NVENC - Wikipedia
3 days ago - From November 2025 onwards, twelve simultaneous encoding video streams became the baseline. 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 ...

r/nvidia on Reddit: Help me understand the NVENC encoder chips
January 25, 2025 -
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?

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.

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.
