Already touched this topic barely in another thread https://lists.cinelerra-gg.org/pipermail/cin/2023-December/007346.html But so many SW and HW pieces are mentioned around, it is almost a full-time reading and study: VAAPI, MESA, VULKAN, Intel Quick Sync Video etc...... I realize my aging hardware which is fast enough for other tasks, needs some "AV1 upgrade", if possible. But first I wonder, what is expected possible to do (obtain) with AV1 de-/encoding on my existing 64bit hardware: 1) laptop 2018: Dell XPS 13-9370: quad core i7-8550U CPU (8. gen Kabylake) and Intel UHD Graphics 2) WS infinity: MSI Z170A mobo: quad core i7-6700K CPU (6. gen Skylake), NVIDIA GeForce GT-730 graphics A budget friendly first "AV1 HW upgrade" of the workstation 2) if possible, would be to add a new GPU as Intel Arc A380. But the question is if this will work at all on that much older (2015) Skylake platform with i7-6700K CPU? I've seen CPU bottlenecks has been mentioned and that Arc A380 is targeted at newer generations CPU ...
