[r/LocalLLaMA] NVIDIA admits to only 2x performance boost at max throughput with new generation of Rubin GPUs

Summary

NVIDIA's new Rubin GPUs are reported to offer only a 2x performance boost at max throughput compared to the B200 generation, despite significant increases in memory bandwidth and FP4 performance. This modest gain comes with a substantial efficiency trade-off, as the Rubin R200 consumes 2.3 times more power for just double the performance. This revelation suggests a less compelling upgrade path for companies prioritizing production throughput and power efficiency.
