Intel’s 2024 PC Chips Getting a Speed Boost From New Power Tech

PowerVia should speed up Intel PC chips — and maybe even rival designs if Intel can persuade competitors to use its manufacturing services.

Intel’s Arrow Lake processor for 2024 PCs will get a speed boost thanks to a new technique sending electrical power through its chips.

In tests detailed Monday, Intel said a technology it calls PowerVia offered a 6% speed boost on test chips. Another big change called RibbonFET that’s coming with Arrow Lake should offer further advantages.

That’s a big deal for Intel, which has struggled to reclaim a once formidable chipmaking advantage that it lost to Taiwan Semiconductor Manufacturing Co. (TSMC) and Samsung. Those two companies are «foundry» companies that make other chips, notably Intel’s top competitors: Apple, AMD, Nvidia and Qualcomm, but they aren’t expected to match PowerVia until later.

If PowerVia and RibbonFET arrive on time in 2024 with the Intel 20A manufacturing process, then are improved with 18A in 2025, it could help Intel better match rival chips when it comes to packing in lots of circuitry and running efficiently to extend battery life. Apple’s MacBook laptops run unplugged for hours, and many models completely do away with a cooling fan to keep their chips from overheating.

«It looks like a good incremental step,» but not a permanent advantage for Intel, Tirias Research analyst Kevin Krewell said of PowerVia. «Everybody’s going to follow suit and will have the same technology in place over time.»

And because Intel is trying to become a foundry too, it could mean some of those competitors actually could become customers that, like Intel’s own chips, benefit. Intel missed out on making smartphone chips, but in Intel’s ideal future, it could be building the Apple processor that powers a future iPhone. 

Meet backside power delivery

Chips process data and perform calculations using tiny electrical switches called transistors that can switch on and off billions of times per second. Today, the necessary power to do that comes on equally tiny electrical links that wind their way through a complex 3D labyrinth of wires that also carry instruction signals to the transistors.

But with Arrow Lake, the 2024 successor to this year’s Meteor Lake processor for PCs, Intel will separate the power delivery from the communication links, moving it to the opposite face of the chip. In the semiconductor industry, it’s called a backside power delivery network, but Intel calls its version PowerVia.

«PowerVia is a revolutionary change for on-chip interconnects that improves power, performance, area, and cost,» all important dimensions of transistor design, said Ben Sell, an Intel vice president who worked on the technology.

Problems with manufacturing progress

By incorporating PowerVia in its highest volume, highest profile processor, Intel is counting on backside power delivery working well and not degrading manufacturing with flawed chips. To guard against that possible disaster, Intel developed PowerVia using test chips built with its current Intel 4 manufacturing process, used to make elements of Meteor Lake. It works well enough that it’ll be standard for Intel 20A and its successor, 18A.

PowerVia is a crucial element to Intel’s recovery effort. In the relentless effort to miniaturize transistors, to keep pace with Moore’s Law, Intel faltered a decade ago and hasn’t fully recovered. Although Samsung and TSMC are working on backside power delivery, PowerVia could beat it to market. For example, TSMC’s backside power technology isn’t expected until 2026.

«From everything we know, this is coming a node ahead of what the industry is doing and gives our customers the advantages of PowerVia as soon as possible,» Sell said. A node is a major step in chip manufacturing technology.

PowerVia adds new processing steps to the hundreds already required to make a chip. Once the transistors are carefully built on the front of a silicon wafer of chips, the wafer must be flipped over, ground thinner, polished, and have power connections installed.

That adds cost and time. But removing the power lines from the front of the wafer means there’s more room for communication links, simplifying designs and overall lowers manufacturing costs.

Google races to put Gemini at the center of Android before Apple’s AI reboot

Google is using its latest Android rollout to position Gemini as the AI layer across phones, Chrome, laptops and cars.

