Context Before

Evidence

To double the scale-up bandwidth using copper interconnect, NVIDIA would have to achieve a per lane bandwidth of 448Gbit/s uni-di (and implemented with simultaneous bi-directional §2§ so that each physical channel carries 448G of RX and 448G of TX).

Context After

② Atomic Claim

若要用 copper interconnect 將 scale-up bandwidth 翻倍，NVIDIA 必須做到每 lane 448Gbit/s uni-di；若採 simultaneous bi-directional，單一 physical channel 需同時承載 448G RX 與 448G TX。
