Chinese Name: Xeon mbth: Xeon Class: Intel Processor Development Code: Woodcrest Mobile Development Code: Merom Positioning: Server/Workstation Recommended CPU :E3 123 1 V3 0v3 and E3 1230 V3 R&D Background, the first generation processor, performance improvement, Xeon processor, single-core processor, and so on. Xeon is a server of Intel. Intel processors have basically formed the following pattern: server Xeon, high-end Core i9/i7, mid-range Core i5/ Core i3/ Pentium and low-end Celeron. Among them, Xeon can use multiprocessor technology. Xeon Xeon CPU old picture first generation processor 1998 Intel released Pentium II Xeon processor. Xeon is a new brand launched by Intel. At that time, in order to distinguish the server market from the ordinary PC market, Intel decided to develop a brand-new server CPU, named Pentium II Xeon, which was obviously different from the ordinary CPU, to replace the Pentium Pro brand used before. This product line is aimed at the high-end enterprise server and workstation market; This is an important step for Intel to further differentiate the market. Xeon is mainly used for running commercial software, Internet service, company data storage, data classification, database, electronic and mechanical automation design, etc. Xeon Quad-Core Processor Template Pentium II Xeon processor is not only faster, but also has larger cache. More importantly, it can support 4 or 8 SMP symmetric multi-CPU processing functions at most. It uses the Slot 2 interface which is different from the Pentium Ⅱ Slot1interface, and can only be used in conjunction with the dedicated server motherboard. Performance improvement 1999, Intel released Pentium Ⅲ Xeon processor. I believe that everyone still remembers what the Pentium 3 processor with the "Copper Mine" core was like in those years, and it is also known as a classic product. As the successor of Pentium II Xeon, it not only adopted a brand-new design on the core architecture, but also inherited 70 instruction sets added by Pentium III processor to better execute multimedia and streaming media applications. In addition to facing the enterprise market, Pentium III Xeon has also strengthened its e-commerce application and advanced business computing capabilities. Intel also divided Xeon into two parts, low-end Xeon and high-end Xeon. The low-end Xeon, like ordinary Coppermine, is only equipped with 256KB L2 cache and does not support multiprocessors. In this way, the performance gap between the low-end Xeon and the ordinary Pentium III is very small, and the price is similar; High-end Xeon processors still have the previous features, supporting larger caches and multiple processors. Xeon processor 200 1 Intel releases Xeon processor. Intel's removal of the name Pentium from Xeon does not mean leaving x86, but making the brand concept clearer. The market positioning of Xeon processor is also more aimed at high performance, load balancing, multi-channel symmetric processing and other characteristics, which are not available in Pentium brand desktop computers. Xeon processor is actually based on Pentium 4 kernel, and also has 64-bit data bandwidth. However, due to adopting the same principle as AGP 4X-"quadruple speed" technology, its front-end bus has been greatly improved, and its performance is far better than Pentium III Xeon processor. Xeon processor is based on Intel's NetBurst architecture, which has more advanced network functions and more complex 3D graphics performance. On the other hand, the chipset supporting Xeon also better supports server-side computing in parallel computing, supports high-performance I/O subsystems (such as SCSI disk array and gigabit network interface), and supports PCI bus segmentation. Prestonia Prestonia, a single-core processor, is the second generation core of Xeon processor. The primary difference between Prestonia and the first generation Foster core is the difference in the integrated secondary cache capacity, the former is 5 12KB, while the latter is only 256KB. Prestonia core processor also adopts the advanced manufacturing technology of 0. 13 micron. But the biggest advantage of Prestonia's kernel is that it supports hyper-threading. Hyper-threading, previously known as Jackson technology, is an extension of SMT multithreading technology. Its main function is to make the processor work in multithreading mode (each processor can handle multiple processes at the same time). Xeon Prestonia Noona This is Intel's Xeon CPU core, which adopts 90nm process, uses 800Mhz FSB, and has 16KB L 1 cache, 1MB L2 cache and 12KB uOps Trace cache, and supports SSE3 and hyper-threading. The corresponding Xeon processor supports both 32-bit and 64-bit computing through EM64T technology, and realizes enhanced SpeedStep technology through integrating DBS(Demand Based Switching), which can dynamically adjust the working frequency and power consumption of the processor according to the workload. The core products of Xeon Nocona Irwindale, such as front-end bus, hyper-threading Ⅱ Ⅱ, enhanced Speedstep, EDB, EM64T, etc., are completely consistent with Noona. The biggest difference between this core and Nocona core is that the secondary cache is further upgraded to 2MB, and the frequency jumps from 3.0G, which is somewhat similar to the architecture of Pentium 4 600 series processors. However, due to the increase of secondary cache, the process has not been improved, which leads to the power and calorific value of this processor are much higher than that of Nocona, so we should pay enough attention to the heat dissipation problem when purchasing this processor. The new core of Conroe Intel Xeon 3000 series uses the same LGA 775 pin as the Intel Core 2 dual core, instead of the LGA 77 1 pin used by Woodcrest. Xeon 3000 series processors run on 1066 MHz system bus (FSB), contain 4 MB or 2 MB shared L2 cache, and support Intel 64-bit extension technology (Intel EM64T). Intel virtualization technology and enhanced Intel SpeedStep technology, including Xeon 3040, 3050, 3060 and 3070, as well as Intel Xeon 3070 (2.66 GHz/4 MBL2/FSB1066) and Intel Xeon 3060 (2.40 GHz/4 MB L2/FSB10). Intel Xeon 3050 (2.13ghz/2MB L2/FSB100) of which 3040 and 3050 are equipped with 2mbl2 cache, and 3060 and 3070 are equipped with 4MB L2 cache. The new Xeon processor uses Core, which has greatly improved the performance and power consumption compared with the previous generation NetBurst. Xeon Conroe dual-core processor Dempsey Dempsey is a dual-core version of Xeon, and the model is named 50xx dual-core processor. Including 5030(2x2MB/2.67GHz/667 MHz front-end bus/power 95W/DP), 5050(2x2MB/3.00GHz/667MHz front-end bus/power 95W/DP), 5060 (2x2MB/3.20GHz/ front-end bus 1066 MHz/ dp). 5063(2x2MB/3.20GHz/ front bus 1066 MHz/ power 95W/DP), (5080 x2 MB/3.73 GHz/ front bus 1066 MHz/ power 130W/DP).

