When mentioning the use of 6 chips in parallel, it's common for people to overestimate its impact. Understanding the design of closed-source market ASIC machines, like the Antminer S21 with its three hash boards, is key. Each hash board contains 108 ASIC chips, resulting in a total of 324 chips. This brings power consumption into consideration.

In my opinion, it's all about the cost per unit of hashing power, and they rank quite well in this aspect. The future will tell where this leads us.
