You may remember our post about how transistors work, featuring an EngineerGuy video—his videos give great explanations. At least knowing what a transistor is is pretty important, because they’re the foundation for just about every piece of technology we’ve got.
Well, big news in the transistor world: Intel has just announced a 3d transistor design, which is supposed to be faster and much more energy-efficient than normal, 2d transistors.
A more detailed rundown of trigate transistors is at Ars Technica. Pretty interesting writing, so give it a read.
This can mean something big for you. If you plan on being an electrical engineer, this kind of information is vital as it will likely be the foundation of a lot of the work you do as an adult—a lot of ECE graduates work on designing and making computer chips. And if not, it means computers are going to get even smaller and more efficient—possibly cheaper.
Read what I read (in the order I found them):
- Article from Physorg.
- The New York Times covered this! Here’s a really useful graphic they’ve generated which helps explains things.
- Treehugger covered this–it’s a breakthrough in energy efficiency. 50% greater efficiency means your cellphone would last almost twice as long (minus things like audio and display power)
- Ars Technica’s article. Linked-to above. This one has a good rundown on how the upgrade works. The article is two pages long so don’t miss the link.
- Intel’s newsroom article on the announcement.
- The Intel page on 3d transistors. It’s a massive information dump, with links to several pdf files about their work.
