- jhasse 9y ago> so they look for performance per Watt. This was not addressed in the article. The did test power consumption though: https://images.idgesg.net/images/article/2017/09/fnw_showdown_power_scaling-100736973-orig.jpg https://images.idgesg.net/images/article/2017/09/fnw_showdow...
- fpoling 9y agoThat plot shows the power consumption during one rather synthetic benchmark. What is necessary for meaningful conclusion about price/watt is to have power consumption during a particular benchmark so the results can be scaled. This is not addressed.
- jsjohnst 9y agoThey actually did address it tangentially in the article. The highest the AMD CPU used wattage wise was under 275W. They showed Intel using over 50W more at peak and claimed they’d heard of it pulling over 500W (total, and in a scenario that almost no DC would likely do). So yes, AMD has a significant advantage OpEx and CapEx wise.
- nspattak 9y agoto be fair though, these are not server processors, they belong in the office not in a data center.

- jdietrich 9y agoThreadripper is segmented as a workstation processor - Epyc is the server line. Real-world energy efficiency is extremely complex, because it's hugely dependent on workload. If you're the kind of customer that is highly sensitive to efficiency, you really need to perform your own evaluation.
