Smaller distance -> lower resistance -> less heat -> higher clocks/more stuff per clock allowed with same amount of heat produced -> higher performance.

- marcosdumay 6y agoA chip is not composed of cylindrical wires. Smaller dimensions means you can set a smaller length for the wire. As you can see on the diagram on this article, there is a large push into increasing the height of the transistors. That has being going on for more than a decade. About the width, a finer process means you can keep the width of the most critical transistors the same, but can also trade it off into less width (and performance) where it is less important. So, overall, smaller dimensions leads to lower resistances. You can trade some of the gain for density, but you'll always get some lower resistance.
- systemvoltage 6y agoNone of these reasons are as important as transistor count / mm^2. If you can shrink die size in half, you can effectively reduce its cost by half as well. Processing wafers through 400 steps in the fab and its capacity is limited by how many useful chips you can build on a given 300mm wafer.
