In a new blog post titled “AV1 Streaming Dazzles on GeForce RTX 40 Series GPUs With OBS Studio 29.1 Launch and YouTube Support,” NVIDIA shared a comparison shot that suggests its NVENC AV1 encoder provides vastly better results than what AMD and Intel can provide with their respective encoders. The shot features a house from Fortnite, and while its roof shingles and door emblem are pretty clear in the NVENC example, both are kind of a blurry mess in the results for the competition. NVIDIA noted that all GeForce RTX 40 Series GPUs support real-time AV1 hardware encoding, providing “40% more efficient encoding on average than H.264 and delivering higher quality than competing GPUs.”
From an NVIDIA post:
GeForce RTX 40 Series GPUs usher in a new era of high-quality streaming with AV1 encoding support on the eighth-generation NVENC. A boon to streamers, NVENC offloads compute-intensive encoding tasks from the CPU to dedicated hardware on the GPU.
Designed to support the rigors of professional content creators, NVENC preserves video quality with a higher accuracy than competitive encoders. GeForce RTX users can stream higher-quality images at the same bitrate as competitive products or encode at a lower bitrate while maintaining a similar picture quality.
