Apple M4 (9-core CPU)

Name: Apple M4 (9-core CPU)
Brand: Apple
SKU: 76140

Manufacturer: Apple

The Apple M4, also referred to as the Apple M4 (9-core CPU), is a processor built on a 3 nm semiconductor process and intended for both laptop and desktop platforms. It incorporates integrated graphics and supports 64-bit computing, reflecting a design aimed at unified, general-purpose use across a range of devices.

On the performance side, the M4 operates with a mixed-core layout under big.LITTLE and HMP architectures, delivering clock speeds of 3 cores at 4.05 GHz and 6 cores at 2.75 GHz across its 9 threads. Memory support reaches up to 24 GB of DDR5 RAM running at 6400 MHz, with a maximum bandwidth of 120 GB/s. The chip does not support ECC memory but includes security features such as TrustZone and the NX bit. Its integrated GPU can drive up to 2 displays simultaneously.

Pros

Built on a 3 nm process with 28,000 million transistors, enabling a dense and efficient core architecture
Supports DDR5 memory at up to 6400 MHz with a peak bandwidth of 120 GB/s, facilitating fast data throughput
The 9-core CPU uses both big.LITTLE and HMP technologies, allowing all core types to handle threads simultaneously rather than switching sequentially
Compatible with both laptop and desktop platforms, offering deployment flexibility across different device types
Includes hardware-level security features — TrustZone and the NX bit — providing built-in protection against certain execution-based vulnerabilities
Integrated graphics support for up to 2 simultaneous displays without requiring additional hardware

Cons

Maximum memory capacity is capped at 24 GB, which may be limiting for memory-intensive workloads
ECC memory is not supported, reducing suitability for applications that require error-correcting memory
The integrated GPU is limited to 2 displays, restricting multi-monitor configurations beyond that count

Who is this for?

This chip is well-suited for users who need a processor capable of handling multithreaded workloads efficiently, thanks to its 9-core HMP-enabled design that keeps all core types active simultaneously. The 120 GB/s memory bandwidth and DDR5 support at 6400 MHz make it a solid fit for tasks that depend on rapid data movement, such as media processing or creative workflows. Its compatibility with both laptop and desktop platforms also makes it a practical choice for those who need the same architecture across different form factors, while the dual-display integrated graphics support suits users running a basic multi-monitor desktop setup without dedicated GPU hardware.

Who is this NOT for?

Users with workflows that demand large memory headroom will find the 24 GB maximum RAM ceiling restrictive, particularly for tasks such as large dataset processing or running multiple virtual machines simultaneously. The absence of ECC memory support makes this chip unsuitable for server environments, scientific computing, or any application where memory error correction is a baseline requirement. Additionally, those who need to drive more than two displays from integrated graphics will find the chip's two-display output limit insufficient for expanded multi-monitor configurations.

General info:

number of transistors	28000 million
Supports 64-bit	✓

The Apple M4 is designed for use in both laptop and desktop platforms, offering flexibility across different form factors. Built on a 3 nm semiconductor process, it integrates 28,000 million transistors within its architecture. The chip includes integrated graphics and fully supports 64-bit computing, making it capable of handling modern workloads across the devices it targets.

Performance:

CPU speed	3 x 4.05 & 6 x 2.75 GHz
CPU threads	9 threads
Uses big.LITTLE technology	✓
Uses HMP	✓

The Apple M4 features a 9-thread CPU configuration with a mixed-frequency layout, running 3 cores at 4.05 GHz and 6 cores at 2.75 GHz. It employs both big.LITTLE technology and Heterogeneous Multi-Processing (HMP), allowing the chip to assign tasks across cores of different performance levels simultaneously rather than switching between them exclusively.

Benchmarks:

Integrated graphics:

supported displays	2

The Apple M4 includes integrated graphics capable of supporting up to 2 displays simultaneously, allowing multi-monitor output without the need for a discrete GPU.

Memory:

RAM speed (max)	6400 MHz
maximum memory bandwidth	120 GB/s
DDR memory version	5
maximum memory amount	24GB
Supports ECC memory	✕

The Apple M4 supports DDR5 memory with a maximum capacity of 24 GB and a peak speed of 6400 MHz. It delivers a maximum memory bandwidth of 120 GB/s, enabling high data throughput between the CPU and memory. ECC memory is not supported by this chip.

Features:

Has TrustZone	✓
Has NX bit	✓

The Apple M4 includes two hardware security features: TrustZone, which creates an isolated secure execution environment at the hardware level, and the NX bit, which helps prevent certain classes of malicious code from executing in memory regions designated as non-executable.

Final Verdict

The Apple M4 (9-core CPU) is a well-defined chip built around a 3 nm architecture that balances core efficiency with data throughput, particularly through its 120 GB/s memory bandwidth and DDR5 support. Its HMP-enabled multi-core layout and cross-platform compatibility with both laptop and desktop devices give it a broad deployment range, while built-in security features like TrustZone and the NX bit add a layer of hardware-level protection without requiring additional components. Where it narrows its audience is in the 24 GB memory ceiling and the lack of ECC support, which place it outside the scope of server-grade or heavy compute environments. For users whose workflows align with its design — creative tasks, general productivity, and light multi-display setups — the M4 delivers a coherent and capable specification set that holds up well within its intended scope.
