I'm not so sure there. The factor of 72 is accidentially also the number of GPUs in a full GB200 DGX rack[0]. The phrasing "and it reaches 72,000 TPS/server at our highest throughput configuration" also hints at something being fishy here. They carefully use the phrases "node" earlier, and "server" later, without getting specific by what they mean a "server" to be. Also, for that 72000 figure, there is no mention of batching at all.
The very short article [2] linked in [0] which is supposed to be the independent source of those numbers also doesn't specify any details to that effect.
In general, I've learned to treat Nvidia numbers very carefully. They are well-known for misrepresenting apples-to-orange-elefants figures such as comparing FP16, FP8 or FP4 FLOPS, thereby grossly overstating the performance advantages of their new architectures[3].

- supermatt 1y ago> The factor of 72 is accidentially also the number of GPUs in a full GB200 DGX rack Sure, but in the article it is already mentioned as 1000 TPS/User for an 8 GPU node, and the rack contains 9 nodes - i.e. 9x more GPUs, not 72x - so the 72000 TPS/Server simply being a multiple of 72 seems like a red herring. But yeah, I agree that 72x seems high - although only 9x seems low given vLLM showing over 20x speedups with continuous batching. I guess there are a lot of variables.
