6月27日,Intel公司基于酷睿微体系架构设计的第一款处理器产品——Intel至强5100在北京正式发布。研发代码为Woodcrest的Intel至强5100主要面向服务器、工作站、通信、存储和嵌入式细分市场。酷睿微体系架构是Intel新一代的Core架构。Intel下一代桌面核心、移动核心和服务器核心都将采用这一统一架构。Intel酷睿微体系架构的设计目标就是提高处理器每瓦特性能。通过宽动态指令执行、高级数字媒体增强、智能缓存加速、智能电源管理、智能缓存等技术的使用,Intel进一步优化了多核处理器的能效。与上一代Intel服务器产品相比,双核Intel至强处理器5100系列实现了135%的性能提升和40%的能耗节省。Woodcrest被Intel认为是挑战AMD Opteron处理器最佳的产品,因为其全新设计的架构会拥有非常高的单位执行效率。相比于原来的至强2.80GHz,新架构的Woodcrest的性能将增加80%,功耗则减少35%。Intel将出货的5100系列产品,CPU主频达3.0GHz,总线频率升级到1333MHz,双核共事4MB的L2高速缓存。在3GHz版本的产品中,其中一款的热设计功耗(TDP)为80瓦,其他款的热设计功耗是65瓦。此外还将在第三季度出厂一款主频在2.33GHz、热设计功耗仅为40瓦的低电压产品。点评：在Intel发布至强5100之前,Intel还发布了采用老一代架构的至强5000处理器(研发代号为Dempsey)。Dempsey满足追求性价比的低端用户的需求,Woodcrest主要面向中高端至强用户。而到明年四路至强处理器发布后,双核至强将逐渐走向低端。至此,我们看到了一个完整的双核至强产品线。而由于同样基于Bensley平台,至强用户将获得包括全缓冲内存(FB-DIMM)、Intel虚拟化技术(VT)、Intel主动服务器管理(Intel Active Server Manager)技术和IntelI/O加速技术(I/OAT)等方面的支持。
June 27, Intel’s first micro-system architecture based on Core micro-processor design - Intel 5100 officially released in Beijing. The Intel Xeon 5100 code-named Woodcrest is targeted at servers, workstations, communications, storage and embedded segments. Core microarchitecture is Intel’s new generation of Core architecture. Intel next-generation desktop core, mobile core and server core will adopt this unified architecture. The design goal of the Intel Core microarchitecture is to increase processor performance per watt. Intel further optimizes the energy efficiency of multi-core processors through the use of technologies such as wide dynamic instruction execution, advanced digital media enhancements, intelligent cache acceleration, intelligent power management, and smart caching. Compared with the previous generation Intel server products, the dual-core Intel Xeon processor 5100 series achieved 135% performance improvement and 40% energy saving. Woodcrest is considered by Intel to be the best AMD AMD Opteron processor product because of its newly designed architecture with very high unit execution efficiency. Compared to the original Xeon 2.80GHz, the new architecture of Woodcrest will increase performance by 80% and power consumption by 35%. Intel will ship 5100 series products, CPU clocked at 3.0GHz, the bus frequency is upgraded to 1333MHz, dual-core work 4MB of L2 cache. In the 3GHz version, one of the thermal design power (TDP) of 80 watts, other models of thermal design power is 65 watts. In addition, it will be manufactured in the third quarter of a frequency of 2.33GHz, thermal design power is only 40 watts of low-voltage products. Comments: Before Intel released the Xeon 5100, Intel also released the Xeon 5000 processor with the older generation architecture (code-named Dempsey). Dempsey to meet the pursuit of cost-effective low-end users demand, Woodcrest mainly for high-end Xeon users. Xeon quadruple processor and next year after the release of dual-core Xeon will gradually move to the low end. So far, we have seen a complete dual-core Xeon product line. And thanks to the same Bensley platform, Xeon customers will gain access to a full range of software including FB-DIMMs, Intel Virtualization Technology (VT), Intel Active Server Manager and Intel I / O Acceleration Technology (I / OAT) and other support.
