Intel CPUs for mobile and compact PCs

Intel processors for mobile PCs - Pentium M or Celeron M - are inseparably linked with the integrated Centrino platform for mobile PCs promoted by the company for several years, which includes Intel's best technologies for notebook PCs.

Dual-core Intel Core 2 Duo CPUs for mobile and compact PCs

From a certain time, the new Intel Core architecture has been topical for all the market sectors - mobile, desktop, and server systems. Having inherited the philosophy of efficient power consumption first implemented in Intel Pentium M for mobile PCs with the working name Banias, owing to new technologies and implementation of some developments of the new NetBurst architecture, the new generation architecture has improved the ratings. Here are the key innovations of Intel's new CPU architecture:

The Intel Wide Dynamic Execution technology is to provide a greater number of instructions executed per cycle, thus improving the efficiency of running applications and reducing the power consumption. Each core of the processor that supports this technology is now able executing up to four instructions simultaneously using the 14-stage pipeline.
The Intel Intelligent Power Capability that enables specific components of the chip only when needed allows to achieve a substantial reduction in the power consumption of the system on the whole.
The Intel Advanced Smart Cache technology implies using a unified L2 cache memory common for all the cores, whose joint use allows to cut down the power consumption and raise the performance. At the same time, one of the processor cores may use up the whole volume of the cache memory whenever needed, with the other core disabled dynamically.
The Intel Smart Memory Access technology increases the system performance due to the reduced memory response time and thus optimized bandwidth of the memory subsystem.
The Intel Advanced Digital Media Boost technology allows processing all the 128-bit SSE, SSE2, and SSE3 commands widely used in multimedia and graphic applications in one cycle, which increased their speed of execution.

Intel Core 2 Duo with the 2-core Merom design aimed at mobile and economy PCs are represented by the Ò series whose TDP is rated within 25 to 49 W.

Dual-core Intel Core 2 Duo Low Voltage CPUs for mobile and compact PCs

Dual-core Intel Core 2 Duo for mobile PCs are also represented by the economy Low Voltage series with the index L, which means the TDP is within 15 to 24 W.

Dual-core Intel Core Duo CPUs for mobile and compact PCs

Dual-core Intel Core Duo for mobile PCs which are a component of the mobile platform Intel Centrino Duo are made on the base of the Yonah architecture following the norms of the 65-nm process technology.

The processors are remarkable for parallel execution of task branches on two cores with distributed CPU resources, offer 32 K L1 cache for instructions and L2 Intel Smart Cache of 2 MB capacity with support for the Advanced Transfer Cache architecture that provides efficient usage of cache memory and the CPU bus to improve the performance of the 2-core system and reduce the power consumption; the Intel Digital Media Boost technology that optimizes fetching of Streaming SIMD Extensions 2 (SSE2) and Streaming SIMD Extensions 3 (SSE3).

Intel Core Duo processors support the power-consumption optimized FSB = 667 MHz, as well as Intel Dynamic Power Coordination with the Dynamic Bus Parking feature to coordinate the performances of the cores @on demand". The Intel Dynamic Power Coordination allows each core to switch to the Halt, Stop Clock, and Deep Sleep states dynamically, and in the 2-core mode – synchronously to the Deeper and Enhanced Deeper Sleep modes. The distributed logic of the chip's power consumption control coordinates operation of the Enhanced Intel SpeedStep mode as well as switching between the C-states, which results in low supply voltage operation for Core Duo chips and minimum heat dissipation in the active state

Final words

In the first approximation, this is the reference material on Intel CPUs for desktop and mobile PCs. Let's hope it will be complemented with details, illustrations and will help our readers clear up the matter when choosing among a lot of offerings.

Next in the queue are reference materials on CPUs by AMD and VIA. As ever, we are looking forward to your letters of criticism and suggestions.
