Dual Intel Dynamic Acceleration

Dual Dynamic Acceleration technology boosts CPU performance by means of increasing frequency of any one CPU core when any other CPU core is idle, that is when the other CPU core is in Deep Sleep or lower power state. The CPU may also increase frequency of two of its cores when two other cores are idle. Frequency in Core 2 Quad Mobile CPUs is usually increased by 266 MHz.

This feature was introduced in Intel Core 2 Quad Mobile CPU family and is applicable only to quad-core CPUs. Similar feature in dual-core processors is called Intel Dynamic Acceleration technology. Newer Intel microprocessors based on Nehalem core utilize improved version of IDA called Turbo Boost Technology.
