Except heat doesn't cooperate
- hannasanarion 7y agoBrains have the benefit of an elaborate microscopic network of coolant pipes that double for power delivery
- ChuckMcM 7y agoExactly, and I've kept an eye on Nature Materials and other journals that cover advances in semiconductor cooling but so far there hasn't been anything very exciting. I was hoping the ultra thin silicon guys would use diamond as a substrate for its thermal properties (sort of like silicon on sapphire but silicon on diamond instead) but apparently not a thing yet.

- zeusk 7y agopower and frequency are linearly related, it is the voltage that scales power in a quadratic order.
