Apple Unveils New M4 Chip in Updated iPad Pro

Apple has introduced the M4 chip, powering a redesigned iPad Pro that blurs the line between tablet and laptop. The new device features a slimmer design, an OLED display for the first time, and support for Apple’s upcoming external display, the Studio Display for iPad. The M4 marks the third generation of Apple’s custom silicon for its mobile and desktop devices, following the M1 in 2020 and M2 in 2022.

The chip itself uses a 3-nanometer manufacturing process, making it more power-efficient and faster than its predecessors. Apple claims the M4 offers 50% better performance than the M2 at the same power level, with significant improvements in machine learning tasks and graphics rendering. It includes a 10-core GPU and a 16-core Neural Engine, enabling complex AI processing directly on the device.

One of the most notable additions is Apple Pencil Pro, a redesigned stylus with haptic feedback, squeeze gestures, and USB-C charging. It pairs magnetically with the new iPad and supports hover detection, allowing users to see cursor previews before touching the screen. The Pencil connects via Bluetooth and draws minimal power, lasting weeks on a single charge.

iPadOS 18, shipping later this year, unlocks new multitasking features tailored to the M4’s capabilities. Users can resize app windows freely, snap them to screen edges, and create desktop-style workflows. A redesigned sidebar system across apps like Notes and Mail improves navigation, while the addition of native JavaScript support in Safari opens the door for more powerful web apps.

Background: The Evolution of Apple Silicon

Apple’s shift to its own processors began in earnest in 2020 with the M1 chip, a key moment that ended over a decade of reliance on Intel processors for Macs. The M1 wasn’t just a new chip—it was a statement. It delivered desktop-level performance on fanless laptops like the MacBook Air, upending expectations about what ARM-based architecture could achieve in mainstream computing.

Two years later, the M2 refined that formula. It brought better memory bandwidth, improved GPU performance, and support for higher-resolution displays. The 2022 iPad Pro was the first tablet to feature the M2, signaling Apple’s intent to position the iPad as a primary computer for more users. Still, many professionals held back, citing software limitations and the lack of certain pro-grade I/O features.

The M4 changes that calculus. Built on a 3nm process—Apple’s first chip to use it—the M4 packs more transistors into a smaller space, reducing heat and boosting efficiency. That’s critical for a device without active cooling. The architecture allows sustained performance that previous iPads couldn’t maintain, especially during video editing or 3D modeling.

Over the past four years, Apple has quietly rebuilt its entire hardware lineup around this silicon strategy. The transition wasn’t just about performance. It was about control. By designing its own chips, Apple can tightly integrate hardware and software, optimize for battery life, and build specialized components like the Neural Engine directly into the SoC. That integration is now central to its product identity.

Each generation has also expanded the scope of on-device intelligence. The M1 had a 16-core Neural Engine; the M2 offered modest improvements. The M4, however, accelerates machine learning tasks by up to 3x compared to the M2, according to Apple’s internal benchmarks. That enables real-time image analysis, voice processing, and language translation without relying on cloud servers. For users, that means faster, more private AI features. For developers, it opens new possibilities in app design.

What This Means For You

If you’re a developer, founder, or builder, the M4-powered iPad Pro isn’t just another gadget. It’s a signal of where Apple sees the future of computing: mobile, intelligent, and deeply integrated. Here’s how it might affect your work.

Scenario 1: Building AI-First Apps
The M4’s Neural Engine can process 38 trillion operations per second. That kind of power means you can run large language models locally. Imagine a note-taking app that summarizes meetings in real time, or a design tool that generates UI mockups from voice input—all without sending data to the cloud. Privacy becomes a selling point, not just a feature. Apps that once needed server infrastructure can now operate entirely on-device, reducing costs and complexity. You’ll also see faster inference times, which means smoother user experiences in apps that rely on image or speech recognition.

Scenario 2: Rethinking the Creative Workflow
Video editors, illustrators, and 3D artists are already using iPads in hybrid workflows. The M4 pushes that further. With support for external displays up to 6K via the upcoming Studio Display for iPad, color-accurate editing is now viable in a tablet form factor. Combine that with the Apple Pencil Pro’s hover detection and haptics, and you’ve got a precision tool that rivals traditional pen tablets. Founders building creative SaaS tools should consider how their software performs on iPadOS. Will your web app support freeform windowing? Can users connect external storage via USB4? These are no longer edge cases—they’re core use cases.

