Processor—Power Management

Package C2 State

Package C2 state is an internal processor state that cannot be explicitly requested by software. A processor enters Package C2 state when:

•All cores and graphics have requested a C3 or deeper power state; however, constraints (LTR, programmed timer events in the near future, and so on) prevent entry to any state deeper than C 2 state. Or,

•All cores and graphics are in the C3 or deeper power states, and a memory access request is received. Upon completion of all outstanding memory requests, the processor transitions back into a deeper package C-state.

Package C3 State

A processor enters the package C3 low-power state when:

•At least one core is in the C3 state.

•The other cores are in a C3 state or deeper power state and the processor has been granted permission by the platform.

•The platform has not granted a request to a package C6 or deeper state, however, has allowed a package C6 state.

In package C3 state, the L3 shared cache is valid.

Package C6 State

A processor enters the package C6 low-power state when:

•At least one core is in the C6 state.

•The other cores are in a C6 or deeper power state and the processor has been granted permission by the platform.

•If the cores are requesting C7 state, but the platform is limiting to a package C6 state, the last level cache in this case can be flushed.

In package C6 state all cores have saved their architectural state and have had their core voltages reduced to zero volts. It is possible the L3 shared cache is flushed and turned off in package C6 state. If at least one core is requesting C6 state, the L3 cache will not be flushed.

Package C7 State

The processor enters the package C7 low-power state when all cores are in the C7 state. In package C7, the processor will take action to remove power from portions of the system agent.

Core break events are handled the same way as in package C3 or C6 state.

Note: C7 state may not be available on all SKUs.

The Intel CM8063701159502, or BX80637I53470, is a powerful CPU designed for modern computing needs. This processor belongs to Intel's 4th generation of Core i5 processors, commonly known as "Haswell". It showcases Intel's commitment to enhancing performance, increasing energy efficiency, and delivering an enriching user experience.

One of the main features of the Intel Core i5-3470 is its quad-core architecture. This allows the processor to handle multiple threads simultaneously, making it adept at multitasking and running demanding applications efficiently. With a base clock speed of 3.2 GHz, it can boost up to 3.6 GHz using Intel’s Turbo Boost technology, providing additional power when needed for intensive tasks like gaming or video editing.

The Intel i5-3470 features Intel's HD Graphics 2500, which offers decent graphics performance for everyday tasks and casual gaming. This integrated graphics solution is capable of delivering high-definition visuals and supports DirectX 11, making it suitable for lightweight gaming experiences without the need for an additional dedicated graphics card.

Another standout characteristic of the BX80637I53470 is its support for Intel Smart Cache, which is an advanced caching technology. It provides a shared cache pool that enhances performance by reducing the time it takes to access frequently used data. This feature, coupled with Intel's instruction set architecture, allows for improved processing agility and efficiency across applications.

The processor is built on a 22nm manufacturing process, which results in reduced power consumption and heat generation compared to its predecessors. It has a thermal design power (TDP) of 77 watts, making it energy efficient while still delivering robust performance. Additionally, the Core i5-3470 supports DDR3 memory, with speeds up to 1600 MHz, enabling quick data retrieval and improved system responsiveness.

Security is another important aspect of the Intel i5-3470, featuring Intel Secure Key and Intel AES New Instructions (AES-NI), which protect sensitive data and enhance encryption performance.

In conclusion, the Intel CM8063701159502, or BX80637I53470, encapsulates modern computing technology with its powerful quad-core performance, integrated graphics, energy efficiency, and robust security features, making it a versatile choice for a wide range of computing tasks. Whether users are engaging in casual gaming, productivity tasks, or multimedia consumption, this processor demonstrates a solid balance of performance and efficiency, providing an excellent computing experience overall.
