Product overview of the HPE P02976-B21

P02976-B21 is a product code for a processor made by Hewlett Packard Enterprise (HPE). It is a type of central processing unit (CPU) which is designed for use in high-performance servers and workstations. The processor is made by Intel, a well-known manufacturer of computer hardware components. In this article, we will be discussing the specifications and features of the P02976-B21 processor in detail.

CPU Model

The P02976-B21 processor belongs to the Intel Xeon Platinum 8256 family. It is a quad-core processor, meaning it has four processing cores. Each core can execute instructions independently, which allows for parallel processing and faster performance. The Platinum 8256 model has a base clock speed of 3.8GHz, which means that it can execute 3.8 billion cycles per second. This clock speed can be increased using Intel's Turbo Boost technology, which allows the processor to automatically increase its clock speed when needed.

Smart Cache

The P02976-B21 processor has a Smart Cache of 16.5MB. Cache is a type of memory that stores frequently used data and instructions for quick access. The Smart Cache feature of the P02976-B21 processor dynamically allocates cache to each processing core based on the workload, which helps to maximize performance.

UPI Speed

The P02976-B21 processor has a UPI (Ultra Path Interconnect) speed of 10.4GT/s. UPI is a high-speed interconnect technology that connects the processor to other components in the system, such as other processors or memory modules. A faster UPI speed means that data can be transferred more quickly between components, which can improve system performance.

Socket Type

The P02976-B21 processor uses the Socket FCLGA3647 socket type. A socket is a physical interface between the processor and the motherboard. The Socket FCLGA3647 socket type is designed for high-end server and workstation systems, and it supports features such as multiple processors and large amounts of memory.

Manufacturing Process

The P02976-B21 processor is manufactured using a 14nm (nanometer) process. This refers to the size of the transistors on the processor. A smaller manufacturing process allows for more transistors to be packed onto the processor, which can improve performance and reduce power consumption.

Thermal Design Power

The P02976-B21 processor has a Thermal Design Power (TDP) of 105W. TDP is a measure of the maximum amount of heat that the processor is expected to generate under normal operating conditions. It is important to choose a cooling solution that can dissipate this amount of heat to prevent the processor from overheating and causing damage to the system.

In summary, the P02976-B21 HPE Intel Xeon Quad-Core Platinum 8256 3.8GHz 16.5MB Smart Cache 10.4GT/S UPI Speed Socket FCLGA3647 14NM 105W Processor is a high-performance processor designed for use in server and workstation systems. It has four processing cores, a base clock speed of 3.8GHz, and a Smart Cache of 16.5MB. It uses the Socket FCLGA3647 socket type and has a UPI speed of 10.4GT/s. The processor is manufactured using a 14nm process and has a TDP of 105W. Overall, the P02976-B21 processor is a powerful and efficient choice for high-end computing applications.
