AMD Moves Desktop Processors to 65 Nanometers

AMD began shipping desktop processors manufactured on a 65 nm process in late 2006, moving beyond the 90 nm technology used in earlier Athlon 64 chips. Semiconductor “process nodes” are not a direct measurement of one transistor dimension, but the move represented a new generation of manufacturing technology.

Shrinking transistors can reduce capacitance and power use while allowing more circuitry to fit into the same die area. For AMD, 65 nm manufacturing was also important economically: smaller dies can increase the number of chips produced from a silicon wafer if yields are good.

The transition came during intense competition with Intel’s new Core 2 processors. Manufacturing improvements alone could not solve an architectural performance gap, but they were essential for keeping power consumption, die cost, and future transistor budgets under control. Modern CPU competition still depends on this combination of architecture and process technology.
