I couldn’t find precise information on what bandwidth you’d get with NVLink on the 3090. To be fair, though, if all we do is inference, using Huggingface pipeline parallelism, the amount of data transferred is pretty small: 8192×2×n_tokens bytes; for most uses, with a recent PCIe setup, that bottleneck will take less than 0.1 ms per token generated, which may not be the dominant latency. (Also, the RTX 3090 has faster VRAM, >900 GB/s, than the A6000, because it is GDDR6X.)
