Artificial-intelligence semiconductor powerhouse Nvidia on Monday unveiled a flagship AI chip, the Blackwell B200, saying it is up to 30 times speedier than its previous chip.

Chief Executive Jensen Huang, kicking off the company’s annual developer conference, also launched a new set of software tools designed to help developers sell their artificial-intelligence models more easily to any company that uses Nvidia.

Nvidia’s chip and software announcements at GTC 2024 will help determine whether the company can maintain its leadership position as the dominant seller of AI equipment. Nvidia had a roughly 80% share of the data center AI chip market last year.

“I hope you realize this is not a concert,” Huang, wearing his trademark black leather jacket, said after taking the stage, in a nod to the rising profile of his company.

The B200 takes two chips the size of Nvidia’s previous offering and binds them together into a single chip.

The new chip has 208 billion transistors, more than double the 80 billion on the company’s previous chip. All of those transistors can access the memory attached to the chip at nearly the same time, improving productivity.

Tom Plumb, CEO and portfolio manager at Plumb Funds, which has Nvidia as one of its largest holdings, said the Blackwell chip was not a surprise.

“But it reinforces that this company is still at the cutting edge and the leader in all graphics processing. That doesn’t mean the market is not going to be big enough for AMD and others to come in. But it shows that their lead is pretty insurmountable,” said Plumb.

Insider Intelligence analyst Jacob Bourne said Nvidia could solidify its AI dominance. “However, rivals like AMD, Intel, startups, and even Big Tech’s own chip aspirations threaten to chip away at Nvidia’s market share, particularly among cost-conscious enterprise customers,” he said.

Nvidia said major customers, including Amazon, Alphabet’s Google, Meta Platforms, Microsoft, OpenAI, Oracle and Tesla, are expected to use the new chip.

Nvidia also is shifting from selling single chips to selling total systems. Its latest iteration houses 72 of its AI chips, 36 central processors and contains 600,000 parts and weighs 3,000 pounds.

Though Nvidia is widely regarded as a chip designer, the company has built a significant battery of software products as well.

The new software tools, called microservices, improve system efficiency across a wide variety of uses, making it easier for a business to incorporate an AI model into its work, just as a good computer operating system can help apps work well.

Nvidia’s shares have surged 240% over the past 12 months, making Nvidia the US stock market’s third-most valuable company, behind only Microsoft and Apple.

Nvidia stock dipped 1% in extended trade on Monday, while Super Micro Computer, which makes AI-optimized servers with Nvidia’s chips, fell 4%. Advanced Micro Devices stock dipped nearly 3% during Huang’s keynote address.

Its stellar 12-month rally leaves Nvidia’s stock at risk of plummeting back to earth if the Santa Clara, Calif., company fails to expand its AI business as much as investors expect.

Nvidia’s market share is expected to drop several percentage points in 2024 as new products from rivals such as Intel and Advanced Micro Devices hit the market.

Huang spoke at a Silicon Valley hockey arena to accommodate its largest crowd for its annual conference.

Huang also announced partnerships with design software companies Ansys, Cadence and Synopsys. Shares of the three companies jumped around 3% in extended trade following Huang’s comments.

Trump 'very disappointed' in Russian strikes on Ukraine and calls for Putin to 'sit down and sign a deal'

Donald Trump has said he’s “very disappointed” with Russia as he continues to push for a peace deal to end the war in Ukraine.

On Saturday, the US president met with Volodymyr Zelenskyy at the Vatican for their first face-to-face meeting since their explosive White House summit.

The Ukrainian president said the meeting ahead of Pope Francis’s funeral could end up being “historic.” Hours later, Mr Trump questioned Vladimir Putin’s appetite for peace in a Truth Social post.

From Saturday: Trump meets Zelenskyy at funeral

Speaking before boarding Air Force One on Sunday, Mr Trump again said the meeting went well, and that the Ukrainian leader was “calmer”.

“I think he understands the picture, I think he wants to make a deal,” he said, before turning to Mr Putin and Russia.

“I want him to stop shooting, sit down and sign a deal,” the US president said, adding he was “very disappointed that they did the bombing of those places (including Kyiv, where nine people were killed in a Russian airstrike on Friday) after discussions”.

However, Mr Trump said he thinks Mr Zelenskyy is ready to give up Crimea, which the Ukrainian leader has repeatedly said he would refuse to do.

He added that “we’ll see what happens in the next few days” and said “don’t talk to me about Crimea, talk to Obama and Biden about Crimea”.

Russia annexed Crimea in 2014, while Barack Obama was president.

Meanwhile, US secretary of state Marco Rubio told Sky’s US partner network NBC News that a peace deal to end the war was “closer in general than they’ve been any time in the last three years, but it’s still not there”.

“If this was an easy war to end, it would have been ended by someone else a long time ago,” he added on the Meet the Press show.

It comes after North Korea confirmed it had deployed troops to fight for Russia, months after Ukraine and Western officials said its forces were in Europe.

State media outlet KCNA reported North Korean soldiers made an “important contribution” to expelling Ukrainian forces from Russian territory, likely to be the Kursk region.

