What is 45nm Transistor Technology?
45nm transistor technology is one of the biggest advancements in transistor design, in which a dramatically different material is used to build microscopic 45 nanometer (nm) transistors with drastically reduced electrical leakage. Compared to today’s 65nm technology, 45nm transistor technology nearly doubles the transistor density and reduces transistor-switching power by 30 percent. This allows Intel to create processors with new high performance and power efficient features, like the Intel SSE4 instructions and microarchitecture enhancements in Penryn.
