AMD FSR 4 vs NVIDIA DLSS 4: Why AI Upscaling Has Leveled the Playing Field
The Turning Point in AI Upscaling In 2025, AMD’s FidelityFX Super Resolution 4 (FSR 4) emerges as the first true challenger to NVIDIA’s dominant DLSS (Deep Learning Super Sampling) technology. Leveraging dedicated AI hardware acceleration on RDNA 4 GPUs like the RX 9600 XT and RX 9700 XT, FSR 4 finally matches DLSS 4’s visual quality and performance improvements that previously seemed unattainable for AMD’s software-only solutions. This article provides a detailed technical analysis of FSR 4, compares it with DLSS 4, and explores its impact on gaming performance, ecosystem dynamics, and GPU market competition. Hardware Acceleration: From Software-Only to AI-Optimized FSR 4’s AI Hardware Acceleration Unlike earlier AMD upscaling versions relying solely on software algorithms compatible with all GPUs (but limited in quality), FSR 4 introduces dedicated AI hardware acceleration exclusively on RDNA 4 graphics cards. This mirrors NVIDIA’s Tensor Core approach that enables DLSS’s advanced temp…
