Respuesta a "Can I upgrade my i3 8100 to a i9 9900t?"I accidentally found this video. https://www.youtube.com/watch?v=pAdYWkXJ... The guy upgraded 2019 21.5 with i9 9900t CPU, so yes it works, tho i have no idea how well. I gonna try to put same CPU in my 2019 27 inch one and see myself. 220$ worth to try!
