微软用「光」跑AI登上Nature,100倍能效颠覆GPU,华人首席研究员扛鼎
3 6 Ke· 2025-09-15 03:41
过去的几十年,各大公司都在芯片上暗暗较劲:芯片涨价、GPU短缺、AI算力焦虑... 就在大家盯着芯片迭代升级时,微软在悄悄做另一件事:用光重新定义计算。 他们花了四年,用手机摄像头、Micro LED和透镜,拼出了一台模拟光学计算机(AOC)。 如今,这个实验已经登上Nature,带来了一个足以颠覆GPU的未来想象。 光子登场:固定点搜索的秘密 几十年来,算力的故事几乎都写在硅片上:摩尔定律的加速、GPU的堆叠、能耗的焦虑。 可在英国剑桥,微软研究院的一支小团队走了一条完全不同的路——让光来算数。 他们拼出了一台模拟光学计算机(AOC),材料一点也不稀有:Micro LED、光学镜头、还有来自手机的摄像头传感器。 看上去更像是一台实验室「组装机」,却打开了算力的另一种可能。 英国剑桥Microsoft Research实验室模拟光学计算机的详细图像。它是使用市售部件制造的,例如micro-LED灯和智能手机摄像头的传感器 其实,光学计算的设想早在20世纪60年代就被提出过,只是在当时受限于工艺,一直停留在理论层面。 如今,微软团队把它真正做了出来。 AOC真正的秘密不在这些零件,在于它的运行方式——固定点搜索 ...

Summary of Conference Call Notes Industry or Company Involved - The discussion primarily revolves around the Chinese stock market, specifically the Shanghai Composite Index and the ChiNext Index, along with various sectors such as TMT (Technology, Media, and Telecommunications), real estate, and cyclical industries. Core Points and Arguments 1. **Market Status**: The current market is in a systematic bull phase, rebounding from declines since 2015, with a target of at least 4,130 points for the Shanghai Composite Index [1][4][5]. 2. **Index Performance**: The Shanghai Composite Index has completed a four-wave adjustment and is expected to continue its upward trend after a short-term adjustment around 3,700 points [1][5]. The ChiNext Index has recently reached new highs but faces technical resistance [3][6]. 3. **Market Dynamics**: The market is driven by liquidity and investor sentiment, leading to increased volatility and shorter adjustment periods [1][7]. Historical comparisons indicate that rapid adjustments are normal in liquidity-driven bull markets [8]. 4. **Sector Performance**: The TMT sector, particularly the electronics industry, is performing exceptionally well, driven by positive news from Oracle and strong market sentiment [10][14]. The real estate sector is also gaining attention, showing signs of a long-term bottom [15]. 5. **Cyclical Industries**: Cyclical sectors such as steel, non-ferrous metals, and basic chemicals are performing well, while the banking sector has seen the largest declines [16]. 6. **Investment Strategy**: Investors are advised to maintain mid-term positions and consider increasing allocations during market fluctuations, particularly in lower-valued sectors like real estate and infrastructure [24][28]. 7. **Future Market Expectations**: The market is expected to experience further upward movement, with potential fluctuations before reaching the 4,130-point target. The timeline for this movement is estimated to be two to three months [19][18]. Other Important but Possibly Overlooked Content 1. **Technical Analysis**: The 4,100-4,130 range is identified as a significant resistance level based on Fibonacci retracement and trendline analysis [20]. 2. **Market Signals**: Recent strong performances in the ChiNext and the Science and Technology 50 Index are seen as reversal signals, indicating the end of the four-wave adjustment [11]. 3. **Investment Focus**: There is a shift towards soft technology sectors like computing and media, while hard technology stocks are recommended for reduction due to their higher valuations [25][26]. 4. **Brokerage Sector Outlook**: Smaller brokerages are expected to continue their upward trajectory, while larger brokerages have reached historical highs and may not be the focus for new investments [27]. 5. **Overall Market Style**: The current market is characterized by a growth style, with a transition towards cyclical stocks as the economy recovers [29]. This summary encapsulates the key insights and projections from the conference call, providing a comprehensive overview of the current market landscape and investment strategies.

