M5 Pro and M5 Max are surprisingly big departures from older Apple Silicon

In a significant update during the latest MacBook Pro reveal, Apple introduced the M5 Pro and M5 Max chips, marking a striking evolution in their silicon technology. Traditionally, the Pro and Max versions build on the foundational design of the base chip, enhancing it with additional CPU and GPU cores, alongside increased memory bandwidth. However, the new M5 series takes a remarkable turn from its predecessors, showcasing a fresh architecture and innovative packaging. The real-world performance implications of these changes remain to be seen until users can get their hands on the hardware. Nevertheless, the technical specifications shed light on the advancements within the M5 family compared to earlier generations of Apple Silicon. Apple has highlighted that the M5 Pro and M5 Max feature an entirely new "Fusion Architecture" that integrates two silicon chiplets into a single processing unit. While Apple has previously employed similar techniques, it was primarily to merge two Max chips into an Ultra model. Here, the design diverges significantly; the M5 Pro is not merely two M5 chips fused together. Instead, one chiplet is dedicated to CPU functions and most input/output tasks, while the second focuses largely on graphics, with both components manufactured using TSMC's cutting-edge 3nm process. The foundational silicon die remains consistent across both the M5 Pro and M5 Max variants. This includes an impressive 18-core CPU, a 16-core Neural Engine, and the necessary controllers for SSD, Thunderbolt ports, and display outputs.
