Intel Xeon 6766E

The Intel Xeon 6766E is a 144-core, 144-thread server processor built for Intel Socket 4710. It belongs to the Sierra Forest architecture and the Xeon 6 (Sierra Forest-SP) generation, fabricated on Intel's 5 nm process with a 578 mm² die. The part is identified as part number SRPFW, is classified in the Server/Workstation market segment, and has a production status of Active. It was released on 2024-06-02, with a base clock of 1900.00 MHz and a boost clock of 2.70 GHz, alongside a 250 W TDP. The cache hierarchy consists of 96 KB of L1 per core, 4 MB of L2 per module, and 108 MB of shared L3. Memory support includes DDR5 across an eight-channel bus, 409.6 GB/s of memory bandwidth, and ECC capability. The processor also lists Gen 5 PCIe with 88 lanes (CPU only). The benchmark portion of the record is empty: the average benchmark score is 0, the nearest rivals list is empty, and the percentile against all CPUs is 50.

Benchmark Performance

The benchmark data for the Intel Xeon 6766E is not populated. The `benchmarks` array is empty, the average benchmark score is 0, and there are no nearest rivals with scores or deltaPct values. This means no measured performance numbers exist in the database entry to analyze or compare. The only comparative figure present is `percentileVsAllCpus: 50`, which places the entry at the midpoint of the database’s all-CPU percentile distribution. That percentile is a database placement, not a tested score, and it should not be conflated with a specific benchmark result.

Because there are no benchmark scores, the specification sheet becomes the only performance signal. The processor lists 144 cores and 144 threads, which is a very high thread count, and 108 MB of shared L3 cache. The memory subsystem lists eight-channel DDR5 support and 409.6 GB/s of bandwidth, both of which are platform-level characteristics associated with feeding many cores. The base clock of 1900.00 MHz and boost clock of 2.70 GHz are the only frequency figures in the data. The 250 W TDP defines the power envelope. The record does not provide any single-thread score, multi-thread score, or workload-specific result.

Without measured scores, no direct percentage comparisons can be made against other processors. The average benchmark score of 0 does not represent a tested zero; it reflects the absence of benchmark entries in the database. The 50th percentile placement against all CPUs is a neutral midpoint, and it carries no further ranking detail because no nearest rivals are listed. A 144-core part with 108 MB of shared L3 and an eight-channel DDR5 memory path is likely aimed at throughput-heavy server workloads, but that inference is based on the listed specifications, not on benchmark outcomes. The data simply cannot confirm how this processor performs relative to any other model.

Single-Thread vs Multi-Thread Behavior

The Intel Xeon 6766E entry contains no separate single-thread or multi-thread benchmark scores. As a result, the split between those two behaviors cannot be quantified from the database record. The specification data does show a configuration with 144 cores and exactly 144 threads, meaning the record does not list any extra logical threads beyond the physical core count. For workloads that use many concurrent threads, the core count and thread count are the dominant listed attributes.

The boost clock of 2.70 GHz is the highest frequency listed, while the base clock is 1900.00 MHz. These are the only clock figures available, and the data does not state whether 2.70 GHz applies to one core, several cores, or all cores. For lightly threaded workloads, clock speed and cache access usually matter more than raw core count, but there is no tested single-thread score in this entry to evaluate that behavior. For heavily threaded workloads, 144 threads, 108 MB of shared L3, and 409.6 GB/s of memory bandwidth are the parameters that define the design’s potential. The L1 cache is listed at 96 KB per core, and the L2 cache is listed at 4 MB per module. The memory bus is eight-channel DDR5, which provides a wide data path for many cores operating simultaneously.

The equal core and thread counts indicate that each thread corresponds to a dedicated core, so there is no additional simultaneous multithreading count in the record. That configuration benefits workloads written to scale across many physical cores. In contrast, the data offers no evidence for how the processor behaves on a single-threaded task. The only frequency-specific fact is the range between 1900.00 MHz base and 2.70 GHz boost. Without per-thread scores, any statement about single-thread responsiveness would be speculation. The multi-thread side is better represented by structural specifications: 144 threads, 108 MB shared L3, eight-channel memory, and 409.6 GB/s of memory bandwidth.

Who Should Consider It

The Intel Xeon 6766E is listed for the Server/Workstation market segment. The specification sheet shows 144 cores, 144 threads, 108 MB of shared L3, eight-channel DDR5, and 409.6 GB/s of memory bandwidth. Those are characteristics associated with workloads that can use many concurrent execution contexts and move large amounts of data. For workloads that scale across all 144 threads, the thread count is the primary listed asset. For workloads with large shared working sets, 108 MB of L3 is the relevant cache figure. For workloads that are memory-bandwidth-bound, 409.6 GB/s and the eight-channel memory bus define the platform’s data throughput.

ECC memory support is listed, which points toward reliability-sensitive server environments. Gen 5 PCIe with 88 lanes (CPU only) supports many attached devices, making the processor appropriate for systems with multiple accelerators, storage controllers, or network interfaces. The 250 W TDP indicates a high-power part requiring substantial cooling and power delivery. The record contains no gaming scores, so a gaming recommendation cannot be grounded in benchmark data. The record also contains no creation-application scores, so any creation workload conclusion would have to rely entirely on the broad core-count and memory-bandwidth specifications. Lightly threaded office workloads are typically more dependent on per-core frequency and latency; the data here has no measured office or single-thread result to support that use case.

The most defensible recommendation is for server workloads that can use 144 threads and 409.6 GB/s of memory bandwidth. The architecture name Sierra Forest and the Xeon 6 (Sierra Forest-SP) generation label further position it in Intel’s server lineup. The locked multiplier, indicated by `multiplierUnlocked: false`, means the processor is not intended for user overclocking. The absence of benchmark results prevents a more specific workload-by-workload ranking. Users who need measured performance data will have to wait until benchmark entries are added to the database.

How It Compares

The database entry for the Intel Xeon 6766E lists no nearest rivals. The `nearestRivals` array is empty, so there are no rival names, no score deltas, and no relative performance positions to summarize. The only comparative number in the entry is the 50th percentile among all CPUs, and the average benchmark score is 0. Without rival entries, the database cannot show how this processor stacks up against any specific competing model. The product remains Active, uses Intel Socket 4710, and has a locked multiplier. Its release date is 2024-06-02. Until benchmark records are added, no competitive comparison can be derived from the data on file.
