With the current prices of graphics cards, it may be more economical to make them out of diamonds...

I know you joke, but with the existing costs of fab manufacturing I wouldn't expect that using a diamond substrate would take up that much of the cost.

New diamond manufacturing processes include chemical vapor deposition, which would make integrating with fab processes pretty feasible. I'd guess it depends on weighing the performance graphene can offer vs the cost increase over silicon.

That is honestly pretty freaking cool.

Afaik synthetic diamonds are nowhere nearly as expensive as natural ones. Diamonds are just carbon after all.

So far as I know, no one can grow diamonds as big as wafers so I think it's sort of moot. Some other process like vapor deposition would probably be used rather than starting from a giant block of diamond.
