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.

Microsoft Is Eliminating Passwords in August: Here’s What You Need to Do to Prepare
Microsoft Authenticator has already stopped autofilling passwords, but the biggest change comes next month.

In June, Microsoft Authenticator stopped letting users create new passwords. In July, it turned off the autofill password function. And in August, the login app will stop supporting passwords entirely, moving to more secure passkeys, such as a PIN, fingerprint or facial recognition.
Attila Tomaschek, CNET’s software senior writer and digital security expert, says that passkeys are a safer alternative to the risky password habits practiced by 49% of US adults, according to a recent survey by CNET.
«Passwords can be cracked, whereas passkeys need both the public and the locally stored private key to authenticate users, which can help mitigate risks like falling victim to phishing and brute-force or credential-stuffing attacks,» Tomaschek said.
Using the same password for several accounts or adding personal hints can be a convenient way to remember your login. But that puts you at a big risk for scammers, identity theft and fraud. Here’s more on Microsoft’s plan for eliminating passwords and how to make the switch to passkeys before August.
When will Microsoft Authenticator stop supporting passwords?
Microsoft Authenticator houses your passwords and lets you sign into all your Microsoft accounts using a PIN, facial recognition like Windows Hello, or other biometric data like a fingerprint. Authenticator can be used in other ways, such as verifying you’re logging in if you forgot your password, or using two-factor authentication as an extra layer of security for your accounts. In June, the company stopped letting users add passwords to Authenticator, but here’s a timeline of other changes you can expect from Microsoft.
- July 2025: You won’t be able to use the autofill password function.
- August 2025: You’ll no longer be able to use saved passwords.
If you still want to use passwords instead of passkeys, you can store them in Microsoft Edge. However, CNET experts recommend adopting passkeys during this transition. «Passkeys use public key cryptography to authenticate users, rather than relying on users themselves creating their own (often weak or reused) passwords to access their online accounts,» Tomaschek said.
Why are passkeys a better alternative to passwords?
So what exactly is a passkey? It’s a credential created by the Fast Identity Online Alliance that uses biometric data or a PIN to verify your identity and access your account. Think about using your fingerprint or Face ID to log into your account. That’s generally safer than using a password that is easy to guess or susceptible to a phishing attack.
Passkeys aren’t stored on servers like passwords. Instead, they’re stored only on your personal device. More conveniently, this takes the guesswork out of remembering your passwords and the need for a password manager.
How to set up a passkey in Microsoft Authenticator
Microsoft said in a May 1 blog post that it will automatically detect the best passkey to set up and make that your default sign-in option. «If you have a password and ‘one-time code’ set up on your account, we’ll prompt you to sign in with your one-time code instead of your password. After you’re signed in, you’ll be prompted to enroll a passkey. Then the next time you sign in, you’ll be prompted to sign in with your passkey,» according to the blog post.
To set up a new passkey, open your Authenticator app on your phone. Tap on your account and select «Set up a passkey.» You’ll be prompted to log in with your existing credentials. After you’re logged in, you can set up the passkey.

The AI Chatbots We Use Most, and How We Use Them
91% of AI users have a default artificial intelligence assistant they turn to for their AI tasks, a Menlo Ventures report has found.

If you have a particular artificial intelligence tool that you tend to try first every time you’re in need of an AI assist, you’re not alone. According to a new survey, 91% of people who use AI have a favorite chatbot they try first, whether it’s ChatGPT, Gemini, Alexa or something else.
A Menlo Ventures survey of 5,000 adults found that this «default tool dynamic» means most people using AI have chosen a general AI tool they’ll try first for every job, even if it’s not necessarily the best tool for the job.
In the report, ChatGPT is the AI assistant that tops default tools, with 28% of respondents choosing it first. It’s followed by Google’s Gemini at 23%, Meta AI and Amazon’s Alexa, both at 18% and Apple’s Siri at 16%. Other tools including Claude, Grok and Perplexity collectively make up another 33%.
Some of the most common ways people are using these AI tools include composing emails and other writing support, researching topics of interest and managing to-do lists, according to Menlo Ventures.
Some of that, Menlo Ventures says, is «first-mover advantage,» with tools like ChatGPT having built up a following by being the first to offer some chatbot and image-generation features. But, the company warns, «that position is not guaranteed,» with challengers moving fast.
«The consumer market for [large language models] is still nascent and far from saturated,» the report says, «leaving ample room for product innovation to shift market share over time.»
Overall, 61% of Americans have used AI in the last six months and nearly 1 in 5, 19%, rely on it daily, the report says.
