Core Duo

Core Duo

Intel's first dual-core chip for Centrino laptops. Introduced in early 2006, the Core Duo CPU was also the first x86 chip used in the Macintosh, as Apple transitioned from the PowerPC to the x86 CPU family (see MacBook Pro). Note that Core Duo and Core 2 Duo chips are not the same (see Intel Core).

The Core Duo is a dual-core chip that dramatically reduced power consumption over previous CPU chips. For example, when the laptop is placed in standby mode (sleep mode), the Core Duo flushes its cache to main memory because dynamic RAM chips use less power to retain content than the static RAM cache chips. See dual core, Centrino, Intel Core and Core 2.

Core Solo
The Core Solo CPU is the single-core version of the Core Duo. It works with the same 945PM and 945GM chipsets introduced for the Core Duo.