KCNA said leader Kim Jong Un made the decision to deploy troops to Russia and notified Moscow, and quoted him as saying: “They who fought for justice are all heroes and representatives of the honour of the motherland.”

It also quoted the country’s ruling Workers’ Party as saying the end of the battle to liberate Kursk showed the “highest strategic level of the firm militant friendship” between North Korea and Russia.

Last June, Mr Kim and Mr Putin signed a comprehensive strategic partnership treaty after a state visit – his first to the country in 24 years.

40 killed in blast at Iran's biggest port as Tehran denies explosion 'linked to fuel for missiles'

At least 40 people have been killed and several hundred more injured after an explosion and fire at Iran’s largest port, according to state media.

The blast, at the Shahid Rajaei container hub near the southern city of Bandar Abbas, happened on Saturday as Iran held a third round of talks with the US in Oman about Tehran’s nuclear programme.

Shipping containers burned, goods inside were badly damaged and the explosion was so powerful that windows several miles away were shattered, reports said.

The blast at the Shahid Rajaei port happened as Iran and the US met for the third round of negotiations over Tehran’s nuclear program.

Helicopters and aircraft dumped water from the air on the blaze and by Sunday afternoon it was 90% extinguished, the head of Iran’s Red Crescent Society told state media.

Officials said port activities had resumed in unaffected parts of Shahid Rajaei.

Out of the 752 people who had received treatment for their injuries, 190 were still being treated in medical centres on Sunday, according to Iran’s crisis management organisation.

Chemicals at the port were suspected to have worsened the blast, but the exact cause of the explosion was not clear.

More on Iran

Iran’s defence ministry denied international media reports that the explosion may be connected to the mishandling of solid fuel used for missiles.

The reports were “aligned with enemy psyops [psychological operations]”, according to a ministry spokesperson, who told state TV the blast-hit area did not contain any military cargo.

According to the Associated Press, British security company Ambrey said that the port in March received sodium perchlorate, which is used to propel ballistic missiles and the mishandling of which could have led to the explosion.

The Financial Times previously reported two Iranian vessels had shipped from China enough of the ingredient to propel up to 260 mid-range missiles.

It was reportedly to help Tehran replenish stocks after its missile attacks on Israel in 2024.

Iran’s military has sought to deny the delivery of sodium perchlorate from China.

Iran’s state-run Irna news agency reported on Sunday that Russian President Vladimir Putin deployed several emergency aircraft to Bandar Abbas to provide help.

Pilgrims travel to Pope Francis's tomb to remember the late pontiff

Anna and Irene have already been queuing for an hour or so, and they know they have a long wait still to come.

“Two hours, three hours, ten hours – what does it matter?” says Irena. “This is about eternity.”

They have come to Rome from Slovenia, Catholics who felt “Papa Francis would have wanted us to be here”.

And under the sun outside Santa Maria Maggiore, they are awaiting the opportunity to visit his tomb.

Francis, says Irena, “was like a rainbow” who lit up the world. Anna nods along: “We are so happy to be here.”

The Pope’s tomb has become a new source of pilgrimage.

More than 30,000 people came to view it during the first morning after the Pope’s funeral, the queue snaking from the front of the mighty basilica and then up and down across the square at the back.

More on Pope Francis

Some were curious visitors, others were devout followers – priests and nuns mixing in the queue with tourists and devoted locals.

All of these admired Francis; a very few actually knew him.

Father Alessandro Masseroni is a deacon who came to Rome to train to become a priest. On his phone, he shows me a photo of him and Francis, with the Pope offering words of encouragement.

He says: “I had the honour to serve Pope Francis and to talk to him many times and it was a special experience. I understand why he was so loved by all the people – he was simple and direct.

“He was sunny. St Francis was his role model and when I saw the first picture of the Pope’s tomb, the first thing I thought was of the tomb of St Francis of Assisi.

“Pope Francis will leave a legacy – it doesn’t end with his death but will continue.”

Video shows Pope’s tomb

What are your emotions now, as you wait to visit his tomb, I ask. Father Alessandro pauses and smiles.

“Many emotions of course, but mainly, I think… thankfulness.”

That has been a recurring aspect among so many of the people we have met in Rome over the past week – the sense that sadness for Francis’s death is outweighed by the sense that his was a life that should be celebrated.

Volodymyr Borysyak flew in from London on the morning of the Pope’s funeral to make his third pilgrimage to Rome.

Barely had he arrived than his phone was stolen, a crime he responded to by praying for the thief.

Volodymyr is a refugee from western Ukraine who worries that his home country’s plight is being forgotten by some of the world.

Now, the Pope who inspired him has died.

You might imagine that he would be resentful and angry. Instead, he is full of smiles.

The farewell to Pope Francis

“We are happy to be the pilgrims of the world and this is a special day,” he tells me. “I know the pope used to pray in this basilica so that is why we will stay so long here to visit Santa Maria Maggiore.

“I think Pope Francis was, is and will be the pope for the world, because of the mercy of his heart and his love for everybody.”
