Specs: Screen, Chip, Memory, Weight
Processor performance
The Apple iMac 27-Inch Retina 5K uses a 3.3GHz 10th-generation Intel Core i5 processor. This is a traditional x86 architecture chip that relies on high clock speeds for task execution. The Apple iMac 24-Inch M4 features the Apple M4 chip with a 10-core CPU. Apple Silicon is designed for efficiency and parallel processing. The M4 generally offers better performance per watt. You get faster response times in creative apps. The Intel chip may feel more familiar to some users, but the M4 is the newer technology.
Graphics capabilities
Graphics handling differs significantly between these two models. The 27-inch model includes an AMD Radeon Pro 5300 graphics card. This is a discrete GPU option suitable for moderate creative work and gaming. The 24-inch M4 model relies on a 10-core GPU integrated into the M4 chip. While integrated, Apple Silicon GPUs are highly optimized for macOS. The discrete AMD card in the larger iMac may offer more raw power for heavy rendering. However, the M4 GPU is sufficient for most everyday tasks and light gaming.
System memory
Memory capacity affects how many applications you can run simultaneously. The Apple iMac 27-Inch Retina 5K comes with 8GB of system memory. This is the base configuration and may limit multitasking with large files. The Apple iMac 24-Inch M4 includes 24GB of Unified Memory. This is a substantial increase, allowing you to keep more apps open without slowing down. Unified memory allows the CPU and GPU to share data efficiently. For heavy workloads, the 24GB option in the M4 model is clearly superior.
Display size and resolution
Screen real estate is the most visible difference. The 27-inch model features a 27-inch Retina 5K display with a resolution of 5120-by-2880 pixels. This provides a large canvas for detailed work. The 24-inch model has a 24-inch 4.5K Retina display. It offers 500 nits of brightness and supports up to 1 billion colors. While the 5K resolution is sharper, the 27-inch screen gives you more space to arrange windows. The choice depends on whether you prioritize screen size or the newer color technology.
Physical footprint and weight
Desk space matters for many buyers. The 27-inch iMac is larger, measuring 25.6 inches wide and 20.3 inches high. It weighs 19.7 pounds. The 24-inch M4 iMac is much more compact. It measures 21.5 inches wide and 18.1 inches high, weighing only 9.79 pounds. The smaller model is strikingly thin and comes in seven vibrant colors. If you have limited desk space, the 24-inch model fits perfectly. The larger model requires a more substantial desk area to accommodate its size and weight.
Storage capacity
Both computers include 512GB of SSD storage in the configurations listed. This provides ample space for the operating system, applications, and a moderate amount of personal files. Both use ultrafast SSD technology for quick boot times and file transfers. Since the storage capacity is identical, this aspect does not differentiate the two models. You will need external storage or cloud solutions if you plan to keep large video projects or extensive photo libraries on the machine itself.
Which iMac model fits your needs
Users wanting modern features and portability
The 24-inch M4 model weighs under 10 pounds and includes a 12MP camera with Spatial Audio. You get 24GB of unified memory for smoother multitasking. The 4.5K Retina display offers 500 nits of brightness. This compact design fits easily into smaller spaces while supporting Apple Intelligence features.
Users prioritizing screen real estate and resolution
The 27-inch Retina 5K display provides a higher pixel density of 5120-by-2880 resolution. This larger screen suits detailed photo editing or spreadsheet work. The Intel Core i5 processor offers traditional performance. You get two Thunderbolt 3 ports for connecting multiple high-speed peripherals to this larger desktop setup.
Buyers seeking the latest silicon efficiency
The M4 chip delivers faster performance per watt compared to older Intel processors. You benefit from advanced media engines and enhanced security features. The all-in-one design integrates speakers and mics directly into the thin chassis. This model supports modern macOS capabilities and offers a more energy-efficient computing experience for daily tasks.
