64-bit Intel® Xeon™ Processor MP with up to 8MB L3 Cache DatasheetThe 64-bit Intel® Xeon® processor MP with up to 8MB L3 cache is a 64-bit multi-processor capable server processor based on improvements to the Intel NetBurst® microarchitecture. It maintains the tradition of compatibility with IA-32 software and includes features found in the Intel Xeon processor such as Hyper Pipelined Technology, a Rapid Execution Engine, and an Execution Trace Cache. Hyper Pipelined Technology includes a multi-stage pipeline, allowing the processor to reach much higher core frequencies. The 667 MHz front side bus is a quad-pumped bus running off a 166 MHz system clock making 5.3 GB per second data transfer rates possible. The Execution Trace Cache is a level 1 (L1) cache that stores decoded micro-operations, which removes the decoder from the main execution path, thereby increasing performance. In addition, the 64-bit Intel Xeon processor MP with up to 8MB L3 cache includes the Intel® Extended Memory 64 Technology, providing additional address capability.In addition, enhanced thermal and power management capabilities are implemented, including Thermal Monitor, Thermal Monitor 2 (TM2), and Enhanced Intel SpeedStep® Technology. Thermal Monitor and Thermal Monitor 2 provide efficient and effective cooling in high temperature situations. Enhanced Intel SpeedStep Technology allows trade-offs to be made between performance and power consumption. This may lower average power consumption (in conjunction with OS support).The 64-bit Intel Xeon processor MP with up to 8MB L3 cache supports Hyper-Threading Technology. This feature allows a single, physical processor 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, control registers to provide increased system responsiveness in multitasking environments, and headroom for next generation multi-threaded applications.Read the full 64-bit Intel® Xeon™ Processor MP Datasheet.
