Google says its AI designs chips better than humans – experts disagree

Can AI design a chip that’s more efficient than human-made ones?

Google DeepMind says its artificial intelligence has helped design chips that are already being used in data centres and even smartphones. But some chip design experts are sceptical of the company’s claims that such AI can plan new chip layouts better than humans can.

The newly named AlphaChip method can design “superhuman chip layouts” in hours, rather than relying on weeks or months of human effort, said Anna Goldie and Azalia Mirhoseini, researchers at Google DeepMind, in a blog post. This AI approach uses reinforcement learning to figure out the relationships among chip components and gets rewarded based on the final layout quality. But independent researchers say the company has not yet proven such AI can outperform expert human chip designers or commercial software tools – and they want to see AlphaChip’s performance on public benchmarks involving current, state-of-the-art circuit designs.

“If Google would provide experimental results for these designs, we could have fair comparisons, and I expect that everyone would accept the results,” says Patrick Madden at Binghamton University in New York. “The experiments would take at most a day or two to run, and Google has near-infinite resources – that these results have not been offered speaks volumes to me.” Google DeepMind declined to offer additional comment.

Google DeepMind’s blog post accompanies an update to Google’s 2021 Nature journal paper about the company’s AI process. Since that time, Google DeepMind says that AlphaChip has helped design three generations of Google’s Tensor Processing Units (TPU) – specialised chips used to train and run generative AI models for services such as Google’s Gemini chatbot.

The company also claims that the AI-assisted chip designs perform better than those designed by human experts and have been improving steadily. The AI achieves this by reducing the total length of wires required to connect chip components – a factor that can lower chip power consumption and potentially improve processing speed. And Google DeepMind says that AlphaChip has created layouts for general-purpose chips used in Google’s data centres, along with helping the company MediaTek develop a chip used in Samsung mobile phones.

But the code publicly released by Google lacks support for common industry chip data formats, which suggests the AI method is currently more suited for Google’s proprietary chips, says Igor Markov, a chip design researcher. “We really don’t know what AlphaChip is today, what it does and what it doesn’t do,” he says. “We do know that reinforcement learning takes two to three orders of magnitude greater compute resources than methods used in commercial tools and is usually behind [in terms of] results.”

Markov and Madden critiqued the original paper’s controversial claims about AlphaChip outperforming unnamed human experts. “Comparisons to unnamed human designers are subjective, not reproducible, and very easy to game. The human designers may be applying low effort or be poorly qualified – there is no scientific result here,” says Markov. “Imagine if AlphaGo reported wins over unnamed Go players.”

In 2023, an independent expert who had reviewed Google’s paper retracted his Nature commentary article that had originally praised Google’s work. That expert, Andrew Kahng at the University of California, San Diego, also ran a public benchmarking effort that tried to replicate Google’s AI method and found it did not consistently outperform a human expert or conventional computer algorithms. The best-performing methods were commercial software for chip design from companies such as Cadence and NVIDIA.

“On every benchmark where there’s what I would consider a fair comparison, it seems like reinforcement learning lags behind the state of the art by a wide margin,” says Madden. “For circuit placement, I don’t believe that it’s a promising research direction.”

Learning Network Cable Management - A Small Business Open Frame Rack Build



In this video I build an open frame network rack from scratch, explaining along the way the each step and the reason I am doing it the way that I am. This is intended for a small business network, not a home residence. I made this video for first time builders, so I try not to assume that you have built a lot of these and that you are looking for some general guidance. With an open frame rack, taking control of the giant pile of wires you end up with is more important than ever – both on the front of the rack and the rear where the cables are entering.

Below are the items I used in this video – these are Amazon links that help me out, but of course you don’t have to use them.

You can easily upgrade all of Apple’s AirPods to USB-C using these smart cases

Those of us still rocking AirPods with Lightning ports finally have a way to upgrade them to USB-C that doesn’t require complicated modifications or the cost of completely replacing the case. Engineer Ken Pillonel has created a smart case for older AirPods models that includes a USB-C charging port on the outside.

