Notice rops in the Gk110 whitepaper? They aren't listed in the specs when comparing it to previous architectures, just texture units

First do you see any major difference between the high level block diagram of Kepler and pascal in terms of something that says 'ROPS' on it and something that doesn't? Anandtech point out it has rops in the memory controller block but Nvidia themselves don't focus on rops, don't list ROPs on their Tesla cards and didn't list them in any information about previous Tesla cards.
Now compare the comparison specs on these pages

Tesla launch comparison table, no rops, Titan based off the exact same core, rops included in the comparison.
Rops are entirely irrelevant to Telsa and Nvidia don't talk about them, I do think that at some stage Nvidia might well make a fully compute card and save the transistors and this generation might be that generation. But people are jumping to a lot of conclusions about it based off things they are just entirely guessing that mostly fly in the face of all previous cards(which again is possible, just not likely).
