Core Viewpoint - ASML's CEO acknowledges that China has developed domestic lithography equipment, indicating that while there is still a long way to go to catch up with ASML's technology, U.S. measures to suppress China may lead to increased efforts from China to succeed [1] Group 1: Chinese Technological Advancements - The Chinese Academy of Sciences has successfully developed a breakthrough solid-state DUV laser capable of emitting coherent light at 193nm, aligning with the mainstream DUV exposure wavelength, which can advance semiconductor processes to 3nm [1][2] - The developed technology achieves an average laser power of 70mW, a frequency of 6kHz, a linewidth of less than 880MHz, and a full width at half maximum (FWHM) of less than 0.11pm, with spectral purity comparable to existing commercial excimer laser systems [1] Group 2: Comparison with ASML Technology - The solid-state DUV light source technology has been published on the International Society for Optics and Photonics (SPIE) website, showing that while spectral purity is nearly on par with commercial standards, output power and frequency are still significantly lower [4] - Compared to ASML's technology, the frequency achieved is about 2/3, but the output power is only at 0.7% level, indicating that further iterations and improvements are necessary for practical application [4]

Core Viewpoint - The article discusses the current market situation of the NVIDIA RTX 5090 graphics card, focusing on its price decline, rental market, computing power, power consumption, performance, heat issues, and networking capabilities. Pricing - The initial market price of the RTX 5090 was over 40,000 yuan, but it has dropped to just over 20,000 yuan within four months, with some brands listed as low as 23,000 yuan. This price decline is attributed to overheating issues, rumors of performance bottlenecks, initial high pricing by manufacturers, and competition from the previous generation RTX 4090 [2]. Rental Market - The high initial price of the RTX 5090 led to slow development in the rental market. As of May, with prices dropping, some data centers began offering RTX 5090 models for rent. The investment payback period for an 8-card machine is approximately four years, which may deter AI companies given the rapidly changing demand for computing power [3]. Computing Power - The RTX 5090 exhibits impressive computing power, particularly in AI training and inference scenarios, with a single card delivering 419 TFLOPS and an 8-card machine achieving around 3.4 PFLOPS. A cluster of 300 RTX 5090 cards can reach PFLOPS-level computing power. The rental price for a single card is about 10,000 yuan per year, while an 8-card machine costs around 300,000 yuan [4]. Power Consumption - The RTX 5090 has a rated power consumption of 575W, with peak consumption reaching up to 900W. An 8-card machine consumes approximately 6kW, leading to monthly electricity costs of about 3,600 yuan based on a rate of 0.6 yuan per kWh. High power consumption increases operational costs and necessitates robust cooling and power supply systems [6]. Performance - In AI inference scenarios, the RTX 5090 supports low-precision calculations (FP8 and FP4), significantly enhancing efficiency. It shows about a 50% improvement in inference speed compared to the previous generation RTX 4090. In gaming, it outperforms the 4090 at 4K resolution, but optimal performance requires targeted optimization [7]. Heat Issues - The RTX 5090 faces heat issues primarily related to the chip and power connectors, particularly the 12V-2x6 connector. Although such problems are infrequent, they require attention. Solutions include limiting peak power through driver or BIOS settings and enhancing cooling systems [8][11]. Networking Capabilities - Initial concerns about potential "lock card" issues in multi-card networking have been largely alleviated. Testing has shown stable performance in NVLink and PCIe networking, making the RTX 5090 suitable for building high-performance AI clusters [10][12].
