The 780, 780 Ti, Titan, Titan Black and Titan Z all use the same chip. The differences are as follows:
780: crippled core count, no dp float enabled, 3GB VRAM, highish clocks.
780 Ti: full core count, no dp float enabled, 3GB VRAM, high clocks (can be overclocked to have the highest)
Titan: reduced core count, dp float enabled, 6GB VRAM, high clocks.
Titan Black: full core count, dp float enabled, 6GB VRAM, highest clocks (but can be overtaken by a 780 Ti as it's not as great an overclocker, possibly due to the dp fp ALUs drawing power too or something like that)
Titan Z: 2x full core count, dp float enabled, 2x6GB VRAM, highish clocks
The integer support isn't different between the cards as for people who want to use the cards for compute purposes, the double precision floating point ALUs being enabled and the extra VRAM are already enough of an incentive to not buy the gaming cards. It's basically just Dolphin that uses integers so much for gaming purposes, and as it doesn't need huge amounts of VRAM or 64-bit floats on the GPU, a fully OC'd 780 Ti wins.
