The Multi-Chiplet Approach

The multi-chiplet module (MCM) design is not entirely new to the graphics segment, but its application in consumer GPUs has been limited due to technical challenges. AMD's approach involves using a 'Smart Switch' to bridge communications between compute chiplets and memory controllers, similar to AMD's Infinity Fabric but scaled down for consumer GPUs 1

Overcoming Latency Challenges

One of the primary hurdles in implementing a chiplet design for gaming GPUs has been increased latency. AMD's patent proposes a solution that optimizes memory access by comparing whether a graphics task requires task migration or data replication, with decision latency on a nanosecond scale 2

Architectural Innovations

The proposed design includes:

1. Graphics Compute Dies (GCDs) with L1 and L2 caches
2. An extra shared L3 cache (or stacked SRAM) accessible through the smart switch
3. Stacked DRAM as a foundation for the MCM-based design

This architecture aims to reduce the need for global memory access and act as a shared staging zone between chiplets, similar to AMD's 3D V-Cache technology 1
