AMD EPYC 8224P

The AMD EPYC 8224P is a 24-core, 48-thread server processor built on the Zen 4c architecture, codenamed Siena, and manufactured on a 5 nm process at TSMC. It occupies a specific niche in AMD’s EPYC 8004 series lineup, targeting single-socket platforms where power efficiency and density matter more than raw top-end performance. With a launch MSRP of $855, the chip sits in the mid-range of the SP6 platform, offering a balanced mix of compute throughput, memory bandwidth, and PCIe connectivity for a variety of server and workstation workloads.

Benchmark Performance

The benchmark data positions the EPYC 8224P as a remarkably consistent performer relative to its closest competitors. Its average benchmark score of 75,582 places it at the 97th percentile of all CPUs tracked, indicating that despite its modest clock speeds, it outperforms the vast majority of processors on the market. The nearest rival, the Intel Core Ultra 9 285, scores 75,400, which puts the EPYC 8224P just 0.2% ahead—a statistical tie in practical terms. Similarly, the AMD Ryzen AI Max+ 395 scores 75,265, meaning the EPYC 8224P leads by 0.4%. These margins are negligible, suggesting that in aggregate multi-threaded workloads, the server chip trades blows with high-end consumer and mobile parts.

However, the picture shifts when comparing against the other two rivals. The Intel Core Ultra 9 275HX scores 76,024, which is 0.6% higher than the EPYC 8224P, while the AMD EPYC 4545P scores 76,433, a 1.1% advantage. These deltas are small in absolute terms—roughly 400 to 850 points on a multi-thousand-point scale—but they establish a clear hierarchy: the EPYC 8224P is not the fastest in its immediate peer group, yet it is close enough that workload-specific factors will determine the winner.

Digging into specific Cinebench results, the multi-core scores are impressive for a 160W processor. The Cinebench R23 multi-core score of 38,607 demonstrates strong scaling across the 24 cores, while the R20 score of 16,214 and R15 score of 3,891 follow the expected progression. In single-core tests, the R23 single-core score of 5,450 and R20 single-core of 2,289 show that the 2.55 GHz base and 3.00 GHz boost clocks are adequate but not exceptional—this is a chip designed for throughput rather than latency-sensitive single-thread workloads.

Passmark results reinforce the multi-threaded focus. The multithread score of 45,421 is solid, but the individual sub-tests reveal specific strengths. Integer math scores 185,556, floating-point math 104,698, and extended instructions 43,614, all suggesting robust compute capabilities. Data compression scores 702,065, which is notably high and indicates strong memory subsystem performance, while data encryption at 46,742 and find prime numbers at 206 show more moderate results. The random string sorting score of 81,674 further confirms that the chip handles memory-intensive operations well.

Power and Thermals

The EPYC 8224P carries a TDP class of 160W, which is a moderate value for a server processor with 24 cores. This rating suggests that the chip is designed for dense, single-socket servers where cooling infrastructure may be limited. The 5 nm process node and 2x 73 mm² die size, containing 17,750 million transistors, indicate that AMD has prioritized power efficiency in this design. The architecture, Zen 4c, is specifically optimized for high core density with lower clock speeds, which aligns with the 160W TDP.

From a cooling perspective, a 160W TDP typically requires a capable air cooler or a low-profile liquid cooler in a server chassis. The data does not specify thermal performance under load, but the TDP class implies that standard server cooling solutions—such as 1U or 2U heatsinks with high-static-pressure fans—should be sufficient. In a workstation context, a mid-range tower cooler would likely handle the thermal load without issue. The lack of an unlocked multiplier means users cannot overclock to increase performance, which also keeps thermal requirements predictable.

The power characteristics matter in real-world deployment. For a 24-core processor, 160W is relatively modest compared to higher-end EPYC parts that push beyond 200W or 300W. This makes the 8224P suitable for environments where power density is a concern, such as colocation facilities or edge computing setups. The trade-off is lower maximum clock speeds, which we see in the 3.00 GHz boost, but the efficiency gains are evident in the benchmark scores relative to the TDP class.

Single-Thread vs Multi-Thread Behavior

The split between single-thread and multi-thread performance is stark and defines the EPYC 8224P’s personality. In Cinebench R23, the multi-core score of 38,607 is roughly 7.1 times the single-core score of 5,450, indicating excellent scaling across the 24 cores. This scaling factor is near-ideal for a processor with 24 physical cores and 48 threads, suggesting that the Zen 4c cores communicate efficiently and the memory subsystem does not become a bottleneck in heavily threaded workloads.

However, the single-thread performance is a clear weakness. The Cinebench R15 single-core score of 549 and R20 score of 2,289 place the chip in the range of mid-tier consumer processors from a few generations ago. The Passmark single-thread score of 2,339 confirms this trend. For workloads that rely on a single core—such as legacy applications, certain database queries, or lightly threaded games—the 8224P will not impress. The 3.00 GHz boost clock is simply not high enough to compete with modern desktop chips that boost above 5 GHz.

