Description
Product Specifications
The 878661-B21 is a central processing unit (CPU) manufactured by Hewlett Packard Enterprise (HPE) and designed for use in high-performance computing systems. The CPU features an Intel Xeon Platinum 8176 processor with 28 cores, 56 threads, and a base clock speed of 2.1GHz. The CPU also has a massive 38.5MB of L3 cache memory and uses the FCLGA3647 socket for installation. The 14nm manufacturing process used in the production of the CPU ensures low power consumption, and the processor has a thermal design power (TDP) of 165 watts. In this article, we will delve deeper into the features of this processor and what it means for high-performance computing systems.
The Processor’s Architecture
The Intel Xeon Platinum 8176 processor used in the 878661-B21 CPU is built on the Skylake architecture, which is a successor to the Broadwell architecture. The Skylake architecture features improvements in clock speeds, memory support, and power consumption over its predecessors. It also includes support for new instruction sets, such as AVX-512, which can help improve performance in certain types of applications.
The 28 cores in the Xeon Platinum 8176 processor are arranged in a two-die configuration, with each die containing 14 cores. This design helps to improve the processor’s scalability and allows it to handle more workloads simultaneously. The processor also has 56 threads, which means it can handle 56 tasks simultaneously with the help of hyper-threading technology.
Cache Memory
The 878661-B21 CPU comes with a massive 38.5MB of L3 cache memory. Cache memory is a type of memory that is integrated into the processor to improve performance by reducing the time it takes to access frequently used data. L3 cache is the largest and slowest type of cache memory, but it is still much faster than accessing data from the main memory.
The large amount of L3 cache memory in the 878661-B21 CPU means that the processor can access frequently used data faster, which can result in better performance in applications that require a lot of data processing. For example, in high-performance computing systems used in scientific research or financial analysis, the CPU’s large L3 cache memory can help improve the speed of data analysis.
Socket and Power Consumption
The 878661-B21 CPU uses the FCLGA3647 socket, which is a socket designed for server-grade processors. The FCLGA3647 socket has a larger number of pins than the consumer-grade LGA1151 socket, which allows for better power delivery and heat dissipation.
The 878661-B21 CPU has a TDP of 165 watts, which means it consumes a lot of power when compared to consumer-grade CPUs. However, this high power consumption is necessary to support the high-performance computing tasks for which the CPU is designed. The 14nm manufacturing process used in the production of the processor ensures that power consumption is kept to a minimum while still maintaining high performance.
Applications
The 878661-B21 CPU is designed for use in high-performance computing systems used in scientific research, financial analysis, and other data-intensive applications. It is also suitable for use in virtualization, cloud computing, and other server-based applications that require high processing power.
In scientific research, the CPU can be used for tasks such as simulations, modeling, and data analysis. Financial institutions can use the CPU to perform high-speed trading, risk analysis, and other data-intensive tasks. In virtualization, the CPU can be used to create multiple virtual machines that can run simultaneously on a single physical server, which can help reduce hardware costs and improve efficiency.
Summary, The HPE Intel Xeon 28 Core Platinum 8176 processor is a powerful computing solution designed for use in enterprise-level servers.
