Intel Ruixuan A770 graphics card beats NVIDIA RTX 4090 in 8K AV1 decoding test

Intel Ruixuan A770 desktop independent display and NVIDIA RTX 4090 desktop independent display have been released recently. The developers of the performance analysis tool CapFrameX have now released several high-end graphics cards for video decoding. Unlike game performance, the video decoding capability does not depend on the overall performance of the GPU but also tests the individual video decoding hardware capabilities. In testing, Chrome played AV1 YouTube videos in 4K and 8K resolutions.

At 4K resolution:

• The average frame of the Intel Sharp A770 ran at 60FPS, dropped to 44.8FPS in 1% of the cases, and dropped to 44.1FPS in 0.2% of the cases
• Both the Nvidia RTX 3090 and RTX 4090 also averaged 59.9 fps
• The AMD RX 6800 XT averages only 55.8FPS, with a small probability that it will drop to 12.2FPS

To the 8K tests:

• The advantage of the Intel Ruixuan A770 is more obvious, the average frame is 59.9FPS, and the performance is almost unaffected
• Nvidia's two high-end graphics cards can only maintain around 57FPS, and there is a small probability that the frame will drop to 17FPS
• The AMD RX 6800 XT performed the worst, with an average frame of only 22FPS, and even the basic 24FPS requirement for movies could not be met, and there would be a perceptual stutter when watching

As one of the founding members of the Open Media Alliance, Intel has done a lot to promote the AV1 codec, taking the lead in providing hardware AV1 decoding through its Xe-LP GPU in 2020. For the first time, the Ruixuan independent display supports complete AV1 hardware acceleration, which is 50 times faster than software acceleration. Adobe Premiere Pro, DaVinci, and other software have supported AV1 hardware acceleration such as Intel, so the advantages in the 8K test are also expected.

And AMD has always been unsatisfactory in encoding and decoding, and we can expect to see if the RX 7000 series can improve . AMD RX 7000 series graphics cards will be released in early November and are expected to be available in December.
