None 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. Proc

None 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.
