Apple has recently unveiled its new MacBook Pro models, featuring a redesigned chassis, a mini-LED display, and a range of ports that were missing from the previous generation. But the most impressive feature of the new laptops is the M3 chip family, which includes the M3, M3 Pro, and M3 Max processors. These chips are based on Apple’s own ARM architecture, and they promise to deliver a significant boost in speed, efficiency, and battery life compared to the Intel-based Macs.
We will review the new MacBook Pro and evaluate how the M3 chips perform in various tasks, such as web browsing, video editing, gaming, and machine learning. I will also compare the different models and configurations of the M3 chips, and help you decide which one is best for your needs. The M3 chip family is composed of three variants: the M3, M3 Pro, and M3 Max. They all share some common features, such as:
A 5-nanometer process technology, which allows for more transistors and lower power consumption. An integrated system-on-a-chip (SoC) design, which eliminates the need for separate components such as RAM, GPU, and I/O controllers. A unified memory architecture (UMA), which enables faster data transfer between the CPU and GPU cores. A 16-core Neural Engine, which accelerates machine learning tasks such as image recognition and natural language processing.

However, there are also some differences between the three chips, mainly in terms of core count, cache size, memory bandwidth, and GPU performance. Here is a summary of the main specifications of each chip:
| Chip | CPU cores | GPU cores | Cache size | Memory bandwidth | Max power |
|——|———–|———–|————|——————|———–|
| M3 | 8 (4 performance + 4 efficiency) | 8 | 12 MB | 200 GB/s | 35 W |
| M3 Pro | 10 (6 performance + 4 efficiency) | 14 | 16 MB | 200 GB/s | 45 W |
| M3 Max | 10 (6 performance + 4 efficiency) | 32 | 32 MB | 400 GB/s | 60 W |
As you can see, the M3 Pro and M3 Max have more CPU and GPU cores than the M3, which means they can handle more demanding workloads. The M3 Max also has twice the cache size and memory bandwidth of the other two chips, which means it can access data faster and support more RAM. The trade-off is that the M3 Pro and M3 Max consume more power than the M3, which may affect battery life and thermal management.
The main difference between the M3 and Intel chip families is that the M3 chips are optimized for Apple’s software and hardware ecosystem, while the Intel chips are designed for a wider range of devices and operating systems. This means that the M3 chips can take advantage of features such as Metal (Apple’s graphics framework), Core ML (Apple’s machine learning framework), and Rosetta 2 (Apple’s emulation software for running Intel-based apps). The Intel chips, however, may have better compatibility with some third-party apps and peripherals that are not optimized for Apple’s platform.
The new MacBook Pro: How does it look and feel?
The new MacBook Pro models come in two sizes: 14-inch and 16-inch. They both have a similar design language, with flat edges, rounded corners, and an aluminum body. The most noticeable change from the previous generation is the display, which uses a mini-LED technology called Liquid Retina XDR.
This display offers higher brightness, contrast, color accuracy, and resolution than the standard LCD screens. The 14-inch model has a resolution of 3024 x 1964 pixels, while the 16-inch model has a resolution of 3456 x 2234 pixels. Both models support ProMotion technology, which adjusts the refresh rate up to 120 Hz depending on the content.
Another major change is the return of some ports that were absent from the previous generation. The new MacBook Pro models have three Thunderbolt 4 ports (two on the left side and one on the right side), an HDMI port (on the right side), an SD card slot (on the right side), and a MagSafe 3 port (on the left side).
The MagSafe 3 port is used for charging the laptop with a magnetic connector that can detach easily if someone trips over the cable. The Thunderbolt 4 ports support data transfer up to 40 Gbps, as well as charging and video output. The HDMI port supports up to 4K resolution at 60 Hz or up to 8K resolution at 30 Hz.
How the M3 chips outperform the Intel chips
Apple’s M3 chips are the latest generation of its custom-designed processors that power its MacBooks, iPads, and iPhones. These chips are based on the ARM architecture, which is different from the x86 architecture used by Intel and AMD. The M3 chips offer several advantages over the Intel chips, such as:
Higher performance: The M3 chips have more cores, higher clock speeds, and better integrated graphics than the Intel chips. They also have a unified memory architecture, which means that the CPU and GPU share the same memory pool, reducing latency and increasing bandwidth. The M3 chips can run both native ARM apps and x86 apps through emulation, with minimal performance loss. According to Apple, the M3 chips can deliver up to 2x faster performance than the Intel Core i7 chips in some tasks.
Lower power consumption: The M3 chips are more energy-efficient than the Intel chips, thanks to their 5-nanometer process technology and their heterogeneous design. The M3 chips have a mix of high-performance and high-efficiency cores, which can switch between different tasks depending on the workload. The M3 chips also have a neural engine, which can handle machine learning tasks with lower power consumption. According to Apple, the M3 chips can offer up to 21 hours of battery life on a single charge for some models.
Better security: The M3 chips have a secure enclave, which is a dedicated hardware component that stores sensitive data such as passwords, encryption keys, and biometric information. The secure enclave is isolated from the rest of the system and can only be accessed by authorized apps. The M3 chips also have a hardware-based encryption engine, which can encrypt and decrypt data without affecting performance. The M3 chips also support features such as Touch ID, Face ID, and Apple Pay, which enhance user security and convenience.
