When NVidia came out with the 700 series, they rebranded the old 600 series GK104 GPUs. The 670 became the 760, and the 680 became the 770.
You need to look at a 780/780Ti or GTX Titan to get a "real" new GPU in the 700 series (GK110).
670 is stronger - you might be thinking of 660ti.
It (670) has 7 smx: 1344:112:32 layout (cudas, tmu's, rop's)
760 has 6 smx: 1152:96:32 layout (cudas, tmu's, rop's)
Since they both have same VRAM, rops etc, 670 would be up to ~17% faster with linear scaling but often less
760, 660ti, 670, 680 and 770 are all gk104, but they have:
760: 6smx, full rop's/bus
660ti: 7smx, 25% rop's and memory bus width sacrificed
670: 7smx, full rop's/bus
680: 8smx, 6ghz stock vram
770: 8smx, 7ghz stock vram
Therefore 770 > 680 > 670 >760/660ti (can beat eachother in different loads as 660ti gains an smx but loses memory bandwidth and rops)
Given that these are all gk104 and there's no meaningful differences for actual load clocks, i tend to ignore stock clocks for core too - that gives a bit of a bump for some cards over others at stock, kind of artificially.
