I can't validate or attest to the accuracy, but the *actual* numbers 
I've seen in other articles is 1.16 (not 0.665 * 3) per K20 and around 
20Pflop for Titan.  We have to wait until Top500 is published to get 
actual numbers
Anyone with more 1st hand knowledge of the matter please feel free to 
correct me
