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

The iPad Pro 2022 M2 Series and the iPad Pro 2024 M4 Series represent Apple's high-performance tablet offerings, designed for demanding tasks and creative workflows. While both operate on the intuitive iPadOS, the M4 series introduces a new processor, a significantly upgraded display across all models, and a refined design that sets it apart from its predecessor.

Evaluating the practical lifespan of these devices involves considering their release timelines, software support, and physical design.

• Release Timeline: The iPad Pro M2 series was released in October 2022, while the iPad Pro 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 life. [5, 2]
• Software Longevity: Both devices benefit from Apple's consistent iPadOS updates. The M4 series, being newer, is expected to support future iPadOS versions for an additional two years compared to the M2 series, offering a longer period of access to new features and security enhancements.
• Physical Design and Durability: The M4 series introduces a notably thinner and lighter design compared to the M2 models. For instance, the 11-inch M2 iPad Pro measures 5.9 mm in depth and weighs 466 grams (Wi-Fi), while the 11-inch M4 iPad Pro is 5.3 mm thin and weighs 444 grams (Wi-Fi). The 12.9-inch M2 model is 6.4 mm thick and 682 grams (Wi-Fi), whereas the 13-inch M4 model is 5.1 mm thick and 579 grams (Wi-Fi). [5, 1, 2] This reduction in thickness and weight contributes to improved portability, though the overall durability of both series is robust, featuring recycled aluminum enclosures. [5]

Both iPad Pro series offer substantial processing power, but the M4 series brings advancements that enhance performance for specific use cases.

• Processor Capabilities: The iPad Pro M2 series features an 8-core CPU and a 10-core GPU, alongside a 16-core Neural Engine. [3, 5] The iPad Pro M4 series, on the other hand, comes with either a 9-core CPU (for 256GB and 512GB storage configurations) or a 10-core CPU (for 1TB and 2TB configurations), both paired with a 10-core GPU and an enhanced 16-core Neural Engine. [1, 2, 8] This newer architecture in the M4 allows for more efficient handling of complex tasks and advanced AI features.
• Memory and Multitasking: The M2 models offer 8GB of unified memory for configurations up to 512GB and 16GB for 1TB and 2TB models. [3, 5] The M4 series maintains this structure, providing 8GB of unified memory for 256GB and 512GB models and 16GB for 1TB and 2TB models, with a higher memory bandwidth of 120GB/s compared to the M2's 100GB/s. [1, 2, 8] This increased bandwidth and optimized core distribution in the M4 contribute to smoother multitasking and faster processing for demanding applications like video editing or 3D rendering.
• Battery Behavior: Both generations are rated for up to 10 hours of web surfing or video playback on Wi-Fi. [1] However, some users of the M2 iPad Pro have reported varying battery performance, particularly with intensive use or high screen brightness. [18, 20, 23, 24] While the M4's official battery life rating is similar, its more efficient chip design may translate to better real-world endurance under heavy workloads.

The display is a significant area of differentiation, particularly for the smaller iPad Pro model.

• Display Technology and Clarity: The 11-inch iPad Pro M2 features a Liquid Retina display, which is an LED-backlit IPS LCD panel. [13, 21] The 12.9-inch iPad Pro M2, however, boasts a Liquid Retina XDR display, utilizing mini-LED technology for improved contrast and brightness. [5, 15] Both M4 iPad Pro models (11-inch and 13-inch) upgrade to an Ultra Retina XDR display with Tandem OLED technology. [1, 2, 8] This OLED technology provides deeper blacks, more vibrant colors, and a higher contrast ratio of 2,000,000:1 across both sizes, a notable improvement for the 11-inch model. [1, 8]
• Brightness Levels: The 11-inch M2 iPad Pro offers a maximum SDR brightness of 600 nits. [13] The 12.9-inch M2 iPad Pro, along with both M4 models, achieves 1000 nits of full-screen SDR brightness and a peak HDR brightness of 1600 nits. [5, 15, 1, 8] This higher brightness on the M4 models and the larger M2 model makes them more suitable for use in bright environments or for viewing HDR content. [25]
• Refresh Rate and Special Features: Both generations feature ProMotion technology, offering adaptive refresh rates from 10Hz to 120Hz for smooth scrolling and responsiveness. [1, 5, 19] The M4 series also introduces an optional nano-texture display glass on 1TB and 2TB models, designed to reduce glare in various lighting conditions. [1, 2, 8]

Both iPad Pro generations offer capable camera systems, with the M4 series introducing some user-centric adjustments.

• Rear Camera System: The iPad Pro M2 series includes a dual rear camera setup: a 12MP Wide camera and a 10MP Ultra Wide camera, along with a LiDAR Scanner. [3, 13] The iPad Pro M4 series simplifies this to a single 12MP Wide camera, retaining the LiDAR Scanner and adding an Adaptive True Tone flash for improved document scanning. [1, 2] While the M4 removes the Ultra Wide lens, its primary camera benefits from the M4 chip's image processing capabilities.
• Front Camera and Video Quality: Both generations feature a 12MP Ultra Wide front camera with Center Stage, which automatically keeps subjects in the frame during video calls. [13, 21] A key improvement in the M4 series is the relocation of the front camera to the landscape edge, which is more natural for video conferencing when the iPad is used with a keyboard. [2] Both support 4K video recording at various frame rates, and ProRes video recording is available on both, with the M2 supporting up to 4K at 30fps (1080p for 128GB models). [13, 1]
• Audio Experience: Both the M2 and M4 iPad Pro models are equipped with a four-speaker audio system, providing a rich sound experience for media consumption and video calls. [1, 11]
