No, not at all. I have been working in Semiconductor fabs for 20 years. But it depends on how they designed the chips. If you shrink the geometries inside a chip, you do save on power consumption and gain speed. This means you can also fit more transistors inside the same size packaged chip. So the question left is if Ebang/Samsung used the same amount of transistors to shrink the package size of the chips, or did they increase the amount of transistors inside each chip? It is also possible that they increased the clock speed (frequency) of the chips as well. Where smaller geometries produce less heat, you could increase the clock speed to obtain higher hash processing speeds. Either way, putting more chips on the board will require more wattage and so will increasing the clock speed.
