I'm not really in the space - I was curious. I think people tend to overstate the importance of power consumption relative to the price of the products they buy and the value of their time (eg. if it's a workstation part, higher performance is worth a significant tradeoff in power if it gets jobs like compilation done 10% faster based on the employee time it can save)

For servers, I'm always curious because even though they run 24/365 (so power consumption is v.important), the capital cost of new server chips is incredibly high - eg. those 144c chips I presume you're referring to cost 10k+, so even over a 5y service life that's probably only 20% of the chip only, and relative to the AMD chip the additional inefficiency could easily by compensated by an appropriate discount.

Obviously all of this is why intel still exists in the DC, they just can't charge the same prices as AMD can is all.

With great power comes great heat output. Lower power = lower heat output = lower bill for cooling. or the same bill at more capacity = more margin = more profit for the cloud providers :) Or the other thing to consider is, less power usage on a global scale = less co2 output.
