Report Summary 1. Report Industry Investment Rating - The rating for the global economy in the macro and financial sector is (Bullish) [1] 2. Core View of the Report - The report presents a series of global economic and financial news and analyzes their potential impacts. It shows that although there are certain risks in the global economic situation, such as the escalating Japanese debt crisis and potential trade disputes, there are also positive factors, including the resilience of China's exports and the improvement of domestic demand, the strong performance of the US economy, and the expansion of the European economy. 3. Summary by Relevant Catalog Important Information - The Japanese debt crisis has escalated, with the 10 - year yield approaching 1.6%, the highest since 2008. Market concerns about a change in fiscal policy may trigger a "bond vigilante" sell - off [1] - UK retail sales in June increased 3.1% year - on - year, exceeding the 1% growth in May and setting the second - largest monthly increase this year [1] - Meta has launched two giant AI clusters, Prometheus and Hyperion, to break through the computing power bottleneck. Prometheus has a scale of up to 1 GW [1] - A well - known asset management institution believes that the investment opportunity in emerging market bonds is "once - in - a - generation" [1] - Citi believes that China's exports in June showed resilience, and imports had their first year - on - year positive growth, reflecting improved domestic demand [1] - The EU is formulating a retaliatory plan and will propose a new tariff list covering about 72 billion euros of US imports [1] - Trump said that if the Russia - Ukraine conflict is not resolved within 50 days, the US will impose "very severe, about 100%" tariffs on Russia [1] Global Economic Logic - China's GDP grew 5.3% in the first half of the year.

Core Viewpoint - NVIDIA has officially launched two CPO (Co-Packaged Optics) switch products, Quantum-X Photonics for InfiniBand and Spectrum-X Photonics for Ethernet, with the InfiniBand CPO expected to debut in the second half of 2025 and the Ethernet CPO in the second half of 2026 [1][2]. Group 1: CPO Technology and Market Position - CPO will be an optional configuration, and NVIDIA will continue to offer traditional switch systems with pluggable modules [2]. - The primary driver for NVIDIA's investment in CPO technology is power optimization, with a significant reduction in power consumption from 30W to 9W for a 1.6T port, achieving a 70% decrease [2]. - NVIDIA's CPO solution utilizes new micro-ring modulators (MRM) for enhanced energy efficiency, contrasting with Broadcom's CPO solution that achieved a 50% power reduction using traditional Mach-Zehnder modulators (MZM) [2]. Group 2: Ecosystem and Partnerships - The technology involves a multi-component ecosystem, integrating electronic and photonic chips through 3D stacking, with TSMC's compact optical engine technology playing a key role [3]. - NVIDIA's CPO partners include major industry players such as Browave, Coherent, Corning, Fabrinet, Foxconn, Lumentum, Senko, SPIL, Sumitomo, Tianfu Communication, and TSMC [3]. Group 3: Strategic Implications and Future Developments - LightCounting notes that NVIDIA's first CPO product is an InfiniBand switch, which has been overshadowed by Ethernet in NVIDIA's AI strategy, indicating that the initial deployment will primarily serve NVIDIA's own clusters [4]. - The Spectrum-X platform aims to elevate Ethernet performance to match that of InfiniBand, with potential for significant GPU interconnectivity in future architectures [4]. - NVIDIA's entry into the CPO market is expected to invigorate the ecosystem, with both NVIDIA and Broadcom projected to release single-channel 200G CPO switches by 2027, leading to a more mature industry landscape [4]. Group 4: Technical Challenges and Innovations - Scale-out is seen as a low-risk entry point for CPO, while scale-up is critical for success, particularly for the mixed expert (MoE) model requiring rapid response times across GPUs [5]. - NVIDIA has previously announced fiber-based NVLink plans, with at least one cluster built internally, but large-scale deployment has been hindered by high power consumption of timing modules [6]. - The NVLink CPO is scheduled for 2028, allowing NVIDIA to validate technology feasibility over two product cycles, significantly reducing future integration risks [6].
