In that case, it will have implications on the gaming performance of your CPU as it will also be occupied by video encoding operation. But suppose you are gaming on the same computer from which you are gaming. X264 efficiently performs this task by compressing high-quality videos in small packets.
Twitch has a maximum upload speed of 6Mbps it isn't much if you are trying to compress 60fps 1080p video and upload it for live streaming. The essential requirement in live streaming is to convert and compress the video data into small packets due to limitations in the upload speed of platforms like Twitch. The comparison between CPU vs GPU encoding was all about performance vs quality. It features psychovisual enhancements which increase the subjective video quality of the video encoded by x264. It uses the CPU cores to encode videos for live streams in h.264/MPEG formats. X264 is a software-based video encoder developed by the VideoLAN. Consume very low power while encoding at high quality.Enable very high-quality encoding to archive, stream, and create web videos.
NVENC enables the streamer to encode and stream games plus applications with high quality and low latency excepting the CPU. In that case, you can reserve your CPU for game performance optimization and other tasks.
You can choose to completely dedicate the encoding process to NVENC and keep your CPU free for other tasks.įor example, suppose you are recording and streaming a game on a platform like Twitch or YouTube using OBS (Open Broadcaster Software) and dedicate the encoding to NVENC only. NVIDIA's hardware video encoder NVENC provides fast real-time hardware-based video encoding without interfering with the graphics performance. NVENC supports fast real-time video processing. Hardware-accelerated encoding is suitable for streaming applications, video transfer along video playback due to real-time video processing. It is a hardware-accelerated video encoding tool by NVIDIA (hence, referred to as NVENC). NVIDIA uses a hardware encoding mechanism called NVENC. What is NVENC?Īll the GPU units in the market use a decoder and encoder. Let us first make you familiar with the basics of video encoding and decoding and how it works. Nvenc vs x264 streaming encoding performance is based on the platform that you are trying to launch your stream on. There are two types of video encoding mechanisms widely used and popular with gamers and streamers. Many companies are producing Graphics processing units, generally known as GPU’s to enhance gaming and streaming performances.
