Apple M4 Pro (12-core CPU / 16-core GPU)

Name: Apple M4 Pro (12-core CPU / 16-core GPU)
Brand: Apple
SKU: 3538

Manufacturer: Apple

Apple's M4 Pro with a 12-core CPU and 16-core GPU is a processor designed for both laptop and desktop use, built on a 3 nm semiconductor process with 28 billion transistors. It supports 64-bit operation and incorporates big.LITTLE technology alongside Heterogeneous Multi-Processing to balance workload distribution across its core configurations.

On the performance side, the chip runs eight cores at 4.05 GHz and four cores at 2.75 GHz across 12 threads, with a 2 MB L2 cache and a thermal design power of 40W. Memory support extends to 64GB of DDR5 at up to 6400 MHz with a maximum bandwidth of 273 GB/s, while the integrated graphics can drive up to two displays. Security features include TrustZone and NX bit support, and Geekbench 6 results show a multi-core score of 20,164 and a single-core score of 3,843.

Pros

Built on a 3 nm process with 28 billion transistors, pointing to a compact and densely packed silicon design
Supports DDR5 memory at up to 6400 MHz with a maximum bandwidth of 273 GB/s, enabling high-throughput data movement
Can address up to 64 GB of RAM, accommodating memory-intensive workloads
Combines big.LITTLE technology with HMP, allowing workload distribution across performance and efficiency cores
Includes both TrustZone and NX bit support, providing two distinct layers of hardware-level security
Designed for both laptop and desktop deployment, offering flexibility across form factors

Cons

ECC memory is not supported, limiting its suitability for environments where data integrity under fault conditions is a priority
L2 cache is limited to 2 MB, which is relatively modest given the 12-core configuration
Integrated graphics support is capped at two displays, restricting multi-monitor setups beyond that count
A 40W TDP may present thermal management challenges in tightly constrained chassis designs

Who is this for?

This chip is well-matched for users who need to run memory-intensive and multi-threaded workloads across both laptop and desktop platforms, given its 64 GB DDR5 memory ceiling, 273 GB/s bandwidth, and 12-thread configuration. The combination of big.LITTLE technology and HMP makes it a reasonable fit for workflows that mix sustained heavy processing with lighter background tasks. Its inclusion of TrustZone and NX bit also makes it appropriate for environments where hardware-level security is a practical consideration rather than an afterthought.

Who is this NOT for?

Users who require ECC memory support — such as those running workloads where data integrity under hardware fault conditions is critical — will find this chip unsuitable, as that capability is absent. The integrated GPU's limit of two simultaneous displays makes it a poor fit for multi-monitor setups exceeding that count, and the 2 MB L2 cache may constrain throughput in cache-sensitive workloads at scale. Additionally, the 40W TDP could pose challenges in thermally constrained enclosures where sustained heat dissipation is difficult to maintain.

General info:

Type	Laptop, Desktop
Has integrated graphics	✓
Thermal Design Power (TDP)	40W
semiconductor size	3 nm
number of transistors	28000 million
Supports 64-bit	✓

The Apple M4 Pro (12-core CPU / 16-core GPU) is designed for both laptop and desktop use and features integrated graphics alongside full 64-bit support. Built on a 3 nm semiconductor process, it packs 28 billion transistors into its design, reflecting a high degree of circuit density. The chip carries a Thermal Design Power of 40W, which defines its heat output envelope across the platforms it targets.

Performance:

CPU speed	8 x 4.05 & 4 x 2.75 GHz
CPU threads	12 threads
L2 cache	2 MB
Uses big.LITTLE technology	✓
Uses HMP	✓

The processor operates across 12 threads, with eight cores running at 4.05 GHz and four cores at 2.75 GHz, reflecting a split-frequency design suited to varied workload demands. It employs both big.LITTLE technology and Heterogeneous Multi-Processing (HMP), allowing the chip to assign tasks across core types based on processing requirements rather than treating all cores as equivalent. A 2 MB L2 cache supports data access closer to the CPU, helping to reduce latency during active processing.

Benchmarks:

Geekbench 6 result (multi)	20164
Geekbench 6 result (single)	3843

In Geekbench 6 testing, the chip recorded a multi-core score of 20,164 and a single-core score of 3,843, providing a standardized reference point for evaluating its processing output across both parallel and sequential workloads.

Integrated graphics:

supported displays	2

The integrated graphics solution supports a maximum of 2 displays simultaneously, defining the multi-monitor capability available through the chip's built-in GPU.

Memory:

RAM speed (max)	6400 MHz
maximum memory bandwidth	273 GB/s
DDR memory version	5
maximum memory amount	64GB
Supports ECC memory	✕

The chip supports DDR5 memory at speeds of up to 6400 MHz, with a maximum capacity of 64GB and a peak memory bandwidth of 273 GB/s. These figures reflect the upper bounds of the chip's memory subsystem under its rated configuration. It is worth noting that ECC memory is not supported, meaning error-correcting memory configurations are not available on this platform.

Features:

Has TrustZone	✓
Has NX bit	✓

The chip includes two hardware security features: TrustZone, which provides a hardware-level isolated execution environment, 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 Pro (12-core CPU / 16-core GPU) is a well-rounded chip that brings together a dense 3 nm silicon design, a capable 12-thread core configuration, and 273 GB/s of memory bandwidth into a package that spans both laptop and desktop use cases. Its DDR5 memory support, hardware security features, and HMP-driven workload flexibility make it a credible option for users with demanding, mixed-use computing needs. That said, the absence of ECC support and the two-display ceiling on the integrated GPU do mark clear boundaries around its suitability. Taken as a whole, the M4 Pro occupies a well-defined position as a capable processor for professional and prosumer workflows, provided those workflows fall within the boundaries its specifications define.
