Description Product Information The 728955-B21 HPE Intel Xeon processor is a high-performance component designed for use in servers, specifically the HPE Proliant DL580 Gen8 server. This processor has 15 cores and operates at a speed of 2.8GHz. It comes with 37.5MB of L3 cache and a QPI speed of 8GT/s. The processor is built on a 22nm fabrication process and has a thermal design power (TDP) of 155W. In this article, we will explore the technical details of this processor and explain what each of these terms means. What is a Processor A processor is the central processing unit (CPU) of a computer system. It is the component responsible for executing instructions from software applications and performing calculations to produce the desired results. The processor communicates with other components, such as memory and storage, to carry out its tasks. What is the Intel Xeon Processor The Intel Xeon processor is a family of high-performance processors designed for use in servers and workstations. These processors are designed to handle complex computing tasks, such as those required for scientific simulations, data analysis, and video rendering. They have multiple cores, which allows them to execute multiple instructions at the same time, and they come with a large amount of cache memory to speed up data access. What is a 15-Core Processor A 15-core processor is a processor that has 15 individual processing units, called cores. Each core can execute instructions independently of the other cores, which allows for multiple tasks to be executed at the same time. This can lead to improved performance in applications that are designed to take advantage of multiple cores. What is Processor Speed Processor speed refers to the rate at which a processor can execute instructions. It is measured in GHz, or gigahertz, which represents billions of cycles per second. The higher the processor speed, the faster it can execute instructions. What is Cache Memory Cache memory is a type of memory that is used to speed up data access by storing frequently used data closer to the processor. This reduces the time it takes for the processor to access the data, which can lead to improved performance. What is L3 Cache L3 cache is a type of cache memory that is larger and slower than L1 and L2 cache. It is used to store data that is accessed less frequently but is still important for performance. The larger the L3 cache, the more data that can be stored closer to the processor, which can lead to improved performance. What is QPI Speed QPI speed refers to the speed at which the processor communicates with other components in the computer system, such as memory and storage. It is measured in GT/s, or gigatransfers per second. The higher the QPI speed, the faster the processor can communicate with other components, which can lead to improved performance. What is Socket FCLGA 2011 Socket FCLGA 2011 is a type of processor socket that is used to connect the processor to the motherboard. This particular socket is designed to work with the Intel Xeon processor and is compatible with the HPE Proliant DL580 Gen8 server. What is Fabrication Process Fabrication process refers to the manufacturing process used to create the processor. This process involves building the processor from individual components, such as transistors and wires, on a silicon wafer. The smaller the fabrication process, the more transistors can be packed onto the processor, which can lead to improved performance. What is Thermal Design Power Thermal Design Power (TDP) is a measure of the maximum amount of heat that a processor can dissipate. It is measured in watts (W) and is an important consideration when selecting a processor for.
