Nvidia Stocks Rise 1.7% With Rubin Specification Gap Shifting Focus to Workload Tests

Nvidia NVDA has a bandwidth question to answer behind its AI computing ambitions. Shares rose 1.68% to $208.08 at 10:00 a.m. ET on November 2, as Dataconomy’s review highlighted differences between earlier Vera Rubin specifications and the current product table. For investors, the harder test is how much useful work customers get for their money.

Nvidia’s current Vera Rubin NVL72 specifications list memory bandwidth of 19.2 terabytes per second per GPU, versus up to 22 in its July 21 architecture bloga 12.7% difference. Memory capacity remains 288 gigabytes. Per-GPU NVLink bandwidth stands at 3 terabytes per second, compared with 3.6 previously, a 16.7% gap. Those comparisons do not establish equivalent slowdowns in customer workloads, and the November 2 coverage does not establish when the specifications changed.

The GuruFocus snapshot gives Nvidia a GF Score of 96 out of 100, with strong profitability, growth and momentum readings, while valuation is its weakest dimension. That combination suggests business strength may already carry a demanding price tag. The bandwidth differences put more weight on delivered throughput, utilization and cost per token: those measures could show whether customers still earn compelling returns from the hardware.
