AMD EPYC Embedded 8224P vs AMD Ryzen 7 PRO 9745 Comparison

The AMD EPYC Embedded 8224P and AMD Ryzen 7 PRO 9745 are both active, server-class processors from AMD, but they are engineered for entirely different corners of the data center. The EPYC is a 24-core Zen 4c part built for dense, multi-threaded throughput on Socket SP6, while the Ryzen 7 PRO is an 8-core Zen 5 chip on Socket AM5 aimed at high-frequency, single-thread response. Benchmark results show a complete split in workload dominance, with the EPYC winning 9 of 11 head-to-head tests and the Ryzen taking the remaining 2.

Head-to-Head Benchmarks

The most lopsided result in the entire comparison is in the PassMark physics test. The EPYC Embedded 8224P scores 4110, which is a staggering 102.9% higher than the Ryzen 7 PRO 9745’s 2026. This is the largest delta of any test, indicating that the EPYC’s massive core count provides an overwhelming advantage in simulation-style physics calculations. No other test comes close to this margin, making it the definitive proof of the EPYC’s multi-threaded dominance.

Beyond physics, the EPYC’s lead in integer math is nearly as convincing. It posts a score of 193256 against the Ryzen’s 124167, a 55.6% advantage. This is a core workload for general server tasks, and the data shows the EPYC handling it with 24 cores and 48 threads working in parallel. Similarly, in find prime numbers, the EPYC scores 286 versus 188, a 52.1% win. The pattern is clear: the more threads a test can use, the more the EPYC pulls ahead.

The data encryption test shows the EPYC’s advantage at 90.9%, with scores of 43619 against 22848. This is a significant gap that would matter for any workload involving secure data handling. The EPYC also wins data compression by 49.1% (681754 vs 457211), floating point math by 45.6% (120066 vs 82461), and random string sorting by 73.7% (85505 vs 49219). In every one of these multi-threaded tests, the EPYC’s 48 threads simply overwhelm the Ryzen’s 16. The extended instructions test is closer, but the EPYC still wins by 25.2% (46091 vs 36800), and the overall multithread score favors the EPYC by 27.9% (48873 vs 38201).

The Ryzen 7 PRO 9745’s only victories come in the single-thread tests, and they are decisive. In PassMark single thread, the Ryzen scores 4624 against the EPYC’s 2357, a 49% advantage in the EPYC’s favor when reversed. This is the mirror image of the physics test. The Ryzen’s Zen 5 architecture, with a boost clock of 5.40 GHz, utterly outclasses the EPYC’s 3.00 GHz boost in latency-sensitive, single-threaded work. The Ryzen wins both the single thread and singlethread benchmarks by the same margin, confirming that its high-frequency design is the correct choice for lightly-threaded tasks.

The Verdict

The data dictates a strict use-case split. If the workload is heavily parallel, the AMD EPYC Embedded 8224P is the only rational choice. Its wins in 9 of 11 benchmarks, including a 102.9% lead in physics and a 90.9% lead in encryption, make it the clear performance leader for multi-threaded throughput. The Ryzen 7 PRO 9745 cannot compete in these areas, and no amount of single-thread speed can close a 55.6% gap in integer math.

For applications that are primarily single-threaded, the AMD Ryzen 7 PRO 9745 is the superior part. Its 4624 single-thread score is nearly double the EPYC’s 2357. This makes it ideal for tasks like database queries, legacy application serving, or any software that has not been optimized for parallel execution. The EPYC’s lower clock speed, capped at 3.00 GHz, is a severe handicap in these scenarios.

There is no overall winner here. There are two distinct winners for two distinct jobs. The EPYC is a throughput monster; the Ryzen is a latency specialist. Choosing the wrong one means leaving significant performance on the table. The EPYC’s average benchmark score of 76492 versus the Ryzen’s 74761 is a negligible 2.3% difference, but that average hides the massive divergence in individual tests. The percentile ranking for both is 95 against all CPUs, but that is a measure of overall capability, not suitability for a given task.

