Re: Vertcoin-Adaptive N-factor Scrypt-No more ASICs-[EXCHANGES/AMAZON/ATM/MERCHANTS]

What is power consumption for n-factor coins? I mean is there a difference comparing to usual scrypt coins?

Unchanged for "low" NFactor coins - say N=4 to N=12 or so. When you start getting to N=13 and N=14, you can mine effectively with low power GPU's, and configure your GPU to use fewer shaders for the amount of memory you have.

That sounds interesting. Could you go a little more into detail plz. What would that mean in terms of power consumption? What do you mean with "low power GPUs"?

The power used by the gpu is mostly used by the shaders. Each shader uses some memory for the program and another bigger chunk for the data (the amount varies with the n-factor). As the n-factor increases the graphic cards will no longer have enough memory to use all the shaders, so the power used will decrease (and so will the hashing speed).
