Evidence
All current evidence in the supply chain points to NVSwitch 7 being the same bandwidth as NVSwitch 6, but that is seems a bit illogical to be frank. Our belief is that NVSwitch 7 is actually 2x the bandwidth and radix of NVSwitch 6, so all-to-all can be done, and architecturally that makes the most sense from a systems perspective.
Context After
Rubin Ultra NVL576
To push the scale up world size beyond 144 GPUs and across multiple racks, optics are needed as we are approaching the maximum compute density that is within the reach of copper. Rubin Ultra NVL576 is now on the roadmap with 8 racks of lower density Oberon.
② Atomic Claim
SemiAnalysis reports that current supply-chain evidence points to NVSwitch 7 having the same bandwidth as NVSwitch 6, while separately stating an inference that it may double.
