Intel is the first GPU manufacturer to offer AV1 encoding capabilities arc drawings sequence. We were lucky enough to see the coding in action thanks to YouTuber Eposvox, who tested the technology on an Arch A380 graphics card. The YouTuber has discovered that the AV1 is more efficient at producing video streams at a lower bit rate. It outperforms all H.264 hardware encoders, such as competing NVIDIA’s NVENC encoder.
Intel AV1 encoder outperforms Nvidia’s NVENC H.264 video codec
Many videos viewed daily on YouTube have adopted the new AV1 encoding, Especially in the growth of the last few years. Intel AV1 Video Codec It was initially developed by the Alliance for Open Media in 2015 as an open source and royalty-free video coding format. The format is theoretically revolutionary and free, giving users greater access to use online. AV1 produces smaller file sizes than the H.264 format, providing much greater compression capabilities.

Over the past several years, AV1 has seen increased adoption in video streaming platforms and seen more extensive use in graphics card architectures such as NVIDIA’s RTX 30 series, AMD’s RDNA 2 architecture, and more recently Intel’s iGPUs. Sony has also integrated the technology into the PlayStation 4 Pro gaming system.
AV1 does not see full use in content creation, especially broadcasting, even with video encoding available. Current graphics drivers do not support the AV1 codec. With the help of the program, the computer processor can use the AV1 codec. However, apart from the latest Intel Arc graphics cards, no hardware that can properly accelerate AV1 encoding has been developed.
In the video above, EposVox puts the Intel® AV1 encoder to the test once morest various H.264 encoders. The testing included software options available on broadcast suites such as AMD’s AMF, Intel’s Quick Sync, NVIDIA NVENC, and OBS broadcast software.
The YouTuber used Netflix’s VMAF benchmarking tool, which allows the user to parse a video quality from 0 (considered unwatchable) to 100 (best video quality imaginable). The benchmark tool compares video quality to uncompressed video and tests speeds of 3.5 Mbps, 6 Mbps, and 8 Mbps.
Battlefield 2042 video footage was used. At 3.5 Mbps, Intel’s AV1 video encoder scored 83 points, and at 6 Mbps, it hit 90 points out of 100. On the other hand, NVIDIA NVENC scored 71 points with an average of 3.5 Mbps, but scored 85 points at 8 Mbps. AMD and its AMF encoders were similar to NVIDIA’s, and Intel’s Quick Sync encoder hit 76 and 87, respectively. Intel is currently using a fast sync encoder on the Alder Lake platform.
A benchmark test prepared by EposVox showed that the Intel AV1 video codec had sixteen percent better performance than NVIDIA and AMD.
OBS delivered surprising results with the H.264 VerySlow pre-certified x264 encoder. The bundled programs delivered 78 points at 3.5 Mbps and 88 points at 6 Mbps. However, for broadcasting, this is not a usable format, so it is best that streamers avoid the system altogether.
Since EposVox has trained users to broadcast in general, it’s worth noting that 3.5Mbps is a fun and accessible setting for viewers when using Intel and AV1 codecs. It produces achievable stream quality while using fewer resources than competing companies.
