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.


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.

About New Bulk Pack Products

New Bulk Pack products come with clamshell boxes and do not have any manufacturer warranty. Many times manufacturers disassemble whole units to use parts or pulled from a new system. Typically, this product doesn't come with software or instructions unless indicated and no Manufacturer’s genuine warranty. You can take note these are not brand new products.

The Intel 28 core is the record-breaker with the highest number of cores in Intel's processor families and generations. With 28 cores and up to 56 threads, this CPU is a monstrous processor designed for very workload-intensive applications such as 3D game development and rendering, industrial designs, and high-quality video editing. They are purposefully designed for workstations and servers that are handling data-hungry loads.

Designed for Professional-Grade Developers

The 28 core processor has about 38.5 MB of level 3 cache memory, up to 68 PCI-express next-gen 3.0 lanes, and other high-performance features. Computers with this processor can have DDR4 RAM to better improve performance. Being the latest CPU model from Intel Corporation, not many people have it in their systems. You take advantage of this and being among the first people to upgrade.

Created for Multithreading Applications

Just like its predecessors, Intel 28 core processors are designed to better run multithreaded applications. With 28 independent cores and 56 threads, even the most demanding applications will run as expected. And what's more? You can get things done faster by overclocking the processor. The good news is that you can do it with confidence because of the performance tuning protection plan. The mission-critical workloads are channeled to cores with the fastest clock speeds for enhanced performance, even on multithreaded tasks.

Ultimate Protection to Your System

The 28 core Intel Xeon can help protect your system through error-correcting code memory support. This can help save your system from crashes and data corruption that might lower reliability. The current demands are that a data center is continuously running while delivering the expected performance. With a 28 core processor, you can be sure of data integrity, made possible through timely fault avoidance, detection, and correction. That is an intelligent system built in this CPU to make your servers and workstations more manageable. Any fault occurrences can be easily identified and reconfigured through a built-in RAS.
