The Voodoo 4500 is mostly register compatible with the Voodoo 3000. Some Voodoo 3000s have faster memory and maybe faster PCI throuput than the Voodoo 4500. The memory and PCI setup may not be as optimum in the driver as for the Voodoo 4500 as well. The Voodoo 3000 is faster for some operations and the Voodoo 4500 for others on my machine. The Voodoo 4500 is faster when the GPU is taxed which is rare on the Amiga. The Voodoo 4500 on the Amiga currently has the advantage of more memory, 15 bit mode support and sharper image. I may eventually modify the Warp3D driver with greater than 256x256 textures as well. The Voodoo 4500 can also do full color 3D and full screen anti-aliasing but they would be more difficult to implement.
