vLLM says Rubin GPUs run its Blackwell kernels unmodified
AIvLLM says a Rubin GPU has 3.5x the FP4 FLOPS, about 2.4x the HBM bandwidth, and 1.7x the NVLink bandwidth of a GB200. The faster NVLink lowers the cost of AllReduce and all-to-all operations in MoE serving. vLLM's Blackwell kernels run on Rubin unmodified, and FlashInfer 0.7.0 adds Rubin-tuned attention, GEMM, and MoE kernels.
