The Future of Megalithic Dies
In recent times, the concept of megalithic dies has gained significant attention in the world of silicon. This emergence has sparked debates and discussions regarding the future of silicon and the potential of megalithic dies in solving common industry problems. In this article, we will explore the pros and cons of megalithic dies, comparing them to stacking techniques and examining their niche applications.
2.1 Stacking vs Megalithic Dies
Both stacking techniques and megalithic dies aim to solve similar problems - reducing latency and minimizing wasted energy. Stacking involves layering multiple chips on top of each other, allowing for efficient data transfer within a compact space. On the other HAND, megalithic dies consolidate multiple components onto a single, larger die. While both approaches strive for the same goal, the debate arises when considering which method is more effective.
Stacking chips has gained popularity among companies like Intel and AMD, with architectures like Foveros and Zen utilizing 3D stacking to optimize performance and efficiency. However, proponents of megalithic dies argue that consolidating components onto a larger die can achieve similar results. Despite the arguments, large die sizes may not be practical or efficient for most use cases, making megalithic dies more suitable for niche applications.
2.2 The Niche Use of Megalithic Dies
Megalithic dies, such as Sarah Bris's impressive 46,000 millimeters squared piece of silicon, may have a future in specific areas like ASICs and FPGAs. These specialized components require a significant amount of cache, memory, and other features, making megalithic dies an appealing option. However, the adoption of megalithic dies is likely to remain niche, as the majority of silicon production will continue to favor stacking techniques and chiplets.
While the potential of megalithic dies is intriguing, the future remains uncertain with blurry prospects. Despite claims that customer workloads are currently running on these impressive dies, the actual release and clock speeds are still undisclosed. As the industry evolves, it is essential to keep an eye on the developments surrounding megalithic dies to gain a deeper understanding of their true potential.
3. The Upheaval of Performance Increases
As the industry progresses towards architectures built around 3D stacking and chiplets, we can expect significant performance increases in the near future. Currently, the focus is on the first wave of chiplets, which serve as proof of concepts for utilizing 3D stacking. Companies like AMD and Intel are splitting I/O and cores, resulting in cost savings and improved performance.
3.1 The First Wave of Chiclets
The initial wave of chiplets primarily focuses on simplistic implementations, such as separating I/O from cores or combining powerful cores with smaller, more affordable ones. While these advancements are noteworthy, the real performance gains will come when architectures are purpose-built for 3D stacking.
3.2 Building Architectures around 3D Stacking
The next wave, represented by Zen 4, will mark a significant step forward in fully utilizing 3D stacking and chiplet techniques. TSMC's presentation suggests the potential for a 2,000x performance increase with the right application of stacking techniques. Even with more modest workloads, a 4 to 10x performance boost is achievable. This shift towards building architectures entirely around 3D stacking promises revolutionary advancements.
3.3 The Revolutionary Potential of Zen 4
Zen 4, designed from the ground up with 3D stacking in mind, has the potential to revolutionize the industry. By incorporating additional chiplets, such as HBM (High Bandwidth Memory), and further optimizing core distribution, Zen 4 can exhibit doubled performance or more. These improvements offer remarkable efficiency gains and pave the way for future advancements.
3.4 The Fully Realized Phase of 3D Stacked Architecture
Looking ahead, the progress of 3D stacking and chiplets will continue to evolve. The full realization of their potential is expected in the next waves, particularly with Zen 5 or Zen 6 on a 7-nanometer node by 2022-2023. The bugs and limitations will be ironed out, resulting in a newfound level of performance previously unimaginable. These advancements signify a departure from the reliance on Moore's Law and open up new possibilities for the industry.
4. Solving Thermal Limitations and Cooling Issues
While advancements in performance are exciting, the issue of thermal limitations and cooling remains a challenge. However, there are potential solutions on the horizon that can address these concerns.
4.1 3D Stacking and Cooling Solutions
In the future, it may be possible to integrate cooling solutions directly into 3D stacked architectures. For instance, the idea of 3D printing copper cooling pipes through the different stacks has been discussed. Although this solution is further down the line, it holds promise for efficient heat dissipation and improved cooling capabilities. Resolving these thermal challenges will further enhance the potential of megalithic dies and 3D stacked architectures.
4.2 The Future of Silicon with Graphene and Nanotubes
Looking beyond the next decade, the integration of graphene and nanotubes alongside silicon holds the possibility of achieving even greater performance gains. By combining these materials in a stacked configuration, the industry can explore new Dimensions of computing power. While this level of advancement may still seem distant, it highlights the incredible potential and exciting future of the silicon industry.
5. Conclusion
In conclusion, the future of silicon lies in a combination of 3D stacking, chiplets, and megalithic dies. While megalithic dies may have a niche application, the majority of the industry will continue to focus on 3D stacking techniques. The upcoming waves of performance increases, built around these methodologies, promise revolutionary advancements in efficiency and computing power.
