On the news front, after NVIDIA announced multiple technological breakthroughs at the GTC conference, the computing power industry chain experienced a significant decline. According to First Financial, some analysts believe that NVIDIA's announcement of some new generation chips, set to be launched in 2028, has caused disruption in the short-term market sentiment. Although the iteration of related optical communication technology is a long-term positive, for funds seeking certainty, the impact of this positive news on the industry chain's future growth is still unknown, coupled with the industry chain's high valuation and significant previous gains, leading to significant short-term downward pressure. Of note, at the GTC 2026 conference, Huang Renxun stated that "copper is still important, and optics will be used for expansion in different dimensions, both of which are essential capabilities." It is reported that in order to break through capacity constraints, NVIDIA will launch a new MGX chassis - NVIDIA Kyber. NVIDIA Kyber is a new generation MGX NVLink chassis, with the capacity of each NVLink domain in the chassis doubled, capable of accommodating 144 GPUs. Huang Renxun stated that this chassis will use CPO and copper interconnects for expansion (Scale-up). In addition, the Rubin architecture is also expected to adopt copper interconnects on a large scale.
