AMD EPYC 74F3 vs AMD Ryzen 5 5500U Comparison

The AMD EPYC 74F3 and AMD Ryzen 5 5500U occupy opposite ends of the processor spectrum, yet both post identical 69th-percentile scores in the global database. This parity is misleading, as the average benchmark score for the EPYC 74F3 is 14,915, while the Ryzen 5 5500U trails slightly at 14,589. The data reveals a server-grade 24-core Milan part against a 6-core Lucienne mobile chip, with the EPYC holding a 0.2% edge over the Intel Core i7-9750H and the Ryzen 5 sitting 0.1% above the AMD EPYC 7473X. Their head-to-head results, however, are anything but close.

Head-to-Head Benchmarks

The EPYC 74F3 dominates every shared benchmark test, with the largest margin appearing in multi-threaded workloads. In Cinebench R23 multi-core, the EPYC scores 51,566 against the Ryzen 5's 7,186, a staggering 617.6% advantage. This gap stems directly from the core count disparity: 24 physical cores with 48 threads versus 6 cores with 12 threads. The single-core results tell a similar story, though with a smaller delta. The EPYC posts 7,279 in Cinebench R23 single-core versus 1,172 for the Ryzen 5, a 521.1% difference. Notably, the EPYC's boost clock of 4.00 GHz matches the Ryzen 5's boost clock exactly, so the single-core gap is not a clock-speed story but rather a generational architecture one.

Cinebench R15 results reinforce the pattern. The EPYC 74F3 scores 5,197 in multi-core, beating the Ryzen 5's 1,247 by 316.8%. In R15 single-core, the EPYC's 733 edges out the Ryzen 5's 177 by 314.1%. These four head-to-head tests produce a clean sweep: winsA equals 4, winsB equals 0. The Ryzen 5 5500U has no benchmark in the shared set where it outperforms the EPYC 74F3, which is expected given the server part's 4x core count and 8x thread count. The percentile rankings being identical at 69 is a quirk of the averaging methodology, not an indicator of performance equivalence.

Where Each One Wins

The EPYC 74F3 wins in every scenario that involves CPU compute throughput. Its Cinebench scores indicate leadership in rendering, video encoding, and any parallel workload that scales across 48 threads. The 256 MB of shared L3 cache, combined with eight-channel DDR4 memory delivering 204.8 GB/s bandwidth, makes it suited for large in-memory databases, virtualization hosts, and scientific simulation. The data shows the EPYC 74F3's average benchmark score of 14,915 places it in the same performance band as the Intel Core i7-9750H (14,886) and Intel Core i3-10320 (14,852), though those rivals are far lower in core count. The EPYC 7702P, a previous-generation server part, scores 15,130, just 1.4% higher, indicating the 74F3 is competitive within its own server lineage.

The Ryzen 5 5500U wins in scenarios where the EPYC cannot compete at all: integrated graphics, power envelope, and platform footprint. The Ryzen 5 includes Radeon Graphics with 448SP, while the EPYC 74F3 has no integrated graphics. The Ryzen 5's 15 W TDP versus the EPYC's 240 W TDP makes the mobile chip viable for thin-and-light laptops, whereas the EPYC requires a server platform with AMD Socket SP3. The Ryzen 5's benchmark suite includes 3DMark tests (single-thread: 684, 2-thread: 1,354, 4-thread: 2,446, 8-thread: 3,259, 16-thread: 3,741, max-thread: 3,643) and Geekbench results (single-core: 1,292, multi-core: 4,965), which the EPYC lacks. For single-threaded integer workloads like the PassMark single-thread test (2,419), the Ryzen 5 demonstrates that a lower-core mobile part can still deliver responsive everyday performance, even if it cannot match the EPYC's brute force.

Architecture Differences

The EPYC 74F3 is built on Zen 3 architecture under the Milan codename, while the Ryzen 5 5500U uses Zen 2 architecture under the Lucienne codename. Both are fabricated on TSMC's 7 nm process, but the similarities end there. The EPYC's transistor count is 33,200 million spread across four 81 mm² dies, whereas the Ryzen 5 packs 9,800 million transistors into a single 156 mm² die. This chiplet-based design for the EPYC enables the massive 256 MB shared L3 cache, compared to the Ryzen 5's 8 MB shared L3. Both parts use 64 KB L1 and 512 KB L2 per core, but the EPYC's 24 cores collectively access a much larger cache hierarchy.

Memory architecture diverges sharply. The EPYC 74F3 supports DDR4 over an eight-channel memory bus, yielding 204.8 GB/s of bandwidth. The Ryzen 5 5500U uses DDR4 over a dual-channel bus, delivering 51.2 GB/s. Both support DDR4, but the EPYC also includes ECC memory support, which the Ryzen 5 lacks. PCIe capabilities differ as well: the EPYC offers Gen 4 with 128 lanes (CPU only), while the Ryzen 5 provides Gen 3 with 12 lanes (CPU only). The EPYC is a server/workstation part with a release date of March 14, 2021, while the Ryzen 5 is a mobile part released earlier on January 11, 2021. The EPYC features four dies, suggesting NUMA considerations, whereas the Ryzen 5 is a monolithic die.

Specification Differences

The core and thread counts present the most obvious divergence: 24 cores and 48 threads for the EPYC 74F3 versus 6 cores and 12 threads for the Ryzen 5 5500U. Base clock speeds differ at 2.80 GHz for the EPYC and 2.10 GHz for the Ryzen 5, though boost clocks match at 4.00 GHz. The TDP ratings are extreme opposites: 240 W for the server part versus 15 W for the mobile chip. Sockets are incompatible: AMD Socket SP3 for the EPYC, AMD Socket FP6 for the Ryzen 5. The EPYC has a launch MSRP of $2900, while the Ryzen 5 has no launch MSRP listed. The EPYC measures 4x 81 mm² die size, while the Ryzen 5 uses a single 156 mm² die. Transistors differ at 33,200 million versus 9,800 million. L3 cache is 256 MB shared for the EPYC versus 8 MB shared for the Ryzen 5. Memory bus width is eight-channel versus dual-channel, with memory bandwidth at 204.8 GB/s versus 51.2 GB/s. ECC support is present on the EPYC and absent on the Ryzen 5. PCIe generation and lane counts differ: Gen 4 with 128 lanes versus Gen 3 with 12 lanes. The EPYC has no integrated graphics, while the Ryzen 5 includes Radeon Graphics with 448SP. Market segments are Server/Workstation versus Mobile. The part numbers differ: 100-000000317100-100000317WOF for the EPYC, 100-000000375 for the Ryzen 5. Both are active in production and neither has an unlocked multiplier.
