Microsoft unveiled two chips at its Ignite conference in Seattle on Wednesday.

The first, its Maia 100 artificial intelligence chip, could compete with Nvidia’s highly sought-after AI graphics processing units. The second, a Cobalt 100 Arm chip, is aimed at general computing tasks and could compete with Intel processors.

Cash-rich technology companies have begun giving their clients more options for cloud infrastructure they can use to run applications. Alibaba, Amazon and Google have done this for years. Microsoft, with about $144 billion in cash at the end of October, had 21.5% cloud market share in 2022, behind only Amazon, according to one estimate.

Virtual-machine instances running on the Cobalt chips will become commercially available through Microsoft’s Azure cloud in 2024, Rani Borkar, a corporate vice president, told CNBC in an interview. She did not provide a timeline for releasing the Maia 100.

Google announced its original tensor processing unit for AI in 2016. Amazon Web Services revealed its Graviton Arm-based chip and Inferentia AI processor in 2018, and it announced Trainium, for training models, in 2020.

Special AI chips from cloud providers might be able to help meet demand when there’s a GPU shortage. But Microsoft and its peers in cloud computing aren’t planning to let companies buy servers containing their chips, unlike Nvidia or AMD.

The company built its chip for AI computing based on customer feedback, Borkar explained.

Microsoft is testing how Maia 100 stands up to the needs of its Bing search engine’s AI chatbot (now called Copilot instead of Bing Chat), the GitHub Copilot coding assistant and GPT-3.5-Turbo, a large language model from Microsoft-backed OpenAI, Borkar said. OpenAI has fed its language models with large quantities of information from the internet, and they can generate email messages, summarize documents and answer questions with a few words of human instruction.

The GPT-3.5-Turbo model works in OpenAI’s ChatGPT assistant, which became popular soon after becoming available last year. Then companies moved quickly to add similar chat capabilities to their software, increasing demand for GPUs.

“We’ve been working across the board and [with] all of our different suppliers to help improve our supply position and support many of our customers and the demand that they’ve put in front of us,” Colette Kress, Nvidia’s finance chief, said at an Evercore conference in New York in September.

OpenAI has previously trained models on Nvidia GPUs in Azure.

In addition to designing the Maia chip, Microsoft has devised custom liquid-cooled hardware called Sidekicks that fit in racks right next to racks containing Maia servers. The company can install the server racks and the Sidekick racks without the need for retrofitting, a spokesperson said.

With GPUs, making the most of limited data center space can pose challenges. Companies sometimes put a few servers containing GPUs at the bottom of a rack like “orphans” to prevent overheating, rather than filling up the rack from top to bottom, said Steve Tuck, co-founder and CEO of server startup Oxide Computer. Companies sometimes add cooling systems to reduce temperatures, Tuck said.

Microsoft might see faster adoption of Cobalt processors than the Maia AI chips if Amazon’s experience is a guide. Microsoft is testing its Teams app and Azure SQL Database service on Cobalt. So far, they’ve performed 40% better than on Azure’s existing Arm-based chips, which come from startup Ampere, Microsoft said.

In the past year and a half, as prices and interest rates have moved higher, many companies have sought out methods of making their cloud spending more efficient, and for AWS customers, Graviton has been one of them. All of AWS’ top 100 customers are now using the Arm-based chips, which can yield a 40% price-performance improvement, Vice President Dave Brown said.

Moving from GPUs to AWS Trainium AI chips can be more complicated than migrating from Intel Xeons to Gravitons, though. Each AI model has its own quirks. Many people have worked to make a variety of tools work on Arm because of their prevalence in mobile devices, and that’s less true in silicon for AI, Brown said. But over time, he said, he would expect organizations to see similar price-performance gains with Trainium in comparison with GPUs.

“We have shared these specs with the ecosystem and with a lot of our partners in the ecosystem, which benefits all of our Azure customers,” she said.

Borkar said she didn’t have details on Maia’s performance compared with alternatives such as Nvidia’s H100. On Monday, Nvidia said its H200 will start shipping in the second quarter of 2024.

Waymo, Uber begin offering robotaxi rides in Austin ahead of SXSW

A Waymo car drives along a street on March 01, 2023 in San Francisco, California. Waymo, Alphabet’s self-driving car division, announced that it has laid off over 135 employees in a second round of layoffs this year.

Waymo on Tuesday began offering robotaxi rides in Austin, Texas, through the Uber app.

The launch sets up Waymo to showcase its driverless technology during Austin’s annual South by Southwest festival that kicks off Friday. Approximately 300,000 people descend on the Texas capital to attend SXSW on average each year, according to the Austin Convention & Visitors Bureau.

“We can’t wait for Austin locals and visitors alike to experience Waymo One via the Uber app starting this week,” said Nicole Gavel, Waymo’s head of business development and strategic partnerships, in a statement.

Waymo previously said it would be launching in Austin, among several other U.S. cities, in 2025. 

