Nvidia will begin selling a new AI acceleration chip later this year, part of the company's efforts to secure its leadership in the artificial intelligence computing revolution.

The H100 "Hopper" processor, which Nvidia Chief Executive Jensen Huang unveiled in March, should let AI developers speed up their research and build more advanced AI models, especially for complex challenges like understanding human language and piloting self-driving cars. The chip is expected to begin shipping next quarter.

The H100 processor has a whopping 80 billion transistors and measures 814 square millimeters, which is almost as big as is physically possible with today's chipmaking equipment. (CNET got an advance look at the H100 Hopper chips and Nvidia's new Voyager building that will house hardware and software development work.)

The H100 competes with huge, power-hungry AI processors like AMD's MI250X, Google's TPU v4 and Intel's upcoming Ponte Vecchio. Such chips are goliaths most often found in the preferred environment for AI training systems, data centers packed with racks of computing gear and laced with fat copper power cables.

The new chip embodies Nvidia's evolution from a designer of graphical processing units used for video games to an AI powerhouse. The company did this by adapting GPUs for the particular mathematics of AI like multiplying arrays of numbers. 

Circuitry for speeding up AI is becoming increasingly important as the technology arrives in everything from iPhones to Aurora, expected to be the world's fastest supercomputer. Chips like the H100 are critical for speeding up tasks such as training an AI model to translate live speech live from one language to another or to automatically generate video captions. Faster performance means AI developers can tackle more challenging tasks like autonomous vehicles and speed up their experimentation, but one of the biggest areas of improvement is in processing language.

Linley Gwennap, an analyst at TechInsights, says the H100, along with Nvidia's software tools, cements its position in the AI processor market. 

"Nvidia towers over its competitors," Gwennap wrote in a report in April.

Pindrop, a longtime Nvidia customer that uses AI-based voice analysis to help customer service representatives authenticate legitimate clients and spot scammers, says the chipmaker's steady progress has let it expand to identifying audio deepfakes. Deepfakes are sophisticated computer simulations that can be used to perpetrate fraud or spread misinformation.

"We couldn't get there if we didn't have the latest generation of Nvidia GPUs," said Ellie Khoury, the company's director of research.

Training their AI system involves processing an enormous quantity of information, including audio data from 100,000 voices, each one manipulated in several ways to simulate things like background chatter and bad telephone connections. That's why H100 advancements, like expanded memory and faster processing, are important to AI customers.

Nvidia estimates its H100 is six times faster overall than the A100 predecessor the company launched two years ago. One important area that definitely benefits is natural language processing. Also known as NLP, the AI domain helps computers understand your speech, summarize documents and translate languages, among other tasks.

Nvidia is a strong player in NLP, a field at the vanguard of AI. Google's Palm AI system, can tease apart cause and effect in a sentence, write programming code, explain jokes, and play the emoji movie game. But Nvidia's flexible GPUs are popular with researchers. For example, Meta, Facebook's parent company, this week released sophisticated NLP technology for free to accelerate AI research, and it runs on 16 Nvidia GPUs.

With the H100, NLP researchers and product developers can work faster, said Ian Buck, vice president of Nvidia's hyperscale and high-performance computing group. "What took months should take less than a week."

The H100 offers a big step up in transformers, an AI technology created by Google that can assess the importance of context around words and detect subtle relationships between information in one area and another. Data like photos, speech and text that's used to train AI often must be carefully labeled before use, but transformer-based AI models can use raw data like vast tracts of text on the web, said Aidan Gomez, co-founder of AI language startup Cohere.

"It reads the internet. It consumes the internet," Gomez said, then the AI model turns that raw data into useful information that captures what humans know about the world. The effect transformers "shot my timeline forward decades" when it comes to the pace of AI progress.

We all stand to benefit from the H100's ability to accelerate AI research and development, said Hang Liu, an assistant professor at the Stevens Institute of Technology. Amazon can spot more fake reviews, chipmakers can lay out chip circuitry better and a computer can turn your words into Chinese as you speak them, he said. "Right now AI is completely reshaping almost any sector of commercial life."

It's been 20 years since wrestler The Rock burst onto screens as the villainous Scorpion King, and now Dwayne Johnson is playing the bad guy again. In the first Black Adam footage, unveiled at DC Fandome on Saturday, Johnson takes on the power of Shazam as one of DC comics' baddest bad guys. "The truth is I was born to play Black Adam," Johnson said at the virtual fan event before the footage played, promising viewers huge action sequences and "breathtaking 'holy shit' scenes."

