“Intel’s latest processor architecture, codenamed Ivy Bridge, is its previous one, Sandy Bridge, shrunk,” Simon Crisp reports for The Register.
“Sandy Bridge chips, marketed as second-generation Core i CPUs, were produced using a 32nm process. Ivy Bridge is 22nm,” Crisp reports. “Actually, there’s a little bit more to it than that.”
Crisp reports, “At the heart of the new fabrication process is the Intel’s Tri-Gate transistor technology, which the chip giant is calling the world’s first ‘3D’ transistor. Traditionally, the transistors in a processor or any other silicon chip are to all intents and purposes flat, so they’re considered to be 2D even though they’re not literally so. The new Tri-Gate transistors have a fin that stands vertically up off the silicon substrate, hence the 3D tag.”
