Correlation can be shown to be causation when all factors are both known and controlled for. Controlling for CPU prices is one step towards that goal.

  This is a circular argument. Why are CPU prices a confounding factor?
  • brokensegue 5y ago
    one can imagine factors that would cause both CPU and GPU prices to increase together. for example general purpose computing demand or supply-side constraints might cause all chip prices to rise. if those non-crypto factors were confounding (say also happened to correlate with crypto-prices maybe due to some third unknown factor) then we would see CPU and GPU prices rise in response to crypto prices. we do not see that.

      > for example general purpose computing demand or supply-side constraints might cause all chip prices to rise. This. Those who can't afford anymore powerful video cards now fall back to CPUs with decent integrated graphics, so that the higher than normal demand is therefore affecting their prices too.

      Ok thanks, so it's like saying that we can ignore anything to do with manufacturing?
