vertex deduplication

[WdsPjm]

I have a question I would like to inquire about. For example, consider a cube. Typically, it only needs 8 vertices and 24 indices to be sent to the GPU for rendering. If mesh optimization is applied, such as vertex deduplication, would it potentially result in better performance?

Unsure what the question is about - isn't a cube with 8 vertices already perfectly deduplicated? fwiw typically a cube would have 24 vertices and 36 indices: 4 vertices per face because each corner has to have 3 copies to have 3 different normals, 6 indices per face because each face is two triangles.
