CapFrameX recently measured the AV1 performance of mainstream graphics cards at 4K and 8K resolutions. The test players include Intel Arc A770 graphics card, NVIDIA RTX 4090, RTX 3090 and AMD RX 6800 XT four graphics cards and the RTX 3080 test results provided by WccFetch. The test results show that the AV1 performance of the A770 is better than that of the RTX 4090.
The video CapFrameX used in this test is a video called “Japan in 8K 60fps”. To initiate a proper capture on CapFrameX software, the application entry “chrome” needs to be removed from the application’s ignore list to find an appropriate capture and provide performance results.
Also, while playing a video, right-clicking on the video pulls up a menu list and also needs to provide a click on “Stats for nerds” so we can see the stats.
Here are the stats for CapFrameX:
The first AV1 test results are the average frame rate per second and the 1% and 0.2% percentile FPS of the four graphics cards
While Intel was the leader in the test, delivering 60 fps, the NVIDIA GeForce RTX 3090, RTX 4090, and RTX 3080 all delivered the same 59.9 fps for video. The AMD Radeon RX 6800 XT came in last, delivering 55.8 fps, a difference of 4.1 to 4.2 fps on the 4K resolution 60 fps test.
The test results of the “Japan in 8K 60fps” video in 8K resolution are as follows:
The Intel Arc A770 graphics card still topped the charts for AV1 encoding, producing 59.9 fps in 8K video. The NVIDIA GeForce RTX 4090, 3090, and my 3080 came in at 57.6, 56.8, and 56.7 fps, respectively, suggesting that NVIDIA’s support for AV1 encoding is better than the last-place AMD Radeon RX 6800 XT, which only managed 22 fps.
CapFrameX also provides Chrome AV1 8K video decode frame times, which shows that the AMD Radeon RX 6800 XT emits huge spikes of over 800ms every 4 seconds of video. Meanwhile, the Intel Arc A770 graphics card held the lead during the test and improved slightly at the end.
