Do you mean this supercomputer has slower internode links? What are its links? For example, xAI just brought up 100k GPU cluster, most likely with 800Gbps internode links, or maybe even double that.
I think the main difference is in the target numerical precision: supercomputers such as this one focus on maximizing FP64 throughput, while GPU clusters used by OpenAI or xAI want to compute in 16 or even 8 bit precision (BF16 or FP8).
