PsiQuantum announced an 8x8 optical circuit switch using low-loss silicon photonics that loses only 1.2 dB of signal.
Nvidia GeForce RTX 5080 prices have reached $2,000, matching the RTX 5090's launch price, with some listings exceeding $2,900. The cheapest in-stock unit from Best Buy is a PNY RTX 5080 at $1,999, while third-party sellers like Empowered PC on Amazon list similar cards for $2,211.17. Stock is scarce, limited mostly to online third-party sellers or local pickup at Micro Center. This surge marks the first time the RTX 5080's price floor hits the RTX 5090's launch MSRP of $1,999, a significant rise from its average $1,500 price in August. The RTX 5090 itself now sells for up to $12,000. This pricing occurs because Nvidia shifted focus to the enterprise market and memory manufacturers redirected DRAM production to HBM for AI data centers, reducing supply for consumer GPUs despite the RTX 5080 featuring 10,752 CUDA cores and 16GB of GDDR7 VRAM.

▸중국 산업설비 수출 급증…"한국, 품질·납기·유지보수로 맞서야"China's Industrial Equipment Exports Surge: "Korea Must Compete on Quality, Delivery, and Maintenance"연합뉴스 (Yonhap, 경제) · yesterday
The Korea International Trade Association's International Trade and Investment Research Institute argues that Korea must counter China's rising industrial equipment exports by emphasizing quality, delivery reliability, and maintenance in advanced markets, while targeting production process upgrades in emerging markets. The institute cites a report stating China's industrial equipment exports are projected to rise from $14.2 billion in 2015 to $257.2 billion in 2025, a 2.5-fold increase averaging 8.2% annually. Evidence shows China surpassed Germany in logistics equipment and joined Germany as a top global supplier of general equipment. While China's share in emerging markets grew from 21.1% to 29.6%, its advanced market share only rose slightly to 14.0% due to U.S. sanctions. Researcher Hesselbi notes that while Korea maintained a stable 3.3% share in advanced markets, its emerging market share fell from 6.3% to 4.1% due to China's low-price strategy.

Today's digest, illustrated

A surreal editorial illustration blending a high-tech server room with a war-torn landscape, where glowing green photonics switches and floating AI neural networks drift above crumbling concrete ruins and rusted missile silos, illuminated by the stark, cold light of server racks and the distant, ominous glow of a North Korean cyber-attack interface, rendered in a gritty, high-contrast style that merges digital abstraction with raw geopolitical tension.
