看到有人猜 nv为了合格率，把16GB阉割成14GB。

看样子H100 PCIe 贴了6块显存，96G，只有给用户80GB用。

NVL是，给了80GB，再多给你14GB。实际上上少割了，推销成 多给14GB。确实 厉害的 皮夹克 。

Even then, it should be noted that customers aren’t getting access to quite all 96GB per card. Rather, at a total capacity of 188GB of memory, they’re getting effectively 94GB per card. NVIDIA hasn’t gone into detail on this design quirk in our pre-briefing ahead of today’s keynote, but we suspect this is also for yield reasons, giving NVIDIA some slack to disable bad cells (or layers) within the HBM3 memory stacks. The net result is that the new SKU offers 14GB more memory per GH100 GPU, a 17.5% memory increase. Meanwhile the aggregate memory bandwidth for the card stands at 7.8TB/second, which works out to 3.9TB/second for the individual boards.
