Intel and IBM Break the 45-Nanometer Barrier

Because the new 45-nanometer transistors from IBM and Intel are smaller, they can switch on and off more quickly, roughly 300 billion times per second in Intel’s case. Intel has code-named its new 45-nanometer chips Penryn and plans to produce next-gen Core 2 Duo, Core 2 Quad, and Xeon chips this year, all with Penryn designs
