Apple Unveils M4 Pro and M4 Max Chips
Apple just dropped its new M4 Pro and M4 Max SoCs, built on a second-gen 3nm process. The top-end M4 Max packs a 16-core CPU, a 40-core GPU, and an upgraded 16-core Neural Engine specifically for advanced on-device AI and ML workloads. These chips are already shipping in the latest MacBook Pros and iMacs.
The M4 Pro and M4 Max chips are the first in their class for Mac to reportedly use the ARMv9 instruction set, a notable architectural evolution from previous generations. This foundation, combined with TSMC's second-generation 3nm process, allows for significant performance leaps; the M4 Max CPU is up to 2.2 times faster than the M1 Max. For graphics-intensive development and testing, Geekbench 6 Metal scores show the M4 Pro is up to 40% faster than its M3 Pro predecessor. The top-tier 40-core GPU in the M4 Max also introduces a ray-tracing engine that is twice as fast as the one in the M3 family, directly benefiting developers working on 3D rendering or AAA gaming titles. A key enhancement for AI development is the updated Neural Engine, capable of 38 trillion operations per second (TOPS). This provides a substantial performance boost for on-device machine learning, allowing developers to interact with and run large language models with nearly 200 billion parameters directly on the machine. This raw power translates to tangible workflow improvements, with tasks like compiling large projects in Xcode seeing a noticeable speed increase. The M4 Max also doubles the number of ProRes accelerators and video encode engines, a critical upgrade for developers working with high-resolution video APIs. Memory bandwidth sees a major increase, with the M4 Pro offering up to 273 GB/s and the M4 Max pushing an impressive 546 GB/s. This allows for smoother handling of large datasets and more complex multitasking scenarios, such as running multiple virtual devices in Android Studio and Xcode simultaneously with minimal performance impact. For the first time on Mac, these chips enable Thunderbolt 5, which supports data transfer speeds of up to 120 Gb/s. This improves connectivity with high-speed external storage and peripherals, streamlining development workflows that rely on large external assets. On the ecosystem front, the hardware's deep integration with macOS unlocks frameworks like MatterSupport. This allows developers to create apps that can seamlessly pair with and control smart home accessories, leveraging the secure, on-device processing power of the M4 series for home automation tasks.