Johnson revealed an early scene from the film, in which archeologists make the mistake of zapping Black Adam with a bolt of lightning. The hooded figure promptly turns a dude to dust, catches a bullet in midair and then takes to the sky as the title appears.

Black Adam is set to premiere on July 29, 2022. Arrayed against Johnson are good guys Noah Cintineo, Quintessa Swindell, Sarah Shahi, Aldis Hodge and Pierce Brosnan as Doctor Fate. It's directed by Jaume Collet-Serra, best known for a run of recent Liam Neeson actioners like Non-Stop and The Commuter.

Created by Otto Binder and CC Beck in 1945, Black Adam was a bad guy in the original Captain Marvel series published by Fawcett comics. DC later rebranded the old Captain Marvel (for obvious reasons), paving the way for the 2019 film Shazam! starring Zachary Levi. Johnson was originally supposed to appear in that film, but Black Adam was spun off into its own film, which he describes as a "passion project."

Black Adam was meant to come out in 2021 but got delayed due to the COVID pandemic.

DC's lineup of forthcoming movies also includes Robert Pattinson as The Batman, appearing alongside Zoe Kravitz and Colin Farrell. Underwater sequel Aquaman and the Lost Kingdom is also on the way, with Jason Momoa and Amber Heard. Meanwhile, The Flash, starring Ezra Miller as the scarlet speedster, is reported to unite a multiverse of old and new superhero stars, including Ben Affleck's Batman as seen in the Justice League films and Michael Keaton back in the batsuit from Tim Burton's Batman films. 

Along with The Suicide Squad spin-off Peacemaker from James Gunn and John Cena on HBO Max, DC's small screen adventures continue with the CW's Arrowverse shows such as Batwoman, The Flash, Superman & Lois, and Naomi, produced by Ava DuVernay. Animated titles include Batman: Caped Crusader, limited series Aquaman: King of Atlantis, adult animated comedy series Harley Quinn and video game adaptation Injustice featuring Superman as a villain. DC games in the works include Gotham Knights and Suicide Squad: Kill the Justice League.

This story is part of CES, where CNET covers the latest news on the most incredible tech coming soon.

Some companies discount older phones after releasing new models. Samsung is leaning into that concept with the $700 Galaxy S21 FE, which launches on Jan. 11 and will be available in the US and other countries. Samsung's new Fan Edition phone will fill the same role as its predecessor, the Galaxy S20 FE, by becoming the new affordable option in Samsung's premium Galaxy S lineup.

The Galaxy S21 FE, announced just ahead of CES 2022, will serve as a replacement for the Galaxy S21 once Samsung eventually phases out that family of devices. If you typically wait for the newest Galaxy S phone to launch so that you can get the previous model at a discount, you're Samsung's target audience for the Galaxy S21 FE. Samsung doesn't have any immediate plans to stop selling the Galaxy S21, which launched about a year ago. But it will position the Galaxy S21 FE as its previous-generation option once it does cycle out that series, the company said.

This isn't a new strategy. The past few years have seen a resurgence in midtier and budget phones across the industry. Even Apple revived its wallet-friendly $400 iPhone SE in 2020. But Samsung's strategy is different from Apple's in one key way. Samsung is essentially borrowing certain aspects of its mainstream Galaxy S21 phone and selling it as a midrange device. Apple, meanwhile, tends to keep older phones like the iPhone 11 in its lineup to fill that gap between its budget SE and high-end iPhones. 

Similar to Samsung's first FE phone, the Galaxy S21 FE comes with features that were once reserved for more expensive phones, such as a triple-lens camera, 5G support, reverse wireless charging and a screen that can boost its refresh rate to 120Hz. 

The Galaxy S21 FE is arriving as Samsung's smartphone lineup has become increasingly crowded and will likely continue to expand. The company is expected to launch the Galaxy S22 lineup in the early part of the year, just as it has done in the past. It also recently launched the $250 Galaxy A13 5G in the US and also sells other midtier phones such as the Galaxy A52 5G.

Here's a closer look at what to expect from Samsung's new midtier Galaxy phone.

