How fast is an intel xeon processor

Lithography refers to the semiconductor technology used to manufacture an integrated circuit, and is reported in nanometer nm , indicative of the size of features built on the semiconductor. Cores is a hardware term that describes the number of independent central processing units in a single computing component die or chip. A Thread, or thread of execution, is a software term for the basic ordered sequence of instructions that can be passed through or processed by a single CPU core. Frequency is typically measured in gigahertz GHz , or billion cycles per second.

Processor Base Frequency describes the rate at which the processor's transistors open and close. The processor base frequency is the operating point where TDP is defined. CPU Cache is an area of fast memory located on the processor. A bus is a subsystem that transfers data between computer components or between computers. QPI Quick Path Interconnect links are a high speed, point-to-point interconnect bus between the processor and chipset. Thermal Design Power TDP represents the average power, in watts, the processor dissipates when operating at Base Frequency with all cores active under an Intel-defined, high-complexity workload.

Refer to Datasheet for thermal solution requirements. Embedded Options Available indicates products that offer extended purchase availability for intelligent systems and embedded solutions. See your Intel representative for details. Maximum supported memory speed may be lower when populating multiple DIMMs per channel on products that support multiple memory channels. The number of memory channels refers to the bandwidth operation for real world application. 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. Peripheral Component Interconnect Express or PCIe is a high-speed serial computer expansion bus standard for attaching hardware devices to a computer.

The different PCI Express versions support different data rates. The socket is the component that provides the mechanical and electrical connections between the processor and motherboard. Highly threaded applications can get more work done in parallel, completing tasks sooner. It offers improved manageability by limiting downtime and maintaining productivity by isolating computing activities into separate partitions.

Here, we concentrate primarily on the performance of the processors for HPC applications. Note that only a small set of codes will be capable of issuing almost exclusively FMA instructions e. The tabs below compare the features and specifications of the new model line. Intel has divided the CPUs into several groups:.

Although these processors introduce significant performance increases, technical readers will see that many of the changes are incremental: increased core counts, improved DDR memory speed, etc. In fact, in some cases the CPU frequency has been lowered from the previous models. Processor frequency and Turbo Boost behavior have changed significantly with this release.

Those metrics are discussed in further detail in the next section. With each new processor line, Intel introduces new architecture optimizations. Table 2: A comparison of some of the Xeon processor options available for Trenton Systems' SSP motherboard , used in the company's rugged servers.

Note the differences in cores, threads, CPU clock speed, cache memory and PCIe lane support between each of the processors, and when compared to the lower-end Xeon and Core processors in Table 1.

So, why are Xeon processors generally better for servers and workstations? ECC RAM helps ensure data protection by stopping corruption at the source; support for larger amounts of RAM equates to smoother application performance; more cache memory means that more data can be stored near the CPU, which keeps the CPU from having to access RAM as often; higher core and thread counts means more processing units to divvy up computational workload and faster computation in general; having dual CPUs ensures that systems have the power of two Xeon CPUs sporting each of the previously listed benefits; and support for more PCIe lanes means support for more high-speed expansion components, such as dedicated GPUs.

Most customers in the market for a server with a Xeon motherboard value the above advantages because they provide data protection, high-speed expansion capabilities, faster computation, and speedy, consistent performance, all of which are especially desirable features for systems supporting mission-critical applications, whereby a loss of data, decline in system performance or inability to expand could result in disastrous consequences. But Core CPUs also have their advantages, too - in particular, overclocking capabilities and integrated graphics.

Why are these advantages important? Faster clock speeds mean quicker CPU calculations, which, in turn, equates to smoother application performance, and the inclusion of on-board graphics means you may not need to purchase a dedicated graphics card.

This is entirely dependent on the needs of your program or application, of course, as some high-end applications benefit significantly from the performance associated with a dedicated graphics card. High-end military, industrial and business-related programs and applications need the speed, data protection, longevity and reliability that a Xeon server can offer.
