Among the CPUs currently produced by Intel, Pentium 4 and celon are PC oriented, while Xeon, xeonmp, and itanium are for workstations and servers. Among them, itanium is a 64-bit CPU that is completely different from other CPUs. It is not designed for use in existing Windows applications. Although other processors differ in the highest operating frequency, FSB (Front-End bus frequency), and cache capacity, the internal design is basically the same, wh
The Chinese IT lab reported on August 1 that today, I learned that this new server product PowerEdgeT300 for small and medium-sized enterprise customers is now available at a price reduction promotion, not only equipped with a 45 nm Xeon 3000 series processor, this allows small and medium-sized enterprises to obtain more value-added server performance and reliability. At the same time, they can deliver 1 4G Ultra-High Disk of Kingston (yi disk) at a p
processor has two architecture states on a single core, which makes the physical processor look like two logical processors are providing services for the thread. The system BIOS lists the status of each architecture in a physical processor. Because operating systems that support hyper-threading use a logical processor, these operating systems have twice the resources available to provide services for threads.

PS: These six years for the world of CPU, the transformation is too fast, "rapid change" seems to be not enough to describe the changes in the CPU over the years.
The Intel Pentium 4 processor family is based on the Intel NetBurst microarchitecture. The Pentium 4 processor introduced SSME2 (streaming SIMD

The DV2 series of Vm,cpu,ram and local temporary SSD disk space is the same as the D series. As follows: The DV2 series of VMS, compared to the D-series, is mainly on the CPU.The DV2 series of CPUs, the model is the Intel Xeon e5-2673 V3 (Haswell architecture ), t
transistors and know that the Opteron 6276 is a bit larger than Xeon, and is it fair to compare their performance? If you have a stack of hardware, you should be able to cope with more load, which Opteron still has an advantage, because it can handle 16 threads at the same time, and Xeon can only handle 12.But if we look at the actual running results, we know that the opposite is true, AMD needs twice time

The "Physical ID" and "core ID" of multiple logical CPUs are the same, indicating that hyper-threading is turned on.2. There is an LM tag in the flags stating that it is a 64-bit CPU3, my processor has 4 different numbers, and belong to a physical ID, while the CPU cores val

Through decades of technology accumulation, x86 server in the field of server status is almost alone and defeated. The small and flexible x86 server is widely used in the market, and it can be used in many fields such as file, print, communication, web, email, database and application services in the Internet and LAN.
The biggest feature of the x86 server is that it can be compatible with Windows operating systems, all with Intel's CPU. and Intel's x86

Small knitting personally think the best CPU should be the Intel Xeon e7-8870.
The key parameters for the Intel Xeon e7-8870 are as follows:
Number of cores: 10
Number of Threads: 20
Bus frequency: 6400
L3 Cache: 30MB
Production process: 32 NM
Working power: 130W
CPU Architecture: 64-bit
Instruction set: sse4.1,4.2
Virtualization Technology: Intel VT
The basic parameters of the Intel
processor executes the current instruction, which always causes an explicit bus lock to appear (2) in Pentium4, Inter Xeon, and P6 series processors, the lock operation is handled by either a cache lock or a bus lock. If memory access is cached and affects only a single cache row, the cache lock is invoked in the operation, and the actual area in the system bus and system memory is not locked. At the same time, other Pentium4, Intel
