1 week ago - Nvidia chips also feature an onboard decoder, NVDEC (short for Nvidia Decoder), to offload video decoding from the CPU to a dedicated part of the GPU. NVENC has undergone several hardware revisions since its introduction with the first Kepler GPU (GK104).
Help me understand the NVENC encoder chips
3 hardware encoders just means you can run three simultaneous encodes without any real performance loss. After that things can become a bit funky but should still work fine to a point. In most cases you won't notice it unless you're doing something like ffmpeg batch encoding. More on reddit.com

NVidia NVENC hardware acceleration in Nimble Transcoder – Softvelum: efficient tools to build your streaming networks
This dedicated accelerator encodes video at higher speeds and power efficiency than CUDA-based or CPU-based encoders at equivalent quality. NVENCODE API allows the programmer to control various settings of the encoder to set the desired trade-off between quality and performance. Nimble Streamer Live Transcoder has full support for NVidia video decoding and encoding hardware acceleration.

r/nvidia on Reddit: Help me understand the NVENC encoder chips

Concise:
What does having 3 encoder chips in one Graphic Card enable me to do?
Background:
I currently have an RTX 3060. I stream to YouTube while recording. My recorded stream uses a much higher bit rate than the live stream. On one occasion I got a Skype call during a stream I noticed an increase in the Task Manager under GPU Video Encode. This suggest to me that my encoding chip was encoding three video streams at the same time.
I have read that I can get up to 5 with an updated driver and most recently 8 simultaneous streams.
I have read that the new RTX 5090 has 3 encoder chips. What does that enable? Do I need to wait for OBS to support this new feature?

Do I need to wait for OBS to support this new feature? No, the encoding limit is driver based and can be bypassed: https://github.com/keylase/nvidia-patch/tree/master/win As you mentioned, in the past year nvidia increased the limit imposed by the driver and now the baseline is 8 encodes. https://developer.nvidia.com/video-encode-and-decode-gpu-support-matrix-new Technically, you can have an as many encodes going as you want - at a certain point frames will drop due to the hardware not being able to keep up, so that's why nvidia has a limit in the drivers.

The first sign of knowing whether your PC supports these features is to go into Studio and check Settings: Streaming for Hardware Encoding, then check Settings: Advanced for Hardware Decoding. If these options do not appear in these menus, then, unfortunately, you do not have the supported hardware. We have successfully tested the following NVIDIA GeForce models: ... To find out if a specific model supports these features, visit the NVIDIA GPU Support Matrix. The first table on this page represents cards that support hardware encoding (NVENC); the second table (below) is for cards that support hardware decoding (NVDEC).

NVENC Application Note
For example, in a game recording scenario, offloading the encoding to NVENC makes the graphics engine fully available for game rendering. In the video transcoding use-case, video encoding/decoding can happen on NVENC/NVDEC in parallel with other video post-/pre-processing on CUDA cores.

March 6, 2026 - The process operates asynchronously on supported platforms, allowing multiple frames to be queued while outputs are retrieved upon completion signaled by events.[9] Motion estimation forms the core of inter-frame prediction, where NVENC performs block-based searches to compute motion vectors between the current frame and reference frames stored in the Decoded Picture Buffer (DPB).
