Bitmain S21 HYD vs S21 Pro

[Raynor]

Hello All,

I've started looking into immersion cooling and wanted to ask - are these two Bitmain Models essentially the same hardware with different cooling system and software tune?
S21 HYD vs S21 pro.

In other words - are they different chip-wise or it's the same thing only the HYD model is tuned to a higher Hashrate.

If it's not the case - I would greatly appreciate if you point out the differences so I can better research it.

Thank you.

The review says that the chips are the same, but the boards are different and, accordingly, the number of chips in each model is different.

Both miners use BM1368PB chips,  the difference is not be only in the cooling but in the number of chips, I think the S21 pro has 108 chips on each hashboard, a total of 324 chips onboard, the S21 hydro on the other hand holds 216 chips on each board, a total of 648 chips.

You mentioned immersion cooling which doesn't go with hydro/water cooling, I hope you are aware of the differences between the two types of cooling.
