I'd say this graph is absolute rubbish. The fact that the numbers are round numbers, decreasing in even steps, with no units, no comparison, incorrect scaling, and incorrect layout for a graph, suggests that this is little more than fanfiction. The truth is that the hyperscalers are very closely guarding information around things like this. Who has the biggest "cluster" is impossible to answer. Also most hyperscalers will have many clusters, and what's more useful, the SUM or MAX of those clusters? At a small scale probably the MAX, but at a large scale the SUM because you can distribute across clusters without as much loss in overheads and because you have a range of jobs to run.
