U.S. chip design firm Advanced Micro Devices on Tuesday unveiled new processors to power artificial intelligence-enabled PCs as it seeks to gain leadership in the AI PC race against rivals like Nvidia and Intel.

AI PCs are personal computers equipped with processors designed to perform AI tasks, such as real-time language translation and summarization.

Referring to them as the most powerful chips yet for business PCs, AMD said the Ryzen Pro 8040 series processors for laptops and the Ryzen Pro 8000 series processors for desktops are built with the advanced 4-nanometer technology.

These processors are expected to power PC models from brands including HP and Lenovo from the second quarter of 2024, AMD said in a press release Tuesday.

These new AMD chips will compete against Nvidia’s and Intel’s chips that are specifically designed for AI PCs.

Like Nvidia, AMD doesn’t fabricate its own chips. Instead, it outsources the manufacturing of its chips to semiconductor foundries, mainly to the world’s largest contract chipmaker Taiwan Semiconductor Manufacturing Company.

TSMC currently produces 3-nanometer chips and plans to commence mass production of 2-nanometer chips in 2025. Typically, a smaller nanometer size yields more powerful and efficient chips. 

In January, AMD announced the next-generation Ryzen 8000G series desktop processors which are able to provide “immense power and dominant performance for intensive workloads including gaming and content creation.” The 8000G series is built on the 4-nanometer process.

AMD and Intel have talked up AI PCs as a new era for the industry. Last year saw an AI boom after ChatGPT’s launch in November 2022.

U.S. consulting firm Gartner estimates shipments of AI PCs will consist of 22% of all PCs in 2024. The research firm expects 54.5 million units of AI PCs to be shipped by the end of the year.

“The rapid adoption of on-device GenAI capabilities and AI processors will eventually become a standard requirement for technology vendors,” said Ranjit Atwal, senior director analyst at Gartner.

However, this could present challenges to vendors as they would face difficulties “differentiating themselves from competitors” and increasing revenue, said Atwal.

Tesla’s stock erases loss for the year, soaring 85% from April low

Tesla's stock erases loss for the year, soaring 85% from April low

Tesla’s shares have finally turned positive for the year.

After a dismal first quarter, which was the worst for the stock in any period since 2022, and a brutal start to April, following President Donald Trump’s announcement of sweeping new tariffs, Wall Street has again rallied around the electric vehicle maker.

The stock rose 3.6% on Monday to $410.26, topping its closing price of 2024 by over $6. It’s up 85% since bottoming for the year at $221.86 on April 4. A new filing revealed that CEO Elon Musk purchased about $1 billion worth of shares in the company through his family foundation.

It’s the second straight year Tesla has bounced back after a down first quarter. Last year, the shares fell 29% in the first three months before ending up 63% for 2024.

In recent weeks, analysts have praised the EV maker’s proposed pay plan for Musk, which could amount to a $1 trillion windfall for the world’s richest person over the next decade. The company has also gotten a boost from its new MegaBlocks battery energy storage systems that Tesla ships preassembled to businesses looking to lower their power costs or make greater use of electricity from renewable resources.

Even with the rebound, Tesla is the second-worst performer this year among tech’s megacaps, ahead of only Apple, which is down about 5% in 2025. Tesla is still in the midst of a multi-quarter sales slump due to an aging lineup of EVs and increased competition from lower-cost competitors in China, namely BYD.

Tesla has seen a consumer backlash, in part because of Musk’s political activities, including spending nearly $300 million to propel President Trump back to the White House and his work with the Trump administration to slash the federal workforce.

Tesla leadership has been working to shift investors’ attention to other topics such as robotaxis and humanoid robots.

However, the company has yet to deliver vehicles that are safe to use without a human onboard and ready to take control if needed. And while Musk is touting Tesla’s Optimus robots, which he says will be able to do everything from factory work to babysitting, a product is still a long way from hitting the market.

Alphabet becomes fourth company to reach $3 trillion market cap

Alphabet becomes fourth company to reach  trillion market cap

Alphabet has joined the $3 trillion club.

Shares of the search giant jumped more than 4% on Monday, pushing the company into territory occupied only by Nvidia, Microsoft and Apple.

The stock got a big lift in early September from an antitrust ruling by a judge, whose penalties came in lighter than shareholders feared. The U.S. Department of Justice wanted Google to be forced to divest its Chrome browser, and last year a district court ruled that the company held an illegal monopoly in search and related advertising.

But Judge Amit Mehta decided against the most severe consequences proposed by the DOJ, which sent shares soaring to a record. After the big rally, President Donald Trump congratulated the company and called it “a very good day.”

Alphabet shares are now up more than 30% this year, compared to the 15% gain for the Nasdaq.

The $3 trillion milestone comes roughly 20 years after Google’s IPO and a little more than 10 years after the creation of Alphabet as a holding company, with Google its prime subsidiary.

CEO Sundar Pichai was named CEO of Alphabet in 2019, replacing co-founder Larry Page. Pichai’s latest challenge has been the surge of new competition due to the rise of artificial intelligence, which the company has had to manage through while also fending off an aggressive set of regulators in the U.S. and Europe.

The rise of Perplexity and OpenAI ended up helping Google land the recent favorable antitrust ruling. The company’s hopes of becoming a major AI player largely ride with Gemini, Google’s flagship suite of AI models.

Bessent: TikTok deal 'framework' reached with China, Trump and Xi will finalize it Friday

The U.S. and China have reached a ‘framework’ deal for social media platform TikTok, Treasury Secretary Scott Bessent said Monday.

“It’s between two private parties, but the commercial terms have been agreed upon,” he said from U.S.-China talks in Madrid.

Both President Donald Trump and Chinese President Xi Jinping will meet Friday to discuss the terms. Trump also said in a Truth Social post Monday that a deal was reached “on a ‘certain’ company that young people in our Country very much wanted to save.”

Bessent indicated that the framework could pivot the platform to U.S.-controlled ownership.

TikTok did not immediately respond to a request for comment.

The comments came during the latest round of trade discussions between the U.S. and China. Relations have soured between the two countries in recent months from Trump’s tariffs and other trade restrictions.

At the same time, TikTok parent company ByteDance faces a Sept. 17 deadline to divest the platform’s U.S. business or face being shut down in the country.

U.S. Trade Representative Jamieson Greer said Monday that the deadline may need to be pushed back to get the deal signed, but there won’t be ongoing extensions.

Congress passed a law last year prohibiting app store operators like Apple and Google from distributing TikTok in the U.S. due to its “foreign adversary-controlled application” status.

But Trump postponed the shutdown in January, signing an executive order in January that gave ByteDance 75 more days to make a deal. Further extensions came by way of executive orders in April and in June.

Commerce Secretary Howard Lutnick said in July that TikTok would shutter for Americans if China doesn’t give the U.S. more autonomy over the popular short-form video app.

As for who controls the platform, Trump told Fox News in June that he had a group of “very wealthy people” ready to buy the app and could reveal their identities in two weeks. The reveal never came.

He has previously said he’d be open to Oracle Chairman Larry Ellison or Tesla CEO Elon Musk buying TikTok in the U.S. Artificial intelligence startup Perplexity has submitted a bid for an acquisition, as has businessman Frank McCourt’s Project Liberty internet advocacy group, CNBC reported in January.

Trump told CNBC in an interview last year that he believed the platform was a national security threat, although the White House started a TikTok account in August.
