Very cool! I am wondering one thing: how fast is it? Much of the "secret sauce" of the Voodoo is its high speed: a first-gen Verite or (God forbid) any ViRGE takes many more cycles for common operations like, say, Z-buffered pixels.

I'm guessing this isn't fully cycle-accurate, but is it at least somewhat "IPC-accurate"? I'm guessing yes? But much of that was also derived from Voodoo's (for the time) crazy high memory bandwidth AFAIK.
