M4 enables the breakthrough design and stunning display of the
new iPad Pro, while delivering a giant leap in performance
Apple® today announced M4, the latest chip delivering phenomenal
performance to the all-new iPad Pro®. Built using second-generation
3-nanometer technology, M4 is a system on a chip (SoC) that
advances the industry-leading power efficiency of Apple silicon and
enables the incredibly thin design of iPad Pro. It also features an
entirely new display engine to drive the stunning precision, color,
and brightness of the breakthrough Ultra Retina XDR™ display on
iPad Pro. A new CPU has up to 10 cores, while the new 10-core GPU
builds on the next-generation GPU architecture introduced in M3,
and brings Dynamic Caching, hardware-accelerated ray tracing, and
hardware-accelerated mesh shading to iPad® for the first time. M4
has Apple’s fastest Neural Engine ever, capable of up to 38
trillion operations per second, which is faster than the neural
processing unit of any AI PC today. Combined with faster memory
bandwidth, along with next-generation machine learning (ML)
accelerators in the CPU, and a high-performance GPU, M4 makes the
new iPad Pro an outrageously powerful device for artificial
intelligence.

“The new iPad Pro with M4 is a great example of how building
best-in-class custom silicon enables breakthrough products,” said
Johny Srouji, Apple’s senior vice president of Hardware
Technologies. “The power-efficient performance of M4, along with
its new display engine, makes the thin design and game-changing
display of iPad Pro possible, while fundamental improvements to the
CPU, GPU, Neural Engine, and memory system make M4 extremely well
suited for the latest applications leveraging AI. Altogether, this
new chip makes iPad Pro the most powerful device of its kind.”
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 Apple silicon. M4 also features an entirely new
display engine designed with pioneering technologies, enabling the
stunning precision, color accuracy, and brightness uniformity of
the Ultra Retina XDR display, a state-of-the-art display created by
combining the light of two OLED panels.
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 Apple innovation that allocates local memory
dynamically in hardware and in real time to dramatically increase
the average utilization of the GPU. This significantly increases
performance for the most demanding pro apps and games.
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 Apple silicon’s
industry-leading performance per watt. M4 can deliver the same
performance as M2 using just half the power. And compared with the
latest PC chip in a thin and light laptop, M4 can deliver the same
performance using just a fourth of the power.2
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.
Today, Apple is carbon neutral for global corporate operations,
and by 2030, plans to be carbon neutral across the entire
manufacturing supply chain and life cycle of every product.
Apple revolutionized personal technology with the introduction
of the Macintosh in 1984. Today, Apple leads the world in

found it.
1 Testing was conducted by Apple in March and April 2024. See
apple.com/ipad-pro for more information. 2 Testing was conducted by
Apple in March and April 2024 using preproduction 13-inch iPad Pro
(M4) units with a 10-core CPU and 16GB of RAM. Performance was
measured using select industry‑standard benchmarks. PC laptop chip
performance data is from testing ASUS Zenbook 14 OLED (UX3405MA)
with Core Ultra 7 155H and 32GB of RAM. Performance tests are
conducted using specific computer systems and reflect the
approximate performance of iPad Pro.
