iPad Pro (2022, M2 series) Vs iPad Pro (2024, M4 series)

When considering the longevity of these devices, several factors come into play, including their release timelines and expected software support.

• Release Timeline: The iPad Pro 2022 M2 Series was released in October 2022, while the iPad Pro 2024 M4 Series launched in May 2024. This two-year difference means the M4 models will likely receive software updates for a longer duration, extending their functional lifespan.
• Software Longevity: Both devices are built to last, but the M4's newer hardware platform provides a longer runway for future iPadOS updates and compatibility with increasingly demanding applications.
• Repairability: Both generations feature durable aluminum enclosures. While Apple devices generally have moderate repairability, iFixit's teardown of the M4 iPad Pro indicates some improvements in battery replacement accessibility compared to previous generations, though the ultra-thin design still presents challenges for other component repairs.

Both iPad Pro series offer robust performance, but the M4 models introduce notable advancements in processing capabilities.

• Processor Capabilities: The iPad Pro 2022 M2 Series handles demanding applications, complex multitasking, and creative workflows with ease, offering strong performance for its generation. The iPad Pro 2024 M4 Series, however, delivers a significant leap in processing power, particularly for professional applications, advanced graphics rendering, and on-device artificial intelligence tasks.
• Multitasking and Responsiveness: Both devices manage multiple applications smoothly. The M4 models provide more performance headroom, which can be beneficial for intensive background processes and future software advancements.
• Storage Options: The M2 models offered storage starting from 128GB, while the M4 models begin at 256GB, with both generations offering configurations up to 2TB. Higher storage tiers on the M4 also come with increased RAM.

The display is a key differentiator between these two generations, with the M4 Series introducing a new technology.

• Display Technology: The 11-inch iPad Pro 2022 M2 Series features a Liquid Retina LCD, while the 12.9-inch model uses a Liquid Retina XDR mini-LED display, known for its high brightness and contrast. The iPad Pro 2024 M4 Series, in both its 11-inch and 13-inch models, features the new Ultra Retina XDR display, which utilizes tandem OLED technology. This results in exceptional brightness, deeper blacks, and superior contrast.
• Brightness and Clarity: Both generations offer high resolution for sharp visuals. The M4's Ultra Retina XDR display achieves 1000 nits of full-screen SDR brightness and up to 1600 nits peak for HDR content, a notable increase in sustained brightness compared to the M2's 600 nits SDR.
• Refresh Rate: Both models incorporate ProMotion technology, providing adaptive refresh rates up to 120Hz for smooth scrolling and responsive interactions.

Both iPad Pro generations feature capable camera systems designed for various tasks, though there are some distinctions.

• Rear Camera System: The iPad Pro 2022 M2 Series includes a dual-camera setup with a 12MP Wide and a 10MP Ultra Wide lens. The iPad Pro 2024 M4 Series features a single 12MP Wide rear camera, omitting the Ultra Wide lens found on its predecessor. Both include a LiDAR scanner for enhanced augmented reality experiences and depth sensing.
• Front Camera: Both generations feature a 12MP Ultra Wide front camera with Center Stage. A practical improvement on the M4 models is the repositioning of the front camera to the landscape edge, which is more convenient for video calls when the device is used with a keyboard.
• Video Recording: Both are capable of recording high-quality video, with the M2 supporting ProRes video capture and transcoding. The M4 also supports 4K video recording.

Beyond core performance and display, several other features contribute to the overall user experience of these iPad Pro models.

• Design and Dimensions: The iPad Pro 2024 M4 Series is notably thinner and lighter than the iPad Pro 2022 M2 Series. For instance, the 13-inch M4 model is 5.1mm thin and weighs 579g (Wi-Fi), making it Apple's thinnest device to date, compared to the 12.9-inch M2 model at 6.4mm and 682g (Wi-Fi).
• Connectivity: Both generations support Wi-Fi 6E for fast wireless internet and Bluetooth 5.3 (M2) or 5.3/5.4 (M4) for accessories. Cellular models in both series offer 5G connectivity.
• Ports and Biometrics: Both devices feature a USB-C port with Thunderbolt/USB 4 support for high-speed data transfer and external display connectivity. Face ID is used for secure authentication on both.
• Accessories: While both support Apple Pencil and Magic Keyboard, the M4 Series introduced the Apple Pencil Pro with new gestures and a redesigned Magic Keyboard with a function row and aluminum palm rest.
