Apple introduces M4 chip - Seite 2

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.
