That was a joke 😂 I’m not seriously thinking they put ARM instructions in a x86 processor, though they might’ve tried to replicate the optimisations that led to less power usage in those RISC processors (I still can’t get why RISC CPUs are more power efficient honestly, it seems counter intuitive, now again it might just be because of overengineering).

For your information : the dress is really blue and black, according to the store and manufacturer. The vast majority of people see it as white and gold, but I personally think most people are not used to decrypting overexposed pictures, hence their inability to perceive the right colors.
