Why doesn't my Gigabyte RX 5500 XT Gaming OC 4Gb play 8k YouTube videos?

I bought a machine with the following configurations:

   • Processor: AMD Ryzen 5 3600X
   • Motherboard: Gigabyte B450 Aorus M
   • Memory: 2x8Gb DDR4 3200Mhz
   • Graphics Card: Gigabyte Radeon RX 5500 XT Gaming OC 4Gb
   • SSD: Kingston A400 480Gb
   • Font: Corsair CV550
   • System: Windows 10 Pro (version 10.0.19041)

In the video card specifications, on the Gigabyte website (, informs that it reaches 8K resolution (7680x4320px), but it is unable to play videos on YouTube at this resolution, it gets stuck. In 4K it runs smooth, but not 8K. I tested it with this video here:


My Ideapad 320 notebook with Core i5-8250U, 8Gb, HDD and GeForce MX150 2Gb video card runs this video perfectly and still using only the integrated video card. However, on the notebook I saw that more processor (~ 25%) and 3D GPU (~ 50%) are used, and not Video Encode, as with Radeon (see image above).

   • Is something wrong with my card or my system?

   • What could be happening?

   • Could anyone help me with this issue?
