AMD EPYC Embedded 8224P vs AMD Ryzen 7 PRO 9755X3D Comparison

The AMD EPYC Embedded 8224P and AMD Ryzen 7 PRO 9755X3D are both 95th-percentile performers, but they achieve that status through entirely different strategies. The EPYC is a 24-core throughput monster with a 160W TDP, while the Ryzen is an 8-core, high-frequency part with a 120W TDP. In head-to-head testing, the EPYC wins 8 of 11 benchmark categories, but the Ryzen dominates the single-threaded tests, making the choice between them a clear-cut decision based on workload type.

Head-to-Head Benchmarks

The data shows a decisive victory for the EPYC Embedded 8224P in multi-threaded and parallel workloads. Its most dominant performance comes in data encryption, where it scores 43,619 compared to the Ryzen's 22,632, a massive 92.7% advantage. Random string sorting shows a similar gap, with the EPYC scoring 85,505 versus 49,050, a 74.3% lead. Integer math follows the same pattern, with the EPYC's 193,256 score outpacing the Ryzen's 119,404 by 61.9%. These results indicate that any task relying on heavy data processing or cryptographic operations will see substantial benefits from the EPYC.

The EPYC also wins decisively in floating-point math, scoring 120,066 against the Ryzen's 80,284, a 49.6% margin. The gap narrows in data compression, where the EPYC scores 681,754 against 469,207, a 45.3% lead. Even in the PassMark multithread score, which aggregates many workloads, the EPYC maintains a solid 20.8% advantage (48,873 vs. 40,474). Extended instructions favor the EPYC by 19.9% (46,091 vs. 38,436). The physics test is the closest race, with the EPYC edging out a 1.3% win (4,110 vs. 4,056), suggesting that even in more balanced tests, the core-count advantage provides a slight edge.

However, the Ryzen 7 PRO 9755X3D claims the most critical victory for single-threaded performance. It scores 4,443 in both the PassMark single-thread and singlethread tests, versus the EPYC's 2,357. That is a 47% advantage for the Ryzen, a staggering margin that reflects its much higher clock speeds. The Ryzen also wins the find prime numbers test, scoring 451 against the EPYC's 286, a 36.6% advantage. This indicates that the Ryzen's architectural efficiency and clock speed are far superior for latency-sensitive, branch-heavy workloads.

Architecture Differences

The two processors come from different design philosophies. The EPYC Embedded 8224P is based on the Zen 4c architecture, codenamed Siena, and is part of the EPYC 8004 series. It is built on a 5 nm process at TSMC, with a die size of 2x 73 mm² and 17,750 million transistors. The Ryzen 7 PRO 9755X3D uses the newer Zen 5 architecture, codenamed Granite Ridge, from the 9000 series, manufactured on a 4 nm process with a die size of 70.6 mm² and 8,315 million transistors.

Core counts differ dramatically: the EPYC has 24 cores and 48 threads, while the Ryzen has 8 cores and 16 threads. This 3x core advantage is the primary driver of the EPYC's multi-threaded wins. Clock speeds are inverted: the EPYC has a base clock of 2.55 GHz and a boost clock of 3.00 GHz, while the Ryzen runs at 4.70 GHz base and 5.20 GHz boost. The Ryzen's clocks are roughly 85% higher at base and 73% higher at boost, explaining its single-thread dominance.

Cache configurations also differ significantly. The EPYC has 64 KB of L1 per core, 1 MB of L2 per core, and 64 MB of shared L3. The Ryzen has 80 KB of L1 per core, 1 MB of L2 per core, and a larger 96 MB of shared L3. The Ryzen's larger L3 cache likely contributes to its efficiency in single-threaded tasks. The EPYC supports six-channel memory with a bandwidth of 230.4 GB/s, while the Ryzen is dual-channel with 89.6 GB/s. Both support DDR5 and ECC memory. PCIe lanes also diverge: the EPYC offers 96 Gen 5 lanes, while the Ryzen provides 24 Gen 5 lanes.

Where Each One Wins

The EPYC Embedded 8224P is the clear winner for server and workstation workloads that scale with core count and memory bandwidth. Its 20.8% lead in multithread score, combined with a 61.9% win in integer math and a 92.7% win in encryption, makes it the obvious choice for database servers, virtualization hosts, or scientific computing that uses parallel processing. The six-channel memory bus with 230.4 GB/s bandwidth ensures that data-heavy applications are not starved for memory throughput. The 96 PCIe Gen 5 lanes also make it suitable for systems with many high-speed expansion cards or NVMe storage devices.

The Ryzen 7 PRO 9755X3D wins in single-threaded performance, as shown by its 47% lead in the PassMark single-thread test. This makes it the better option for applications that rely on low-latency, high-frequency execution, such as real-time analytics, financial modeling, or legacy software that is not well-parallelized. Its 36.6% win in find prime numbers suggests it excels in workloads that involve heavy branching and integer recursion. The Ryzen's larger 96 MB L3 cache also benefits workloads that fit within that cache, reducing memory access latency.

The Verdict

Choose the AMD EPYC Embedded 8224P if your workloads are parallel and benefit from high core counts and massive memory bandwidth. The data shows it is 45.3% faster in data compression and 61.9% faster in integer math, making it ideal for server-side processing, data encryption, and multi-tenant environments. The 20.8% multithread lead and 49.6% floating-point advantage are decisive for scientific computing or rendering tasks that scale across cores. Its 96 PCIe Gen 5 lanes and six-channel memory architecture are designed for system expansion and data throughput.

Choose the AMD Ryzen 7 PRO 9755X3D if single-threaded latency is the priority. Its 47% advantage in the PassMark single-thread test is the largest margin in any benchmark category, and its 36.6% win in find prime numbers shows strength in branch-intensive code. The higher 5.20 GHz boost clock and larger 96 MB L3 cache make it the better fit for real-time processing, desktop-class workloads, or applications that cannot use more than 8 cores effectively. The lower 120W TDP also makes it easier to cool in standard workstation chassis. The verdict is straightforward: the EPYC wins on throughput, the Ryzen wins on responsiveness.
