At Intel, our processor series numbers help differentiate processor features beyond front-side bus (FSB) speed and brand name. New advancements in our processors — other than bus speed — like number of cores, architecture, cache, power dissipation, and embedded Intel technologies, contribute significantly to performance, power efficiency, and other end-user benefits. Our processor sequences will help developers decide on the best processor for their platform designs, and help end-users understand all the characteristics that contribute to their overall experience.

Quad-Core Intel Xeon processor 5300 series delivers the most headroom and performance of any two-processor general-purpose server, so you can confidently consolidate applications onto fewer systems using proven industry-standard virtualization solutions. With the highest performance per watt of our Intel® Xeon® processors, you can virtualize environments onto dense 1U rack and blade form factors with fewer cooling challenges, giving you more performance and services per square foot.Quad-Core Intel Xeon processor 5300 series integrates virtualization hardware support with Intel Virtualization Technology, which enables more efficientvirtualization solutions and greater capabilities including 64-bit guest operating system support. Thenew Quad-Core Intel Xeon processor 5300 includesnew Intel VT extensions around interrupt handlingthat will further optimize virtualization software efficiency. 5 A growing number of independent softwarevendors (ISV) and original equipment manufacturers(OEM) support virtualization on Intel VirtualizationTechnology-enabled platforms through the Intel and VMware Virtualize ASAP program, the industry’s first and only collaborative, global effort to deliver optimized virtualization solutions and practices to IT professionals and companies. The 64-bit computing of the Quad-Core Intel Xeon processor 5300 series gives you additional application headroom, memory flexibility, and increased security for virtual and dedicated environments. By supporting larger data sets and both 32- and 64-bit applications,Dual-Core and Quad-Core Intel Xeon processor-based servers and workstations allow the smooth migrationof your business to 64-bit applications. And, withmillions of 64-bit processors already shipped, youknow you can depend on Intel’s proven track recordto help you make a smooth transition to the nextlevel of computing.

With 4 cores, large 8 MB of on-die L2 cache,2 and the performance-enhancing and energyefficient technologies of the Intel Core microarchitecture, the Quad-Core Intel Xeon processor 5300 series helps IT departments maximize performance and density with fewer cooling challenges. Many server applications are wellthreaded as a result of years of running in symmetric multi-processing environments.Well-threaded server applications will benefit from more cores, larger cache, and higher throughput and memory apacity of Quad-Core Intel Xeon processor 5300 series-based servers and the Intel Core microarchitecture.

Two-processor platforms based on the Quad-Core Intel® Xeon® processor 53001 series and the Intel® Core™ microarchitecture help companies maximize data center performance and density, while reducing cooling challenges. Platforms based on Intel’s new quad-core technology make it easier to deliver more business services in existing facilities, or condense applications for more efficient operations at lower total cost of ownership (TCO).Two-processor platforms based on the Quad-Core Intel Xeon processor 5300 series deliver 8-thread, 32- and 64-bit processing capabilities with 8 MB of L2cache per processor,2 providing more computing for threaded applications in a variety of deployments. The Quad-Core Intel Xeon processor 5300 series is ideal for the densest of computing environments where best performance and performance per watt are key requirements. Supported by the Intel® 5000 chipset family and Fully Buffered DIMM (FBDIMM) technology, Quad-Core Intel Xeon processor 5300 series-based platforms are expected to deliver breakthroughperformance with better power efficiency, delivering up to 1.5 times the performance compared to leading Dual-Core Intel® Xeon® processor 5100 series in the same power envelope and up to 2.4 times the performancecompared to the best published results of AMD Opteron* Model 2222.3