This behavior implies that the EPYC 8224P is best suited for workloads that can utilize all cores simultaneously. Virtualization, containerized microservices, batch processing, and scientific simulations are ideal candidates. Conversely, tasks like interactive development, single-threaded scripting, or real-time rendering that depend on single-core speed will see lackluster performance. The data suggests that users should not expect snappy responsiveness in single-threaded applications, but rather sustained throughput in parallel workloads.

Platform and Compatibility

The EPYC 8224P uses the AMD Socket SP6 platform, which is a departure from the larger SP5 socket used by higher-end EPYC 9004 series processors. The SP6 socket is designed specifically for the EPYC 8004 series, targeting single-socket servers and workstations with a more compact footprint. The chip supports DDR5 memory with a six-channel memory bus, providing a memory bandwidth of 230.4 GB/s. ECC memory is supported, which is critical for server reliability and data integrity.

PCIe connectivity is a major strength: the processor offers Gen 5 with 96 lanes available from the CPU. This is an enormous amount of I/O bandwidth, suitable for high-speed NVMe storage arrays, multiple GPUs, or network interface cards. For a server platform, 96 PCIe Gen 5 lanes is a differentiating feature that few rivals at this price point can match. The combination of six-channel DDR5 and 96 PCIe lanes gives the 8224P exceptional I/O capability for its class.

The upgrade path is limited by the SP6 platform’s lifecycle. Since the EPYC 8004 series is a distinct generation, future upgrades would require a new motherboard if AMD moves to a different socket. However, within the current generation, users can choose from other SP6 processors with different core counts and TDPs, allowing for scalability without a platform change. The production status is listed as active, and the release date of September 17, 2023, means the platform is still relatively young, so there is likely headroom for future SP6 processors.

How It Compares

Against the Intel Core Ultra 9 285, the EPYC 8224P holds a razor-thin 0.2% lead in average benchmark score. This is effectively a tie, but the comparison is misleading because the Ultra 9 285 is a consumer desktop processor, while the EPYC 8224P is a server chip. In multi-threaded workloads, the EPYC’s 24 cores and 48 threads likely provide an advantage, but the Intel part’s higher clock speeds may win in single-threaded tasks. The 96 PCIe lanes and six-channel memory are clear server advantages that the desktop part cannot match.

The AMD Ryzen AI Max+ 395 is another consumer-oriented rival, and the EPYC 8224P leads by 0.4%. The Ryzen AI Max+ 395 is a high-end APU with integrated graphics, whereas the EPYC 8224P has no integrated graphics. In pure CPU compute, they are close, but the EPYC’s server features—ECC memory, 96 PCIe lanes, and six-channel DDR5—make it a more appropriate choice for enterprise workloads. The Ryzen part would be better for a workstation with GPU-intensive tasks, given its integrated graphics and consumer platform.

The Intel Core Ultra 9 275HX is a mobile processor, yet it outperforms the EPYC 8224P by 0.6% in average score. This is surprising given the power envelope differences—the mobile chip likely has a lower TDP, but higher boost clocks compensate. The EPYC 8224P’s advantage lies in its scalability and I/O, not raw performance. For a server, the 275HX is irrelevant, but the comparison highlights that the EPYC 8224P is not a performance leader, even against mobile parts.

The AMD EPYC 4545P is the closest server rival, and it beats the 8224P by 1.1%. The 4545P is likely a higher-clocked or higher-core-count part in the same SP6 family. The data suggests that for users willing to spend slightly more, the 4545P offers better performance. However, the 8224P’s lower TDP and potentially lower price (though not stated) might make it a better fit for power-constrained environments. The 1.1% delta is small enough that workload-specific benchmarking is necessary to choose between them.

Who Should Consider It

The EPYC 8224P is a clear choice for server administrators and workstation builders who prioritize multi-threaded throughput and I/O capacity over single-core speed. Its 24 cores and 48 threads, combined with a multi-core Cinebench R23 score of 38,607, make it ideal for virtualization hosts running many concurrent VMs, containerized workloads, or batch processing jobs that scale across cores. The 96 PCIe Gen 5 lanes are a standout feature for storage servers—users can populate numerous NVMe drives without sacrificing bandwidth. The six-channel DDR5 memory with 230.4 GB/s bandwidth ensures that memory-intensive applications like in-memory databases or data analytics will not be starved.

For content creation, the picture is mixed. The multi-threaded Passmark scores, such as integer math at 185,556 and floating-point math at 104,698, suggest that video encoding, 3D rendering, and scientific simulations will perform well. However, the single-thread score of 2,339 in Passmark means that tasks like photo editing with heavy filters or single-threaded plugins will lag. A creator who works primarily in multi-threaded renderers would find the 8224P capable, but one who relies on single-threaded tools would be better served by a higher-clock consumer processor.

Office and general productivity workloads do not align well with this chip. The low single-core performance would make everyday tasks feel sluggish compared to a modern desktop CPU, and the server platform lacks the integrated graphics that office systems typically rely on. However, for a headless server running database queries, web hosting, or backend services, the EPYC 8224P excels. Its 160W TDP makes it suitable for dense server environments where power and cooling are limited, and the active production status ensures ongoing availability. In summary, the EPYC 8224P is a specialist tool: it shines in parallel, I/O-heavy server workloads, but it is not a general-purpose processor for desktop or single-threaded tasks.
