You simply cannot answer a question like that! Let me restate your

"Let's assume that we invent some mechanism for binding 1024
cpus into a single box. I know it doesn't exist yet, but how
fast will it be?"

Binding that many CPUs together is hard! You tell me how you plan to do
it, and _then_ I'll tell you whether clustering is faster. :)
