Intel announced the Xeon 6700P and 6500P P-core processor families, based on Granite Rapids-SP, on February 24, 2025. The launch-era ServeTheHome first look centers on a single-socket Xeon 6781P system, not a broad test of every SKU or a like-for-like dual-socket comparison. Its results should be read with that setup—and a reduced memory speed caused by the test system’s 16-DIMM, 1 TB configuration—in mind.
What are the Xeon 6700P and 6500P?
They are P-core server processor families in Intel’s Xeon 6 lineup, built on Granite Rapids-SP. Intel’s February 2025 brief describes the two tiers as addressing different segments: 6700-series for a range of data-center and telco environments, and 6500-series for mainstream servers and edge deployments. That is Intel’s product positioning, not an independent finding that one tier is faster or better for every workload.
The family brief lists up to 86 cores per socket, support for one-to-eight-socket systems, DDR5-6400 support, and 136 PCIe lanes for the single-socket variant. Those are family-level maximums and capabilities, not a promise that each processor or server exposes them all. Check the exact SKU and server documentation before using any of these figures to plan a system. Intel’s Xeon 6700/6500 P-core product brief has the family-level specifications.
What does the first look’s test setup establish?
ServeTheHome’s February 24, 2025 launch review used a last-minute, single-socket R1S system with an Intel Xeon 6781P. The publication said it had not received a dual-socket CPU set, so this initial test was not a dual-socket evaluation. The review therefore provides a look at one processor and platform configuration, rather than a representative performance result for every 6700P or 6500P model.

#1 Best Overall
- Intel Xeon E5-2699 V4 Docosa-core (22 Core) 2.20 Ghz Processor - Socket Lga 2011-v3 - 5.50 Mb - 55 Mb Cache - 64-bit Processing - 14 Nm - 145 W
The system had 1 TB of memory installed across 16 DIMMs. ServeTheHome noted that this population lowered memory speed and said its test scripts had to be rerun beginning Saturday morning. Memory rate and population can affect performance, so results from that setup should not be treated as measurements from a maximum-speed or otherwise optimized memory configuration. ServeTheHome’s first look describes the test platform and this caveat.
How fast is Granite Rapids-SP?
The useful answer from this launch review is bounded: it offers initial results from a single Xeon 6781P system under the conditions above. It does not establish a complete ranking of the 6700P and 6500P lineup, an optimized result for every memory population, or a broad comparison with competing server CPUs. To compare systems fairly, match the processor SKU, socket count, memory type and DIMM population, power conditions, and software workload.
Rank #2
Intel’s launch announcement claimed 1.4× average performance versus the previous generation across a range of enterprise workloads. That is Intel’s vendor-reported comparison, not a result measured by ServeTheHome in its single-socket review. Intel also published workload-specific AI and consolidation comparisons; those claims should be interpreted within the compared systems and workloads, not as universal performance multipliers. Intel’s February 24, 2025 launch announcement contains the vendor’s claims.
What is the difference between 6700P and 6500P?
In the launch materials, the clearest distinction is intended market segment: Intel places the 6700 tier toward data-center and telco workloads, while the 6500 tier is positioned for mainstream servers and edge use. The family-level material does not make that segmentation a substitute for SKU-level comparison. For a purchasing or design decision, compare the exact models’ core counts and frequencies, then validate socket support, memory configuration, and I/O against the server platform.
Rank #3
- Part Number Identification: CD8069504194501 for easy reference and compatibility verification
- CPU Series Specification: 2nd Generation Intel Xeon Scalable processor from the Gold 6000 series
- Processor Frequency: 3.10GHz base clock speed with 18 cores for high-performance computing tasks
- Package Type: OEM tray processor without retail packaging
- Cooling Device Notice: Processor only, cooling device not included and must be purchased separately
ServeTheHome characterizes 6500P as the lower-end Granite Rapids-SP tier and flags uncertainty around some detailed lane and UPI-link information. Avoid inferring lane counts or link configurations from the family name alone; verify the exact processor and platform specification. Intel ARK’s Granite Rapids list includes the Xeon 6781P as a Q1 2025 product and now includes later models and launch quarters, so the product lineup visible today extends beyond the launch-era review. Intel ARK’s Granite Rapids product list is the place to check current SKU listings.
Which server platform supports these processors?
The family brief discusses single-socket I/O and multi-socket scalability, but it does not establish that any generic server board will support a particular Xeon SKU. Compatibility depends on the specific processor and server implementation, including socket, firmware, memory support, and board configuration. Confirm the server manufacturer’s compatibility documentation for the exact processor before selecting a platform; do not rely on family-level figures alone.

What should you compare before choosing a system?
- Workload and tier: Determine whether the intended use aligns with Intel’s 6700 data-center/telco positioning or 6500 mainstream server/edge positioning.
- Exact processor: Compare the specific SKU’s cores and frequency rather than assuming every family member reaches the stated maximum.
- Socket and I/O needs: Decide whether single-socket density or multi-socket scalability matters, then verify the platform’s actual PCIe and interconnect implementation.
- Memory setup: Check supported DDR5 rate and the effects of DIMM count and population for the particular system.
- Benchmark comparability: Use results from systems with comparable socket count, memory, power settings, and software workload; separate Intel’s launch claims from independent measurements.
Intel’s launch announcement also included this characterization from Michelle Johnston Holthaus, then identified as interim co-CEO of Intel and CEO of Intel Products: “We are intensely focused on bringing cutting-edge leadership products to market that solve our customers’ greatest challenges and help drive the growth of their business,” she said on February 24, 2025. “The Xeon 6 family delivers the industry’s best CPU for AI and groundbreaking features for networking, while simultaneously driving efficiency and bringing down the total cost of ownership.” The claims about leadership, AI, and cost are Intel’s own description of its products.
