Intel 4004, the first CPU, is 40 years old today

Sebastian Anthony, ExtremeTech.com

Four decades ago today — November 15, 1971 — Intel placed an advertisement for the first single-chip CPU, the Intel 4004, in Electronic News. Designed by the fantastically-forenamed Federico Faggin, Ted Hoff, and Stanley Mazor, the 4004 was a 4-bit, 16-pin microprocessor that operated at a mighty 740KHz — and at roughly eight clock cycles per instruction cycle (fetch, decode, execute), that means the chip was capable of executing up to 92,600 instructions per second. We can’t find the original list price, but one source indicates that it cost around $5 to manufacture, or $26 in today’s money.

The 4004 used state-of-the-art Silicon Gate Technology (SGT) PMOS logic — a technique that Faggin perfected at Fairchild Semiconductor in 1968 — the world’s first metal-oxide-silicon (MOS) process. This breakthrough allowed the 4004 to have no less than 2,300 transistors and a feature size of 10 micron. By comparison, there are half a billion transistors in a Sandy Bridge chip, and each one is just 0.032 micron. Considering a human hair is around 100 micron, the 4004 was still rather impressive — but irrespective of feature size or transistor count, the fact that it was carved from a single piece of silicon is what made the 4004 truly spectacular. Faggin was so proud of his creation that he even signed the chip “FF”, which you can see in the top right of the image below.

Difference Engine: Re-inventing the web

By N.V., The Economist

HAVING just taken up a new assignment in California in the early 1990s, following a five-year hiatus covering the financial roller-coaster of Japan, your correspondent was embarrassed to be asked each time he interviewed sources in Silicon Valley what was his employer’s web address—ie, its Universal Resource Locator or URL.

For the first few months, he mumbled something about the core competency of newspapers and magazines being their well-honed ability to spread the word around the world overnight via print, not bits and bytes. When he could take the cajoling no longer, he got permission (though no money) from the higher-ups in London to create The Economist’s first web presence in his spare time.

Not counting those evenings and weekends, the total cost of building The Economist’s first website came to $120—mostly spent on getting graphics scanned at Kinko’s. Hosting the site, on EarthLink, cost $20 a month. To your correspondent’s amazement, AOL subsequently ranked his botch-up as one of the top ten news sites in the world, ahead of Time Warner’s “Pathfinder” website, which reputedly cost $140m to build.

Slicing an Apple

By P.K., The Economist

APPLE doesn’t make the iPhone itself. It neither manufactures the components nor assembles them into a finished product. The components come from a variety of suppliers and the assembly is done by Foxconn, a Taiwanese firm, at its plant in Shenzhen, China. The “teardown” graphic below, based on data from iSuppli, a market-research firm, shows who makes what inside the iPhone, and how much the various bits cost. Samsung turns out to be a particularly important supplier. It provides some of the phone’s most important components: the flash memory that holds the phone’s apps, music and operating software; the working memory, or DRAM; and the applications processor that makes the whole thing work. Together these account for 26% of the component cost of an iPhone.

This puts Samsung in the somewhat unusual position of supplying a significant proportion of one of its main rival’s products, since Samsung also makes smartphones and tablet computers of its own. Apple is one of Samsung’s largest customers, and Samsung is one of Apple’s biggest suppliers. This is actually part of Samsung’s business model: acting as a supplier of components for others gives it the scale to produce its own products more cheaply. For its part, Apple is happy to let other firms handle component production and assembly, because that leaves it free to concentrate on its strengths: designing elegant, easy-to-use combinations of hardware, software and services.

It Knows

Daniel Soar, London Review of Books

This spring, the billionaire Eric Schmidt announced that there were only four really significant technology companies: Apple, Amazon, Facebook and Google, the company he had until recently been running. People believed him. What distinguished his new ‘gang of four’ from the generation it had superseded – companies like Intel, Microsoft, Dell and Cisco, which mostly exist to sell gizmos and gadgets and innumerable hours of expensive support services to corporate clients – was that the newcomers sold their products and services to ordinary people. Since there are more ordinary people in the world than there are businesses, and since there’s nothing that ordinary people don’t want or need, or can’t be persuaded they want or need when it flashes up alluringly on their screens, the money to be made from them is virtually limitless. Together, Schmidt’s four companies are worth more than half a trillion dollars. The technology sector isn’t as big as, say, oil, but it’s growing, as more and more traditional industries – advertising, travel, real estate, used cars, new cars, porn, television, film, music, publishing, news – are subsumed into the digital economy. Schmidt, who as the ex-CEO of a multibillion-dollar corporation had learned to take the long view, warned that not all four of his disruptive gang could survive. So – as they all converge from their various beginnings to compete in the same area, the place usually referred to as ‘the cloud’, a place where everything that matters is online – the question is: who will be the first to blink?

