Latest Processor


The 45nm Hi-k Intel Xeon processors are compatible with server platforms using the Intel 5000 chipset family. In addition, Intel is launching three platform solutions to support 45nm processors, including here the Intel 5400 chipset-based platform (previously codenamed "Stoakley") that is optimized for high-bandwidth applications such as high-performance computing (HPC), the Intel 5100 Memory Controller Hub chipset and Intel ICH-9R I/O controller (previously codenamed "Cranberry Lake"), which are cost-optimized solutions that support either one or two processors and also provide reduced power consumption using native DDR2 memory, as well as the Intel 3200 chipset-based platform (previously codenamed "Garlow") that is specifically designed for single-processor entry servers. Furthermore, Intel’s 45nm Hi-k Xeon processors also extend performance-per-watt characteristics by delivering an improvement of 38 percent over its previous-generation Quad-Core Xeon 5300 Series processors.The move from 65nm to 45nm involves more than just a shrink of current chip designs. The processors also include such additional features as new Intel Streaming SIMD Extensions 4 (SSE4), which are 47 new instructions that speed up workloads including video encoding for high-definition and photo manipulation, as well as key HPC and enterprise applications. Furthermore, they come packed with enhanced Intel Virtualization Technology, as the virtual machine transition (entry/exit) times are improved by an average of 25 to 75 percent through hardware with no changes to software required.Other additional features include a fast divider that roughly doubles the speed over previous generations for computations used in nearly all applications through a technique called Radix 16, a wider 128-bit shuffle unit that improves the performance for SSE-related instructions that have shuffle-like operations. This feature will increase performance for content creation, imaging, video and high-performance computing
