Nvidia announced new chips for building and deploying artificial intelligence models at its annual GTC conference on Tuesday.
CEO Jensen Huang revealed Blackwell Ultra, a family of chips shipping in the second half of this year, as well as Vera Rubin, the company’s next-generation graphics processing unit, or GPU, that is expected to ship in 2026.
Nvidia’s sales are up more than sixfold since its business was transformed by the release of OpenAI’s ChatGPT in late 2022. That’s because its “big GPUs” have most of the market for developing advanced AI, a process called training.
Software developers and investors are closely watching the company’s new chips to see if they offer enough additional performance and efficiency to convince the company’s biggest end customers — cloud companies including Microsoft, Google and Amazon — to continue spending billions of dollars to build data centers based around Nvidia chips.
“This last year is where almost the entire world got involved. The computational requirement, the scaling law of AI, is more resilient, and in fact, is hyper-accelerated,” Huang said.
Tuesday’s announcements are also a test of Nvidia’s new annual release cadence. The company is striving to announce new chip families on an every-year basis. Before the AI boom, Nvidia released new chip architectures every other year.
The GTC conference in San Jose, California, is also a show of strength for Nvidia.
The event, Nvidia’s second in-person conference since the pandemic, is expected to have 25,000 attendees and hundreds of companies discussing the ways they use the company’s hardware for AI. That includes Waymo, Microsoft and Ford, among others. General Motors also announced that it will use Nvidia’s service for its next-generation vehicles.
The chip architecture after Rubin will be named after physicist Richard Feynman, Nvidia said on Tuesday, continuing its tradition of naming chip families after scientists. Nvidia’s Feynman chips are expected to be available in 2028, according to a slide displayed by Huang.
Nvidia will also showcase its other products and services at the event.
For example, Nvidia announced new laptops and desktops using its chips, including two AI-focused PCs called DGX Spark and DGX Station that will be able to run large AI models such as Llama or DeepSeek. The company also announced updates to its networking parts for tying hundreds or thousands of GPUs together so they work as one, as well as a software package called Dynamo that helps users get the most out of their chips.

Vera Rubin
Nvidia expects to start shipping systems on its next-generation GPU family in the second half of 2026.
The system has two main components: a CPU, called Vera, and a new GPU design, called Rubin. It’s named after astronomer Vera Rubin.
Vera is Nvidia’s first custom CPU design, the company said, and it’s based on a core design they’ve named Olympus.
Previously when it needed CPUs, Nvidia used an off-the-shelf design from Arm. Companies that have developed custom Arm core designs, such as Qualcomm and Apple, say that they can be more tailored and unlock better performance.
The custom Vera design will be twice as fast as the CPU used in last year’s Grace Blackwell chips, the company said.
When paired with Vera, Rubin can manage 50 petaflops while doing inference, more than double the 20 petaflops for the company’s current Blackwell chips. Rubin can also support as much as 288 gigabytes of fast memory, which is one of the core specs that AI developers watch.
Nvidia is also making a change to what it calls a GPU. Rubin is actually two GPUs, Nvidia said.
The Blackwell GPU, which is currently on the market, is actually two separate chips that were assembled together and made to work as one chip.
Starting with Rubin, Nvidia will say that when it combines two or more dies to make a single chip, it will refer to them as separate GPUs. In the second half of 2027, Nvidia plans to release a “Rubin Next” chip that combines four dies to make a single chip, doubling the speed of Rubin, and it will refer to that as four GPUs.
Nvidia said that will come in a rack called Vera Rubin NVL144. Previous versions of Nvidia’s rack were called NVL72.