Galaxy S21 FE specs: All the important details and features

CNET's Andrew Hoyle praised the Galaxy S20 FE and gave it an Editors' Choice Award for its excellent balance of performance and price. It seems like Samsung is carrying that approach forward with the Galaxy S21 FE, which appears to be a hybrid of the Galaxy S20 FE and Galaxy S21. 

It has the same processor as the Galaxy S21, which means it will run on Qualcomm's Snapdragon 888 chip in the US, but otherwise has a lot in common with the Galaxy S20 FE. For example, both this year's FE phone and the 2020 version have a 4,500-mAh battery and a triple-lens camera with a 12-megapixel ultrawide camera, a 12-megapixel wide camera and an 8-megapixel telephoto lens. Both the Galaxy S21 FE and Galaxy S20 FE also have a 32-megapixel front camera, which is a step up from the Galaxy S21's 10-megapixel selfie camera.

You can also expect to see a similar selection of the software-based photography features typically available on Samsung phones. In addition to night and portrait modes, there's also a tool for shooting with the front and rear lenses simultaneously. It's similar to the Galaxy S21's Director's View, but slightly different. You can't switch between the different rear lenses in addition to shooting with both the front and rear cameras on the Galaxy S21 FE as you can on the Galaxy S21. 

One of the few areas in which the Galaxy S21 FE differs from the Galaxy S20 FE and Galaxy S21 is screen size. At 6.4 inches, the Galaxy S21 FE's screen is larger than the Galaxy S21's (6.2 inches), but slightly smaller than the Galaxy S20 FE's (6.5 inches). But like those two phones, the Galaxy S21 FE will support the ability to boost the refresh rate up to 120Hz for smoother scrolling. 

You'll get both flavors of 5G in the Galaxy S21 (sub-6GHz and millimeter-wave), and the base model will include 6GB of memory and 128GB of storage. There's no microSD card slot, but Samsung is offering the phone in another option that comes with 8GB of RAM and 256GB of storage for $770.

Samsung is continuing its tradition of offering multiple color options for its new phone, although the Galaxy S21 FE won't come in as many different shades as the Galaxy S20 FE. The new phone will be available in white, graphite, lavender purple and olive green, while its predecessor came in navy blue, lavender, red, mint green, white and orange. 

Is the Samsung Galaxy S21 FE worth it?

We can't recommend the Galaxy S21 FE until we've spent more time testing it. But it looks like a promising option for those who want a general-purpose phone with a reliable camera, solid performance and a spacious screen. At $700 in the US, it's $100 less than the current Galaxy S21 and $500 less than the top-of-the-line $1,200 Galaxy S21 Ultra.

The problem, however, is that Samsung is facing a lot of competition, even within its own product line. The Galaxy S22 is expected to launch in early 2022, and there's a chance it may only cost $100 more than the Galaxy S21 FE if Samsung sticks with its current pricing structure. 

Based on Samsung's history, it seems fair to assume that the base Galaxy S22 will come with a new Qualcomm Snapdragon processor and a sharper telephoto lens than the Galaxy S21 FE. It might also come with a 50-megapixel camera sensor, according to well-known leaker Ice Universe. Significantly faster charging speeds are also a possibility, according to FronTron and Ice Universe. A more powerful processor, better camera and quicker charging could be enough to justify the extra $100 for some shoppers, possibly making the Galaxy S21 FE feel lost in the lineup.

There's also Google's $600 Pixel 6 smartphone, which is $100 cheaper than the Galaxy S21 FE. Google's latest Pixel is among the first to come with the company's new Tensor chip, which particularly shines in the device's camera. Patrick Holland gave it a CNET Editors' Choice Award for its excellent combination of elegant design, powerful performance and superb photography. 

We'll know more once we've had a chance to check out the Galaxy S21 FE ourselves. To learn more about how it compares with the Galaxy S20 FE, Galaxy S21 and Google Pixel 6, check out the table below.

It's World Music Day, and if you own an Amazon Echo -- or really any smart speaker -- chances are good you use it to listen to music. It makes sense: These speakers have all kinds of built-in hardware to make songs sound great in whatever room they're in, and the addition of Alexa makes ordering up your next track easier than it's ever been. Just say what you want to listen to and it plays.

But for many Alexa-users, that music experience can be faster, smoother and even better-sounding. Here's how to get the most out of your Alexa speaker when listening to music.
