Oct 3, 2024

Lecture Notes on AMD's FSR 4

Introduction

  • Speaker: Paul
  • Announcement: AMD has announced that FSR 4 is in development, based on AI technology.
  • Goals: Improve image quality, maximize power efficiency, and enhance performance.

Background on FSR

  • FSR (FidelityFX Super Resolution) has been beneficial for both gamers and developers.
  • DLSS vs FSR: DLSS may have a quality edge but is limited to RTX cards, while FSR is compatible with a wider range of hardware, including Pascal, RTX, AMD cards, and consoles.

Interview Insights

  • Interview with Jack Hun from AMD (source: Tom Hardware).
  • Handheld devices: Battery life is a primary focus.
    • Example: Asus Rog Ally, Lenovo devices have limited battery life during gaming.
    • Solution: AI-based frame generation and interpolation to increase efficiency and battery life.

Technical Details and Future Plans

  • FSR 2 and 3 were analytic-based; FSR 4 will pivot to AI-based technology.
  • AMD Fluid Motion Frames 2: Early technical preview for Ryzen AI 300 series.
    • Impact: Significant FPS improvement demonstrated in benchmarks (e.g., Far Cry and F1 23).
  • Compatibility: Expected to run on a wide range of GPUs without requiring an NPU.
  • Potential modes similar to Intel's XESS, adapting based on hardware configuration.

Future GPU and Technology Speculations

  • RDNA 4 and RDNA 5: Upcoming changes and expected improvements in matrix operations.
  • Hypothetical: FSR 4's adaptability to Nvidia GPUs using Tensor Cores.
  • FSR 4 expected to introduce additional features beyond AI speed.

Comparison with Sony and DLSS

  • Sony's PSSR: Sony's internal upscaling efforts and how they might compare or influence FSR 4.
  • DLSS 4: Speculative murmurs about the next iteration of Nvidia's solution.
    • Overall anticipation for advancements in upscaling solutions.

Conclusion

  • Enthusiasm for the potential and future developments of FSR 4.
  • Closing remarks: Encouragement for listeners to have a great day.