The protective cases are made from a durable but flexible 3D-printed plastic and can be installed on an AirPods charging case in about 10 seconds. The USB-C port on the outside passes power along to the AirPods’ Lightning port using some added electronics hidden in the base, but the case is also easily removable should direct access to the Lightning port still be needed.

Pillonel’s USB-C Protection Case is available for the original AirPods all the way up to the AirPods Pro 2.

Before buying you’ll want to make sure to double-check that the specific model number listed on your AirPods charging case is compatible with the supported versions specified in each case’s listing.

Pillonel has also come up with a solution for AirPods Max users who don’t want to spend another $549 for Apple’s new USB-C model. His USB-C External Adapter for the original AirPods Max simply plugs into its Lightning port and hangs off the bottom of the right earcup. It’s not quite as elegant as the protective cases, but it’s small enough to be hard to notice while wearing the headphones out and about.

For a few years now, Pillonel has been waging war on Apple’s proprietary Lightning port, which overstayed its welcome as USB-C became commonplace. In 2021, he released an open-source design for upgrading the iPhone X to USB-C and later revealed methods for upgrading AirPods and the AirPods Max to USB-C. Pillonel does sell electronic kits for upgrading Apple’s wireless headphones on your own, but the new cases and adapter don’t require any hardware mods or soldering skills.

WTI rises as traders fear Middle East war

WTI rises as traders fear Middle East war


Oil prices could rally above $200 if Iran’s energy infrastructure is wiped out, analyst says

U.S. crude oil prices rose nearly 2% on Thursday for a third consecutive session of gains, as the market braces for Israel to retaliate against Iran.

The risk of oil supply disruptions increases as fighting in the Middle East intensifies, but OPEC+ is sitting on a large amount of spare crude that could step into the breach, according to Claudio Galimberti, chief economist at Rystad Energy.

U.S. crude oil has gained 5% this week.

Here are Thursday’s energy prices:

  • West Texas Intermediate November contract: $71.53 per barrel, up $1.46, or 2.08%. Year to date, U.S. crude oil is nearly flat.
  • Brent December contract: $75.29 per barrel, up $1.39, or 1.88%. Year to date, the global benchmark has fallen more than 2%.
  • RBOB Gasoline November contract:  $2.0242 per gallon, up 1.93%. Year to date, gasoline has pulled back nearly 4%.
  • Natural Gas November contract: $2.0243 per thousand cubic feet, up 1.98%. Year to date, gas has gained more than 16%.

“This spare capacity is for now preventing runaway prices amid one of the deepest and most pervasive crises in the Middle East in the past four decades,” Galimberti told clients in a Thursday note.

OPEC+ spare capacity would be sufficient to cover a disruption to Iran’s exports if Israel strikes the Islamic Republic’s oil infrastructure as retaliation for Tehran’s ballistic missile attack, said Bjarne Schieldrop, chief commodities analyst at the Swedish bank SEB.

But traders would begin to worry about supply disruptions in the Strait of Hormuz, Schieldrop said. “That would add a significant risk premium to oil,” he told CNBC’s “Street Signs Europe.”

As a consequence, oil prices could surge to $200 per barrel if Israel hits Iran’s oil infrastructure, he said.

C-level executives are a weak point for cybersecurity

Most of us have worked under a less than tech-savvy leader at some point or another, but new research suggests C-suite executives are specifically targeted as they often represent an organizations ‘weakest security link.’

Executives have access to critical information and sensitive data, but a tendency to store it on personal devices, making them a target for hackers, and a survey by GetApp has revealed that 72% of US senior executives have been targeted by cyberattacks in the last 18 months.

It’s parents who are anxious about smartphones, not their children

According to Jonathan Haidt’s bestselling book The Anxious Generation, the proliferation of smartphones and subsequent exposure to social media among children and young people has harmed mental well-being, resulting in an “anxious generation”. Hence Haidt’s title.

However, a closer look at the data reveals that such thinking is aimed in the wrong direction. The meaning and causes of increased rates of anxiety in young people remain complex and unclear. But simply put, when it comes to phones and modern tech, it is often parents who are the overly anxious ones, not their children.

So much of the current discourse about…
