Intel’s AV1 Encoder Outclasses NVIDIA & AMD

Intel is the first GPU manufacturer to give AV1 encoding abilities inside of its Arc graphics lineup. Many thanks to YouTuber EposVox, who analyzed the technological innovation on an Arc A380 graphics card, we were fortunate to see the encoding in motion. The YouTuber found that AV1 is remarkably effective for video streams that make a very low little bit rate. It outperformed all H.264 hardware encoders, this sort of as the NVENC encoder from rival NVIDIA.

Lots of videos on YouTube that are viewed day-to-day have adopted the new AV1 encoding, specifically more than the past couple of a long time of progress. Intel’s AV1 video encoding was at first designed by the Alliance for Open up Media as a royalty-free open-resource online video coding structure in 2015. The format is innovative in idea and free, letting it to be additional accessible for people to benefit from via the Web. AV1 generates less file dimensions than the H.264 structure, presenting a vastly more substantial compression ability.

In the very last numerous decades, AV1 was ever more adopted in online video streaming platforms and has viewed far more substantial use in graphics card architectures, these types of as the NVIDIA RTX thirty collection, AMD’s RDNA 2 architecture, and not too long ago in Intel’s iGPUs. Sony also integrated the engineering in the PlayStation four Professional console gaming method.

In written content creation, primarily in streaming, AV1 has not witnessed full utilization, even with the movie encoding offered. Present graphics engines do not provide support for AV1 encoder engines. With software support, a system’s processor can benefit from the AV1 codec. Nonetheless, hardware that can accelerate AV1 encoding adequately has in no way been formulated, besides for Intel’s latest Arc graphics playing cards.

In the previously mentioned video, EposVox placed Intel’s AV1 encoder and analyzed the technological know-how towards several H.264 encoders. Bundled in the testing ended up AMD’s AMF, Intel’s Brief Sync, NVIDIA NVENC, and software program selections out there in streaming deals, these as the streaming software program OBS.

The YouTuber employed Netflix’s VMAF benchmark tool that allows the consumer to evaluate video clip high quality with a scoring of (which would be regarded not possible to enjoy) to one hundred (the very best high-quality of movie conceivable). The benchmark resource compares the video high quality to uncompressed movie and is examined at three.5MBps, 6MBps, and 8MBps.

The movie applied was footage from the game Battlefield 2042. At three.5MBps, Intel’s AV1 movie encoder scored 83 points, although at 6MBps, it attained 90 out of a hundred factors obtainable. On the other hand, NVIDIA NVENC scored seventy one at 3.5MBps, but 8MBps accomplished eighty five details. AMD and its AMF encoder ended up equivalent to NVIDIA, and Intel’s Speedy Sync encoder reached 76 and 87, respectively. Intel makes use of the Swift Sync encoder in the Alder Lake system at present.

The benchmark examination manufactured by EposVox reveals that the Intel AV1 online video codec has an enhance of sixteen % greater general performance than NVIDIA and AMD.

OBS offered shocking final results with its H.264 program-primarily based encoder preset, x264 VerySlow. The integrated application supplied seventy eight factors at three.5 MBps and 88 at 6MBps. Having said that, for streaming, it is not a usable structure, so streamers would better keep away from the location altogether.

As EposVox has educated users on streaming in common, it is notable that 3.five MBps is a lot more available to viewers and the sweet setting when working with Intel and the AV1 encoding. It produces a extra offered stream high quality while using much less sources than rival corporations.