If the company that falters is Google, it won’t be because it didn’t see the future coming. Of Schmidt’s four technology juggernauts, Google has always been the most ambitious, and the most committed to getting everything possible onto the internet, its mission being ‘to organise the world’s information and make it universally accessible and useful’. Its ubiquitous search box has changed the way information can be got at to such an extent that ten years after most people first learned of its existence you wouldn’t think of trying to find out anything without typing it into Google first. Searching on Google is automatic, a reflex, just part of what we do. But an insufficiently thought-about fact is that in order to organise the world’s information Google first has to get hold of the stuff. And in the long run ‘the world’s information’ means much more than anyone would ever have imagined it could. It means, of course, the totality of the information contained on the World Wide Web, or the contents of more than a trillion webpages (it was a trillion at the last count, in 2008; now, such a number would be meaningless). But that much goes without saying, since indexing and ranking webpages is where Google began when it got going as a research project at Stanford in 1996, just five years after the web itself was invented. It means – or would mean, if lawyers let Google have its way – the complete contents of every one of the more than 33 million books in the Library of Congress or, if you include slightly varying editions and pamphlets and other ephemera, the contents of the approximately 129,864,880 books published in every recorded language since printing was invented. It means every video uploaded to the public internet, a quantity – if you take the Google-owned YouTube alone – that is increasing at the rate of nearly an hour of video every second.

The Reluctant Luddite

Dirk Olin, Dartmouth Alumni Magazine

Picture the inside of the campus computer center, circa 1970. No smartphones, no Internet, just a bunch of workstations with teletype machines hooked into mainframes, clickety-clacking away as the machines’ typeballs smack their fonts onto rolls of paper in staccato bursts.

Amid the computer nerds there sits an 11-year-old boy with black curly hair hunched over a keyboard. On weekend mornings, after his family had driven up from central Connecticut to dad’s alma mater for a football game, little Nick Carr would play a different version of the game, punting and passing his way through a rudimentary computer version in which he punched 1 to call a “simple run” or 4 for a “long pass.” He’d hit return and then wait for the algorithm to spit back how many yards had been gained or lost. It wasn’t just for fun—“I also actually figured out the early version of word processing they had on the system,” Carr recalls.

Fast-forward to Carr’s matriculation in the fall of 1977. The whiz kid gravitates not to computer sciences, but to English. This was leavened by an affinity for the Sex Pistols and the Dead Boys: Carr hosted a midnight punk show on WFRD. “That was the only time they’d let me do it,” he recalls. “Some people were a little nervous about it.”

The Utterly Amazing Future Awaiting High-Tech Humanity: An Interview With Dr. Michio Kaku, The Author Of “Physics Of The Future”

By Evert Cilliers aka Adam Ash, 3 Quarks Daily

If you’re interested in the future, or if you’re a sci-fi freak, or a geek, or a lover of science, or a transhumanist, or a singularity nut, or a fan of Bladerunner or 2001: A Space Odyssey, or all of these (like me), this book is for you.

Author Dr. Michio Kaku gives us three futures to contemplate in his comprehensive overview of everything science is doing to take us into a future that is unimaginably different, weird and wonderful:

a) where we will be in the near term (present to 2030)

b) in midcentury (2030 to 2070)

c) in the far future (2070 to 2100).

Dr. Kaku’s predictions are not only informed by the fact that he’s a supersmart scientist himself (with the rare ability to explain abstruse science to ignorant amateurs like me), but that he has personally visited with more than 300 of the relevant scientists and hung out at their laboratories where our future is being designed right now.

Here’s a brief list of some of his more startling predictions:

1. We will be operating internet computers that are lodged in contact lenses by blinking our eyes and making hand movements Theremin-style in the empty air.

2. We will have the ability to bring back the woolly mammoth and Neanderthal man, although Dr. Kaku is not so sure that we’ll be able to bring back any dinosaurs.

Over the High-Tech Rainbow

Sue Halpern, New York Review of Books

Three days after Apple’s new iPhone, the 4S, went on sale, the company announced that over four million devices had been sold—a record. It’s safe to say that most of these sales were not made to people who were drawn to the phone’s new and improved physical form, since the design of the iPhone 4S was pretty much a reiteration of last year’s model, the iPhone 4, which sold a record 1.7 million in its first three days. And while some of those four million sales might have been made because of the newer phone’s faster processing speed and improved camera, these were probably not major draws either, since other phones on the market already offered both features.

The real magnet was Apple’s inclusion of Siri, a natural-language processing, artificial-intelligence driven “personal assistant” that interprets and executes a user’s verbal commands like “Make me a reservation for four at the best tapas bar in Dallas” and answers questions about the weather (“Do I need an umbrella?”) and, essentially, allows one to interact with the Internet without typing a word. But you already know this: most major news outlets breathlessly live-blogged the iPhone 4S launch as if it actually mattered to the world at large, and Siri demo videos are now all over the Internet.

As you also know, the day after the iPhone 4S was launched, Apple’s founder and resident seer, Steve Jobs, died. One of the most popular Jobs quotes circulating in the days after his death was one that he attributed to hockey great Wayne Gretzky: “A good hockey player plays where the puck is. A great hockey player plays where the puck is going to be.” After three days of record iPhone 4S sales, there’s no better example of playing to where the puck is going to be than Siri. There are other “personal assistant” smart phone apps available. Indeed, before Apple removed it from its App Store, Siri was one of them. But who knew that consumers wanted Siri baked into their phone, and into Apple’s servers, which stores all previous “conversations,” so that Siri gets more and more familiar with its “boss” all the time? Steve Jobs, obviously.
