This marks a dramatic departure from Buffett's traditionally cautious approach to technology stocks and signals that the post-Buffett era will embrace AI investments.

   Broadcom and Marvell stocks hit record highs as custom AI chip demand surges

   Broadcom and Marvell Technology, companies that make specialized AI chips (custom processors designed for specific AI tasks), reached 52-week high stock prices on Tuesday. Investor Gary Black says these companies are becoming the "big winners" as businesses move away from general-purpose graphics cards to chips built specifically for their AI needs.

   Companies are increasingly choosing specialized AI hardware over one-size-fits-all solutions, which could lead to more efficient and cheaper AI services for consumers and businesses.

   Nvidia expands beyond graphics cards with new AI chips for PCs and data centers

   Nvidia announced two new products: RTX Spark superchips for Windows computers that bring AI capabilities directly to personal devices, and Vera CPUs for data centers. The RTX Spark chips are being developed with Microsoft and MediaTek to enable "agentic AI" (AI that can act independently to complete tasks) on regular computers.

   Future Windows PCs may be able to run sophisticated AI assistants locally without internet connections, making AI features faster and more private for everyday users.

   Nvidia CEO Jensen Huang highlighted a shift from copper wires to optical fiber connections in AI data centers, citing physical limits of copper for high-speed data transfer. Nvidia has committed significant investment to companies like Lumentum Holdings that make optical networking equipment (fiber optic systems that use light to transmit data).

   This infrastructure upgrade could enable faster AI services and reduce delays when using cloud-based AI applications like ChatGPT or image generators.
