Apple M4 GPU (8-core) vs Apple M1 GPU (8-core): Full Comparison
Introduction
Comparing the graphics processing units (GPUs) from Apple’s M1 and M4 chips provides a clear view of the company’s rapid advancement in silicon design. While both are 8-core integrated GPUs designed for efficiency and performance in Apple’s ecosystem, the underlying technologies and capabilities are separated by several years of innovation. This analysis breaks down the key differences in architecture, performance, features, and efficiency to help understand the evolution from M1 to M4 graphics.
Architecture and Fabrication
The fundamental building blocks of these GPUs are built on different technological foundations, which dictates their potential performance and efficiency.
- Apple M1 GPU: Based on a GPU architecture that was a significant step for Apple’s first-generation Apple Silicon. It was fabricated using a 5-nanometer process, which was leading-edge at its introduction.
- Apple M4 GPU: Features a next-generation GPU architecture that builds upon the learnings from the M2 and M3 generations. It is fabricated on an enhanced second-generation 3-nanometer process, allowing for a higher density of transistors and typically greater power efficiency.
The move to a 3nm process is a key differentiator, enabling more complex circuitry and performance enhancements within a similar or smaller power envelope.
Performance and Speed
In terms of raw graphics throughput, the difference between the two GPUs is generally substantial.
- Apple M1 GPU (8-core): Delivered excellent performance for its time, capably handling tasks like photo editing, video playback, and moderate gaming. It set a new standard for integrated graphics in thin-and-light devices.
- Apple M4 GPU (8-core): Offers a significant performance uplift. Apple has stated it provides up to 4x the performance of the M1 in certain pro-rendering applications. In more general terms, users can expect markedly higher frame rates in games, faster video effects rendering, and smoother performance in graphics-intensive creative applications.
The performance gap widens considerably in workloads that can leverage the M4’s new hardware-accelerated features.
Features and Capabilities
This is one of the most distinct areas of separation, with the M4 GPU introducing modern rendering technologies.
- Hardware-Accelerated Ray Tracing: This is a flagship feature of the M4 GPU that is absent in the M1. Ray tracing simulates the physical behavior of light to create vastly more realistic lighting, shadows, and reflections in supported games and 3D applications.
- Mesh Shading: Another M4-exclusive feature, mesh shading allows for more efficient rendering of complex geometry, improving performance and visual detail in advanced 3D environments.
- Dynamic Caching: A feature introduced with the M3 family and carried into the M4, it allocates the use of local memory in real time. This contrasts with the static memory allocation of the M1 GPU, leading to typically improved GPU utilization and efficiency for various tasks.
Efficiency and Media Engine
Both GPUs are part of a system-on-a-chip (SoC) designed for efficiency, but the M4 holds advantages.
- Power Efficiency: Thanks to the 3nm process and architectural refinements, the M4 GPU can deliver higher performance than the M1 at a similar power level, or similar performance at a lower power draw. This can contribute to longer battery life in portable devices under comparable workloads.
- Media Engine: While both chips have dedicated media engines for video encode/decode, the M4’s is more advanced. It adds support for hardware-accelerated H.264, HEVC, and AV1 decode, with AV1 support being a notable addition for efficient streaming video playback that the M1 lacks.

Frequently Asked Questions (FAQ)
What is the biggest difference between the M4 GPU and the M1 GPU?
The most significant differences are the introduction of hardware-accelerated ray tracing and mesh shading in the M4 GPU, features which are not present in the M1. These enable a new level of graphical fidelity and performance in supported applications.
Is the Apple M4 GPU better for gaming?
Yes, generally. The Apple M4 GPU offers substantially higher graphics performance and supports modern gaming technologies like ray tracing. This typically results in higher frame rates and more detailed visuals in games that can leverage the new hardware.
Does the M1 GPU support AV1 video decoding?
No, the M1’s media engine does not include hardware-accelerated AV1 decode. This feature was introduced later and is supported by the M4 GPU, allowing for more power-efficient playback of AV1-encoded streaming video.
Can the M1 GPU handle professional video editing?
Yes, the M1 GPU is capable of handling professional video editing, especially with optimized applications like Final Cut Pro. However, the M4 GPU will perform these tasks significantly faster and can handle more complex effects and higher-resolution timelines more smoothly.
Final Thoughts
The comparison between the 8-core GPUs in the Apple M1 and M4 chips illustrates a clear trajectory of rapid improvement. The M1 GPU was a groundbreaking integrated solution that redefined expectations for thin devices. The M4 GPU builds upon that foundation with a more advanced manufacturing process, a new architecture supporting cutting-edge rendering techniques, and substantially higher performance. The choice between systems using these GPUs often comes down to the specific demands of the user’s workflow—whether the tasks require the latest hardware-accelerated features and maximum speed offered by the M4, or if the capable and proven performance of the M1 remains sufficient.
