Intel Core

Intel Core is a introduced in January 2006, 32 -bit processor family manufacturer Intel, which has been developed for use in notebook computers (notebook processor). The processor family is used in the Centrino and Centrino Duo platform. It was replaced by the Intel Core 2

General

With the launch of this processor family, Intel replaced by its brand name "Pentium", which has been used for all high-order processors in the house Intel and introduced as an additional brand name " Core". The models are titled with a CPU core as Core Solo, the variants with two CPU cores ( dual core processor ) than Core Duo.

However, all processors are based on the same The first, codenamed " Yonah " which Intel's native dual-core processor represents.

Architecture

Like the Pentium M processors use the Intel Core processors, a highly modified version of the Intel P6 architecture (and not the NetBurst microarchitecture of the Pentium 4). In contrast to Desktoppendant Intel Pentium D are the Intel Core already combines both cores on one die. The architecture is characterized by relatively low heat generation and low power consumption and high computing power, but does not provide 64- bit extension.

Compared to its predecessor, the Intel Virtualization Technology and the command extension SSE3 was added, further exists on Intel Core also a variant with two processor cores. The L2 cache is available only once for the two cores ( shared cache). Speedstep works for the dual-core variant separately for both cores, so that the power consumption can be maintained at a very low level. In the " Enhanced Deeper Sleep " mode, the processor can write the contents of the L2 cache to the main memory and thus turn off the L2 cache completely. There is also a newer manufacturing technology (65 nm ) is used, requires " Yonah ", the only developed core at the same clock frequency less energy than the last Pentium M core " Dothan "; the dual-core version is the total power just above as " Pentium M" selling predecessor, " Dothan " with only one core.

Successor

The authorization granted by Intel complete detachment NetBurst architecture, which were used among others by the Intel Pentium D, perform the Core 2 processors. These have the Intel Core microarchitecture, which was developed based on the Intel Pentium M and Intel Core.