Blackwell Ultra
Nvidia also announced new versions of its Blackwell family of chips that it calls Blackwell Ultra.
That chip will be able to produce more tokens per second, which means that the chip can generate more content in the same amount of time as its predecessor, the company said in a briefing.
Nvidia says that means that cloud providers can use Blackwell Ultra to offer a premium AI service for time-sensitive applications, allowing them to make as much as 50 times the revenue from the new chips as the Hopper generation, which shipped in 2023.
Blackwell Ultra will come in a version with two paired to an Nvidia Arm CPU, called GB300, and a version with just the GPU, called B300. It will also come in versions with eight GPUs in a single server blade and a rack version with 72 Blackwell chips.
The top four cloud companies have deployed three times the number of Blackwell chips as Hopper chips, Nvidia said.
DeepSeek
China’s DeepSeek R1 model may have scared Nvidia investors when it was released in January, but Nvidia has embraced the software. The chipmaker will use the model to benchmark several of its new products.
Many AI observers said that DeepSeek’s model, which reportedly required fewer chips than models made in the U.S., threatened Nvidia’s business.
But Huang said earlier this year that DeepSeek was actually a good sign for Nvidia. That’s because DeepSeek uses a process called “reasoning,” which requires more computing power to provide users better answers.
The new Blackwell Ultra chips are better for reasoning models, Nvidia said.
It’s developed its chips to more efficiently do inference, so when new reasoning models require more computing power at the time of deployment, Nvidia’s chips will be able to handle it.
“In the last 2 to 3 years, a major breakthrough happened, a fundamental advance in artificial intelligence happened. We call it agentic AI,” Huang said. “It can reason about how to answer or how to solve a problem.”

Intel snapped a losing streak of six straight quarterly losses and returned to profitability in the third quarter.
In its first earnings report since the Trump administration acquired a 10% stake in the company, the U.S. chipmaker posted strong revenue, noting robust demand for chips that it expects to continue into 2026.
Client computing revenue, which includes chips for PCs and laptops, grew 5% year over year, benefiting from PC market stabilization and artificial intelligence PC prospects.
CEO Lip-Bu Tan said in a call with analysts Thursday that artificial intelligence “is a strong foundation for sustainable long-term growth as we execute.”
The chip strength and demand were bright spots, but there were areas of concern as well, with the company’s foundry business still needing a big break.
Here are three takeaways from the chipmaker’s Q3 report:
Cash flow
“We significantly improved our cash position and liquidity in Q3, a key focus for me since becoming CEO in March,” Tan said on a call with analysts Thursday.
Intel landed an $8.9 billion investment from the U.S. government in August, along with $2 billion from Softbank, but has not yet received the $5 billion tied to a deal with Nvidia. The company expects that deal to close by the end of Q4.
With all of those transactions completed, plus the Altera sale, Intel will have $35 billion in cash on hand, CFO David Zinser told CNBC.
The U.S. government is the company’s biggest shareholder, and Intel stock is up more than 50% since Aug. 22, when Commerce Secretary Howard Lutnick announced the deal.
“Like any shareholder, we have to keep in touch with them,” Zinser said of the U.S. stake. “We don’t tell them how the numbers are going before the quarter. We generally talk to them like Fidelity,” another Intel shareholder.

Foundry
The firm’s foundry remains a work in progress.
Revenue fell 2% over the year before, and it has yet to land a major customer.
Intel now has two fabs running 18A nodes, which are designed for AI and high-performance computing applications.
“We are making steady progress on Intel 18A,” Tan said of its latest chip technology. “We are on track to bring Panther Lake to market this year.”
Zinser said the more advanced 14A nodes won’t be put in supply until the company has “real firm demand.”
Old stuff still selling
Zinser said the company’s older chipmaking processes, or nodes, have continued to do well, “and that was probably the part that was more unexpected.”
Zinser said the chipmaker met some of the central processing unit (CPU) demand with inventory on hand, but they will be behind in Q1, “probably Q2 and maybe in Q3.”
The supply crunch has been with older Intel 10 and 7 manufacturing technologies.
Many customers are opting for less advanced hardware to refresh their operating systems, demonstrating enterprises aren’t waiting for cutting-edge chips when proven technology gets the job done.
