That's because you're talking rubbish.
1.3Tf is similar power to a GeForce GTX 560 according to Wikipedia. That's good enough for 1080p graphics and that's not in a closed box environment surround by tons of custom chips nor does it have eSRAM.
the bolded part is a bottleneck not an advantage, usually high-end cards have 1Gb of GDDR5.
EDIT: Beaten by a mere seconds
