M-Series Madness: Exploring Apple's New Chipsets and the Tradeoffs They Bring



Apple’s introduction of its M-series chipsets marked a significant shift in the company’s hardware strategy and paved the way for enhanced performance and efficiency in its lineup of laptops. With the unveiling of the M3 Pro and M3 Max chipsets, the complexity of the SKU options has become apparent. This article aims to delve into some of the key observations and tradeoffs associated with these new chipsets.

Memory Bandwidth and Core Configurations:

One noticeable change in the M3 Pro chipset compared to its predecessor, the M2 Pro, is the reduction in memory bandwidth from 200GB/s to 150GB/s. Additionally, the M3 Max boasts a higher memory bandwidth of 400GB/s. These variations in memory bandwidth could have implications on performance, and it remains to be seen how this impacts real-world usage.

Interestingly, while the M3 Pro loses the option for an 8TB SSD, it features more E-cores (6) compared to the M3 Max, which has 4 E-cores. This departure from Intel’s approach, where higher-specced parts typically include more cores, highlights Apple’s focus on pushing performance within a specific power envelope.

The Nuances of Performance and Efficiency:

Apple’s decision to design its own chipsets stems from a desire to deliver both performance and efficiency. While some may argue that an A-series chip would have sufficed, Apple opted for the M-series to achieve higher performance while maintaining a restricted power budget. This approach allows for improved performance without compromising efficiency, addressing the needs and expectations of its user base.

Anonymous Usage Data and Performance Optimization:

To further understand user behavior and optimize performance, Apple collects anonymous usage data by default across all its operating systems. This data collection provides insight into the utilization of performance cores, memory bandwidth, and other crucial metrics. By harnessing this information, Apple can make informed decisions about core configurations and understand user preferences.

Considering Future Upgrades:

Apple’s marketing approach when comparing the M3 Pro to its predecessor, the M1 Pro, provides an interesting perspective. By comparing the M3 Pro to the M1 Pro rather than the M2 Pro, Apple acknowledges that most M2 users are unlikely to upgrade to the M3. This strategy is essential as the majority of Mac users tend to wait several years before upgrading their devices.

Balancing Performance, Reliability, and Upgradability:

The issue of upgradability has been a topic of debate regarding Apple’s laptops. While slotted RAM and expandable storage would offer more flexibility, the design choices made by Apple prioritize thinness and tightly packed chassis. Additionally, the move away from slotted RAM can be attributed to architectural considerations, where the CPU, GPU, and RAM are integrated on a single chip, enabling zero copy operations.

Considering Overall Sustainability:

Apple’s commitment to environmental sustainability extends beyond just creating long-lasting machines. It also includes efforts to ensure sustained software support for its devices. However, the longevity of hardware often surpasses the software support Apple provides, creating a disconnect that can be addressed through continued software updates.


As Apple’s M-series chipsets become increasingly complex, it is crucial to analyze and understand the tradeoffs and design choices associated with these advancements. From variations in memory bandwidth to the balance between performance and efficiency, Apple’s focus on pushing the boundaries of its hardware aligns with the needs of its user base. By carefully considering user data, performance optimization, and sustainability, Apple aims to deliver cutting-edge technology while minimizing its environmental impact.
