M4 is a system on a chip (SoC) that advances the industry-leading power-efficient performance of
“The new iPad Pro with M4 is a great example of how building best-in-class custom silicon enables breakthrough products,” said
New Technologies Enabling the New iPad Pro
Delivering a giant leap in performance over the previous iPad Pro with M2, M4 consists of 28 billion transistors built using a second-generation 3-nanometer technology that further advances the power efficiency of
New 10-core CPU
M4 has a new up-to-10-core CPU consisting of up to four performance cores and now six efficiency cores. The next-generation cores feature improved branch prediction, with wider decode and execution engines for the performance cores, and a deeper execution engine for the efficiency cores. And both types of cores also feature enhanced, next-generation ML accelerators.
M4 delivers up to 1.5x faster CPU performance over the powerful M2 in the previous iPad Pro.1 Whether working with complex orchestral music files in Logic Pro® or adding highly demanding effects to 4K video in LumaFusion, M4 boosts performance across pro workflows.
GPU Brings New Capabilities to iPad Pro
The new 10-core GPU of M4 builds upon the next-generation graphics architecture of the M3 family of chips. It features Dynamic Caching, an
Hardware-accelerated ray tracing comes to iPad for the first time, and enables even more realistic shadows and reflections in games and other graphically rich experiences. Hardware-accelerated mesh shading is also built into the GPU, and delivers greater capability and efficiency in geometry processing, enabling more visually complex scenes in games and graphics-intensive apps. Pro rendering performance in apps like Octane gets a huge boost with M4, and is now up to four times faster than on M2.1 With these improvements to the CPU and GPU, M4 maintains
The Most Powerful Neural Engine Ever
M4 has a blazing-fast Neural Engine — an IP block in the chip dedicated to the acceleration of AI workloads. This is Apple’s most powerful Neural Engine ever, capable of an astounding 38 trillion operations per second — a breathtaking 60x faster than the first Neural Engine in A11 Bionic. Together with next-generation ML accelerators in the CPU, the high-performance GPU, and higher-bandwidth unified memory, the Neural Engine makes M4 an outrageously powerful chip for AI. And with AI features in iPadOS® like Live Captions for real-time audio captions, and Visual Look Up, which identifies objects in video and photos, the new iPad Pro allows users to accomplish amazing AI tasks quickly and on device.
iPad Pro with M4 can easily isolate a subject from its background throughout a 4K video in Final Cut Pro® with just a tap, and can automatically create musical notation in real time in StaffPad by simply listening to someone play the piano. And inference workloads can be done efficiently and privately while minimizing the impact on app memory, app responsiveness, and battery life. The Neural Engine in M4 is Apple’s most capable yet, and is more powerful than any neural processing unit in any AI PC today.
Advanced Media Engine for Smooth, Efficient Streaming
The Media Engine of M4 is the most advanced to come to iPad. In addition to supporting the most popular video codecs, like H.264, HEVC, and ProRes®, it brings hardware acceleration for AV1 to iPad for the first time. This provides more power-efficient playback of high-resolution video experiences from streaming services.
Better for the Environment
The power-efficient performance of M4 helps the all-new iPad Pro meet Apple’s high standards for energy efficiency and deliver all-day battery life. This results in less time needing to be plugged in and less energy consumed over its lifetime.
