Re:Intel 10nm Chip Gets Mixed Reviews

Why would you say that the lower frequency would be better for thermals and power consumption? It would only be better than the same chip at a higher clock rate. If Intel could increase the clock and maintain the power consumption that's what they would do. From that it follows that these chips consume more power at a lower clock rate.

Because transistors have a capacitance that one has to drive, higher frequency requires more voltage and more voltage means bigger leakage currents which means more heat and power consumption.
Good question, that was just an assumption. I thought that the improved manufacturing process would limit power consumption and was the reason for the decreased clock. But yeah, there could be completely different reasons for that.