Google is using its latest Android rollout to make Gemini less of a chatbot and more of an operating layer across the phone, browser, car and laptop, just weeks before Apple is expected to show its own Gemini-powered Apple Intelligence reboot at WWDC.
Ahead of its Google I/O developer conference next week, the company previewed a number of Android updates, including AI-powered app automation, a smarter version of Chrome on Android, new tools for creators, a redesigned Android Auto experience, and a sweeping set of new security features.
Alphabet is counting on Gemini to help Google compete directly with OpenAI and Anthropic in the market for artificial intelligence models and services, while also serving as the AI backbone across its expansive portfolio of products, including Android. Meanwhile, Gemini is powering part of Apple’s new AI strategy, giving Google a role in the iPhone maker’s reset even as it races to prove its own version of personal AI on the phone is further along.
Sameer Samat, who oversees Google’s Android ecosystem, told CNBC that Google is rebuilding parts of Android around Gemini Intelligence to help users complete everyday tasks more easily.
“We’re transitioning from an operating system to an intelligence system,” he said.
As part of Tuesday’s announcements. Google said Gemini Intelligence will be able to move across apps, understand what’s on the screen and complete tasks that would normally require a user to jump between multiple services. That means Android is moving beyond the traditional assistant model, where users ask a question and get an answer, and acting more like an agent.
For instance, Google says Gemini can pull relevant information from Gmail, build shopping carts and book reservations. Samat gave the example of asking Gemini to look at the guest list for a barbecue, build a menu, add ingredients to an Instacart list and return for approval before checkout.
A big concern surrounding agentic AI involves software taking action on a user’s behalf without permissions. Samat said Gemini will come back to the user before completing a transaction, adding, “the human is always in the loop.”
Four months after announcing its Gemini deal with Google, Apple is under pressure to show a more capable version of Apple Intelligence, which has been a relative laggard on the market. Apple has long framed privacy, hardware integration and control of the user experience as its advantages.
Google’s Android push is designed to show it can bring AI deeper into the device experience while still giving users control over what Gemini can see, where it can act and when it needs confirmation.
The app automation features will roll out in waves, starting with the latest Samsung Galaxy and Google Pixel phones this summer, before expanding across more Android devices, including watches, cars, glasses and laptops later this year.
The company is also redesigning Android Auto around Gemini, turning the car into another major surface for its assistant. Android Auto is in more than 250 million cars, and Google says the new release includes its biggest maps update in a decade and Gemini-powered help with tasks like ordering dinner while driving.
Alphabet’s AI strategy has been embraced by Wall Street, which has pushed the company’s stock price up more than 140% in the past year, compared to Apple’s roughly 40% gain. Investors now want to see how Gemini can become more central to the products people use every day.

Waymo recalls 3,800 robotaxis after glitch allowed some vehicles to ‘drive into standing water’

Waymo issued a voluntary recall of about 3,800 of its robotaxis to fix software issues that could allow them to drive into flooded roadways.

Waymo is recalling about 3,800 robotaxis in the U.S. to fix software issues that could allow them to “drive onto a flooded roadway,” according to a letter on the National Highway Traffic Safety Administration’s website.
The voluntary recall is for Waymo vehicles that use the company’s fifth and sixth generation automated driving systems (or ADS), the U.S. auto safety regulator said in the letter posted Tuesday.
Waymo autonomous vehicles in Austin, Texas, were seen on camera driving onto a flooded street and stalling, requiring other drivers to navigate around them. It’s the latest example of a safety-related issue for the Alphabet-owned AV unit that’s rapidly bolstering its fleet of vehicles and entering new U.S. markets.
Waymo has drawn criticism for its vehicles failing to yield to school buses in Austin, and for the performance of its vehicles during widespread power outages in San Francisco in December, when robotaxis halted in traffic, causing gridlock.
The company said in a statement on Tuesday that it’s “identified an area of improvement regarding untraversable flooded lanes specific to higher-speed roadways,” and opted to file a “voluntary software recall” with the NHTSA.
“Waymo provides over half a million trips every week in some of the most challenging driving environments across the U.S., and safety is our primary priority,” the company said.
Waymo added that it’s working on “additional software safeguards” and has put “mitigations” in place, limiting where its robotaxis operate during extreme weather, so that they avoid “areas where flash flooding might occur” in periods of intense rain.

Qualcomm tumbles 13% as semiconductor stocks retreat from historic AI-fueled surge

Semiconductor equities reversed sharply after a broad AI-driven advance, with Qualcomm suffering its worst day since 2020 amid inflation concerns and rising oil prices.

Semiconductor stocks fell sharply on Tuesday, reversing course after an extensive rally that had expanded the artificial intelligence investment theme well past Nvidia and driven the industry to unprecedented levels.

Qualcomm plunged 13% and was on track for its steepest single-day decline since 2020. Intel shed 8%, while On Semiconductor and Skyworks Solutions each lost more than 6%. The iShares Semiconductor ETF, which benchmarks the overall sector, fell 5%.

The sell-off came after a key gauge of consumer prices came in above forecasts, and as conflict in Iran pushed crude oil higher—prompting investors to shift away from riskier assets.

The preceding advance had widened the AI opportunity set beyond longtime industry leader Nvidia, which for much of the past several years had largely carried the market to new peaks on its own.

Explosive appetite for central processing units, along with the graphics processing units that power large language models, has sent chipmakers to all-time highs.

Market participants are wagering that the shift from AI model training to autonomous agents will lift demand for additional AI hardware. Among the beneficiaries are memory chip producers, which are raising prices as supply remains tight.

Micron Technology slid 6%, and Sandisk cratered 8%. Sandisk’s stock has surged more than six times over since January.
