Apple M4 Pro (14-core CPU / 20-core GPU)

Name: Apple M4 Pro (14-core CPU / 20-core GPU)
Brand: Apple
SKU: 8436

Manufacturer: Apple

Apple's M4 Pro, configured with a 14-core CPU and 20-core GPU, is a processor designed for both laptop and desktop platforms. Manufactured on a 3 nm process node with 28 billion transistors, it brings a refined level of silicon integration to its class. The chip employs big.LITTLE technology through a split-core arrangement — ten performance cores running at 4.05 GHz paired with four efficiency cores at 2.75 GHz — allowing workload distribution across 14 threads in total.

On the memory side, the M4 Pro supports up to 64 GB of DDR5 RAM at speeds reaching 6400 MHz, with a maximum memory bandwidth of 273 GB/s. Integrated graphics are included, with support for up to three simultaneous displays. The chip's Geekbench 6 scores stand at 3844 single-core and 22285 multi-core. Security-oriented features such as TrustZone and NX bit support are present, though ECC memory is not supported. 64-bit operation is fully supported across the architecture.

Pros

Manufactured on a 3 nm process with 28 billion transistors, reflecting a high level of chip density for its platform
The split-core design — ten cores at 4.05 GHz and four at 2.75 GHz — allows workload distribution across 14 threads using both big.LITTLE and HMP support
Maximum memory bandwidth of 273 GB/s ensures substantial data throughput for memory-intensive tasks
DDR5 support with speeds up to 6400 MHz and a 64 GB ceiling provides a wide operational range for demanding workloads
Integrated graphics can drive up to three displays simultaneously without requiring a discrete GPU
TrustZone and NX bit support add hardware-level security capabilities relevant to both laptop and desktop deployments

Cons

ECC memory is not supported, which limits reliability in error-sensitive or mission-critical computing environments
With only 14 CPU threads, highly parallelized workloads that benefit from a larger thread count may encounter a ceiling
Integrated graphics, while supporting three displays, may not satisfy workloads requiring dedicated GPU resources

Who is this for?

This chip is well-suited to users who need a processor capable of handling demanding multi-threaded workloads across both laptop and desktop form factors. The combination of DDR5 support, a 273 GB/s memory bandwidth ceiling, and up to 64 GB of RAM makes it a practical fit for tasks that rely heavily on fast memory access, such as video editing, data processing, or complex creative workflows. The ability to drive three displays simultaneously through integrated graphics also makes it a reasonable choice for multi-monitor productivity setups without the addition of a discrete GPU.

Who is this NOT for?

Users with requirements around error-sensitive or fault-critical computing will find this chip unsuitable, as it lacks ECC memory support — a feature typically expected in server, workstation, or scientific computing environments. Similarly, those running workloads that depend on a high dedicated GPU throughput may find the integrated graphics insufficient, since no discrete graphics specifications are present in the available data. Users who require a very high thread count for massively parallel processing tasks may also find the 14-thread ceiling a limiting factor.

The M4 Pro's CPU configuration consists of ten cores running at 4.05 GHz and four cores at 2.75 GHz, spread across 14 threads in total. This arrangement is made possible by big.LITTLE technology, which allows different core types to handle workloads according to their demands. The chip also employs Heterogeneous Multi-Processing (HMP), enabling all cores to operate simultaneously rather than switching between them exclusively.

Benchmarks:

Geekbench 6 result (multi)	22285
Geekbench 6 result (single)	3844

In Geekbench 6 testing, the M4 Pro records a single-core score of 3844 and a multi-core score of 22285, providing a measurable indication of how the chip handles both single-threaded tasks and workloads that draw on all available cores simultaneously.

Integrated graphics:

supported displays	3

The M4 Pro's integrated graphics support up to three displays simultaneously, allowing multi-monitor setups without the need for a discrete graphics card.

Memory:

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

The M4 Pro supports DDR5 memory with a maximum speed of 6400 MHz and can accommodate up to 64 GB of RAM. Its maximum memory bandwidth reaches 273 GB/s, enabling substantial data throughput between the processor and memory. ECC memory is not supported by this chip.

Features:

Has TrustZone	✓
Has NX bit	✓

The M4 Pro includes two hardware-level security features: TrustZone, which provides isolated execution environments for security-sensitive operations, and the NX bit, which helps prevent certain classes of malicious code from executing in memory regions designated for data.

Final Verdict

The Apple M4 Pro (14-core CPU / 20-core GPU) presents a well-rounded processor profile for users operating across laptop and desktop environments who place real demands on memory throughput and sustained multi-threaded performance. Its 3 nm fabrication, DDR5 memory support, and 273 GB/s memory bandwidth give it a technically coherent specification set for creative, productivity, and data-intensive workloads — further complemented by integrated multi-display support and hardware-level security features. Those with needs extending to ECC memory, high discrete GPU output, or extreme thread counts will find its scope somewhat constrained, but within its intended range, the M4 Pro offers a technically consistent and capable foundation for the platforms it targets.
