Intel Xeon 6781P

The Intel Xeon 6781P is an active server/workstation processor in Intel’s Xeon 6 (Granite Rapids-SP) generation, released on 2025-02-23. It is built for Intel Socket 4710 on a 5 nm process at Intel, with a die size of 2x 598 mm². The part provides 80 cores, 160 threads, 112 KB of L1 cache per core, 2 MB of L2 cache per core, and 336 MB of shared L3 cache. Its launch MSRP is $8960.

Benchmark Performance

The supplied benchmark data is sparse. The benchmarks array is empty, the average benchmark score is 0, and the nearestRivals array contains no entries. No direct measured scores or rival deltaPct values can be cited from this record. The only relative ranking signal present is percentileVsAllCpus: 50, which places this processor at the 50th percentile of the database’s distribution across all CPUs. That median placement is not a measured score; it is a classification position. With no benchmark scores in the record, performance analysis must rest on the architectural specifications.

The 80-core, 160-thread configuration is the dominant throughput indicator. The shared L3 cache is 336 MB, which is an unusually large pool for all cores to draw on. Memory bandwidth is listed at 409.6 GB/s over an eight-channel DDR5 bus, which is the kind of memory path required to keep 80 cores fed. PCIe connectivity is Gen 5 with 136 CPU-only lanes, providing substantial expansion and I/O capacity. These specifications point to a processor designed for parallel, memory-intensive server workloads rather than lightly threaded desktop tasks.

Because no benchmark scores exist in the record, no percentage leads or deficits can be reported. The data shows a processor whose ranking is centered at the 50th percentile, but with an empty score list, the practical interpretation is that the database has not yet recorded direct performance measurements for this SKU. The structural data, however, is unambiguous: this is a high-core-count, high-bandwidth server part.

How It Compares

The nearestRivals field is empty. There are no rival names, no rival scores, and no deltaPct values available for the Intel Xeon 6781P. As a result, no comparison paragraphs against specific competitors can be generated from the supplied record. The only comparative metric is the all-CPU percentile of 50, which is a median position within the database. This indicates that the processor is not currently plotted as an extreme high or low performer in the record.

Without nearest-rival entries, any numeric comparison to other processors would rely on data outside this pack. The database does not provide a rival set for this SKU, so the appropriate conclusion is that no direct competitor deltas exist in the benchmark database. The processor stands alone in the supplied data, with its architectural specifications serving as the primary basis for positioning.

Platform and Compatibility

The Intel Xeon 6781P uses Intel Socket 4710. Its architecture is Granite Rapids, matching the codename Granite Rapids, within the Xeon 6 (Granite Rapids-SP) generation. The processor is manufactured by Intel on a 5 nm process, with a die configuration of 2x 598 mm². The market segment is explicitly Server/Workstation, and production status is Active.

Memory support is DDR5 on an eight-channel memory bus. The listed memory bandwidth is 409.6 GB/s, and ECC memory is supported. This makes the platform suitable for memory-heavy workloads where data integrity matters. Expansion is handled through PCIe Gen 5 with 136 CPU-only lanes, meaning the CPU itself supplies the lane count rather than relying on chipset-derived lanes in this record.

There is no integrated graphics field populated for this processor, so a discrete graphics adapter is required for any display output. The multiplier is locked, so user-controlled overclocking is not enabled. The part number is SRV5J. The platform compatibility picture is therefore straightforward: it is a Socket 4710, Granite Rapids-SP server/workstation processor with locked multiplier, no integrated graphics, and a large PCIe lane count supplied directly from the CPU.

Who Should Consider It

Given the absence of benchmark scores, recommendations are grounded in the listed specifications rather than measured results. The 80-core, 160-thread design with 336 MB of shared L3 cache makes this processor a candidate for highly parallel compute workloads. Server virtualization, large-scale batch processing, database workloads, and multi-threaded scientific or engineering calculations are the kinds of tasks that can use 160 threads and a large shared cache. The eight-channel DDR5 memory subsystem with 409.6 GB/s of bandwidth reinforces the target use case: feeding many cores with large datasets.

For content creation and rendering workloads that scale across threads, the thread count is the main asset. The large L3 cache and high memory bandwidth support working sets with substantial data residency. For gaming, the record contains no gaming benchmark, and the absence of integrated graphics means a discrete GPU is mandatory. The server/workstation market segment also points away from desktop gaming as a primary use.

For general office workflows, this processor is far more powerful than needed. 80 cores and 160 threads are well beyond typical office productivity requirements, and no office-specific benchmark scores are supplied. The active production status and server/workstation segment mean the intended buyer is someone integrating a high-end server or workstation platform, not a conventional office desktop. Workloads that can use large core counts, high memory bandwidth, and massive shared cache will get the most from this part.

Power and Thermals

The TDP is 350 W. That is a high thermal class for a server processor. The thermal solution must be designed for sustained operation under heavy all-core load, because all 80 cores can be active simultaneously. The base clock is 2000.00 and the boost clock is 3.80, so the processor has a wide operating range, but the power envelope is defined by the 350 W TDP.

The die configuration is 2x 598 mm², meaning the processor uses two large dies in the package. That still results in a 350 W thermal design. No cooler is specified in the record, so the cooling tier is implied by the platform: a Socket 4710 server or workstation motherboard should be paired with cooling capable of handling a 350 W-class processor. Chassis airflow, heatsink capacity, and thermal management are all critical given this TDP. The active production status indicates that this 350 W thermal specification is a current part of the product definition.

Single-Thread vs Multi-Thread Behavior

The clock data in the record shows a base clock of 2000.00 and a boost clock of 3.80. The multiplier is locked, so these are fixed operating points. The multi-thread capability is the dominant characteristic of the Intel Xeon 6781P: 80 cores and 160 threads provide far more parallelism than the frequency figures alone would suggest.

Each core has dedicated local cache, with 112 KB of L1 cache per core and 2 MB of L2 cache per core. The shared L3 cache is 336 MB. The per-core caches support each individual core with local data storage, while the large shared L3 gives all cores access to a common pool. The single-thread ceiling is represented by the 3.80 boost clock, which is the highest frequency listed. However, no measured single-thread benchmark score is present in the record.

The contrast between the modest boost clock and the enormous thread count indicates a processor tuned for parallel throughput. Workloads that use fewer threads will depend on the 3.80 boost clock and per-core cache, but the record does not quantify that kind of performance. Multi-thread workloads, by contrast, can engage 160 threads and 336 MB of shared L3, which is the clearest performance signal in the data. The Xeon 6781P is therefore best understood as a multi-thread-first processor with enough single-thread frequency headroom to support general server tasks without a dedicated high-frequency architecture.
