No, it says it is 13 times faster, and 10x more power efficient. So you could train a model 10 times bigger for the same power usage (assuming it scales linear

No, it says it is 13 times faster, and 10x more power efficient. So you could train a model 10 times bigger for the same power usage (assuming it scales linearly), and it would be a bit faster to do that as well. Or you could train a model 13 times bigger for the same speed, and use 10x less power than if you hadn't.
