Screen Size and Display Comparison
Screen Size
The Apple iMac 24-Inch M1 Desktop features a 24-inch display, offering a compact footprint that fits easily on smaller desks. In contrast, the HP OmniStudio X 31.5-Inch 4K All-in-One PC provides a significantly larger 31.5-inch screen. This larger canvas allows for more workspace and better visibility for multitasking. You will notice the physical difference immediately when placing either unit on your desk. The HP model requires more surface area but delivers a more immersive visual experience. If space is limited, the Apple unit is the practical choice. If you need room for multiple windows, the HP screen is superior.
Display Resolution
Both units offer high-resolution visuals, but the technology differs. The Apple iMac uses a 4.5K Retina display with a P3 wide color gamut and 500 nits of brightness. This setup is ideal for color-critical work and vibrant media consumption. The HP OmniStudio X features a 31.5-inch 4K UHD IPS panel with 3840x2160 resolution. It also reaches 550 nits and includes an anti-glare coating. The HP screen is slightly brighter and has a three-sided micro-edge design for a bezel-less look. The Apple display has a higher pixel density due to its smaller size, while the HP offers a larger viewing area with standard 4K clarity.
Processor
Processing power varies significantly between these two machines. The Apple iMac 24-Inch M1 Desktop is powered by the Apple M1 chip, which includes an 8-core CPU. This silicon is known for efficient performance and low power consumption. The HP OmniStudio X 31.5-Inch 4K All-in-One PC uses the Intel Core Ultra 7 258V processor. This chip can boost up to 4.80 GHz and includes 24MB of Smart Cache. The Intel processor offers higher raw clock speeds and modern AI frameworks. For heavy computational tasks, the HP chip provides more processing headroom. The Apple M1 excels in optimized efficiency for macOS tasks.
Memory
System memory impacts how many applications you can run simultaneously. The Apple iMac 24-Inch M1 Desktop comes with 8GB of RAM. This amount is sufficient for basic web browsing, office work, and light media editing. The HP OmniStudio X 31.5-Inch 4K All-in-One PC includes 32GB of DDR5 5600 MHz memory. This is a substantial advantage for multitasking, video editing, or running virtual machines. The HP system can handle far more background processes without slowing down. If you plan to keep many tabs or programs open, the HP memory is far more capable. The Apple configuration is adequate for casual users only.
Storage
Storage capacity determines how much data you can keep locally. The Apple iMac 24-Inch M1 Desktop includes a 512GB SSD. This is a decent amount for most users but may fill up quickly with large video files or game libraries. The HP OmniStudio X 31.5-Inch 4K All-in-One PC offers a 1TB PCIe NVMe M.2 SSD. This doubles the storage space available on the HP unit. The NVMe drive also typically offers faster read and write speeds than standard SSDs. If you store many photos, videos, or documents, the HP storage is more practical. The Apple storage is efficient but smaller in total capacity.
Graphics
Graphics capabilities affect gaming and creative work. The Apple iMac 24-Inch M1 Desktop features an integrated 8-core GPU within the M1 chip. This provides solid performance for everyday tasks and moderate creative work. The HP OmniStudio X 31.5-Inch 4K All-in-One PC uses Intel Arc Graphics. While integrated, the Arc graphics are designed for modern workloads and AI tasks. The HP system also has more memory to share with graphics processing. For serious gaming or 3D rendering, neither is a dedicated workstation, but the HP has more raw power potential due to its larger chassis and cooler environment. The Apple GPU is optimized for macOS efficiency.
Which iMac or HP AIO suits you
Users wanting a compact and colorful setup
