Shares of both Ultra Semiconductor (AMD) and Nvidia (Nvidia) hit record highs on Thursday, thanks to investors' continued buying of shares in artificial intelligence chipmakers.。AMD shares rose more than 1% in Thursday trading to close at an all-time high of 162.$67, while Nvidia rose nearly 2% to 571.07 USD。The two companies posted explosive triple-digit percentage gains in 2023, with AMD shares up 127 percent..6%, Nvidia shares soared 238.8%。

This reflects the continued interest and demand from investors in companies that design and sell graphics processors for artificial intelligence.。GPUs were originally designed for gaming, but they were just as crucial to training and deploying complex AI models, driving a huge jump in chip sales.。

Nvidia has been a major GPU supplier to AI companies and was the best performing stock in the S & P 500 last year.。

AMD, the second-largest independent GPU maker, announced a new chip last year to compete with Nvidia's H100, which is currently the standard for AI applications.。

According to analysts, AMD is improving its AI software, eliminating a major reason why Nvidia chips are superior to AMD.。

In addition, TSMC, which manufactures mostly Nvidia and AMD chips for contract manufacturing, disclosed better-than-expected sales results.。TSMC management believes that manufacturing AI chips could account for "tens of percentage points" of its revenue over the next five years, which has a positive impact on both Nvidia and AMD.。In addition, MetaCEO Zuckerberg also announced plans to buy billions of dollars worth of Nvidia and other GPUs this year.。