These processors are equipped with 4MB L2 cache, each core has 2MB L2 cache, and its front-end bus is 1066MHz or 667MHz, which can provide 8.5GB/s or 5.3GB/s transmission bandwidth. Dual-core Xeon Dempsey with 65nm technology adopts LGA77 1 interface. Chipsets matching this 50XX series are INTEL 5000X, 5000P, 5000Z and 5000V. Xeon Dempsey WoodCrest This is Xeon's server-class dual-core processor with Core microarchitecture. WoodCrest core processors include Qiangqiang 5110 (1.6ghz/4mbl2/1066mhz FSB) and Qiangqiang 5120 (1.86ghz/4mbl2).

Xeon WoodCrest CPU performance With the birth of Intel Core Extreme Edition QX9650, the processor began to enter the 45NM period. This processor is a Xeon quad-core processor with powerful performance and ultra-low calorific value. Make the position of Intel chip giant more stable. Intel Xeon processor 7000 series has added three 6-core processors: X7460, L7455 and E7450 processor numbers, δ L2 cache L3 cache clock speed (main frequency), front-side bus system type, power core number, x7460 9mb 1 6mb2.66ghz1066mhz multiplex1 30W6L74559mb12mb2ghz1066mhz multi-channel 656E74509mb12mb2.40ghz1066mhz multi-channel 90W 6 Xeon series The existing Xeon series is divided into three series like Core, and there is also an accelerator card Xeon Phi. Only some Xeon E3 provide built-in drawing cores, while others do not have iGPU. The first digit of the four-bit model represents the maximum number of processors, including unidirectional, bidirectional, four-way and eight-way processors. The second number represents the type of CPU socket, which has four specifications. The first generation products 1, 2, 4, 6 and 8 represent BGA 1284, LGA 1 155, LGA 1356 and LGA 20 165438+ respectively. Xeon E3 Xeon E3 is a single processor family for workstations and entry-level servers. It has two sub-series E3- 1 100 and E3- 1200. Except E3- 1220L is dual-core, others are quad-core, but there are four-thread and eight-thread models. Xeon E3 has the fastest update speed, and it is updated with consumer-grade Core i7 every year. Sockets are the same as consumer products, using LGA 1 155 and LGA 1 150. The model of the first/second/third generation products is E3- 1200/E3-65438+. E3 123 1 v3 and E3 1230 v3 are very cost-effective. Xeon E5 Xeon E5 is a processor family for high-end workstations and servers. This series is updated every year, but its architecture lags behind Xeon E3. 20 13 in the third quarter, Xeon E5 was updated to Ivy Bridge microarchitecture. At the same time, Xeon E3 was updated to Haswell microarchitecture. Xeon E5 has five sub-series: entry-level single processor series E5- 1400, high-end single processor series E5- 1600, entry-level dual processor series E5-2400 and mainstream dual processor series E5-2600 and E5-4600. The first two are LGA 1600. Xeon E7 Xeon E7 is a processor family for mission-critical and data centers, emphasizing reliability, availability and maintainability (RAS). The first generation of Xeon E7 was launched in the second quarter of 201/kloc-0, providing three sub-series, namely the top eight-socket, four-socket and two-socket processor series E7-8800, E7-4800 and E7-2800, which can support up to 4TB, 2TB and 1TB of memory. The whole line is code-named Westmere-EX, which supports four-channel memory technology and adopts LGA 1567, which is also a series using this socket. The second generation of Xeon E7 was launched in 20 14 1 quarter, with the code name Ivy Bridge-EX. It provides three sub-series E7-8800/4800/2800v2. All models support the maximum memory 1.5TB, and LGA 20 1 1 is adopted at most. It adopts 8-way Xeon E7, and supports up to 12TB memory. Although the name is the same, this LGA 20 1 1 is dedicated to Xeon E7, but it is not compatible with Xeon E5 or Core i7. Xeon Phi Xeon Phi is a brand of computing accelerator card. It uses many integrated cores, with a maximum of 6 1 core. With the help of hardware-based hyper-threading technology, each core has 4 threads, a total of 244 threads. However, this hyperthreading cannot be turned off. Xeon Phi is used for high-efficiency computing (HPC) acceleration, mainly for supercomputers and HPC servers. The emergence of Xeon Phi is to counter the popularization of GPGPU in HPC field. The main computing power of Titan (20121-2013June, the fastest supercomputer in the world) in Oak Ridge National Laboratory comes from NVIDIA TeslaGPGPU instead of CPU. The first batch of Xeon phi core is code-named Knights Corner, excluding customized products. There are six models, 3100/5100/7100, which are 57/60/6 1 core and 6GB/8GB/ 100 respectively. The difference between the two models lies in the radiator, including active type, passive type and no radiator. The active type (a) refers to the fan, while the passive type (p) only has a large radiator, and no radiator (x) needs water cooling. Xeon E7v2 model classification is based on the new architecture of Sandy Bridge, and Xeon E3- 1200 series processors can be roughly divided into three parts. 1.
