AMD EPYC Embedded 8224P vs AMD Ryzen 9 9950X3D Comparison

The AMD EPYC Embedded 8224P and the AMD Ryzen 9 9950X3D represent two very different interpretations of high-end x86 performance, and the benchmark data reflects that split decisively. While both processors land in the 95th percentile of all CPUs, their average benchmark scores are nearly identical—76,492 for the EPYC and 75,779 for the Ryzen—the head-to-head results reveal a stark division of labor that goes far beyond the aggregate numbers.

Head-to-Head Benchmarks

The Ryzen 9 9950X3D dominates the head-to-head matchups, winning 13 of the 15 shared tests, but the EPYC 8224P’s two victories are so extreme that they skew the entire narrative. In Cinebench R23 single-core, the EPYC scores 5,864 against the Ryzen’s 2,259, a staggering 159.6% advantage. The same pattern appears in Cinebench R15 single-core, where the EPYC’s 590 beats the Ryzen’s 350 by 68.6%. These are not marginal wins; they suggest the EPYC’s single-threaded performance is in a completely different class, likely reflecting the benchmark’s sensitivity to the server chip’s architecture.

Everywhere else, the Ryzen 9 9950X3D is the clear winner, often by wide margins. In Cinebench R15 multi-core, it scores 6,536 versus the EPYC’s 4,187, a 35.9% lead. The gap narrows considerably in Cinebench R23 multi-core, where the Ryzen’s 42,018 only edges the EPYC’s 41,542 by 1.1%, but the trend is consistent. PassMark tests show the Ryzen’s dominance across the board: multi-thread at 70,255 versus 48,873 (30.4% ahead), integer math at 243,209 versus 193,256 (20.5% ahead), and floating-point math at 159,724 versus 120,066 (24.8% ahead). The Ryzen also wins data compression by 25%, extended instructions by 36.9%, and find prime numbers by 53.3%.

The single-threaded PassMark results confirm the Ryzen’s superiority in most single-thread workloads, with a score of 4,737 against the EPYC’s 2,357—a 50.2% lead. This creates an interesting paradox: the EPYC wins Cinebench single-core by a landslide, yet loses PassMark single-thread by half. The data implies the EPYC’s single-core advantage is specific to certain instruction patterns, not a general property. The Ryzen’s wins in encryption (2.1%), random string sorting (10.4%), and physics (27.5%) round out a comprehensive sweep.

Architecture Differences

The two chips come from opposite corners of AMD’s design philosophy. The EPYC 8224P is built on Zen 4c, the dense-core variant, and uses the Siena codename within the EPYC 8004 series. It packs 24 cores and 48 threads on a 5 nm TSMC process, with 17,750 million transistors spread across a 2x 73 mm² die. The Ryzen 9 9950X3D uses the newer Zen 5 architecture with the Granite Ridge codename, offering 16 cores and 32 threads on a 4 nm process, with 16,630 million transistors on a 2x 70.6 mm² die. The process node difference—5 nm versus 4 nm—is small but meaningful for power efficiency.

Cache configurations diverge sharply. The EPYC provides 64 MB of shared L3 cache, with 64 KB L1 and 1 MB L2 per core. The Ryzen doubles the L3 to 128 MB, a massive pool that likely explains its strong performance in data-heavy workloads like compression and encryption. The L1 cache also differs: 64 KB per core for the EPYC versus 80 KB per core for the Ryzen. Both use DDR5 memory, but the EPYC supports six-channel memory with a 230.4 GB/s bandwidth, while the Ryzen is dual-channel at 89.6 GB/s—a 2.5x bandwidth advantage for the server chip that the benchmark data doesn’t fully capture.

The sockets and platforms are entirely different ecosystems. The EPYC uses AMD Socket SP6, a server socket with 96 PCIe Gen 5 lanes, while the Ryzen uses AM5 with 24 PCIe Gen 5 lanes. The Ryzen includes integrated Radeon Graphics and an unlocked multiplier, whereas the EPYC has no integrated graphics and a locked multiplier. The EPYC’s TDP is 160 W, slightly lower than the Ryzen’s 170 W, but the core count difference (24 versus 16) means the EPYC delivers more raw throughput per watt in multi-threaded scenarios.

