In terms of news, it was reported that Google is developing a new server chip codenamed "Frozen v2," aimed at significantly improving the operational efficiency of the Gemini model. This chip directly solidifies part of Gemini's underlying architecture into silicon, achieving a leap in energy efficiency by reducing real-time computation and data movement. It is understood that compared to the latest generation of TPUs, Frozen v2 is expected to process 6 to 10 times more tokens per unit of power consumption, effectively alleviating the shortage of computing power.

A research report from Dongguan Securities points out that on the demand side, AI training, inference, and intelligent agent applications continue to scale up, while overseas cloud providers' CAPEX remains upwardly revised, driving high prosperity in computing infrastructure construction and continuously boosting demand for storage, CPUs, power semiconductors, semiconductor materials, and other segments. Some niche categories have already seen tight supply and rising prices. On the supply side, key links such as semiconductor equipment, high-end GPUs, memory chips, and advanced packaging are still in an accelerated stage of domestic substitution, strengthening the demand for industrial chain autonomy and controllability. Looking ahead to the second half of the year, AI demand remains the core driver of the semiconductor industry's upward prosperity.
