Two infrastructure companies from Chile and Singapore are preparing to build the first submarine internet cable to dock on the shores of Antarctica.

The product of a partnership between Desarrollo País and H2 Cable, a subsidiary of BW Digital, the Humboldt Cable cable will run 15,000km from Chile to Australia, with offshoots landing in New Zealand and two islands off the Chilean mainland.

Significantly, however, there will also be a 2,000km branch connecting Antarctica, which is currently the only continent that does not benefit from the increased speeds and capacity that undersea cables afford.

Connecting Antarctica

According to a research paper from 2021, cited by The Register, Antarctica’s Scott Base and McMurdo Station currently suffer from an extreme lack of networking capacity, “insufficient to even be considered broadband.”

“A summer population of up to 1,000 people share what is equivalent to the connection enjoyed by a typical family of three in the United States,” wrote Peter Neff, who authored the report.

The arrival of the Humboldt Cable on Antarctic shores would minimize the reliance on slow and patchy satellite internet, offering those living and working in the area access to a hardwired connection for the first time.

Presumably, the new connection will be of particular benefit to researchers operating out of the area, who might currently struggle to pass large quantities of data to collaborators elsewhere in the world, for example.

The cable will also be of great significance for the residents of South America, who will benefit from a significant increase in capacity.

"The Humboldt Cable will be the most significant piece of subsea infrastructure connecting South America, paving the way for deployment of essential datacenters, AI and other data-driven technologies to help to put Chile on the digital map," said H2 and Desarrollo País.

As it stands, the route and schedule have been formalized, but the two companies are still courting potential investors before launching procurement and engaging with stakeholders at the anchor locations.

Value Electronics, an A/V retailer located just outside New York City, has been conducting an annual ‘TV Shootout’ for nearly two decades. The Shootout traditionally gathers a panel of TV testing experts and puts them in front of the best 4K TVs to decide which one is the absolute best – an honor that Sony earned this year for its A95K QD-OLED model.

With the rise of 8K TVs, the Value Electronics test has expanded in 2022 to include a separate test for that category, with LG’s Z2 OLED model taking the 8K crown at this year’s Shootout.

4K TVs competing in the 2022 TV Shootout: 

  • LG G2 Gallery Series OLED
  • Samsung QN95B Quantum Dot mini-LED
  • Samsung S95B QD-OLED
  • Sony XR-A95K QD-OLED (winner)
  • Sony XR-X95K mini-LED

8K TVs competing in the 2022 TV Shootout:

  • LG Z2 OLED (winner)
  • Samsung QN900B Quantum Dot mini-LED
  • Sony XR-Z9K mini-LED TV

To create an even playing field for the evaluation, each TV is first adjusted by a professional TV calibrator. The sets are then arrayed side by side along with a 32-inch Sony professional broadcast reference monitor, and fed test patterns and regular movie scenes over a video distribution network. This arrangement allows for the expert participants to evaluate the TVs simultaneously, with their votes tabulated to determine the winner in each category.

The evaluations covered standard high-definition content displayed in both a bright and dark viewing environment, and 4K high dynamic range (HDR) in a dark viewing environment. For the HDR tests, each set was further evaluated for “tone mapping,” or its performance when scaling the full contrast range of incoming HDR programs to the display's maximum brightness capability.

Is QD-OLED the best TV tech? 

The Sony QD-OLED had a first place standing in each testing category in the Value Electronics Shootout, and was followed closely by Samsung’s own S95B QD-OLED model. That result says quite a bit about the future for the new TV technology, which combines the best qualities of OLED with the Quantum Dots tech used by QLED TVs.

LG’s G2 OLED also closely trailed Sony’s QD-OLED in the 4K TV test. This tells us that regular OLED is still a viable contender, especially models like LG’s G2 and C2 that use the company’s higher brightness ‘evo’ panels. In fact, the G2 bested the Sony A95K in the peak brightness and 4K picture detail categories of the Value Electronics test.

