Apple’s Shift to Chiplet Design with M5 Pro & M5 Max: Will Qualcomm Follow Suit?

Apple’s upcoming M5 Pro and M5 Max processors are anticipated to feature a groundbreaking design with separate CPU and GPU components, made possible through TSMC’s innovative Small Outline Integrated Circuit (SoIC) packaging technology. This shift toward chiplet architecture not only aims to enhance performance on Apple’s portable Macs but also holds the potential for decreased manufacturing costs due to improved yields. However, Qualcomm has yet to embrace this refined architecture. In the following sections, we will explore several reasons why this is the case, while also arguing that a transition to chiplet design may ultimately be necessary for Qualcomm.

The Need for Qualcomm to Embrace Chiplet Design

The increasing complexity and physical dimensions of semiconductor chips have prompted companies like Apple to adopt chiplet designs. Both AMD and Intel’s Panther Lake series have already made strides in this direction. In contrast, Qualcomm’s Snapdragon X2 Elite Extreme and Snapdragon X2 Elite currently reflect a more traditional approach, leaving room for speculation regarding the company’s future strategies.

One significant factor is that Qualcomm is still in the early stages of developing ARM-based SoCs for laptops, with only its second generation now in production. Transitioning to a chiplet architecture necessitates extensive research and development, coupled with advanced engineering capabilities. Discussions emerging on online forums suggest a considerable amount of trial and error will be necessary, indicating that Qualcomm could require several years before it can introduce a Snapdragon product designed around chiplet technology.

However, if Qualcomm plans to launch the Snapdragon X3 Elite Extreme, they must act swiftly; otherwise, they may find themselves trailing behind competitors for an entire generation.

Challenges of Power Requirements in Chiplet Architecture

The Snapdragon X2 Elite Extreme has been known to consume over 100W of power under unlimited operational conditions. Additionally, a chiplet design necessitates increased energy consumption when chips communicate with one another. This aspect may lead Qualcomm to steer clear of chiplet architecture, as they might prioritize thermal efficiency. Implementing such a design would likely require partners to redesign cooling solutions, potentially resulting in bulkier and heavier notebook models.

This raises the question: If chiplet designs pose temperature challenges, why is Apple moving forward with this architecture for the M5 Pro and M5 Max? Apple’s expertise in architectural refinement and efficiency uniquely positions them to create powerful SoCs that maintain low power consumption, culminating in impressive battery life for their portable Macs.

If the M5 Pro and M5 Max utilize chiplet technology, this indicates that Apple has adeptly addressed thermal management concerns. Evidence of their success can be seen in the A19 Pro chipset; its efficiency cores achieve up to a 29% increase in performance without drawing additional power.

Performance Benchmarks Highlighting Qualcomm’s Limitations

Recent evaluations of the Snapdragon X2 Elite reveal impressive gains in CPU performance, outperforming the Apple M5 in many benchmarks. However, the chipset struggles in gaming scenarios, where it shows vulnerabilities. While the Snapdragon X2 Elite represents a significant upgrade over previous models, the M5 exhibits a level of graphic performance that indicates Qualcomm’s integrated GPU currently limits its capabilities.

In contrast, Intel’s Core Ultra X9 388H showcases robust graphics performance resulting from its newer architecture, signaling a direction Qualcomm must pursue to remain competitive in this fast-evolving market.
