Five paths for Moore's Law



Loosely translated, predictions in Moore’s Law mean that every 18 to 24 months, you can buy a faster computer with the same amount of money. Moore’s Law predicted that the number of transistors in a given die area would double every two years, and that making chips would get progressively cheaper.

But a debate is raging around just how long Moore’s Law will last. On the 50th anniversary of Moore’s Law, IDG News Service asked top industry analysts to share their opinions on where the famous observation is headed, and how long it will remain relevant.

G. Dan Hutcheson, CEO and Chairman of VLSI Research

“The most important direction that Moore’s Law sends the world in is not more transistors-per-chip. It’s what those transistors enable people to do that sets the direction. Chips are blank canvases for designers to create products that delight us, allow us to create, communicate, and most important of all ... extend the power of our brains so we create things like the latest drugs. It has also created US$13 trillion dollars in economic value, an amount that’s equal to a third of the U.S. economy. Moore’s Law saved 33-gigawatts of power [last year].

“As for how long Moore’s Law will last, no one knows. Even in [Gordon Moore’s] first paper, he would only speculate 10 years out. At 50, we still have the same visibility: 10 years. Gordon asked Stephen Hawking what he the thought the limit was. Hawking said the ultimate limit was the speed of light and the size of a single atom. So, we have a long ways to go.”

“When Moore’s Law inevitably comes to a close, what we will see is probably going to look an awful lot like what is happening today: the most expensive transistors will go to places where they are most economically effective, which is into servers, while cheaper and fewer transistors go to lower-end client computing devices like phones and tablets. Rest assured that even when Moore’s Law is over, growth in computing performance is limited only by the willingness of customers to pay for more speed.”




Kevin Krewell, senior analyst at Tirias Research


“What’s still driving client computing forward is the demand for higher resolution displays, longer battery life, and device thinness. What this all means is that the drivers of Moore’s Law are fracturing—microcontrollers and sensors will jump off to save costs, big chips will become increasingly pricier to make, and client computing will drive massive power reductions to make capable, but incredibly thin, personal devices. The role of Moore’s Law is to keep driving the industry forward, no matter how it’s done, nor the costs—and for that, I see a long life for it ahead as symbolic driver.”

Rob Lineback, senior market research analyst at IC Insights

“We’ve seen a half-dozen or so other technology tricks being leveraged in driving down cost, increasing performance, or adding functionality in smaller spaces. Advancements today are coming from multi-chip assemblies, wafer-level packaging, and other non-Moore’s Law aspects that go beyond smaller feature sizes that drove advancements in the integrated-circuit industry during the 1970s to the last decade. Some have called it ‘more than Moore’ technology.

“Moore’s Law is more important to some types of integrated circuits than others, such as microprocessors and memories versus system-on-chips and sensors. More of the semiconductor industry is diverging—splitting apart, with some of it moving further away from Moore’s Law—while other parts continue to need the steady drum beat of device shrinks, like 64-bit application processors in cellphones.”