The LG Z2 OLED model was also the winner in the 8K category, which proves that OLED can be expanded to even higher resolutions and greater screen sizes (the Z2 is only available in 77- and 88-inch options) and still successfully compete with the best QLED TVs.

What’s really interesting about the results of this test is the pricing aspect. At around $4,000 / £3,499 in a 65-inch screen size, Sony’s award-winning XR-A95K is one of the most expensive 4K TVs you can buy – not surprising given that it uses next-gen display tech. 

But the Samsung S95B which uses the same display technology and was nipping at the Sony QD-OLED’s heels in the Value Electronics evaluation, is only around $2,600 / £2,799, making it the test’s real value champ.

You won’t go wrong with any of the sets that participated in this test, since they are all top models from top brands. But if getting a good deal is also of interest, you may want to do further research before simply forking over hard-earned cash for an award-winning flagship TV.

Silicon might be the de facto standard for today's computing, but it might be due for a change if new research from MIT, the University of Houston, and other institutions is to be believed.

Cubic boron arsenide, a chemical compound cooked up from a combination of boron and arsenic, could apparently be a better semiconductor, bypassing some of the weaknesses of silicon when it comes to heat sensitivity. 

In fact, according to research published in Science,  Cubic boron arsenide has the "third-best thermal conductivity of any material — next to diamond and isotopically enriched cubic boron nitride".

Is this the future?

The research said that more work would be needed to determine whether cubic boron arsenide can be "made in a practical, economical form, much less replace the ubiquitous silicon". 

But even in the near future, the material could find "some uses where its unique properties would make a significant difference" according to the researchers. 

That being said, the research outlined the vast potential that the compound has.

Cubic boron arsenide is apparently much more accommodating to “holes” — electrons’ positively charged counterparts.

The lower heat sensitivity of cubic boron could also make a huge difference.

“Heat is now a major bottleneck for many electronics,” said MIT postdoc Jungwoo Shin who co-authored the paper. “Silicon carbide is replacing silicon for power electronics in major EV industries including Tesla, since it has three times higher thermal conductivity than silicon despite its lower electrical mobilities". 

"Imagine what boron arsenides can achieve, with 10 times higher thermal conductivity and much higher mobility than silicon. It can be a game changer.”

It's not just cubic boron arsenide that is threatening to overtake silicon one day.

Researchers from the University of Illinois built 4-bit and 8-bit processors entirely out of plastic, which apparently had an 81% success rate, at least for the 4-bit models. 

It's important to note that silicon never really had a monopoly in the world of semiconductors anyway.

Gallium arsenide, built from gallium and arsenic, is widely used in lasers as an alternative to silicon.

Allstate Car Insurance Review for August 2022 - CNET

Latest Tech News

There's finally some news on Intel Arc Alchemist's release date, but not the kind that anybody outside of Nvidia and AMD really wanted to hear: Arc Alchemist and Battlemage might get the ax entirely over unfixable hardware flaws that are kneecapping their performance, and it's threatening to scrap Intel's entire Arc discrete graphics line.

This report comes from YouTuber Moore's Law is Dead, and it is a doozy, full of internal politics, bitterness, and recriminations at Intel over the company's graphics unit being unable to actually deliver the discrete graphics cards that have been hyped up for more than a year.

I highly suggest you watch the video for all the tea, but the key takeaway is that internal sources at Intel told Moore's Law is Dead that there is a potentially unfixable hardware flaw in the Arc Alchemist GPU that the graphics unit had hoped to address using a driver fix, but that fix isn't working. That's the hardware challenge, reportedly, and it might extend to Battlemage as well. If this is true, then it definitely would explain why the Intel Arc launch has been, well, strange.

