Chances are, you've heard about them already – at least if you follow tech news. The **M3** is Apple's third generation of silicon chips for its Macbooks and iPads. But why are people so excited about them?
Apple announced on October 30, 2023, that it will unveil its M3 series of system-on-chip (SoC) on November 7. The M3 lineup is said to be the most revolutionary chip design in the industry currently. Notably, this will be the first chip fabricated using a 3-nanometer process, marking a significant upgrade from the previous 5-nanometer SOC technology.
The new Apple M3 processor boasts an upgraded graphics processing unit (GPU), which should deliver significantly better performance than its predecessors for video editing and gaming. According to reports, the M3 is already spec-for-spec with Qualcomm's as-yet-unreleased Snapdragon Elite X.
Apple's products have regularly featured wow factors. This year is no exception. The company's new M-series SOCs promise much that is exciting.
The M3 series includes features such as dynamic caching, hardware-accelerated mesh shading, hardware-accelerated ray tracing, and an advanced media engine.
Last year's M2 chip series supported up to 96 GB of unified memory with a bandwidth of 400 GB/s. This year, the maximum has been raised to 128 GB, with the same bandwidth.
Dynamic Cache is a unique feature designed to replace traditional GPU memory allocation techniques. With conventional GPU architectures, available GPU memory is assigned to a single task. This is not always efficient, since much of the GPU's processing power goes unused.
With its pool, Apple allocates to each task only the memory it needs, and memory is shared among functions. All of this happens at the hardware level, boosting efficiency dramatically. The result is a transformed caching architecture.
The new GPUs in this lineup feature hardware-accelerated mesh shaders, which boost graphics performance for tasks like gaming geometry and complex visual scenes, as well as graphics-intensive applications.
This is great news for gamers and anyone else who needs lots of GPU power for tasks involving visual, real-time rendering.
In gaming, ray tracing is a significant factor, as it's a rendering technique that simulates how light interacts with objects in a scene. With Apple's new hardware-accelerated ray tracing,
It is not only more powerful; it is also 2.5 times faster than Apple's M1 chip series, enabling game developers to use its ray-tracing capabilities to create realistic shadows, reflections, and immersive gaming environments.
The new M3 series features a new hardware-accelerated advanced media engine that supports widely used video codecs such as HEVC, H.264, ProRes, and ProRes RAW. It also includes the industry's first media engine with AV1 decoding support, enabling more efficient and power-friendly streaming of services.
The M3 series features a new and improved Neural Engine that runs machine learning models up to twice as fast as before. The new Neural Engine is 60% faster than the M1 series.
It also enables faster AI and machine-learning environments without your data leaving your device, thus preserving your privacy.
As we can see, the Apple M3 series will have three different models: the M3, M3 Pro, and M3 Max. What are the differences between these three? Let's find out!

Whenever Apple introduces a new family of SOCs, you tend to see a variety of chip combinations available across different Macs. And that's what we're going to see with the M3 family as well.
14-inch Macbook Pro | M3, M3 Pro, M3 Max |
16-inch Macbook Pro | M3, M3 Pro, M3 Max |
iMac | M3 |
This outlines the chipsets available for different types of Mac, but you can configure your Mac with the number of cores you need.
With the M3 Pro, you get a combination of:
On an M3 Mac, you'd get this combination:
As of now, the M3 series chips are exclusive to the MacBook Pro and iMac. There are rumors that the Mac Pro and Mac Studio will be equipped with new M3 chips, but this has not been officially confirmed.
It's a video that helps them learn more about the MacBook Pro with an M3 chip.
We've seen the new features that the M3 chipsets bring, but how do they stack up against last year's M2 models? Let's find out.
There will be four versions of the M2: M2, M2 Pro, M2 Max, and M2 Ultra.
For this comparison against the M3, M3 Pro, and M3 Max, we'll retain the M2, M2 Pro, and M2 Max. Though the M2 Ultra is excluded, we'll put it aside since it's only relevant to the Mac Studio and Pro, making for a fairer comparison.
Specs | M2 | M3 |
Manufacturing Process Technology | 5nm | 3nm |
Transistor Count (Billions) | 20 | 25 |
CPU Core Count | 8 Cores (4 Performance + 4 Efficiency) | 8 Cores (4 Performance + 4 Efficiency) |
GPU Core Count | 8 Cores, 10 Cores | 10 Cores |
Neural Engine Core Count | 16 Cores | 16 Cores |
Memory Configurations | 8GB, 16GB, 24GB | 8GB, 16GB, 24GB |
Unified Memory Bandwidth | 100GB/s | 100GB/s |
Comparing M2 and M3, we see very little difference. The main differences lie in the number of transistors used and the manufacturing process.
Though the M3 Pro on paper looks like a downgrade, benchmark scores still favor the M3 Pro. The actual downgrade for the M3 Pro comes in the form of a reduced unified memory bandwidth speed from 200GB/s to 150GB/s. It's been reported that Apple used the same 192-bit memory bus as the M2 in the M3 Pro, rather than the updated 256-bit memory bus.
Finally, the M2 and M3 may turn out to be indistinguishable. But one lesson that Apple teaches us time and again is not to trust the raw scores, and that is certainly true for now.
The M3 series has some unique features that boost its performance in real life significantly, even though it might look weaker on paper.
The M3 features include dynamic caching, hardware-accelerated ray tracing, mesh shading, and a new neural engine. We also got a comparison with last year's lineup, which may require some clarification for many, given the similar – and in some cases lower – specs relative to the M2 series.
Still, the M3 has some revolutionary new features that make it well worth buying. Be sure to share this article on your social networks and discuss the M3 chip with your friends!
Now that you're familiar with everything about the M3 series, here are some important FAQs about the M3 chip that you should know:
Is the M3 better than the M2?
Yes, for example, the M3 chip lacks some of the new features we see in the new M3 series, like dynamic compute and the new ray-tracing architecture.
Which M3 MacBook Pro should I buy?
It depends on your needs; if you use your computer for routine tasks without heavy workloads, the base-model MacBook with the M3 chip will be fine. But if you do more demanding work, you should opt for a higher configuration.
3. How much faster is the M3 than its predecessor?
On paper, the M3 is similar to its predecessor. But in practice, it outperforms the M2, with reports suggesting that it is more than 15% faster overall.
What will be new in the Apple M3 chip?
Apple's M3 chips, based on TSMC's latest 3-nanometer process, will feature industry-firsts such as dynamic caching, ray tracing, and mesh shading.
