what does a smaller cpu dye do?

what does a smaller cpu dye do? intels 6800k has 8 cores on 14nm dye when amd has a 8 core on a 32nm dye. is it just adding more trainstors?

14/32nm doesn't refer to the die size but rather the spacing between transistors.

and how does that help?

they can fit more transistors into a chip

At 14nm you can fit more transistors in the same amount of space. More transistors = faster performance (assuming you're comparing the same architectures -- performance/efficiency is dependent on a multitiude of factors -- architecture, frequency, manufacturing node, # of transistors, etc...)

 

So take the GTX1080 and GTX980Ti for example, a 1080 is 314mm while a 980Ti is 601mm yet the 1080 has a similar number of transistors while being almost half the size.

Smaller transistor sizes are also more power efficient.

A smaller manufacturing node, allows you to increase the amount of transistors set in a limited area and it also allows for better efficiency so it uses less power. eg. when Haswell's 22nm went to skylakes 14nm (poor broadwell, forever forgotten) the smaller node allowed a lower tdp. We didn't see much of an performance increase from Haswell to Skylake was because instead of putting more transistors down they decided to go for efficiency.

Note: The same architecture. Some CPUs cannot be compared directly. (I'm not disagreeing with you, I'm highlighting a key point)

look at it like this:

 

the processor is a company the transistors on the processor are offices.

the closer the offices are together the faster they can communicate, the less energy it takes, and the more offices they can put inside the company building.
