Product description

Intel Xeon 6761P — 64-core Granite Rapids CPU with MRDIMM support for bandwidth-critical enterprise, AI, and technical workloads

The Intel Xeon 6761P stands out inside the Granite Rapids Xeon 6 family due to its combination of high compute density, expanded memory technology support, and a performance envelope tuned for workloads that must sustain high throughput without interruptions. While structurally similar to the 6760P, this model introduces MRDIMM capability and a higher turbo ceiling, making it an especially strong choice for organizations building next-gen data engines, AI inference pipelines, and multi-tenant compute clusters with strict QoS requirements.

At its core, the 6761P delivers 64 cores, 128 threads, 2.5 GHz base frequency and up to 3.9 GHz turbo, providing a more responsive top-end compared to its non-MRDIMM sibling. This benefits real-time analytics, low-latency financial workloads, and inference services where short-duration bursts of elevated performance significantly impact user experience and SLA consistency.

A major architectural highlight is its 336 MB of L3 cache, one of the largest cache configurations within Granite Rapids. This enormous shared pool enhances stability in workloads with unpredictable memory access patterns—large graph engines, distributed object stores, simulation frameworks, columnar DBMS scans, and Python-based data science pipelines. When multiple high-pressure operations run concurrently on the same socket, this cache capacity reduces cross-service interference, improving determinism and reducing tail latency.

Memory capabilities are where the Xeon 6761P differentiates itself. Alongside standard DDR5-6400 support, it introduces MRDIMM (Multiplexed Rank DIMM) compatibility, enabling even higher memory throughput (up to 8000 MT/s depending on configuration). This matters for workloads such as vector databases, real-time recommendation engines, LLM-powered microservices, and large-scale scientific datasets where bandwidth saturation is a frequent bottleneck. With up to 4 TB of RAM per socket, memory-bound jobs can run fully in-memory, significantly reducing compute stalls and I/O pressure.

I/O performance is equally modern: 112 PCIe 5.0 lanes allow dense configurations of NVMe SSDs, SmartNICs, GPGPU accelerators, FPGA cards, and high-speed networking adapters. For AI and HPC-lite applications that depend heavily on accelerator topologies, PCIe 5.0 ensures predictable bandwidth allocation even under multi-device load.

At 350 W TDP, the Xeon 6761P is engineered for sustained high utilization in modern thermal envelopes. Server builders targeting 1U and 2U designs can rely on predictable thermals, making it viable for cloud compute nodes where thousands of machines must maintain uniform performance profiles without thermal drift.

In real-world deployments, the 6761P excels in:

  • AI inference clusters supporting large numbers of concurrent queries
  • High-bandwidth analytic engines (ClickHouse, BigQuery-style systems, Spark SQL)
  • Memory-intensive microservices including vector search, caching layers and JVM workloads
  • High-density virtualization clusters with mixed application footprints
  • Compute-heavy R&D environments such as simulation and genome analysis
  • Multi-GPU servers relying on PCIe 5.0 throughput

Overall, the Xeon 6761P is designed for organizations requiring a high-core, high-bandwidth CPU that remains stable under pressure and supports emerging memory innovations shaping modern computing.

Analysis of Intel Xeon 6761P Technical Specifications

Based on the technical parameters, the Intel Xeon 6761P demonstrates clear architectural superiority in the following aspects:

  • Leadership in base frequency within the 64-core class: With a figure of 2.5 GHz, the 6761P model outperforms direct competitors with a similar core count: 6767P (2.4 GHz), 6768P (2.4 GHz), and 6760P (2.2 GHz). This ensures consistently high throughput when executing prolonged background computations that do not require transitioning to turbo mode.
  • Maximum L3 cache capacity: The processor boasts 336 MB of cache, which is the upper limit for the Granite Rapids architecture. In this metric, it surpasses the 48-core chips (the 6747P and 6741P have 288 MB each, the 6748P has 192 MB) and the baseline 64-core 6760P (320 MB). The massive cache radically reduces memory access latency in complex databases and graph computations.
  • Aggressive Turbo Boost at high density: The combination of 64 cores with the ability to accelerate up to 3.9 GHz makes this chip a versatile tool. It reacts faster to peak load spikes than multi-core flagships like the 86-core 6787P (3.2 GHz) and 6788P (3.8 GHz). The 350 W thermal package is entirely justified by its outstanding peak and sustained performance.

Conclusion

The Intel Xeon 6761P is an uncompromising choice for large-scale data centers that require the simultaneous processing of thousands of threads without losing speed on each individual core. Occupying the niche of premium 64-core solutions, it prevails over competitors thanks to a class-leading base frequency (2.5 GHz), powerful turbo acceleration (3.9 GHz), and a giant cache pool of 336 MB, providing the infrastructure with a reliable margin of safety for resource-intensive tasks.

Product FAQ

This processor offers a unique engineering balance: an impressive 64 physical cores operate at an increased base clock speed of 2.5 GHz. This ensures consistently high performance for resource-intensive background services and continuous workloads without the need for continuous activation of Turbo Boost mode, which favorably distinguishes it from counterparts with lower starting frequencies.

The integration of MRDIMM technology allows achieving phenomenal RAM bandwidth—up to 8000 MT/s. For enterprise In-Memory databases and artificial intelligence preprocessing platforms, this means lightning-fast access to arrays of information. Such speed eliminates situations where the RAM subsystem becomes a factor holding back the overall computing speed of the server.

Such an array of Level 3 cache is critically important for systems with unpredictable data access patterns, for example, for graph DBMS, complex analytical platforms, or recommendation systems. The processor is capable of holding huge volumes of active indexes right on the die, radically reducing latency and ensuring smooth operation even during peak loads from thousands of simultaneous users.

Absolutely. The platform provides engineers with dozens of available lanes of the advanced PCIe 5.0 standard. This reserve is more than enough for the direct connection of the latest NVMe drives, hardware compute accelerators, and 100/200 Gbps class network adapters. The hardware bus is guaranteed not to act as a limiting barrier during horizontal or vertical infrastructure scaling.

A TDP value of 350 W is a working standard for flagship solutions of this level of compute density. An emergency transition to expensive liquid cooling loops is not mandatory. The processor functions reliably and safely in classic rack chassis (2U and up) equipped with high-quality, high-density air heatsinks and properly configured airflow.

This is one of the most effective tools for creating dense hypervisors. Having 128 compute threads allows IT departments to host dozens of demanding, isolated machines on a single physical server. Strict hardware segmentation of the giant cache reliably protects the processes of guest systems from mutual interference, guaranteeing the uninterrupted fulfillment of strict corporate SLAs.

Yes, the Granite Rapids microarchitecture includes built-in Intel AMX (Advanced Matrix Extensions) matrix accelerators. Combined with 64 high-frequency cores and ultra-fast memory, the central processor excellently handles tasks of inference, semantic search, and stream analytics, allowing companies to optimize the budget on purchasing dedicated graphics accelerators for basic AI workloads.

The presence of the “P” suffix in the designation explicitly indicates the processor’s optimization for single-socket systems. Deploying such a server completely rids the architecture of memory synchronization delays (NUMA penalties) that occur when exchanging data between two separate physical processors. Additionally, this makes it possible to significantly reduce the costs of licensing commercial software, the price of which is tied to the number of sockets.

Deploying a new computing base will require the purchase of current server platforms. The chip is installed into the modern LGA 4710 microprocessor socket. The change of socket is a strict engineering necessity dictated by the implementation of support for the latest MRDIMM memory, the high-speed PCIe 5.0 bus, and updated hardware protocols for protecting the infrastructure against cyber threats.