The Verdict

The data points to a clear division: the Ryzen 9 9950X3D is the superior general-purpose processor, winning 13 of 15 head-to-head tests with an average score of 75,779, just 0.9% behind the EPYC’s 76,492. For desktop users, content creators, and gamers, the Ryzen’s wins in multi-thread, integer math, and single-thread PassMark make it the obvious choice. Its 128 MB L3 cache and Zen 5 architecture deliver consistent performance across a wide range of workloads, and the integrated graphics add convenience for systems without a discrete GPU.

The EPYC 8224P, despite losing most benchmarks, has a clear purpose. Its Cinebench single-core results are anomalous—159.6% and 68.6% ahead—and its six-channel memory bandwidth (230.4 GB/s versus 89.6 GB/s) suggests workloads that scale with memory throughput will favor it. Server and workstation applications that rely on dense compute, high core counts, and massive memory bandwidth will find the EPYC’s 24 cores and 48 threads more suitable, even if the Ryzen wins the measured tests. The EPYC’s 96 PCIe lanes also support far more expansion than the Ryzen’s 24.

Specification Differences

The EPYC 8224P has 24 cores and 48 threads, while the Ryzen 9 9950X3D has 16 cores and 32 threads. Base clocks differ dramatically: 2.55 GHz for the EPYC versus 4.30 GHz for the Ryzen, with boost clocks of 3.00 GHz and 5.70 GHz respectively. The EPYC uses the Zen 4c architecture on a 5 nm process with a 2x 73 mm² die and 17,750 million transistors; the Ryzen uses Zen 5 on 4 nm with a 2x 70.6 mm² die and 16,630 million transistors. Cache differs: the EPYC has 64 KB L1 per core, 1 MB L2 per core, and 64 MB shared L3; the Ryzen has 80 KB L1 per core, 1 MB L2 per core, and 128 MB L3. Memory support is DDR5 for both, but the EPYC uses six-channel with 230.4 GB/s bandwidth, while the Ryzen uses dual-channel with 89.6 GB/s. The EPYC has 96 PCIe Gen 5 lanes and no integrated graphics; the Ryzen has 24 PCIe Gen 5 lanes with integrated Radeon Graphics. The EPYC uses Socket SP6 with a locked multiplier; the Ryzen uses AM5 with an unlocked multiplier. TDP is 160 W for the EPYC and 170 W for the Ryzen. The EPYC launched in September 2023, the Ryzen in January 2025.

Where Each One Wins

The Ryzen 9 9950X3D is the winner for virtually every measured workload in the head-to-head data. Its 50.2% lead in PassMark single-thread, 30.4% lead in multi-thread, and 36.9% lead in extended instructions make it the stronger choice for desktop applications, gaming, and content creation. The 128 MB L3 cache and 4 nm Zen 5 architecture give it an edge in data-heavy tasks like compression (25% ahead) and encryption (2.1% ahead), while its 5.70 GHz boost clock and unlocked multiplier offer headroom for enthusiasts. The integrated Radeon Graphics add value for systems without a discrete GPU.

The EPYC 8224P wins in two specific scenarios: Cinebench single-core workloads, where it leads by 159.6% and 68.6%, and any application that can exploit its six-channel memory bandwidth of 230.4 GB/s. Its 24 cores and 48 threads provide raw throughput for server virtualization, database workloads, and scientific computing, even if the Ryzen wins the PassMark multi-thread test. The 96 PCIe Gen 5 lanes allow for extensive expansion, and the 160 W TDP is modest for a 24-core server chip. For embedded and workstation deployments where memory bandwidth and core density matter more than single-thread speed, the EPYC’s architecture is purpose-built. The Ryzen’s 1.1% Cinebench R23 multi-core win suggests the EPYC is nearly competitive in sustained multi-thread rendering, but the overall data favors the Ryzen for general use.
