This series is renowned for introducing DLSS 3, a revolutionary AI-powered performance multiplier that dramatically boosts frame rates by generating entirely new frames.

The Ada Lovelace Architecture: Foundation of the 40 Series

At the heart of every RTX 40 Series card is NVIDIA’s Ada Lovelace microarchitecture, named after the 19th-century mathematician Ada Lovelace. This architecture is fabricated on TSMC’s custom 4N process, specifically designed for NVIDIA, which provides significant improvements in power efficiency and transistor density over previous generations. The Ada Lovelace architecture integrates specialized processing units within its Streaming Multiprocessors (SMs), each containing 128 CUDA cores, fourth-generation Tensor Cores, and third-generation RT Cores.

  • CUDA Cores: These are the workhorses for general-purpose computing and traditional rasterization. Ada Lovelace’s CUDA cores are an evolution from the Ampere architecture, offering concurrent FP32 and INT32 execution for increased efficiency.
  • Third-Generation RT Cores: These dedicated cores significantly accelerate ray tracing workloads, offering up to twice the ray-triangle intersection throughput compared to Ampere’s second-generation cores. This enables more realistic lighting, reflections, and shadows in real-time gaming. New features like Shader Execution Reordering (SER) further optimize ray tracing efficiency by dynamically reorganizing shading workloads.
  • Fourth-Generation Tensor Cores: Critical for AI acceleration, these Tensor Cores introduce FP8 precision support, leading to up to 4x higher inference performance over the previous generation. They are instrumental in powering features like DLSS 3, enabling faster AI inference for applications beyond gaming, such as generative AI and natural language processing.

The architecture also features a revamped Level 2 cache, with the flagship AD102 GPU boasting 98304 KB of L2 cache, a 16x improvement over the GA102 in the Ampere generation. Furthermore, Ada Lovelace GPUs incorporate dual NVIDIA Encoders (NVENC) with AV1 video processing support, offering up to 40% better encoding efficiency compared to H.264, which is a boon for streamers and video editors.

Key Technologies and Innovations

Beyond the architectural improvements, the RTX 40 Series brings several groundbreaking technologies that define its performance and user experience:

  • DLSS 3 (Deep Learning Super Sampling 3): This is a major highlight, exclusive to RTX 40 Series cards. DLSS 3 combines DLSS Super Resolution (upscaling technology from DLSS 2) with a new “Optical Multi Frame Generation” AI technology and NVIDIA Reflex low-latency technology. It uses AI to generate entirely new frames, rather than just upscaling existing ones, which can lead to a massive boost in frame rates—up to 4x faster compared to traditional rendering in some scenarios. This is particularly beneficial in CPU-bound scenarios, where the GPU can generate new frames independently of the CPU, effectively doubling frame rates.
  • Ray Tracing Enhancements: With third-generation RT Cores and innovations like Shader Execution Reordering (SER), the RTX 40 Series delivers significantly improved ray tracing performance, making real-time cinematic rendering more achievable and immersive.
  • NVIDIA Reflex: Integrated with DLSS 3, NVIDIA Reflex helps reduce system latency, making games feel more responsive.
  • Dual AV1 Encoders: The inclusion of dual AV1 encoders provides superior video encoding efficiency, benefiting live streamers and video content creators with higher quality streams at lower bitrates.

These technologies collectively contribute to the “beyond fast” performance narrative NVIDIA has championed for the RTX 40 Series, pushing the boundaries of what’s possible in PC graphics.
