SRV5E Intel Xeon 6 6787P 2.00GHz 86-Core 336MB 350W CPU Processor

Intel SRV5E Xeon 6 6787P Processor

The Intel Xeon 6 processor family represents a fundamental shift in data center CPU strategy, bifurcating into two specialized lines: the E-core (Efficiency-core) Sierra Forest and the P-core (Performance-core) Granite Rapids architectures. The Intel Xeon 6 6787P is a flagship processor from the latter, the Granite Rapids family, engineered explicitly for maximum single-threaded and all-core performance in the most demanding computational workloads. Unlike its E-core counterparts that prioritize core density and power efficiency for highly parallel, scale-out applications, the 6787P leverages the raw, unimpeded power of Performance-cores to drive through complex, latency-sensitive tasks where sheer processing muscle per core is paramount.

Capabilities

This architectural choice positions the 6787P as the ideal solution for databases, Capabilities high-frequency trading platforms, complex simulations, and large-scale ERP systems. The P-cores feature deeper out-of-order execution pipelines, higher clock speeds, and larger dedicated caches per core compared to E-cores, Capabilities ensuring that single-threaded applications—which still form the backbone of many enterprise-critical services—do not become a system bottleneck. The platform is built on the Intel 3 process node, delivering significant improvements in transistor performance and power efficiency over previous generations, even as it pushes the performance envelope to new heights.

Deep Dive into Core Specifications and Performance

86 Cores of Unbridled Parallel Processing

At the heart of the SRV5E Xeon Intel 6 6787P are 86 powerful Performance-cores. This massive core count is not merely a numbers game; it represents a paradigm shift in what is possible within a single socket. For workloads that can be effectively parallelized—such as rendering farms, computational fluid dynamics, financial risk modeling, and genomic sequencing—the SRV5E 6787P can deliver a dramatic reduction in time-to-results. By consolidating workloads that previously required multiple older servers, organizations can achieve greater rack density, simplify their infrastructure, and reduce total cost of ownership (TCO) while simultaneously boosting computational throughput.

The 336MB L3 Cache

One of the most defining features of the Intel SRV5E 6787P is its enormous 336MB of shared L3 cache. In a many-core processor, keeping all the cores fed with data is a critical challenge. A large, unified L3 cache acts as a massive, high-speed reservoir for data that is actively being processed. This drastically reduces the number of times the cores must wait for data to be fetched from the much slower main memory (RAM). For data-intensive applications like in-memory databases (e.g., SAP HANA), large dataset analytics, and virtualization with many active virtual machines, this vast cache significantly reduces latency, increases transaction throughput, and ensures smooth, predictable performance even under extreme load.

Thermal Design

The 350W TDP rating of the Intel 6787P is a key specification that system builders and data center operators must carefully plan for. TDP represents the average power, in watts, that the processor dissipates while operating at its base frequency under a complex, high-utilization workload. It is a crucial metric for designing cooling solutions and power delivery infrastructure. A 350W TDP necessitates a high-performance server chassis with robust, redundant airflow and a server-grade cooling solution capable of continuously removing this significant amount of heat to prevent thermal throttling and maintain system stability.

Target Workloads and Real-World Applications

In the HPC domain, the Intel 6787P is a computational powerhouse. Its 86 cores are ideally suited for distributed-memory parallel computing models like MPI (Message Passing Interface), where each core can be assigned a portion of a larger scientific computation—be it climate modeling, molecular dynamics, or astrophysical simulations. While dedicated GPUs handle the bulk of AI training, the 6787P serves as a formidable host CPU for AI inference workloads and for mixed-workload environments where data pre-processing, model serving, and traditional HPC tasks run concurrently. Its support for AVX-512 instructions accelerates vector-based calculations common in scientific and AI code.

Memory-Intensive Databases and Analytics

SRV5E Intel the combination of 86 cores, a 336MB cache, and eight channels of DDR5 memory makes the 6787P a natural fit for in-memory database management systems (DBMS) like SAP HANA, Oracle Database In-Memory, and SQL Server. These systems rely on holding the entire dataset in RAM for ultra-fast transaction processing and analytics. The 6787P's architecture ensures that the database engine can process transactions and queries at immense speed, with the large cache serving as a critical buffer to keep the cores saturated with work. For big data analytics frameworks like Apache Spark, the CPU can rapidly process in-memory data partitions, enabling real-time insights from massive datasets.

Reliability

For mission-critical deployments, the SRV5E Xeon Intel 6 6787P is engineered with a comprehensive suite of RAS features. These include machine check architecture recovery, which allows the system to recover from otherwise fatal uncorrected errors, and enhanced patrolling scrubbers that proactively find and correct soft errors in memory and cache. Combined with support for Error Correcting Code (ECC) DDR5 memory, these features maximize system uptime and ensure data integrity, which is non-negotiable in financial, healthcare, and enterprise resource planning applications.

Xeon 6 6787P vs. E-core

The decision between a P-core processor like the Intel SRV5E 6787P and an E-core variant from the Sierra Forest line is a strategic one, dictated by workload characteristics. Choose the 6787P when your primary constraint is the speed of individual tasks (low latency) or the performance of legacy applications that cannot be easily parallelized. Choose an E-core processor when your workload is highly parallelizable, consists of many small, independent tasks (e.g., web hosting, media transcoding, scale-out storage), and the primary goal is to maximize throughput per watt and per rack unit.

Compatibility

The Intel SRV5E 6787P is designed for the LGA 7529 socket, a substantial increase in pin count from previous generations Compatibility. This expanded socket is necessary to support the significantly higher core counts, increased memory channels, and expansive I/O capabilities of the Xeon 6 platform. It ensures robust power delivery for a 350W TDP and clean, high-speed signaling for the eight channels of DDR5 memory and 80 lanes of PCI Express 5.0. Investing in this platform provides a forward-looking infrastructure, capable of supporting not only current-generation processors but also future iterations within the Xeon 6 family, protecting capital expenditure and enabling seamless future upgrades.