Austin is the first market where Uber will manage and dispatch a fleet of Waymo vehicles. Riders in Phoenix can book Waymo rides through the Uber app, but the ride-sharing company does not manage the Waymo fleet in that market. The two companies’ partnership will expand to Atlanta later this year, where Waymo employees have already begun taking fully autonomous trips across the city, the company said Tuesday.

Uber sold off its autonomous vehicle, or AV, unit in 2020 after a string of earlier safety incidents including one fatality. The two companies have not disclosed how they split revenue for Waymo rides booked through the Uber app.

“With Waymo’s technology and Uber’s proven platform, we’re excited to introduce our customers to a future of transportation that is increasingly electric and autonomous,” Uber CEO Dara Khosrowshahi said in a statement. 

Alphabet-owned Waymo, which has pulled far ahead of self-driving car competitors in the U.S., is currently serving over 200,000 paid trips per week across San Francisco, Los Angeles and Phoenix, according to the company.

Waymo’s Austin expansion also sets up the company for a potential clash with Elon Musk-led Tesla later this year. 

Tesla has promised to launch a driverless rideshare service in Austin in June. The company already produces electric cars with partially automated driving systems. These require a human driver at the wheel ready to steer or brake at any time. Tesla has designed a robotaxi, called the CyberCab, but the company does not yet produce it.

Waymo riders will be able to travel across 37 square miles of Austin, covering neighborhoods including the city’s downtown, Hyde Park and Montopolis, the company said. Uber users who request an Uber X, Uber Comfort, Uber Green or Uber Comfort Electric will be shown the option to match with Waymo vehicles when available, the company added.

The price of bitcoin failed to recover the $85,000 level – where it traded before President Donald Trump’s announcement of a U.S. crypto reserve sent it soaring – after a sell-off driven by tariff concerns knocked it down.

Bitcoin was last lower by 2% on Tuesday at $83,508.78, according to Coin Metrics, and off its all-time high by 23%.

Ripple-related XRP and Cardano’s ADA, two of the smaller cap coins mentioned in Trump’s surprise announcement, were still holding onto some of their gains from the rally. Solana’s SOL token also fully reversed its gain.

Bitcoin before and after Trump’s crypto reserve announcement

Shares of Coinbase, Robinhood and Strategy, formerly known as MicroStrategy, were all lower in premarket trading.

Risk assets including cryptocurrencies suffered steep declines on Monday as traders grappled with concerns that proposed tariffs were on track to take effect. That overshadowed the exuberance around Trump’s so named U.S. “strategic crypto reserve,” which some traders had hoped would pull bitcoin out of a slump. After reaching its record in January, it posted its worst month since 2022 in February.

Investors and analysts warn that economic uncertainty could keep its hold on bitcoin throughout March, with the crypto industry absent a specific catalyst. With the idea of a U.S. reserve holding crypto largely priced in, regulatory clarity through clear legislation may be the more likely catalyst to jump start prices in a meaningful way.

“The lack of information on the amount of crypto the U.S. government will buy, and how the purchase will be funded, coupled with fears of a market retreat if expectation does not meet reality, means that the likelihood of high volatility in the crypto markets will continue,” said Deutsche Bank analyst Marion Laboure said in a note Tuesday.

Investors this week will keep an eye on the inaugural White House Crypto Summit, which is scheduled to take place this Friday, for updates on the details of the reserve, as well as the administration’s plans to support the industry.

Why automakers including Honda and Toyota are pouring millions into rockets and satellites

Why automakers including Honda and Toyota are pouring millions into rockets and satellites

In January, Toyota said its mobility software subsidiary “Woven by Toyota” was investing $44 million into Japanese rocket maker Interstellar Technologies. Rival Honda has been developing a proprietary reusable rocket since 2019 to launch low-earth orbit satellites to space. Chinese automaker Geely Holding Group, a Tesla competitor, has invested $326 million to manufacture its own satellites.

“What are those satellites going to be used for and what are they already being used for?” said Micah Walter-Range, president of consulting firm Caelus Partners. “Some of it is for improving navigation services for cars. Some of it’s for mapping. If you think about what’s going to be needed a little further down the road for autonomous vehicles, having full awareness of what’s going on on the road is incredibly valuable.”

Cars today use satellite connectivity for tracking and location, software updates and entertainment like satellite radio. But as cars become more and more connected, automakers need the infrastructure to make that possible. That’s where satellites, and the rockets needed to launch them, come into play. One recent report estimates that by 2030, connected vehicles could be a $742 billion annual revenue opportunity for automakers and suppliers.

“In the smartphone world, Apple is shifting from a single device sale to additional services that can be provided throughout the life of that device,” Walter-Range said. “So for a car, it’s the same deal. You know, once you sell that car, are there additional revenue streams that you can get by providing services? Some of those services can be delivered from space.”

One model is charging subscriptions for advanced driver assistance systems. General Motors‘ Super Cruise uses cameras, sensors and real-time location and map data from GPS satellites to allow the vehicle to do things like automatically steer and keep the car centered in a lane. In the company’s fourth-quarter earnings report, GM CEO Mary Barra said the company expected that within the next five years, Super Cruise would bring in about $2 billion in annual revenue for the company.
