New processor features

• 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 is a technology that activates the work of individual nodes of the chip as needed for the execution of tasks, which significantly reduces the power consumption of the system as a whole
• Intel Advanced Smart Cache is a technology that uses a shared L2 cache for all cores, which reduces overall power consumption and improves performance, while, as needed, one of the processor cores can use the entire amount of cache memory during dynamic disabling another core
• Intel Smart Memory Access Memory optimization technology that reduces response time and increases memory bandwidth
• Intel Advanced Digital Media Boost — A single clock processing technology for 128-bit SSE, SSE2 and SSE3 instructions widely used in multimedia and graphics applications
• Processors Core 2 Duo and Core 2 Extreme also support EM64T technology.

by release of the processors of the family Core Corporation Intel intends to return the leading position in the confrontation with AMD , which it occupied after the production of the processors family Pentium 4.
