AV1 Support: Better Quality for Your Live Stream

The NVIDIA Encoder: NVENC is an independent part of the GeForce RTX 4090 GPU. It is used to encode videos and offload the CPU. This allows your system to free up resources for games while streaming simultaneously, letting you focus on the essentials: a truly breathtaking broadcast. In the Ada GPUs, two NVENC encoders now support AV1, enabling 1440p streaming instead of 1080p with H.264 at the same performance. Additionally, the encoder and GeForce Experience ShadowPlay can record video material in 8K60 with HDR.

GeForce RTX 4090: The Ada Lovelace GPU Architecture

The Ada GPU architecture offers several optimizations over Ampere. The number of CUDA cores per SM (Streaming Multiprocessors) has increased from 84 to 128. An Ampere SM can perform either 128 FP32 or 64 FP32 and 64 INT32 calculations per workload. Each SM consists of four blocks, each with 16 FP32 ALUs and FP32/INT32 ALUs. Like Ampere, each SM has a ray tracing core.

With 128 SMs, the RTX 4090 thus has 16,384 CUDA cores (8,192 FP32 and FP32/INT32 ALUs each) and 128 ray tracing cores. The 128 SMs are divided into 7 GPCs (Graphics Processing Clusters) on the RTX 4090, and each SM has 4 tensor cores. However, the tensor cores in version 4 on the Ada GPUs are significantly more powerful than those on Ampere.

Ray Tracing Performance of the RTX 4090

Ada GPUs are equipped with a new technology called Shader Execution Reordering (SER), which can increase ray tracing performance by up to three times compared to the Ampere generation. Workloads are more efficiently sorted, and in-game FPS can increase by up to 25%.

Ray tracing (RT) enables realistic lighting by simulating the physical properties and behavior of light. RT is the calculation of the color of individual pixels as light travels from the user's eye through a 3D landscape. Light traverses the 3D scene, reflecting off objects or generating reflections, creating shadows, and producing transparent or semi-transparent objects. This results in light refractions or distortions.

Ray tracing combines all these effects to represent the final color of a pixel on the monitor. Until now, ray tracing has primarily been used in films to create special effects. Render farms are often used for these scenes, and calculating complex 3D animations and special effects for movies can take several weeks. Due to the complexity of ray tracing, PC applications such as computer games typically use 3D objects based on a raster model. In rasterization, 3D objects are modeled from a network of triangles or polygons. These triangles of the 3D model are converted into pixels on a 2D screen individually in the rendering pipeline. The pixels can then be further processed ("shaded").
