Notes

Core 2 Duo is a family of 64-bit client microprocessors based on the Core microarchitecture, designed and manufactured by the Intel Corporation.

1. Features of the new

processors

• Intel Wide Dynamic Execution is a technology that executes more instructions per clock cycle to improve application execution efficiency and reduce power consumption. Each processor core can execute up to four instructions simultaneously using a 14-stage pipeline
• Intel Intelligent Power Capability — a technology that activates the work of individual nodes of the chip for the execution of tasks as needed, which significantly reduces the power consumption of the system as a whole
• Intel Advanced Smart Cache is a shared L2 cache technology that reduces overall power consumption and improves performance by allowing one of the processor cores to use the entire amount of cache memory when needed dynamically. disabling another core
• Intel Smart Memory Access Memory optimization technology that reduces response time and increases memory bandwidth
• Intel Advanced Digital Media Boost — A technology that processes 128-bit SSE, SSE2, and SSE3 instructions widely used in multimedia and graphics applications in a single clock cycle
• Processors Core 2 Duo and Core 2 Extreme also supports EM64T technology.

With the release of the Core processor family, the Intel corporation intends to regain the leading position in the confrontation with the AMD , which it held after the release of the Pentium 4 processor family.
