How ASIC Miners Are Made: From Silicon Wafer to Finished Device

An ASIC is not simply a graphics card in a metal case. It is a specialized manufacturing chain in which the mining algorithm is built into the chip logic and the entire design is optimized for a particular task.

The main stages

First, engineers design the chip logic and the masks used for manufacturing. Billions of transistors are formed on a silicon wafer, after which individual dies are separated, tested and packaged.

The chips are then installed on a hashboard. Voltage regulators, controllers, memory, a control board, heatsinks and fans are added. A finished ASIC is tested for hashrate, consumption, stability and temperature.

Why a newer process node does not guarantee a better miner

A smaller process node can increase transistor density and efficiency, but the real device also depends on architecture, frequency, voltage, cooling, the power supply and manufacturing quality.

That is why you should compare more than the chip name: look at J/TH or J/KSol, stable hashrate, warranty, price, noise and repair availability.
