Intel’s AV1 Encoder Outclasses NVIDIA & AMD

Intel is the primary GPU producer to supply AV1 encoding capabilities inside its Arc graphics lineup. Due to YouTuber EposVox, who examined the know-how on an Arc A380 graphics card, we have been fortunate to see the encoding in motion. The YouTuber found that AV1 is extremely environment friendly for video streams that produce a low bit charge. It outperformed all H.264 {hardware} encoders, such because the NVENC encoder from rival NVIDIA.

Intel AV1 Encoder outperforms rival NVIDIA’s NVENC H.264 video codec

Many movies on YouTube which are watched each day have adopted the brand new AV1 encoding, particularly over the previous few years of growth. Intel’s AV1 video encoding was initially developed by the Alliance for Open Media as a royalty-free open-source video coding format in 2015. The format is revolutionary in principle and free, permitting it to be extra accessible for customers to make the most of through the Web. AV1 produces fewer file sizes than the H.264 format, providing a vastly bigger compression functionality.

Within the final a number of years, AV1 was more and more adopted in video streaming platforms and has seen extra intensive use in graphics card architectures, such because the NVIDIA RTX 30 collection, AMD’s RDNA 2 structure, and just lately in Intel’s iGPUs. Sony additionally built-in the know-how within the PlayStation 4 Professional console gaming system.

In content material creation, particularly in streaming, AV1 has not seen full utilization, even with the video encoding obtainable. Present graphics engines don’t provide help for AV1 encoder engines. With software program help, a system’s processor can make the most of the AV1 codec. Nonetheless, {hardware} that may speed up AV1 encoding correctly has by no means been developed, aside from Intel’s latest Arc graphics playing cards.

Within the above video, EposVox positioned Intel’s AV1 encoder and examined the know-how towards a number of H.264 encoders. Included within the testing have been AMD’s AMF, Intel’s Fast Sync, NVIDIA NVENC, and software program choices obtainable in streaming packages, such because the streaming software program OBS.

The YouTuber used Netflix’s VMAF benchmark instrument that enables the consumer to research video high quality with a scoring of 0 (which might be thought-about not possible to look at) to 100 (the highest quality of video conceivable). The benchmark instrument compares the video high quality to uncompressed video and is examined at 3.5MBps, 6MBps, and 8MBps.

The video used was footage from the sport Battlefield 2042. At 3.5MBps, Intel’s AV1 video encoder scored 83 factors, whereas at 6MBps, it reached 90 out of 100 factors obtainable. Alternatively, NVIDIA NVENC scored 71 at 3.5MBps, however 8MBps achieved 85 factors. AMD and its AMF encoder have been just like NVIDIA, and Intel’s Fast Sync encoder reached 76 and 87, respectively. Intel makes use of the Fast Sync encoder within the Alder Lake platform presently.

The benchmark take a look at produced by EposVox reveals that the Intel AV1 video codec has a rise of sixteen % higher efficiency than NVIDIA and AMD.

OBS supplied shocking outcomes with its H.264 software-based encoder preset, x264 VerySlow. The built-in software program supplied 78 factors at 3.5 MBps and 88 at 6MBps. Nonetheless, for streaming, it’s not a usable format, so streamers would higher keep away from the setting altogether.

As EposVox has educated customers on streaming on the whole, it’s notable that 3.5 MBps is extra accessible to viewers and the candy setting when utilizing Intel and the AV1 encoding. It produces a extra obtainable stream high quality whereas using fewer assets than rival firms.
