Intel Xeon 6325P

Name: Intel Xeon 6325P
Brand: Intel
SKU: 6955

Manufacturer: Intel

The Intel Xeon 6325P is an enterprise-class processor designed for workloads that demand reliable, sustained performance within a controlled power envelope. Running four cores at a base frequency of 3.5 GHz, it carries a 55W Thermal Design Power rating, making it a measured choice for dense or thermally constrained server deployments. It supports 64-bit operation and includes hardware-level security features such as the NX bit, alongside a broad instruction set covering AVX2, AES, FMA3, and related extensions.

On the memory side, the Xeon 6325P supports DDR5 with speeds up to 4800 MHz across two channels, with a maximum addressable capacity of 128 GB and full ECC support — a standard requirement in enterprise environments where data integrity matters. Cache is organized across 320 KB of L1, 8 MB of L2 at 2 MB per core, and 12 MB of L3 at 3 MB per core. The processor uses Turbo Boost 2.0 to reach 5.2 GHz under load, and its PassMark score of 16,045 reflects its multi-threaded capability, complemented by a single-core result of 4,283. PCIe 5.0 connectivity and a 16 GT/s bus transfer rate round out its platform-level specifications.

Pros

Supports DDR5 memory at speeds up to 4800 MHz, with ECC support ensuring data integrity in server environments
PCIe 5.0 compatibility enables high-bandwidth connectivity for enterprise hardware
A 55W TDP keeps power consumption relatively contained for a server-class processor
Turbo Boost 2.0 allows the processor to scale up to 5.2 GHz from a 3.5 GHz base when workloads demand it
A broad instruction set including AVX2, AES, and FMA3 covers vectorized computing and hardware-accelerated cryptography
NX bit support provides a hardware-level layer of memory protection against certain code execution exploits

Cons

Limited to 4 cores and 8 threads, which may restrict throughput in heavily parallelized server workloads
No integrated graphics, requiring a separate graphics solution in any deployment
Maximum memory capacity of 128 GB across only 2 channels may be limiting in memory-intensive enterprise configurations
The clock multiplier is locked, offering no headroom for frequency adjustment
L3 cache of 12 MB total is relatively modest for an enterprise processor handling large datasets

Who is this for?

This processor is well-suited for enterprise server and workstation deployments where data integrity is non-negotiable, thanks to its ECC memory support and DDR5 compatibility at up to 4800 MHz. Its 55W TDP makes it a practical fit for thermally constrained or power-conscious server builds, such as compact rack units or edge computing nodes where heat and energy draw need to be managed carefully. The inclusion of PCIe 5.0, hardware AES acceleration, and the NX bit also makes it a reasonable choice for security-sensitive or network-facing workloads that benefit from fast I/O throughput and built-in memory protection.

Who is this NOT for?

With only 4 cores and 8 threads, this processor is not well-matched for heavily parallelized server workloads such as large-scale virtualization or high-concurrency database engines that benefit from significantly higher core counts. The absence of integrated graphics means it is entirely unsuitable for any deployment requiring display output without a discrete GPU, adding complexity to minimal or headless setups that still need occasional visual access. Additionally, the 2-channel memory configuration with a 128 GB ceiling may fall short for memory-intensive enterprise applications such as in-memory analytics or large dataset processing that routinely demand greater bandwidth and capacity.

General info:

The Intel Xeon 6325P operates across four cores at a base speed of 3.5 GHz each, supporting 8 threads in total through multithreading, and can reach a turbo clock speed of 5.2 GHz via Turbo Boost version 2. The clock multiplier is set at 35 and is locked, meaning the processor does not support an unlocked multiplier. Cache is distributed across three levels: 320 KB of L1, 8 MB of L2 at 2 MB per core, and 12 MB of L3 cache at 3 MB per core, providing a structured hierarchy to help reduce memory latency during demanding workloads.

Memory:

bus transfer rate	16 GT/s

The Intel Xeon 6325P uses DDR5 memory, with a maximum supported speed of 4800 MHz and a bus transfer rate of 16 GT/s. It operates across two memory channels and can address up to 128 GB of RAM in total. The processor also supports ECC memory, which enables hardware-level detection and correction of memory errors — a standard requirement in server and enterprise environments where data reliability is a priority.

Features:

Has NX bit	✓

The Intel Xeon 6325P supports multithreading, allowing each physical core to handle more than one thread simultaneously. It includes the NX bit, a hardware security feature that helps prevent certain classes of malicious code from executing in memory regions marked as non-executable. On the instruction set side, the processor supports a broad range of extensions including MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, and SSE 4.2, covering acceleration for floating-point math, cryptographic operations, and vectorized data processing.

Benchmarks:

PassMark result	16045
PassMark result (single)	4283

In PassMark testing, the Intel Xeon 6325P achieves a multi-threaded score of 16,045, reflecting its capacity across all cores and threads under concurrent workloads. Its single-core PassMark result of 4,283 indicates the per-core processing throughput measured in isolation, which is a relevant figure for workloads that depend heavily on single-threaded execution.

Final Verdict

The Intel Xeon 6325P is a focused enterprise processor that trades raw core density for a controlled power footprint and a well-rounded feature set. Its DDR5 support with ECC, PCIe 5.0 connectivity, and hardware-level security features make it a dependable choice for server environments where reliability, data integrity, and I/O throughput matter more than maximum parallelism. The locked multiplier and modest core count mean it is not intended for workloads that scale aggressively with thread count or demand extensive memory bandwidth, but within its intended scope — compact, security-conscious, or thermally managed enterprise deployments — it delivers a coherent and well-specified platform. Organizations building around stable, single-threaded to lightly multi-threaded server workloads will find it a technically sound fit.
