As the core chip of NVIDIA RTX 4090 graphics cards, the performance leap of AD102-300-A1 stems from the all-round innovation of the Ada Lovelace architecture. This architecture, based on advanced technology, has achieved a generational breakthrough in graphics processing and computing capabilities through the upgrade of core modules and the empowerment of intelligent technologies.

　　The leap in manufacturing process and transistor scale is the foundation for performance improvement. The AD102-300-A1 adopts TSMC's 4N custom process, increasing the number of transistors to approximately 76 billion, achieving nearly a threefold growth compared to the previous generation architecture. The integration of denser transistors combined with an optimized circuit design has achieved a performance improvement of more than double under the same power consumption, providing a solid support for high-load scenarios.

　　The evolution of ray tracing capabilities has become a highlight of the architecture. The third-generation RT Core in the chip not only doubles the ray tracing performance, but also adds Opacity Micromap and Displaced Micro-Mesh engine. The former accelerates the light calculation of complex textures such as leaves and fences, while the latter achieves 9 times the speed of geometric modeling with only 1/20 of the video memory usage. Combined with shaders to perform reordering technology, the shading performance of ray tracing scenes can be increased by up to 2 times.

　　The collaborative upgrade of AI and graphic rendering has restructured the performance boundaries. The fourth-generation Tensor Core introduces the FP8 tensor engine, with inference performance increased by four times compared to the previous generation, providing a hardware foundation for DLSS 3 technology. With the help of optical flow accelerators to generate brand-new frames, DLSS 3 can double the frame rate without sacrificing picture quality, demonstrating significant advantages in 3A games. Meanwhile, the speed of the single-precision CUDA core has doubled, and the 96MB large-capacity L2 cache further reduces data latency, making graphics rendering and professional computing more efficient.

　　From gaming and entertainment to professional creation, the Ada Lovelace architecture endows the AD102-300-A1 chip with not only parameter growth but also an innovation in graphics processing logic, setting a technical benchmark for performance breakthroughs in high-end Gpus.
