iPad Pro (2018, A12 series) vs iPad Pro (2021, M1 series)

The iPad Pro 2018, featuring the A12 series chip, and the iPad Pro 2021, powered by the M1 chip, represent two generations of Apple's high-performance tablets. Both devices are designed for demanding tasks and creative professionals, running on Apple's iPadOS. The primary distinctions lie in their processing power, display technology (especially for the larger 2021 model), and advanced camera capabilities, offering different levels of performance and features for various user needs.

When considering the longevity of these devices, several factors come into play, including their release dates and Apple's typical software support cycles.

• Release Timeline: The iPad Pro 2018 was released in October 2018, while the iPad Pro 2021 launched in April 2021. This three-year difference means the 2021 model benefits from a more recent starting point for software updates.
• OS Support Duration: Apple generally provides 5-6 years of major iPadOS updates for its devices. The iPad Pro 2018, having been released earlier, is expected to receive major software updates for a shorter period compared to the iPad Pro 2021. Users of the 2018 model might see software support conclude around 2025-2026, whereas the 2021 model is likely to continue receiving updates until approximately 2028-2029.
• Practical Lifespan: Both models feature robust build quality. While the 2021 model is marginally thicker in its 12.9-inch variant, the overall design language and materials are similar. The practical lifespan for everyday use extends beyond official software support, but newer models generally offer a longer period of optimal performance with the latest features.

The core difference between these two iPad Pro generations lies in their processing capabilities, which significantly impacts how they handle various tasks.

• Processor Capabilities: The iPad Pro 2018 is equipped with a powerful chip from the A12 series, which was highly capable at its release, offering strong performance for a wide range of applications. The iPad Pro 2021, however, integrates a desktop-class processor, delivering a substantial leap in processing power. This newer chip provides a noticeable boost in CPU and GPU performance, making it more adept at handling intensive workloads.
• Real-world Usage: For everyday tasks like web browsing, email, streaming, and light photo editing, both devices offer a smooth and responsive experience. However, for more demanding applications such as 4K video editing, complex 3D rendering, or running multiple professional-grade apps simultaneously, the 2021 model demonstrates significantly faster rendering times and a more fluid workflow. Users engaging in these heavy-duty tasks will experience a more responsive and efficient performance on the newer device.
• RAM and Storage: The 2021 iPad Pro offers increased RAM configurations, with up to 16GB available on higher storage tiers, compared to the 2018 model's maximum of 6GB. This expanded memory in the 2021 model enhances multitasking capabilities and allows for smoother operation with memory-intensive applications. Both models offer various storage options, with the 2021 model extending up to 2TB.

The display is a critical component of any tablet, and these two iPad Pro models offer distinct visual experiences, particularly in their larger variants.

• Display Technology: Both the 2018 and 2021 11-inch iPad Pro models feature a Liquid Retina IPS LCD display with ProMotion technology, offering a smooth 120Hz refresh rate, wide color support, and True Tone. However, the 12.9-inch iPad Pro 2021 introduces the Liquid Retina XDR display, which utilizes mini-LED technology. This advanced display provides significantly higher peak brightness, especially for HDR content, and a much greater contrast ratio compared to the IPS LCD panels.
• Brightness and Clarity: The 12.9-inch 2021 model's Liquid Retina XDR display can achieve up to 1000 nits of full-screen brightness and 1600 nits peak brightness for HDR content, offering a more vibrant and immersive viewing experience for movies and professional creative work. The 2018 model and the 11-inch 2021 model typically reach 600 nits of brightness.
• Viewing Experience: While both displays offer excellent clarity and color accuracy, the mini-LED technology in the 12.9-inch 2021 iPad Pro provides deeper blacks and more precise local dimming, enhancing the visual impact of high-dynamic-range content. Users who prioritize media consumption or color-critical work will find the 12.9-inch 2021 display a notable upgrade.

The camera systems on these iPad Pro models have evolved, with the 2021 version introducing several enhancements for both photography and video conferencing.

• Rear Camera System: The iPad Pro 2018 features a single 12MP wide-angle rear camera capable of 4K video recording. The iPad Pro 2021 upgrades this with a dual-camera system, including a 12MP wide and a 10MP ultra-wide lens, along with a LiDAR Scanner. The LiDAR Scanner improves autofocus in low-light conditions and enhances augmented reality (AR) applications.
• Front Camera and Video Calls: The 2018 model has a 7MP TrueDepth front camera. The 2021 model significantly improves the front-facing camera to a 12MP ultra-wide TrueDepth camera, which enables the Center Stage feature. Center Stage automatically keeps the user in the frame during video calls, even as they move around, and expands to include other participants.
• Audio Quality: Both devices feature a four-speaker audio system, providing a rich sound experience for media consumption. The 2021 model's speakers offer improved bass definition and a fuller sound.