Summary of Conference Call Records Industry or Company Involved - The conference call discusses the performance and outlook of the A-share and Hong Kong stock markets, particularly focusing on the impact of global liquidity, currency fluctuations, and sector performance. Core Points and Arguments 1. **Global Liquidity and Market Performance** Global liquidity easing is beneficial for risk assets, with both Hong Kong and A-shares expected to benefit. The U.S. Treasury's actions, such as increasing short-term debt issuance, may further lower U.S. interest rates, supporting risk asset growth [1][4]. 2. **AH Premium Narrowing** The narrowing of the AH premium is influenced by changes in U.S.-China interest rate differentials and shifts in market expectations regarding China's long-term growth. The AH premium has decreased from 35-40% to below 20% this year [1][5]. 3. **RMB Appreciation and Market Sentiment** The appreciation of the RMB enhances market risk appetite and supports downward space, leading to foreign capital inflows. Historical data shows significant foreign capital inflows during RMB appreciation periods, with passive funds reacting more strongly [1][6]. 4. **Sector Performance in Hong Kong** The technology sector in Hong Kong is poised for a dual boost in valuation and sentiment. Major internet companies are gaining attention for their AI, gaming, and cloud services, despite competitive pressures [1][7]. 5. **Foreign Investment Trends** There is a noticeable increase in foreign interest in Chinese assets, particularly in A-shares and Hong Kong stocks. The inflow of passive funds is outpacing market growth, indicating potential for further allocation increases [1][8]. 6. **Sectoral Benefits from RMB Appreciation** During RMB appreciation, the technology sector leads in performance, while sectors like non-ferrous metals, agriculture, home appliances, and machinery benefit from reduced cost pressures and advantages in overseas markets [1][9][10]. 7. **Investment Recommendations for Hong Kong** Recommendations for Hong Kong investments include a focus on technology, followed by non-bank financials and traditional consumer goods, as these sectors may gain further advantages amid foreign capital inflows and RMB appreciation [1][11]. 8. **Sentiment Indicators for Investment Decisions** Sentiment indicators can objectively measure market participant emotions, providing insights for investment timing. A divergence between personal sentiment and sentiment indicators may signal good entry points [2][12]. 9. **Performance of Overseas Chinese Stocks** The performance of overseas Chinese stocks in the first half of 2025 was stable, with revenue growth around 2% and profit growth around 5%. The financial sector showed slight declines, while non-financial sectors remained robust [1][13][14]. 10. **Sector Highlights in Financial Reports** The technology hardware and new consumption sectors showed strong revenue and profit growth, while the internet and automotive sectors faced challenges but are still in a revenue growth phase [1][15][16]. 11. **Cash Flow and ROE Trends** The cash flow situation for overseas Chinese stocks is improving, with operating cash flow rising and dividend payouts increasing by about 10%. The return on equity (ROE) has slightly improved, driven by net profit margin enhancements [1][18][20]. 12. **Market Dynamics and Future Outlook** The A-share market has shown signs of recovery, with active trading and sector trends becoming more pronounced. The outlook for domestic fundamentals remains positive, with expectations of stabilization in capacity cycles [1][22][23]. 13. **Investment Selection Criteria** Investment selection is based on inventory and capacity cycles, with recommendations for sectors showing signs of recovery and improvement in order trends, such as TMT and high-end manufacturing [1][29]. Other Important but Possibly Overlooked Content - The overall sentiment in the market is influenced by external factors, including U.S. Federal Reserve policies, which are expected to favor growth sectors like pharmaceuticals and technology in Hong Kong [1][25]. - The internal competition in the Hong Kong market is less severe compared to A-shares, providing a more favorable environment for certain sectors [1][19].
