AMD Epyc 4364P

Manufacturer: AMD

The AMD Epyc 4364P is a server-oriented processor designed for the enterprise CPU market, combining a compact 8-core layout with a 5.4 GHz turbo clock speed and a 105W thermal design power envelope. Built on a 5 nm semiconductor process, it supports 64-bit workloads and offers PCIe 5.0 connectivity, making it a technically current option for single-socket server deployments.

On the memory side, the Epyc 4364P supports DDR5 at up to 5200 MHz across two channels, with a maximum capacity of 192 GB and a peak bandwidth of 83.2 GB/s. ECC memory support is included, which is standard for enterprise reliability requirements. The processor provides 512 KB of L1 cache, 8 MB of L2 cache, and 32 MB of L3 cache, while its instruction set coverage includes AVX2, AES, FMA3, and SSE 4.2, among others. In benchmarking, it scores 34811 in the PassMark multi-threaded test and 3661 in the single-threaded result.

Pros
  • ECC memory support adds a layer of data integrity protection suited to server and enterprise workloads
  • DDR5 support with a maximum speed of 5200 MHz and 83.2 GB/s bandwidth provides a fast memory subsystem for a dual-channel configuration
  • A turbo clock speed of 5.4 GHz gives the processor meaningful headroom above its 4.5 GHz base frequency
  • 32 MB of L3 cache spread across 8 cores helps reduce memory latency for data-intensive tasks
  • PCIe 5.0 support enables compatibility with current-generation expansion cards and storage devices
  • Built on a 5 nm process node, keeping the 105W TDP relatively contained for an enterprise-class CPU
Cons
  • No integrated graphics means an additional discrete component is required for any display output
  • The memory controller supports only two channels, which limits total memory bandwidth scaling compared to higher-channel configurations
  • The clock multiplier is locked, removing any possibility of frequency tuning through multiplier adjustment
  • With a maximum supported memory capacity of 192 GB across two channels, large in-memory workloads may be constrained relative to higher-channel enterprise platforms
Who is this for?

The AMD Epyc 4364P is well matched to single-socket enterprise server deployments where a balance of per-core speed and thread count matters — its 5.4 GHz turbo frequency and 16 threads make it a reasonable fit for workloads that rely on both single-threaded responsiveness and moderate parallelism. The inclusion of ECC memory support and DDR5 at up to 5200 MHz makes it appropriate for environments where data integrity is critical, such as database servers, virtualization hosts, or business-critical applications. Its PCIe 5.0 interface also suits deployments requiring fast NVMe storage or high-throughput networking cards.

Who is this NOT for?

This processor is not well suited to workloads demanding very high core counts or extensive memory scaling, as its 8-core design and dual-channel memory controller cap both parallel throughput and total addressable memory at 192 GB. Users requiring integrated graphics — such as those building compact all-in-one server appliances or systems without a discrete GPU — will find this processor inadequate, as it provides no on-chip display output. It is also a poor fit for scenarios that benefit from overclocking or frequency customization, given that the clock multiplier is locked and cannot be adjusted.

General info:

Thermal Design Power (TDP) 105W
semiconductor size 5 nm
PCI Express (PCIe) version 5
Supports 64-bit ✓
Has integrated graphics ✕

The AMD Epyc 4364P carries a Thermal Design Power (TDP) of 105W and is fabricated on a 5 nm semiconductor process, reflecting a relatively compact manufacturing node for this class of enterprise processor. It supports the PCIe 5.0 interface standard and is fully 64-bit capable. The processor does not include integrated graphics, so a discrete GPU or external display adapter is required for any visual output.

Performance:

CPU speed 8 x 4.5 GHz
CPU threads 16 threads
turbo clock speed 5.4GHz
L3 cache 32 MB
L1 cache 512 KB
L2 cache 8 MB
L2 core 1 MB/core
clock multiplier 45
Has an unlocked multiplier ✕
L3 core 4 MB/core

The AMD Epyc 4364P runs 8 cores at a base clock speed of 4.5 GHz each, with a turbo clock speed reaching 5.4 GHz, and exposes 16 threads in total. The clock multiplier is set at 45 and the multiplier is locked, meaning frequency adjustments through multiplier tuning are not supported. Cache is distributed across three levels: 512 KB of L1, 8 MB of L2 at 1 MB per core, and 32 MB of L3 at 4 MB per core, providing a tiered memory hierarchy intended to reduce latency on frequently accessed data.

Memory:

Supports ECC memory ✓
maximum memory bandwidth 83.2 GB/s
DDR memory version 5
RAM speed (max) 5200 MHz
maximum memory amount 192GB
memory channels 2

The AMD Epyc 4364P uses a dual-channel DDR5 memory configuration, supporting speeds of up to 5200 MHz and a maximum installed capacity of 192 GB. Peak memory bandwidth reaches 83.2 GB/s, which reflects the throughput available across both channels at full speed. The processor also supports ECC memory, allowing the system to detect and correct single-bit memory errors — a standard requirement in enterprise and server environments where data integrity is a priority.

Features:

instruction sets MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, SSE 4.2
Has NX bit ✓

The AMD Epyc 4364P supports a broad set of instruction extensions, including AVX2, FMA3, and AES, alongside MMX, F16C, AVX, SSE 4.1, and SSE 4.2, covering a range of workloads from floating-point and vector operations to hardware-accelerated encryption. The processor also features the NX bit, a hardware-level security mechanism that helps prevent certain classes of malicious code execution by marking memory regions as non-executable.

Benchmarks:

PassMark result 34811
PassMark result (single) 3661

In PassMark testing, the AMD Epyc 4364P achieves a multi-threaded score of 34811, reflecting its aggregate throughput across all cores and threads. Its single-threaded PassMark result of 3661 indicates the per-core performance level as measured by that benchmark.

Final Verdict

The AMD Epyc 4364P positions itself as a focused single-socket enterprise processor, bringing together a 5 nm build, PCIe 5.0 connectivity, and a 5.4 GHz turbo clock speed within a 105W thermal envelope that remains manageable for server environments. ECC memory support and DDR5 compatibility reinforce its suitability for reliability-sensitive deployments such as virtualization and database hosting. That said, its 8-core design and dual-channel memory architecture mean it is best matched to workloads that do not demand extreme parallelism or very large memory footprints. For organizations seeking a capable, power-efficient single-socket server CPU with strong per-core frequency and current-generation platform support, the Epyc 4364P is a technically coherent choice within its intended segment.
