Introduction 1 Introduction Note: 1.1 1.1.1 The Intel® Core™ i7 processor Extreme Edition and Intel® Core™ i7 processor are intended for high performance high-end desktop, Uni-processor (UP) server, and workstation systems. The processor implements key new technologies: • Integrated Memory Controller • Point-to-point link interface based on Intel® QuickPath Interconnect (Intel® QPI). Reference to this interface may sometimes be abbreviated with Intel QPI throughout this document. In this document the Intel® Core™ i7 processor Extreme Edition and Intel® Core™ i7 processor will be referred to as "the processor." This datasheet provides register descriptions for some of the registers located on the processor. The processor is optimized for performance with the power efficiencies of a low-power microarchitecture to enable smaller, quieter systems. The Intel® Core™ i7 processor Extreme Edition and Intel® Core™ i7 processor are multi-core processors, based on 45 nm process technology. Processor features vary by component and include up to two Intel QuickPath Interconnect point to point links capable of up to 6.4 GT/s, up to 8 MB of shared cache, and an integrated memory controller. The processors support all the existing Streaming SIMD Extensions 2 (SSE2), Streaming SIMD Extensions 3 (SSE3) and Streaming SIMD Extensions 4 (SSE4). The processor supports several Advanced Technologies: Execute Disable Bit, Intel® 64 Technology, Enhanced Intel SpeedStep® Technology, Intel® Virtualization Technology (Intel® VT), Intel® Turbo Boost Technology, and Hyper-Threading Technology. Terminology A '#' symbol after a signal name refers to an active low signal, indicating a signal is in the active state when driven to a low level. For example, when RESET# is low, a reset has been requested. Processor Terminology Commonly used terms are explained here for clarification: • DDR3 - Double Data Rate 3 synchronous dynamic random access memory (SDRAM) is the name of the new DDR memory standard that is being developed as the successor to DDR2 SDRAM. • Enhanced Intel SpeedStep® Technology - Enhanced Intel SpeedStep Technology allows trade-offs to be made between performance and power consumption. • Execute Disable Bit - Execute Disable allows memory to be marked as executable or non-executable, when combined with a supporting operating system. If code attempts to run in non-executable memory the processor raises an error to the operating system. This feature can prevent some classes of viruses or worms that exploit buffer over run vulnerabilities and can thus help improve the overall security of the system.
