And a lot of datacenter CPUs are also on renewables that are helped by the kind of work done with these halo / flagship consumer products. After all, the power efficiency in datacenters is probably more important in aggregate given they're likely going to go into legacy power grids over time as hyper scalers switch generations (oftentimes due to greater power efficiency).

Some of the engine work done for drag racing cars did make its way into consumer cars and it's not like grandma and grandpa are going to be ever running these high end CPUs either.

Power efficiency gains in recent generations have been pretty incredible - somewhere around 95% aggregate performance with half the aggregate power consumption of these processors is really crazy.
