My video card has less ram than his
but your CPU is much better and with the latest improvements in Blender (that are coming in 3.0) they are using more and more multi-threading and then the difference (in speed) between 8 and 24 cores will be more noticeable!
Also, the GPU mostly makes a difference when rendering. Modeling and Sculpting and so, only use CPU, when I am not mistaken…
