Processor—Technologies

Another aspect of the trust decision is the ability of the platform to resist attempts to change the controlling environment. The Intel TXT platform will resist attempts by software processes to change the controlling environment or bypass the bounds set by the controlling environment.

Intel TXT is a set of extensions designed to provide a measured and controlled launch of system software that will then establish a protected environment for itself and any additional software that it may execute.

These extensions enhance two areas:

•The launching of the Measured Launched Environment (MLE).

•The protection of the MLE from potential corruption.

The enhanced platform provides these launch and control interfaces using Safer Mode Extensions (SMX).

The SMX interface includes the following functions:

•Measured/Verified launch of the MLE.

•Mechanisms to ensure the above measurement is protected and stored in a secure location.

•Protection mechanisms that allow the MLE to control attempts to modify itself.

The processor also offers additional enhancements to System Management Mode (SMM) architecture for enhanced security and performance. The processor provides new MSRs to:

•Enable a second SMM range

•Enable SMM code execution range checking

•Select whether SMM Save State is to be written to legacy SMRAM or to MSRs

•Determine if a thread is going to be delayed entering SMM

•Determine if a thread is blocked from entering SMM

•Targeted SMI, enable/disable threads from responding to SMIs both VLWs and IPI

For the above features, BIOS must test the associated capability bit before attempting to access any of the above registers.

For more information, refer to the Intel® Trusted Execution Technology Measured Launched Environment Programming Guide.

3.3Intel® Hyper-Threading Technology (Intel® HT Technology)

The processor supports Intel Hyper-Threading Technology (Intel HT Technology) that allows an execution core to function as two logical processors. While some execution resources, such as caches, execution units, and buses are shared, each logical processor has its own architectural state with its own set of general-purpose registers and control registers. This feature must be enabled using the BIOS and requires operating system support.

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.
