Which is Better for Editing 4K Raw Footage: 21.5" 4K iMac with i7 or 27" 5K iMac with i9?

When considering the best iMac for 4K raw footage editing, deciding whether to go for a maxed out 21.5" 4K iMac with an i7 processor or a mid-tier 27" 5K iMac with an i9 processor can be a tough choice.

The 5K Screen Design for 4K Editing

The 5K screen is often touted as the best for 4K editing due to its larger size. It is designed to accommodate a full-screen view of your 4K raw footage, allowing you to see every detail clearly. Additionally, it still provides enough space to keep the Dock and Menu bar visible, which enhances productivity. However, with a 21.5" 4K iMac, you may find that the screen size feels more manageable and the dock and menu bar can become less intrusive.

Technical Performance: i9 vs. i7

From a technical perspective, both iMac models offer excellent performance. The mid-tier 27" 5K iMac with an i9 processor might appear more powerful, but this alone does not guarantee superior performance for 4K raw footage editing. The i9 processor is highly capable, but the real performance difference often comes down to the rest of the system. Here are some key considerations:

Storage and RAM: Ensure you have sufficient RAM and fast storage to handle large 4K raw files efficiently. Graphics Card: Apple's integrated graphics might be sufficient for basic 4K editing, but if you plan to work with complex projects, you might need an external GPU for better performance. Software Optimization: Choose the right software and make sure it is optimized for your hardware. Adobe Premiere Pro, DaVinci Resolve, and Final Cut Pro are some popular choices for 4K editing.

Advanced Editing with 27" 5K iMac

The 27" 5K iMac with an i9 processor can provide a more immersive editing experience. Its larger 5K display allows you to work with multiple timelines, view larger project timelines, and access more useful tools without scrolling. The larger screen can also be beneficial if you are working on multiple layers or if you need to open additional image or color workflow applications.

Practical Considerations: 21.5" 4K iMac with i7

On the other hand, the maxed out 21.5" 4K iMac with an i7 processor offers a more compact and potentially more portable option. Its smaller size can be advantageous if you frequently need to move your work to different locations. It may also be less expensive, and if you find that you have good enough performance from an i7, it can be a more cost-effective choice.

Experimenting with Both Options

Both iMac models are fantastic for editing, and the i9 technically is better, but it's crucial to test both options with your specific workload to determine what works best for you. Start by setting up a few sample projects and evaluating how each system performs. Consider factors such as:

Rendering time and overall speed. Smoothness of the user interface and responsiveness. Convenience and comfort during extended periods of use.

Ultimately, the best option depends on your specific needs, budget, and workflow. If you have the budget for it and prioritize a more immersive editing experience, the 27" 5K iMac with an i9 is a powerful choice. However, for a more compact and cost-effective solution, the 21.5" 4K iMac with an i7 can still provide excellent performance.

Conclusion

While the 5K screen of the 27" iMac is designed for 4K editing and enhancing the editing experience, the real decision often comes down to personal preference, budget, and specific tasks. Whether you choose the 21.5" 4K iMac with an i7 or the 27" 5K iMac with an i9, the key is to find the balance that meets your needs for the best 4K raw footage editing experience.

Whether you're a professional editor or a hobbyist, investing in the right system can significantly impact your productivity and the quality of your work. Make sure you do thorough research and testing to make an informed decision that fits your workflow and goals.
