You're misreading it, there's two different runs, a low and a high compute run.

The number for the high-compute one is ~172x the first one according to the article so ~=$2900

What's extra confusing is that in the graph the runs are called low compute and high compute. In the table they're called high efficient and low efficiency. So the high and low got swapped.
