What actually differs
Both GPUs launched in 2026: the Vera Rubin on Rubin and the Rubin on Rubin.
Dense throughput for the Vera Rubin against the Rubin: FP64 67 vs 33 TFLOPS, FP32 260 vs 130 TFLOPS, FP16 8,000 vs 4,000 TFLOPS, FP8 35,000 vs 17,500 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.
Memory is 576 GB against 288 GB, fed at 44.0 TB/s versus 22.0 TB/s. More memory per GPU means larger models fit before you have to shard across cards, which often matters more than raw TFLOPS for inference.
For LLM training and inference, weight the FP8 and FP16 rows and memory capacity most heavily. For scientific and HPC workloads, the FP64 row is the one to read.
