What processor is intel xeon

Intel Xeon is Intel's Xeon processor, a microprocessor produced by Intel that is used in "mid-range" enterprise servers and workstations. Xeon is based on the Pentium microprocessor P6 architecture, which is designed to work with the new Fast Peripheral Component Interconnect and accelerated graphics ports; computers equipped with Xeon microprocessors generally use Windows NT, NetWare or Unix operating systems.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

intel xeon is Intel’s Xeon processor.

Xeon is a microprocessor produced by Intel that is used in "mid-range" enterprise servers and workstations. On Intel's server motherboards, up to eight Xeon processors can share the 100MHz bus for multi-processing. Xeon is designed for use on the Internet and a large number of data processing services, such as engineering, imaging and multimedia applications that require the rapid transfer of large amounts of data.

Based on the Pentium P6 microprocessor architecture, it is designed to work with the new Fast Peripheral Component Interconnect and the Accelerated Graphics Port. Xeon has: 512 kilobytes or 1 megabyte, 400MHz cache memory, a high-speed bus to transfer data between the processor, RAM and I/O devices, and an extended server memory structure that can provide 36-bit addresses.

Computers equipped with Xeon microprocessors can generally use Windows NT, NetWare or Unix operating systems, and their systems are comparable to Sun Microsystem, Silicon Graphics, etc.

In 2001, Intel released the Xeon processor. Intel removed the Pentium name from the front of Xeon. This does not mean that it is divorced from x86, but it makes the brand concept clearer. The market positioning of Xeon processors is also more focused on features such as high performance, balanced load, and multi-channel symmetric processing, which the Pentium brand of desktop computers does not have. The Xeon processor is actually based on the Pentium 4 core and also has 64-bit data bandwidth. However, because it uses the same principle as AGP 4X - "quad speed" technology, its front-side bus has been greatly improved. The performance is far better than the Pentium III Xeon processor. Xeon processors are based on Intel's NetBurst architecture and have more advanced network functions and more complex 3D graphics performance. On the other hand, Xeon-enabled chipsets also support parallel computing and high-performance I/O subsystems (such as SCSI disk array, Gigabit network interface), support PCI bus segmentation, etc. to better support server-side computing.

Single-core processor

• Prestonia

  Prestonia is the second-generation core of the Xeon processor. The primary difference between Prestonia and the first-generation Foster core is the difference in integrated second-level cache capacity. The former is 512KB, while the latter is only 256KB. The Prestonia core processor also uses an advanced 0.13 micron manufacturing process. But the biggest advantage of the Prestonia core is the added support for Hyper-Threading. Hyperthreading was previously called Jackson technology. This is an extension of multi-threading (SMT Simultaneous Multi-Threading) technology. Its main function is to allow the processor to perform multi-threaded work in single-processor working mode (each processor can simultaneously Processing of more than one process).

• Nocona

  This is Intel's XEON CPU core, using 90nm process, using 800Mhz FSB, with 16KB L1 cache, 1MB L2 cache and 12KB uOps Trace cache, supporting both SSE3 and HyperThreading. The corresponding Xeon processor supports both 32-bit and 64-bit computing through EM64T technology, and implements enhanced SpeedStep technology through integrated DBS (Demand Based Switching, based on demand switching technology), which can dynamically adjust the processor operating frequency and power consumption according to the workload.

• Irwindale

  The core of Xeon products, front-side bus, HyperThreadingⅡ, enhanced Speedstep, EDB and EM64T are completely consistent with Nocona. The biggest difference between this core and the Nocona core is that the second-level cache is further increased to 2MB, and the frequency starts from 3.0G, which is somewhat similar to the architecture of the Pentium 4 600 series processor. However, due to the increase in the level 2 cache, the process has not been improved. As a result, the power and heat generation of this processor are much higher than that of Nocona. When purchasing this processor, you should pay enough attention to heat dissipation.

• Conroe

  The new core of the Intel Xeon 3000 series uses the same LGA 775 pin as the Intel Core 2 Duo, instead of the LGA 771 pin used by Woodcrest. Xeon 3000 series processors run on the 1066 MHz system bus (FSB), contain 4 MB or 2 MB shared L2 cache, and support Intel 64-bit extended technology (Intel EM64T), Intel Virtualization Technology (Intel Virtualization Technology) and Enhanced Intel SpeedStep technology, including Xeon 3040, 3050, 3060 and 3070, Intel Xeon 3070 (2.66 GHz/4MB L2/FSB1066), Intel Xeon 3060 (2.40 GHz/4MB L2/FSB1066), Intel Xeon 3050 (2.13 GHz/2MB L2 /FSB1066), Intel Xeon 3040 (1.83 GHz/2MB L2/FSB1066). The 3040 and 3050 are equipped with 2MB L2 cache, while the 3060 and 3070 are equipped with 4MB L2 cache. The new Xeon processor uses the Core core, which has greatly improved performance and power consumption compared with the previous generation NetBurst.

Dual-core processor

Improved, supports Intel EM64T, Intel Execute Disable Bit, Intel Virtualization Technology functions, while the Demand-Based Switching function is only available for Xeon 5140 or above models. There is also a low-power product, XEON 5148 LV, with a frequency of 2.33GHz/4MB L2 Cache/1333MHz FSB, but the maximum power consumption is only 40W, which is half of the normal model, and fully supports Intel EM64T, Intel Execute Disable Bit, and Intel Virtualization Technology function and Demand-Based Switching function. The chipsets used with this 51XX series are INTEL 5000X, 5000P, 5000Z, and 5000V.

• Xeon Phi

  Hardware-based hyper-threading allows each core to have 4 threads, for a total of 244 threads, but this hyper-threading cannot be turned off. Xeon Phi is used for high-efficiency computing (HPC) acceleration, mainly used in supercomputers and HPC servers. The emergence of Xeon Phi is to compete with the popularity of GPGPU (general-purpose GPU) in the HPC field. The main computing power of the supercomputer Titan (the world's fastest supercomputer from November 2012 to June 2013) at the Oak Ridge National Laboratory in the United States is not Not from the CPU, but from the NVIDIA TeslaGPGPU.

  The first batch of Xeon Phi codenames are all Knights Corner, excluding customized products. There are six models in total. 3100/5100/7100 each have two models, with 57/60/61 cores and 6GB respectively. /8GB/16GB memory. The difference between the two models is the difference in radiators, including active, passive and no radiator. Active (A) means there is a fan, while passive (P) only has a large heat sink, and no radiator (X) is required. Use with water cooling.
