The GTX 780 Ti has more Texture Mapping Units and slightly more shaders than the GTX 980 Ti...is this a big factor?

Kindly see the link for the head to head.

Other than those 2 specs, the 980 Ti blows the 780 Ti out of the water. But i am more particular with the afforementioned specs.

Thanks

No, it's a different architecture so a given number of shaders or texture units doesn't deliver the same performance.

Regardless of those number the change in architecture gives the win in performance to the 980Ti. 980Ti is refined so it can use its resources better.

Your link is comparing the GTX 980 Ti to the TitanX. The GTX 780 Ti has more shaders than the GTX 980 Ti, but it is different architecture, so they can't really be compared on a one to one basis.

The article also compares the GTX 980 Ti to the GTX 780 Ti. Anyway, it actually explains what's going on, at least cursorily:

For example, even though the 980 Ti has fewer cores than the 780 Ti, the Maxwell 2.0 cores are more efficient. GTX 980 is already able to match or slightly exceed the performance of the 780 Ti with 2048 cores

Thanks guys...everything clear now.

the shaders and tmus from maxwell perform about 90% more instructions per clock than kepler.
