The RTX 3090 supports NVLink bridging, and two cards via NVLink can achieve higher interconnect bandwidth, which is often more balanced than a three-card PCIe setup for quantized inference of 70B-class models.

UnverifiedNVLink's bandwidth is far lower than the intra-card bandwidth of a single GPU, and cross-card communication creates a bottleneck.72% similarUnverifiedNVLink speed degradation or fallback to PCIe mode can reduce intra-node communication speed by several times, yet OS-level health checks will still mark the link as normal.66% similar
