Rubin Inference Up 5x, But Bandwidth Remains a Bottleneck
Beth_Kindig · x · 2026-07-11
NVIDIA Rubin's inference processing capability is reportedly 5x higher than Blackwell, but HBM bandwidth only increases by 2.8x, meaning the "memory wall" persists.
The author notes that as hyperscalers transition from "building AI" to "monetizing AI," utilizing memory more efficiently becomes crucial. The article focuses on why offload engines will become a key solution for boosting tokens per watt.