Scenario 3: Challenging the Laptop as the Default Work Machine
For startups and remote teams, device cost and manageability matter. The iPad Pro with M4 starts at $999, undercuts most MacBooks, and includes LTE options for always-on connectivity. If your team uses cloud-based tools—Figma, Notion, Google Workspace, linear.app—the iPad Pro might be enough. IT admins can deploy and manage these devices via MDM solutions just like iPhones. That simplicity could make iPads the default device for field teams, sales reps, or educators. Founders selling B2B software should test their platforms on iPadOS 18, especially with the new multitasking system. If your app doesn’t adapt well to split views or resizable windows, users will notice.

Technical Architecture: What’s Inside the M4

The M4 is more than a faster CPU. It’s a system-on-a-chip (SoC) designed for parallel processing and low-latency tasks. At its core are eight CPU cores—four performance cores and four efficiency cores—allowing the chip to handle intensive workloads while preserving battery during lighter tasks. The performance cores use wider instruction pipelines and larger caches than the M2, reducing bottlenecks in demanding applications.

The 10-core GPU supports hardware-accelerated ray tracing, a first for an iPad chip. That’s not just for games. Architects and engineers can render realistic lighting in 3D models on the go. Filmmakers can preview visual effects with accurate shadows and reflections. The GPU also includes dynamic caching, which allocates memory based on real-time needs, improving frame rates and reducing stutter.

Memory bandwidth has doubled compared to the M2, reaching 120GB/s. That may sound abstract, but it translates to real-world gains. Apps launch faster, large files load quicker, and multitasking feels smooth. The base model includes 8GB of unified memory, with options for 16GB and 32GB in the higher-end configurations. Storage starts at 128GB and goes up to 2TB, using faster NAND flash than previous models.

The Neural Engine is where the M4 truly diverges. It’s not just faster—it’s smarter. Apple has added matrix multiplication engines that accelerate transformer models, the kind used in modern AI. This means apps can run models like Whisper (speech-to-text) or Stable Diffusion (image generation) locally, without latency or data fees. Developers can access this through Apple’s Core ML framework, which now supports quantized models for even greater efficiency.

Power efficiency remains a hallmark. Despite the performance jump, the M4 consumes less power under load than the M2. Apple says the new iPad Pro delivers up to 12 hours of battery life during mixed use. That’s impressive for a device with an OLED display, which typically draws more power than LCDs. The engineering trade-offs here suggest Apple has optimized not just the chip, but the entire display pipeline, including brightness management and pixel refresh rates.

What Happens Next

The M4 in the iPad Pro is just the beginning. Apple typically rolls out its latest chip across multiple devices in the following months. We’re likely to see the M4 in the MacBook Air, 13-inch MacBook Pro, and eventually the Mac mini and iMac. Each iteration will push the boundaries of what’s possible in thin, fanless designs.

But key questions remain. Will iPadOS evolve fast enough to match the hardware? The new multitasking features in iPadOS 18 are a step forward, but the platform still lacks some pro features—like full external display support with independent workspaces or native terminal access. Developers have long asked for a real file system API, better automation tools, and support for multiple user accounts. Without those, the iPad will remain a secondary machine for many.

Another open question: How will developers adopt on-device AI? Core ML is powerful, but model optimization is still a hurdle. Large models require pruning, quantization, and testing across device tiers. Apple hasn’t yet provided cloud-to-edge model conversion tools, which means teams have to do that work themselves. That could slow adoption, especially at smaller startups.

And then there’s pricing. The iPad Pro with M4, Apple Pencil Pro, and Studio Display for iPad can easily exceed $2,000. That’s MacBook Pro territory. For Apple to truly replace laptops for a broader audience, it may need to bring M4-level performance to a lower-cost iPad model. The current iPad Air still uses the M1—a two-generation gap. Closing that could accelerate adoption in education and emerging markets.

Finally, what about competition? Qualcomm is pushing its Snapdragon X Elite chips as a Windows alternative to Apple Silicon, with strong AI performance and 5G integration. Microsoft is betting on AI PCs with Copilot+ features, requiring 40+ TOPS of NPU performance—a bar the M4 likely exceeds. But Windows on ARM still struggles with app compatibility. Apple’s ecosystem advantage remains strong, but it’s no longer unchallenged.

The M4-powered iPad Pro is the Most Capable tablet Apple has ever made. It’s not just a device. It’s a vision: computing that’s portable, intelligent, and personal. Whether that vision becomes mainstream depends on software, pricing, and how quickly the rest of the industry follows—or falls behind.
