvious physical difference. The Apple iMac 27-Inch Retina 5K offers a 27-inch diagonal display with a 5120-by-2880 resolution. This larger canvas is ideal for video editing timelines or detailed photo work. The Apple iMac 24-Inch M4 All-in-One features a 24-inch 4.5K Retina display. While still sharp and vibrant, it provides less workspace. If you need more room to spread out your windows and tools, the 27-inch model is the clear choice. For compact desks, the 24-inch fits better.
system memory
Memory capacity affects how many applications you can run simultaneously. The Apple iMac 24-Inch M4 All-in-One comes with 16GB of Unified Memory. This ample amount supports heavy multitasking and large files without slowing down. The Apple iMac 27-Inch Retina 5K is listed with 8GB of RAM. This lower capacity may limit your ability to run multiple demanding apps at once. If you plan to keep many browser tabs and creative software open, the 16GB in the M4 model offers a more comfortable buffer for future-proofing.
storage capacity
Both computers use fast SSD storage, but the base capacities differ. The Apple iMac 27-Inch Retina 5K includes 512GB of SSD storage. This provides more space for your operating system, applications, and media files right out of the box. The Apple iMac 24-Inch M4 All-in-One is configured with 256GB of SSD storage. While still fast, you will fill this space quicker. If you store large video projects or extensive photo libraries locally, the 27-inch model gives you double the starting room without needing external drives.
build and design
The physical footprint and aesthetic vary between the models. The 24-inch M4 iMac is strikingly thin and comes in seven vibrant colors, including pink, green, blue, and silver. It weighs 9.74 pounds and stands 18.1 inches tall. The 27-inch Intel iMac is heavier at 19.7 pounds and has a different height profile. It typically comes in silver. The M4 model is designed to be a colorful centerpiece in modern spaces. The 27-inch model offers a more traditional, larger desktop presence. Choose based on your desk size and color preference.
Which iMac model suits your needs?
Users wanting modern AI and portability
The 24-inch M4 model features Apple Intelligence support and a lightweight design. Its 16GB of unified memory handles multitasking efficiently. The 12MP camera and six-speaker audio system provide superior communication and media experiences. You get a compact footprint that fits easily into smaller workspaces while maintaining high performance for daily tasks.
Professionals needing large high-res displays
The 27-inch Retina 5K display offers significantly more screen real estate and pixel density. This larger format is ideal for detailed video editing, graphic design, or split-screen workflows. The 5120-by-2880 resolution ensures sharp text and vibrant colors. You benefit from a substantial workspace that minimizes the need to switch between windows frequently.
Those prioritizing storage capacity
This model includes 512GB of SSD storage, which is double the capacity of the base M4 unit. You can store more local files, videos, and applications without relying on external drives. The AMD Radeon Pro 5300 graphics card also supports dedicated video processing tasks. This setup is practical for users with large media libraries or project archives.
Budget-conscious buyers seeking value
The 2020 iMac often presents a lower entry point for acquiring a large all-in-one system. You receive a 27-inch display and a capable Intel Core i5 processor for creative work. While it lacks the latest silicon, it still delivers strong performance for standard productivity and media consumption. This option allows you to access a larger screen at a reduced cost.
