At the moment that's a little difficult. The problem is that Nvidia have since Fermi had cards which are designed more as gaming chips and cards which are designed to be both gaming but heavily siding with compute performance chips.
The GK104 is the gaming performance chip and as such its DP is artificially capped reduced to allow for more gaming performance.
AMD have released the 7970 which has more compute performance compared to the cards it replaces.
So while these numbers are available I don't really see what comparing the cards on that basis would be worth.
