Analysis
A memory shelf can be full while the loading dock sets the pace. NVIDIA’s November fifth technical post describes high bandwidth memory as the fastest, most expensive and most contested tier, where redundant weights or idle context take space from active work. The full article was not read; this account uses the publisher feed excerpt and a separate NVIDIA technical post.
That post describes five levers in NVIDIA’s stack: a smaller number format for weights and cache, spreading experts across eight or more graphics processors, routing cached context across memory tiers, staging idle cache near the graphics processors, and shared storage for reused context. These are NVIDIA’s descriptions of its own system.
The company reports up to thirty times the throughput per megawatt of GB300 NVL72 on SemiAnalysis AgentX, using the same 288 gigabytes of memory per graphics processor. The post specifies coding-agent sessions and a target of 160 tokens per second per user. Change workload, concurrency or interactivity target, and the result may change too.
For an operations team, the useful question is what the setup needs on an ordinary day: power, cooling, software and someone to manage cache misses. The post does not establish costs or results on other workloads. Test one condition at a time on your own workload and target device before building a budget around the headline.

Why it matters
Treat the throughput figure as a vendor benchmark tied to a particular workload and response target; your own workload needs its own measurement.
