Lenovo 44E4517 Processor Computer Component

The Intel® Xeon® Processor 7400 Series is a four or six core product for multiprocessor servers. The processor is a single die based on Intel’s 45 nanometer process technology combining high performance with the power efficiencies of a low-power microarchitecture. The processor maintains the tradition of compatibility with IA-32 software. Some key features include on-die, 32 KB Level 1 instruction data cache per core and 3 MB of shared Level 2 cache per two processor cores with Advanced Transfer Cache Architecture. The Intel® Xeon® Processor 7400 Series will be available with 12 MB or 16 MB of on-die level 3 (L3) cache. The processor’s Data Prefetch Logic speculatively fetches data to the L2 cache before an L1 cache requests occurs, resulting in reduced bus cycle penalties and improved performance. The 1066 MTS Front Side Bus (FSB) is a quad-pumped bus running off a 266 MHz system clock making 8.5 GBytes per second data transfer rates possible.
Enhanced thermal and power management capabilities are implemented including Intel® Thermal Monitor (TM1), Intel® Thermal Monitor 2 (TM2) and Enhanced Intel SpeedStep® Technology. TM1 and TM2 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).
Processor features include Advanced Dynamic Execution, enhanced floating point and multi-media units, Streaming SIMD Extensions 2 (SSE2), Streaming SIMD Extensions 3 (SSE3) and Streaming SIMD Extensions 4 (SSE4). SSE4 extends the Intel® 64 instruction set to accelerate applications that involve graphics, video, 3D imaging, and Web services. Advanced Dynamic Execution improves speculative execution and branch prediction internal to the processor. The floating point and multi-media units include 128-bit wide registers and a separate register for data movement. SSE3 instructions provide highly efficient double-precision floating point, SIMD integer, and memory management operations.
The Intel® Xeon® Processor 7400 Series supports Intel® 64 as an enhancement to Intel's IA-32 architecture. This enhancement allows the processor to execute operating systems and applications written to take advantage of the 64-bit extension technology. Further details on Intel 64 and its programming model can be found in the Intel® 64 and IA-32 Intel® Architectures Software Developer's Manual.
