The article title appears incorrect.
Looking at the table in the article, it’s only be 10-15% more performant (not “30%”) for the same power used.
The “30%” is how much more energy efficient it would be at the old performance (23%-30%).
- Waterluvian 4y agoI don’t understand these things well but in a way, doesn’t that mean I can get 30% more CPUs running for my power usage? I guess in a lot of cases that doesn’t exactly help.
- tiffanyh 4y agoNo. The table says, if you maintain the same power usage you’d get a 10-15% more performance. If you maintain the same performance, you save 23-30% power previously used.
- toast0 4y agoBut also kind of yes. If you've got a fixed power budget, and you replace your old cpus with new ones, running at the same performance, now you're using 23-30% less power use (ignoring non-cpu power budget), and you can bring that many more cpus online at the old performance target.
- torginus 4y agoFor multicore CPUs or GPUs, 30% lower power means, you get 30% more performance at the same power.
