Intel Xeon 6747P

Name: Intel Xeon 6747P
Brand: Intel
SKU: 83203

Manufacturer: Intel

The Intel Xeon 6747P is a high-core-count server processor designed for demanding enterprise workloads. Built on a 3 nm semiconductor process, it ships with 48 physical cores and 96 threads, operating at a base frequency of 2.7 GHz across all cores with a Turbo Boost 2 peak of 3.9 GHz. Its 330 W TDP reflects the scale of compute it delivers, and the absence of integrated graphics keeps the silicon focused entirely on raw processing throughput.

From a memory standpoint, the Xeon 6747P supports DDR5 across eight channels, with a maximum speed of 8000 MHz and capacity headroom up to 4000 GB, alongside ECC support suited to reliability-critical environments. The cache hierarchy is substantial, with 5376 KB of L1, 96 MB of L2 at 2 MB per core, and 288 MB of L3 cache at 6 MB per core. PCIe 5 connectivity and a 24 GT/s bus transfer rate round out the platform, while instruction set support includes AVX2, AES, FMA3, and SSE 4.2, among others. The processor scores 100,964 in PassMark multi-threaded and 3,242 in the single-threaded benchmark.

Pros

ECC memory support ensures hardware-level detection and correction of in-memory errors, making it suitable for environments where data integrity cannot be compromised
Eight DDR5 memory channels with a maximum speed of 8000 MHz allow substantial memory bandwidth for multi-threaded server workloads
Support for up to 4000 GB of total system memory accommodates extremely memory-intensive deployments without hitting capacity constraints
The 288 MB L3 cache, distributed at 6 MB per core, provides a large on-chip data buffer that helps sustain throughput across all 48 cores
PCIe 5 support enables high-bandwidth connectivity for modern storage and networking peripherals
NX bit support adds a hardware-enforced layer of memory protection relevant to security-sensitive server environments

Cons

A 330W TDP places significant demands on server cooling infrastructure and power delivery systems
No integrated graphics means a discrete solution must be present for any display output, adding a dependency in headless or remotely managed setups
The locked clock multiplier removes any ability to adjust base frequency outside of standard Turbo Boost operation
Single-threaded PassMark score of 3,242 indicates moderate per-core throughput, which may be a limiting factor for workloads that rely heavily on sequential processing

Who is this for?

This processor is well-matched to large-scale enterprise server environments that depend on sustained multi-threaded throughput. Its 48 cores, 96 threads, and 288 MB of L3 cache make it a strong fit for workloads such as virtualization, database engines, and parallel data processing, where keeping many threads active simultaneously is essential. The combination of eight-channel DDR5 memory with ECC support and up to 4000 GB capacity also makes it particularly appropriate for in-memory computing platforms and workloads where data integrity under continuous operation is non-negotiable. Environments that require PCIe 5 connectivity for high-bandwidth NVMe storage arrays or network adapters will also benefit from the platform's I/O capabilities.

Who is this NOT for?

This processor is not a practical fit for use cases that depend heavily on single-threaded responsiveness, as its single-threaded PassMark score of 3,242 reflects moderate per-core throughput rather than peak sequential speed. It is equally unsuitable for any deployment where display output is needed without an additional discrete GPU, given the complete absence of integrated graphics. Beyond that, its 330W TDP makes it impractical for space-constrained or power-sensitive installations where thermal headroom and electrical capacity are limited, such as edge computing nodes or compact rackmount configurations with restricted cooling budgets.

General info:

The Intel Xeon 6747P supports multithreading, allowing each physical core to handle two threads simultaneously for more efficient utilization under parallel workloads. It carries a broad instruction set portfolio — MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, and SSE 4.2 — covering vectorized math, hardware-accelerated encryption, and floating-point operations across a range of application types. The processor also includes NX bit support, which enables hardware-level memory protection by marking certain memory regions as non-executable, a standard feature in security-conscious server deployments.

Benchmarks:

PassMark result	100964
PassMark result (single)	3242

In PassMark testing, the Intel Xeon 6747P achieves a multi-threaded score of 100,964, reflecting the cumulative throughput delivered across its full core and thread count. Its single-threaded PassMark result of 3,242 represents the per-core performance level, which is relevant for workloads that depend on sequential execution rather than parallelism.

Final Verdict

The Intel Xeon 6747P is a purpose-built enterprise processor that makes a clear case for itself in high-density, multi-threaded server environments. Its combination of 48 cores, eight-channel DDR5 memory with ECC support, and a 288 MB L3 cache positions it firmly within demanding workloads such as virtualization, large-scale databases, and parallel compute tasks where consistent throughput across many threads matters more than peak single-core speed. The platform's thermal and power requirements, along with its dependence on a discrete GPU for any display output, mean it is suited to well-resourced data center deployments rather than general-purpose or space-constrained roles. For organizations operating within that context, the Xeon 6747P represents a technically coherent choice with the memory capacity, bandwidth, and core count to sustain enterprise-grade workloads reliably.
