Intel Xeon E5-2643 v4

El número de procesador Intel es sólo uno de varios factores (junto con la marca del procesador, las configuraciones del sistema y los puntos de referencia a nivel del sistema) que se deben considerar al elegir el procesador adecuado para sus necesidades informáticas.

Núcleos es un término de hardware que describe la cantidad de unidades centrales de procesamiento independientes en un solo componente informático (matriz o chip).

Cuando corresponda, la tecnología Intel® Hyper-Threading solo está disponible en núcleos de rendimiento.

Max Turbo Frequency es la frecuencia máxima de un solo núcleo a la que el procesador es capaz de funcionar utilizando la tecnología Intel® Turbo Boost y, si está presente, la tecnología Intel® Turbo Boost Max 3.0 e Intel® Thermal Velocity Boost. La frecuencia normalmente se mide en gigahercios (GHz), o mil millones de ciclos por segundo.

Intel® Turbo Boost Technology dynamically increases the processor's frequency as needed by taking advantage of thermal and power headroom to give you a burst of speed when you need it, and increased energy efficiency when you don’t.

Intel® Hyper-Threading Technology (Intel® HT Technology) delivers two processing threads per physical core. Highly threaded applications can get more work done in parallel, completing tasks sooner.

El zócalo es el componente que proporciona las conexiones mecánicas y eléctricas entre el procesador y la placa base.

CPU Cache is an area of fast memory located on the processor. Intel® Smart Cache refers to the architecture that allows all cores to dynamically share access to the last level cache.

La litografía se refiere a la tecnología de semiconductores utilizada para fabricar un circuito integrado y se expresa en nanómetros (nm), lo que indica el tamaño de las características construidas en el semiconductor.

PCI Express Revision es la versión compatible del estándar PCI Express. Peripheral Component Interconnect Express (o PCIe) es un estándar de bus de expansión de computadora en serie de alta velocidad para conectar dispositivos de hardware a una computadora. Las diferentes versiones de PCI Express admiten diferentes velocidades de datos.

El conjunto de instrucciones es un programa difícil almacenado dentro de la CPU que guía y optimiza las operaciones de la CPU. Con estos conjuntos de instrucciones, la CPU puede funcionar de manera más eficiente. Hay muchos fabricantes que diseñan CPUs, lo que resulta en diferentes conjuntos de instrucciones, como el conjunto de instrucciones 8086 para el campamento de Intel y el conjunto de instrucciones RISC para el campamento de ARM. x86, ARM v8 y MIPS son todos códigos para conjuntos de instrucciones. Los conjuntos de instrucciones se pueden extender; por ejemplo, x86 agregó soporte de 64 bits para crear x86-64. Los fabricantes que desarrollan CPUs compatibles con cierto conjunto de instrucciones necesitan autorización del titular de la patente del conjunto de instrucciones. Un ejemplo típico es Intel autorizando a AMD, lo que permite a esta última desarrollar CPUs compatibles con el conjunto de instrucciones x86.

Intel® 64 architecture delivers 64-bit computing on server, workstation, desktop and mobile platforms when combined with supporting software.¹ Intel 64 architecture improves performance by allowing systems to address more than 4 GB of both virtual and physical memory.

PCI Express (PCIe) Configurations describe the available PCIe lane configurations that can be used to link to PCIe devices.

A PCI Express (PCIe) lane consists of two differential signaling pairs, one for receiving data, one for transmitting data, and is the basic unit of the PCIe bus. Max # of PCI Express Lanes is the total number of supported lanes.

Los procesadores Intel® vienen en cuatro tipos diferentes: canal único, canal dual, canal triple y modo flexible. La velocidad máxima de memoria admitida puede ser menor cuando se ocupan varios DIMM por canal en productos que admiten varios canales de memoria.

El tamaño máximo de memoria se refiere a la capacidad máxima de memoria admitida por el procesador.

El número de canales de memoria se refiere al funcionamiento del ancho de banda para aplicaciones del mundo real.

Max Memory bandwidth is the maximum rate at which data can be read from or stored into a semiconductor memory by the processor (in GB/s).

ECC Memory Supported indicates processor support for Error-Correcting Code memory. ECC memory is a type of system memory that can detect and correct common kinds of internal data corruption. Note that ECC memory support requires both processor and chipset support.

Intel® Virtualization Technology for Directed I/O (VT-d) continues from the existing support for IA-32 (VT-x) and Itanium® processor (VT-i) virtualization adding new support for I/O-device virtualization. Intel VT-d can help end users improve security and reliability of the systems and also improve performance of I/O devices in virtualized environments.

Intel® Virtualization Technology (VT-x) allows one hardware platform to function as multiple “virtual” platforms. It offers improved manageability by limiting downtime and maintaining productivity by isolating computing activities into separate partitions.

Intel® Standard Manageability is the manageability solution for Intel vPro® Essentials platforms and is a subset of Intel® AMT with out-of-band management over Ethernet and Wi-Fi, but no KVM or new life cycle management features.

Enhanced Intel SpeedStep® Technology is an advanced means of enabling high performance while meeting the power-conservation needs of mobile systems. Conventional Intel SpeedStep® Technology switches both voltage and frequency in tandem between high and low levels in response to processor load. Enhanced Intel SpeedStep® Technology builds upon that architecture using design strategies such as Separation between Voltage and Frequency Changes, and Clock Partitioning and Recovery.

Execute Disable Bit is a hardware-based security feature that can reduce exposure to viruses and malicious-code attacks and prevent harmful software from executing and propagating on the server or network.

Intel® AES New Instructions (Intel® AES-NI) are a set of instructions that enable fast and secure data encryption and decryption. AES-NI are valuable for a wide range of cryptographic applications, for example: applications that perform bulk encryption/decryption, authentication, random number generation, and authenticated encryption.

Intel® VT-x with Extended Page Tables (EPT), also known as Second Level Address Translation (SLAT), provides acceleration for memory intensive virtualized applications. Extended Page Tables in Intel® Virtualization Technology platforms reduces the memory and power overhead costs and increases battery life through hardware optimization of page table management.

Intel OS Guard is a security technology designed to protect operating systems from threats. It is a hardware feature built into Intel processors that helps prevent malicious code from executing in privileged modes of the operating system.