Where things get real messy is that the Intel Arc graphics unit has been doing PR for Arc Alchemist cards that Intel told investors would have launched to western markets by the end of the second quarter of this year. We are now in Q3, the cards have not launched, and Intel insiders outside of the graphics unit are angry that the graphics unit is doing PR saying that cards are ready when they do not appear to be ready at all.

On top of that, there are apparently issues with Intel AIB partners who, according to a purportedly leaked presentation, were lined up to produce Intel Arc cards starting at the end of July. Moore's Law is Dead is saying that none of the board partners he's spoken with have any idea what is going on, and the AIBs are not at all happy with the situation.

Finally, cue Pat Gelsinger, Intel's CEO, who is reportedly now looking into whether the entire Arc discrete graphics project should just be canceled. As Moore's Law is Dead highlights in the video, there were some strong hints of this frustration during Intel's earnings call this week where Gelsinger acknowledged the disappointing earnings and said that while the global chip shortage was still very much an issue, problems of "execution" on Intel's part also contributed to Intel's falling far short of earnings expectations for Q2.

So, that is more or less the report that Moore's Law is Dead presented, and we have not independently confirmed anything ourselves, though we have reached out to Intel for comment and will update this story if and when we hear back from the company.

So, um, when exactly are we going to see these cards? Asking for a friend

It's still too soon to tell what exactly is happening with Intel Arc, but Moore's Law is Dead's report isn't coming out of nowhere. Intel Arc Alchemist is more than a month late from its target launch date in the US, and the smattering of cards we have seen in the wild have been bizarrely inconsistent, with performance throttling from single lines of code to the head-scratcher that Intel's first discrete graphics card was going to launch in China and India first.

Fair enough, those are two of the largest consumer markets in the world, and China has more than enough tech heads that want to get their hands on some Intel cards, too, but there's no way to shake an uneasy feeling about all this. This doesn't feel like a well-planned product launch, and the recent PR appearances by some Intel reps on the graphics card team invariably fail to answer the question everybody is asking, which is when are these cards coming out? 

Sure, they're available in China and India, so they are technically "out", but I mean globally. That's a question Intel can't seem to answer right now, and it's a damned shame if there ever was one.

Budget builders can't catch a break

Earlier this week, I wrote about the problem of semiconductor manufacturers like Nvidia, AMD, and, yes, Intel, pursuing increasingly more powerful hardware in an arms race with rivals and how that is having very real consequences in the real world. The wholesale abandonment of any pretense towards energy efficiency in all but the most basic Chromebook processor is disturbing.

Not as bad but still awful is the pricing out of an increasing number of people, mostly gamers but also academics and researchers who actually do need high-performance GPUs for scientific work, and who are simply not the target consumers for these cards anymore. 

There are rumors that Nvidia's RTX 4090, when it launches later this year, will cost less than the RTX 3090. That's a nice start, but the RTX 3090 costs $1,499. Will the RTX 4090 cost $1,449? $1,299? You know what else costs $1,499? A 3-credit-hour graduate course at the City University of New York-Brooklyn College. The cost of the RTX 3090 was obscene, frankly, when it launched, and it remains so.

It used to be you could rely on AMD to come in with a lower-cost option for the rest of us who couldn't afford a GeForce card anymore, but that ship is sailing, too. There is still value to be found among graphics cards out there, which is why the Nvidia RTX 3060 Ti is at the top of our best graphics card list, but that herd is thinning rather quickly.

That, ultimately, was my hope for Intel Arc. As a newcomer to the graphics card cold war between Nvidia and AMD, there was room for Intel to sweep in with a solid budget to lower-midrange lineup and clean up on that cost-conscious-friendly market. I hope Moore's Law is Dead turns out to be dead wrong on this, but it's looking rather iffy out here for all the gamers stuck on aging hardware like the RTX 1050 and AMD RX 470.

If Intel does end up shelving or axing Arc entirely, it will be a real blow to budget-minded gamers and builders out there, and the budget side of things could really use a solid win these days.
