Choosing between the iMac M3 and iMac M4 isn’t always straightforward.
On paper, both are powerful all-in-one desktops. In practice, the difference shows up when you’re deep in a timeline, pushing effects in After Effects, or waiting on a 3D render.
Some teams need a cost-efficient machine that handles day-to-day design and editing without fuss. Others want the newest hardware that can crunch through 8K footage or AI-driven workflows without slowing down.
If you’re renting, the decision isn’t only about performance. It’s also about budget, project duration, and how quickly you need the machines delivered. That’s where Rank Computers helps creative teams make the right call – giving you access to both iMac M3 and iMac M4 setups without the overhead of buying outright.
The iMac M3: Reliable Power for Everyday Creative Work
Released in late 2023, the iMac M3 marked a big leap for Apple’s all-in-one desktop. It delivered workstation-level performance for teams used to Intel-based iMacs or even the first M1 chips.
Key Features
- Chipset: Built on a 3nm process, the M3 packs up to 8 CPU cores and up to 10 GPU cores.
- Display: A 24-inch 4.5K Retina display with 500 nits brightness, P3 wide colour, and True Tone for consistent, accurate visuals.
- Memory: Unified memory up to 24GB, with 100GB/s bandwidth. Ideal for running multiple creative apps at once.
Performance in practice
- Smooth handling of Adobe Creative Suite (Photoshop, Illustrator, InDesign).
- Fast rendering of 4K timelines in Final Cut Pro.
- Responsive animation playback in After Effects at small-to-mid project scales.
Best Use Cases
- Graphic design studios working on branding, UI/UX, and marketing materials.
- Photo editing and retouching with large RAW files.
- Small-to-mid-scale video production at 1080p or 4K.
If your work rarely stretches beyond these boundaries, the M3 iMac delivers strong value at a lower rental cost.
The iMac M4: Built for the Next Wave of Media Workflows
The iMac M4, launched in 2025, builds on the M3 foundation but pushes performance towards heavier, future-facing workloads. Apple designed the M4 series with AI integration, advanced GPU features, and larger memory capacity in mind.
Key Features
- Chipset: The M4 chip includes improved CPU and GPU cores, delivering higher efficiency and performance for multitasking and media-heavy applications.
- GPU Upgrades: Hardware-accelerated ray tracing and mesh shading. This significantly speeds up 3D rendering, AR/VR development, and advanced motion graphics.
- Neural Engine: More powerful AI acceleration for tasks like smart object selection, live background replacement, and AI-based upscaling in creative apps.
- Memory: Higher unified memory configurations with greater bandwidth. Essential for editing 6K/8K video projects or large-scale 3D models.
- Thermals and efficiency: Improved energy management means you can push the system harder without throttling.
Performance in Practice
- Handling multi-cam 8K ProRes video editing in Final Cut Pro or Premiere Pro without dropped frames.
- Running Cinema 4D, Blender, or Maya with complex 3D scenes.
- Real-time playback of advanced After Effects compositions with multiple layers and effects.
- Faster export and render times compared to the M3, saving hours on large projects.
Best Use Cases
- Studios experimenting with AI workflows: automatic object removal, generative image fills, AI-based motion tracking.
- Post-production teams handling cinematic or advertising content, where hours saved in rendering directly reduce delivery timelines.
- AR/VR creators building immersive experiences that blend 3D assets with AI-generated environments.
- Agencies running high-throughput pipelines, where AI tools reduce manual editing and free up teams for creative work.

Which iMac Should You Rent?
The answer depends less on specs and more on what kind of media work your team is handling.
- Rent an iMac M3 if:
- Your workload is centred on design, photo editing, or light-to-mid video editing.
- You want a cost-effective rental that still delivers professional results.
- You don’t need advanced AI or 3D rendering features.
- Rent an iMac M4 if:
- Your projects demand cutting-edge performance, such as 8K video or complex 3D animation.You want access to the latest hardware for longer rental cycles.Your team is experimenting with AR/VR, real-time effects, or AI-driven creative workflows.
Final Thoughts
Both the iMac M3 and iMac M4 can handle design and media projects, but they’re built with different levels of intensity in mind. The M3 remains an excellent choice for everyday creative tasks, while the M4 is geared toward professionals pushing into high-end production.
With Rank Computers, you don’t just rent hardware. You get the flexibility to scale up or down, access to the latest Apple desktops, and the confidence that your team’s creative output won’t be held back by slow machines.