Where Each One Wins

The AMD EPYC Embedded 8224P wins every test that can scale across its 24 cores. This includes data compression, where it leads by 49.1%, and data encryption, where it leads by 90.9%. It also dominates floating point math by 45.6% and integer math by 55.6%. These are the building blocks of scientific computing, financial modeling, and large-scale data processing. The physics test, with its 102.9% lead, makes it the clear pick for any form of simulation or rendering that leverages multi-threading. The random string sorting win by 73.7% also points to strengths in data indexing and sorting tasks.

The AMD Ryzen 7 PRO 9745 wins exclusively in single-threaded performance. Its 4624 score in PassMark single thread is a 49% improvement over the EPYC. This makes it the better choice for any workload that is bottlenecked by a single core. This includes many real-time applications, interactive workloads, and software that relies on high clock speeds rather than core count. The Ryzen’s 5.40 GHz boost clock versus the EPYC’s 3.00 GHz is the key differentiator. For a server handling a few demanding requests sequentially, the Ryzen will feel faster.

The EPYC’s multithread score of 48873 versus the Ryzen’s 38201 shows that even in a mixed workload, the EPYC holds a 27.9% lead. The Ryzen’s only hope is to keep every task on as few threads as possible. If your application can fully utilize the EPYC’s 48 threads, the data shows it will win nearly every time. If your application is stubbornly single-threaded, the Ryzen is the only part that makes sense.

Architecture Differences

The two processors are built on different Zen architectures and process nodes. The EPYC Embedded 8224P uses Zen 4c, the dense variant of Zen 4, on a 5 nm TSMC process. The Ryzen 7 PRO 9745 uses Zen 5 on a 4 nm TSMC process. This node difference contributes to the Ryzen’s higher clock speeds. The EPYC has a transistor count of 17,750 million across a 2x 73 mm² die design, while the Ryzen has 8,315 million transistors on a single 70.6 mm² die.

Cache configurations differ significantly. The EPYC has 64 KB of L1 and 1 MB of L2 per core, with a large 64 MB shared L3 cache. The Ryzen has 80 KB of L1 and 1 MB of L2 per core, but only 32 MB of shared L3. The EPYC’s larger L3 cache is a direct result of its server-focused design, providing more data storage for its many cores. The EPYC also lacks integrated graphics, while the Ryzen 7 PRO 9745 includes Radeon Graphics. Both support ECC memory, but the EPYC’s six-channel memory controller versus the Ryzen’s dual-channel is a major architectural difference.

The EPYC is built on the Zen 4c (Siena) codename, while the Ryzen is on Granite Ridge. The EPYC’s generation is listed as EPYC (Zen 4c (Siena)), and the Ryzen’s is Ryzen 7 (Zen 5 (Granite Ridge)). The EPYC is part of the EPYC 8004 series, and the Ryzen is part of the 9000 series. These are fundamentally different product lines with different design goals.

Specification Differences

The core and thread counts are the most obvious specification difference: the EPYC has 24 cores and 48 threads, while the Ryzen has 8 cores and 16 threads. Base clocks also diverge, with the EPYC at 2.55 GHz and the Ryzen at 3.80 GHz. Boost clocks show an even larger gap, with the EPYC at 3.00 GHz and the Ryzen at 5.40 GHz.

The thermal design power (TDP) is a major differentiator. The EPYC is rated at 160 W, while the Ryzen is rated at 65 W. This reflects the EPYC’s need for power to drive its 24 cores. The sockets are incompatible: the EPYC uses AMD Socket SP6, and the Ryzen uses AMD Socket AM5. PCIe lane counts also differ, with the EPYC offering 96 Gen 5 lanes (CPU only) versus the Ryzen’s 24 Gen 5 lanes (CPU only).

Memory support shows a clear separation. The EPYC supports six-channel DDR5 with a bandwidth of 230.4 GB/s. The Ryzen supports dual-channel DDR5 with a bandwidth of 89.6 GB/s. Both support ECC memory. The EPYC has no integrated graphics, while the Ryzen includes Radeon Graphics. The release dates differ, with the EPYC released on 2023-09-17 and the Ryzen on 2025-09-15. The EPYC’s part number is 100-000001418, and the Ryzen’s is 100-000001408. Neither processor has an unlocked multiplier.
