Moore's Law Blowout Sale Is Ending, Says Broadcom CTO
itwbennett writes "Broadcom Chairman and CTO Henry Samueli has some bad news for you: Moore's Law isn't making chips cheaper anymore because it now requires complicated manufacturing techniques that are so expensive they cancel out the cost savings. Instead of getting more speed, less power consumption and lower cost with each generation, chip makers now have to choose two out of three, Samueli said. He pointed to new techniques such as High-K Metal Gate and FinFET, which have been used in recent years to achieve new so-called process nodes. The most advanced process node on the market, defined by the size of the features on a chip, is due to reach 14 nanometers next year. At levels like that, chip makers need more than traditional manufacturing techniques to achieve the high density, Samueli said. The more dense chips get, the more expensive it will be to make them, he said."
Used to be you used to have to upgrade every 2 years. Now you really have to upgrade every 5 or 7 years. Once every 10 years sounds pretty good to me. As the pace of computer innovation slows, less money has to go towards upgrades. Computers are now more like appliances, you run them down until they physically break.
Of course if you manufacture computers or work in IT, then such a proposition is horrible as a long product lifecyle means less money coming to you. As a consumer, I like it because I no longer have to shell out hundreds of dollars every other year to keep my computers usable.
Well, we had a good run. 99% of the computing needs of 99% of the people can be met by the existing chips electronics. For most people network and bandwidth limits their ability to do things, not raw computing power or memory. So Moore's observation (it ain't no law) running out of steam is no big deal. Of course the tech companies need to transition from selling shiny new things every two years to a more sedate pace of growth.

If that's true, we can only hope that the exponential bloating of software stops as well. Software has been eating the free lunch Moore was providing before it got to the users; the sad reality is that the typical end-user hasn't seen much in the way of performance improvements - in some cases, common tasks are even slower now than 10 years ago.
Oh sure, we defend it by claiming that the software is "good enough" (or will be on tomorrow's computers, anyway), and we justify the bloat by claiming that the software is better in so many other areas like maintainability (it's not), re-usability (it's not), adherence to "design patterns" (regardless of whether they help or hurt), or just "newer software technologies" (I'm looking at you, XAML&WPF), as if the old ones were rusting away.
more transistors per unit area on a chip is worthless atm. you can have a million cores on a processor, but it will still be slowed down dramatically due to issues with parallelism. someone needs to find a way to increase parallel processor speed.
I see many emerging technologies that promise further great progress in computing. Here are some of them. I wish some industry people here could post some updates about their way to the market. They may not literally prolong the Moore's Law in regards to the number of transistors, but they promise great performance gains, which is what really matters.
3D chips. As materials science and manufacturing precision advances, we will soon have multi-layered (starting at a few layers that Samsung already has, but up to 1000s) or even fully 3D chips with efficient heat dissipation. This would put the components closer together and streamline the close-range interconnects. Also, this increases "computation per rack unit volume", simplifying some space-related aspects of scaling.
Memristors. HP is ready to produce the first memristor chips but delays that for business reasons (how sad is that!) Others are also preparing products. Memristor technology enables a new approach to computing, combining memory and computation in one place. They are also quite fast (competitive with the current RAM) and energy-efficient, which means easier cooling and possible 3D layout.
Photonics. Optical buses are finding their ways into computers, and network hardware manufacturers are looking for ways to perform some basic switching directly with light. Some day these two trends may converge to produce an optical computer chip that would be free from the limitations of electric resistance/heat, EM interference, and could thus operate at a higher clock speed. Would be more energy efficient, too.
Spintronics. Probably further in the future, but potentially very high-density and low-power technology actively developed by IBM, Hynix and a bunch of others. This one would push our computation density and power efficiency limits to another level, as it allows performing some computation using magnetic fields, without electrons actually moving in electrical current (excuse me for my layman understanding).
Quantum computing. This could qualitatively speed up whole classes of tasks, potentially bringing AI and simulation applications to new levels of performance. The only commercial offer so far is Dwave, and it's not a classical QC, but so many labs are working on that, the results are bound to come soon.

Embedded system programmers are the only real programmers anymore.
Do not look at laser with remaining good eye.
Only if they can work in parallel without needing information from each other.
