英伟达(NVDA.US)积极反击AI泡沫论：GPU全面领先谷歌TPU “大空头”Burry计算错误

Core Viewpoint - Nvidia is facing renewed scrutiny regarding its AI valuation and potential bubble, prompted by significant shareholder sell-offs and questions about its accounting practices. In response, the company has issued a detailed internal memo addressing at least twelve key allegations from critics, including prominent figures like Michael Burry [1][2]. Group 1: Shareholder Concerns and Accounting Practices - Nvidia's internal memo counters Michael Burry's claims regarding stock buybacks, clarifying that the actual buyback amount since 2018 is $91 billion, not the $112.5 billion Burry cited, which included miscalculated RSU tax payments [1]. - The company firmly denies comparisons to historical accounting fraud cases like Enron and WorldCom, asserting that its business fundamentals are strong and its financial reporting is transparent and complete [1]. Group 2: Depreciation and Competition - Nvidia addresses concerns about long customer depreciation periods, stating that its customers typically depreciate GPUs over 4 to 6 years, reflecting actual equipment lifespan and utilization. The A100 chip, released in 2020, continues to operate at high utilization rates and will generate significant economic value beyond 2 to 3 years [2]. - The company is also responding to competitive pressures from Google's self-developed TPU chips, emphasizing that its GPUs outperform Google's ASIC chips in versatility, flexibility, and performance. Nvidia maintains that its platform is the only solution capable of running all AI models across various environments [2]. Group 3: Market Position and Future Outlook - Despite the competitive landscape, analysts believe Nvidia retains over 90% of the global AI chip market share, with short-term challenges primarily related to market sentiment and valuation fluctuations [3]. - Nvidia's CEO Jensen Huang acknowledges the competition from TPUs and maintains communication with Google DeepMind's CEO, emphasizing that the theory of "scaling laws" supports ongoing demand for high-performance GPUs and systems, which underpins Nvidia's long-term growth prospects [3].
