Intel Xeon 6788P — High-Density Granite Rapids Processor for Balanced HPC, Analytics and Enterprise Platforms

Intel Xeon 6788P is designed for organizations that need extremely high core density and memory scalability, but with a more balanced operating profile compared to the most power-aggressive flagship SKUs. Positioned within the Intel Xeon 6 Granite Rapids family, this processor delivers 86 cores and 172 threads, making it an ideal foundation for dense compute nodes where throughput, memory bandwidth and platform flexibility are equally critical.

The 6788P operates at a 2.0 GHz base frequency with turbo frequencies reaching 3.8 GHz, offering a meaningful uplift for latency-sensitive tasks compared to ultra-low turbo parts. This frequency envelope allows the processor to handle mixed workloads efficiently, where massively parallel execution runs alongside orchestration, scheduling, and control-plane services.

Built on Granite Rapids P-cores and produced using Intel 3 process technology, the Xeon 6788P focuses on sustained performance rather than short-lived boost behavior. This makes it particularly effective for long-running compute jobs such as scientific simulations, financial risk modeling, batch analytics, and large-scale ETL pipelines.

Memory capability is a central strength of this processor. The Xeon 6788P supports 8 DDR5 memory channels with official support for DDR5 up to 6400 MT/s and total memory capacity reaching 4 TB. This configuration allows system architects to design nodes that keep large datasets resident in memory, reducing I/O pressure and improving end-to-end job completion times.

From an I/O perspective, the Xeon 6788P offers PCIe 5.0 connectivity with up to 88 PCIe lanes, enabling high-bandwidth attachment of GPUs, NVMe storage arrays, and high-speed network adapters. This is particularly valuable for hybrid CPU–GPU systems, storage-heavy analytics nodes, and clustered environments where network throughput is a limiting factor.

Power consumption is rated at 350 W, placing the Xeon 6788P firmly in the high-performance server category. This level of power draw requires well-engineered cooling solutions and robust power delivery, but it also reflects the processor’s ability to sustain high all-core workloads without aggressive throttling.

Security and platform features align with modern data center requirements, including advanced hardware-level isolation, memory protection technologies, and support for secure multi-tenant deployments.

Typical deployment scenarios include dense HPC nodes, large-scale analytics platforms, in-memory databases, enterprise virtualization environments, and hybrid CPU–GPU systems for AI preprocessing and inference.

Compared to lower-core Granite Rapids models, the Xeon 6788P significantly increases throughput per socket while preserving flexibility in memory and I/O design, making it a strong choice for mixed and production-grade workloads that demand both scale and responsiveness.
