Analyzing the Leaked Diagram of AMD’s Next-Gen GPU Architecture

Moore’s Law Is Dead

Rumors have been swirling that AMD may not release any high-end GPUs in the next generation of graphics cards, known as RDNA 4. However, a leaked diagram has recently surfaced, giving us a glimpse into what AMD’s best graphics card of the next generation could have been. The diagram, shared by YouTuber Moore’s Law is Dead, offers a partial view of the RDNA 4 architecture, hinting at its complexity and potential capabilities.

The leaked diagram showcases a large package substrate with four dies. One is labeled as the Multimedia and I/O die (MID), while the other three are referred to as Active Interposer Dies (AIDs). The AIDs seem to have the capacity to house up to 3 Shader Engine Dies (SEDs). Additionally, it’s speculated that there are memory controller dies and Infinity Cache dies present, although they are not depicted in the diagram.

One standout feature of the Navi 4C GPU, as inferred from the diagram, is the significant increase in chiplets. The architecture is believed to consist of anywhere between 13 to 20 chiplets, showcasing a departure from the current-gen design. This suggests that AMD has split and added more external interconnects, resulting in a more complex GPU architecture. The diagram also reveals a higher number of memory cache dies (MCDs), further contributing to the intricacy of the design.

While this increased complexity may potentially bring about significant improvements in the next generation of GPUs, it also poses challenges for the design and manufacturing process. AMD may have ambitiously taken on more than it can handle within the tight timeline, assuming that RDNA 4 is about a year away. Consequently, there’s a possibility that this design could be postponed until RDNA 5. However, it is unlikely that AMD would entirely withdraw from the high-end GPU market, as it has a strong presence and reputation to uphold.

Estimating the exact performance enhancements brought about by this experimental architecture is challenging. AMD made a strategic decision not to compete directly against Nvidia’s best GPU in the current generation, and there have been rumors suggesting that the company may not release high-end GPUs in the next generation. Nevertheless, based on the leaked diagram, it appears that when AMD eventually returns to producing powerful GPUs, it could pose a serious challenge to Nvidia.

In conclusion, the leaked diagram of AMD’s next-gen GPU architecture offers a captivating glimpse into what could have been or potentially will be. The increased complexity of the Navi 4C GPU has raised the excitement among enthusiasts and industry insiders alike. While the challenges associated with the design and manufacturing process are evident, AMD’s commitment to pushing the boundaries of performance remains unwavering. As the GPU race continues, it will be fascinating to see how AMD’s future releases will shape the landscape of high-performance graphics.
