NVIDIA’s GPUs powered the AI revolution. Its new Blackwell chips are up to 30 times faster

In less than two years, NVIDIA’s H100 chips, which are used by nearly every AI company in the world to train large language models that power services like ChatGPT, made it one of the world’s most valuable companies. On Monday, NVIDIA announced a next-generation platform called Blackwell, whose chips are between seven and 30 times faster than the H100 and use 25 times less power.

“Blackwell GPUs are the engine to power this new Industrial Revolution,” said NVIDIA CEO Jensen Huang at the company’s annual GTC event in San Jose attended by thousands of developers, and which some compared to a Taylor Swift concert. “Generative AI is the defining technology of our time. Working with the most dynamic companies in the world, we will realize the promise of AI for every industry,” Huang added in a press release.

NVIDIA’s Blackwell chips are named in honor of David Harold Blackwell, a mathematician who specialized in game theory and statistics. NVIDIA claims that Blackwell is the world’s most powerful chip. It offers a significant performance upgrade to AI companies with speeds of 20 petaflops compared to just 4 petaflops that the H100 …read more

We’re one step closer to a global cybersecurity standard for smart home devices

As useful as connected devices like video doorbells and smart lights are, it’s wise to exercise caution when using connected tech in your home, especially after years of reading about security camera hacks, fridge botnet attacks, and smart stoves turning themselves on. But until now, there hasn’t been an easy way to assess a product’s security chops. A new program from the Connectivity Standards Alliance (CSA), the group behind the smart home standard Matter, wants to fix that.

Announced this week, the CSA’s IoT Device Security Specification is a baseline cybersecurity standard and certification program that aims to provide a single, globally recognized security certification for consumer IoT devices.

Device makers who adhere to the s…

Steam streamlines its family sharing features

Today, Steam launched Steam Families, an overhaul of its family sharing system. The new system gets rid of limits on how many people can play games from one library, makes buying games for your kids easier, and adds new parental controls and sharing options.

Before, you needed to use two different systems — Family Sharing and Family View — if you wanted to share your library but limit which games your kids could play. Also under the old approach, only one person at a time could play a game from another’s library. Now — to use Steam’s example — if you’re playing your copy of Portal 2 and someone else wants to play Half-Life from your library, that’s fine. They’ll only be booted if you start up Portal 2 while they’re playing it from your…

Tanks of the Triassic: New crocodile ancestor identified

Tanks of the Triassic: New crocodile ancestor identified

Dinosaurs get all the glory. But aetosaurs, a heavily armored cousin of modern crocodiles, ruled the world before dinosaurs did. These tanks of the Triassic came in a variety of shapes and sizes before going extinct around 200 million years ago. Today, their fossils are found on every continent except Antarctica and Australia. …read more

Backyard insect inspires invisibility devices, next gen tech

Backyard insect inspires invisibility devices, next gen tech

Leafhoppers, a common backyard insect, secrete and coat themselves in tiny mysterious particles that could provide both the inspiration and the instructions for next-generation technology, according to a new study. In a first, the team precisely replicated the complex geometry of these particles, called brochosomes, and elucidated a better understanding of how they absorb both visible and ultraviolet light. …read more

Nvidia reveals Blackwell B200 GPU, the ‘world’s most powerful chip’ for AI

Nvidia’s must-have H100 AI chip made it a multitrillion-dollar company, one that may be worth more than Alphabet and Amazon, and competitors have been fighting to catch up. But perhaps Nvidia is about to extend its lead — with the new Blackwell B200 GPU and GB200 “superchip.”

Nvidia says the new B200 GPU offers up to 20 petaflops of FP4 horsepower from its 208 billion transistors. Also, it says, a GB200 that combines two of those GPUs with a single Grace CPU can offer 30 times the performance for LLM inference workloads while also potentially being substantially more efficient. It…

Microsoft is planning some more pre-Build AI announcements

Microsoft is planning some more pre-Build AI announcements

It’s shaping up to be a busy spring for Microsoft, which has multiple events lined up over the next few months. Not only is there a work and Copilot-centric event this Thursday and almost certainly an Xbox showcase coming up in early June, but Build is on the horizon. The company’s major developer conference is set to run from May 21 until May 23. However, three days apparently isn’t long enough to cram in everything Microsoft wants to talk about.

The company sent Engadget an invite to a private event taking place on May 20, the day before Build starts. Details are scant, but Microsoft says CEO Satya Nadella will dig into its “AI vision across hardware and software.” There won’t be a livestream of the briefing, but reporters who attend in person will learn the news first and get hands-on demos.

Microsoft having an “AI vision” that spans across hardware and software lines up with recent reports that the company is gearing up to release its first “AI PCs.” This week’s event is expected to include at least the business and commercial-focused versions of the OLED Surface Pro 10 and Surface Laptop 6.

Two artificial intelligences talk to each other

Two artificial intelligences talk to each other

Performing a new task based solely on verbal or written instructions, and then describing it to others so that they can reproduce it, is a cornerstone of human communication that still resists artificial intelligence (AI). A team has succeeded in modelling an artificial neural network capable of this cognitive prowess. After learning and performing a series of basic tasks, this AI was able to provide a linguistic description of them to a ‘sister’ AI, which in turn performed them. …read more

Holographic message encoded in simple plastic

Holographic message encoded in simple plastic

Important data can be stored and concealed quite easily in ordinary plastic using 3D printers and terahertz radiation, scientists show. Holography can be done quite easily: A 3D printer can be used to produce a panel from normal plastic in which a QR code can be stored, for example. The message is read using terahertz rays — electromagnetic radiation that is invisible to the human eye. …read more

Breathe, don’t vent: Turning down the heat is key to managing anger

Breathe, don’t vent: Turning down the heat is key to managing anger

Venting about a source of anger might feel good in the moment, but it’s not effective at reducing the rage, new research suggests. Instead, techniques often used to address stress — deep breathing, mindfulness, meditation, yoga or even counting to 10 — have been shown to be more effective at decreasing anger and aggression. …read more
