A lot of resources on changes in ddr5 only provide "marketing-level" overview of the differences. Yes, it can reach faster clock speeds, reduce energy consumption and have more gb per chip, but what actually makes those things possible? If it is just better manufacturing quality, why can't it be done with ddr4?

I'm mostly interested in what makes higher clocks possible, from what i found out the power consumption reduction is due to integrated power management and higher capacity is command encoding changes, but nothing really explains the clock increase.
