AMD EPYC 7502 vs AMD Ryzen 5 3500X Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep for the AMD EPYC 7502 across every shared benchmark in the database. In Cinebench R15 multi-core, the EPYC 7502 scores 4428 against the Ryzen 5 3500X’s 1128, a 292.6% advantage. The single-core R15 result follows the same pattern: 625 versus 159, a 293.1% delta. These are not close contests; the EPYC leads by roughly three times in every Cinebench iteration.

Moving to Cinebench R20, the EPYC 7502 posts 18454 in multi-core, while the Ryzen 5 3500X manages 4702. That is a 292.5% gap. In single-core R20, the scores are 2605 and 663, respectively, a 292.9% delta. The pattern holds in Cinebench R23 as well: the EPYC scores 43940 multi-core versus 11196, and 6203 single-core versus 1580. Both deltas sit at 292.5% and 292.6%, respectively. Across all six head-to-head tests, the EPYC 7502 wins every one, with winsA recorded as 6 and winsB as 0.

What stands out is the consistency of the margin. The delta percentages hover tightly between 292.5% and 293.1%, indicating that the performance gap is uniform regardless of workload type or Cinebench version. This is not a case where one chip excels in a niche test; the EPYC 7502 simply outruns the Ryzen 5 3500X by nearly threefold in every measured scenario. The Ryzen 5 3500X has additional benchmarks in the database (3DMark, Geekbench, Passmark) that the EPYC does not share, so those cannot be compared directly, but for the tests where both have recorded scores, the outcome is unambiguous.

The average benchmark score in the database tells a similar story, though with a narrower gap. The EPYC 7502 averages 12709, while the Ryzen 5 3500X averages 12000. The EPYC’s nearest rivals include the Intel Xeon Gold 6348 (delta -0.3%), Intel Core i5-8400 (delta -0.4%), and AMD Ryzen Threadripper 3990X (delta -0.6%), all of which are within a fraction of a percent. The Ryzen 5 3500X sits near the Intel Xeon Bronze 3408U (delta -0.2%), Intel Xeon Gold 6314U (delta -0.2%), and Intel Core i3-12100 (delta -0.4%). Both chips land at the 67th percentile among all CPUs, meaning they occupy similar overall standings in the broader database, but the EPYC’s raw multi-threaded muscle is far greater.

FAQ

Q: Are both processors built on the same architecture?

A: Yes, both use Zen 2 architecture and are fabricated on TSMC’s 7 nm process. The EPYC 7502 uses the Rome codename, while the Ryzen 5 3500X uses Matisse.

Q: Which chip has a higher boost clock?

A: The Ryzen 5 3500X has a higher boost clock at 4.10 GHz, compared to the EPYC 7502’s 3.35 GHz. However, the EPYC’s higher core count dominates in multi-threaded benchmarks.

Architecture Differences

Both processors share the same fundamental Zen 2 architecture and are built on TSMC’s 7 nm process, with the same transistor count of 3,800 million and die size of 74 mm². The foundry is identical, and both use DDR4 memory. The key architectural split lies in their intended roles and the physical layout of resources.

The EPYC 7502, codenamed Rome, is a server and workstation part designed for AMD Socket SP3. It packs 32 cores and 64 threads, with a per-core L1 cache of 96 KB and per-core L2 cache of 512 KB. The L3 cache is a massive 128 MB shared across the chip. Memory access runs through an eight-channel controller, yielding 204.8 GB/s of bandwidth. ECC memory is supported, which is typical for server platforms. The EPYC also supports PCIe Gen 4, though the database does not specify lane count for this part. The multiplier is locked, meaning overclocking is not an option.

The Ryzen 5 3500X, codenamed Matisse, is a desktop part on AMD Socket AM4. It has 6 cores and 6 threads, with a per-core L1 cache of 64 KB and per-core L2 cache of 512 KB. The L3 cache is 32 MB shared, a quarter of the EPYC’s allocation. Memory runs through a dual-channel controller, providing 51.2 GB/s of bandwidth, and ECC memory is not supported. PCIe is Gen 4 with 24 lanes (CPU only). Unlike the EPYC, the Ryzen 5 3500X has an unlocked multiplier, allowing overclocking. The market segments are clearly divided: Server/Workstation for the EPYC, Desktop for the Ryzen.

The architectural differences are not about core design but about scaling. Both use the same Zen 2 cores, but the EPYC replicates them across a much larger chip with more cache and memory channels. The Ryzen 5 3500X is a smaller, more power-efficient part for consumer workloads, while the EPYC 7502 is built to feed many cores with high memory throughput. The lack of integrated graphics on both parts is a shared trait, but the EPYC’s ECC support and eight-channel memory are server-grade features that the desktop chip lacks.

Specification Differences

The two processors diverge sharply on nearly every specification that matters for raw throughput. Core count: 32 versus 6. Thread count: 64 versus 6. Base clock: 2.50 GHz on the EPYC versus 3.60 GHz on the Ryzen 5 3500X. Boost clock: 3.35 GHz versus 4.10 GHz. The Ryzen 5 3500X has higher clock speeds, but the EPYC has vastly more cores.

Thermal design power: the EPYC 7502 is rated at 180 W, while the Ryzen 5 3500X is rated at 65 W. Socket types differ: AMD Socket SP3 for the EPYC, AMD Socket AM4 for the Ryzen. Cache sizes differ substantially: L1 is 96 KB per core on the EPYC versus 64 KB per core on the Ryzen, while L3 is 128 MB shared versus 32 MB shared. Memory bus width is eight-channel versus dual-channel, and memory bandwidth is 204.8 GB/s versus 51.2 GB/s. ECC memory support is present on the EPYC but absent on the Ryzen. PCIe is Gen 4 on both, but the Ryzen explicitly lists 24 lanes (CPU only), while the EPYC’s lane count is not specified in the database.

The multiplier is unlocked on the Ryzen 5 3500X and locked on the EPYC 7502. Release dates differ: the EPYC launched on 2019-08-06, and the Ryzen on 2019-09-23. Part numbers also differ: 100-000000054 for the EPYC, 100-000000158 for the Ryzen. Neither has a launch MSRP listed in the database. Both are marked as Active in production status.

The generation labels differ too: the EPYC is listed as EPYC (Zen 2 (Rome)), while the Ryzen is Ryzen 5 (Zen 2 (Matisse)). The series names are EPYC 7002 series versus 3000 series. Market segment is Server/Workstation for the EPYC, Desktop for the Ryzen. The specification sheet makes the intended use clear: the EPYC is a high-core-count server processor with massive memory bandwidth, while the Ryzen 5 3500X is a mainstream desktop chip with higher clocks and lower power.

Where Each One Wins

The AMD EPYC 7502 wins in every benchmark that the database records for both chips. All six Cinebench tests, spanning R15, R20, and R23 in both multi-core and single-core modes, go to the EPYC with deltas around 292.5% to 293.1%. This makes the EPYC the clear choice for any workload that relies on raw compute throughput, whether single-threaded or heavily parallel. The 32-core, 64-thread configuration, combined with 128 MB of L3 cache and 204.8 GB/s of memory bandwidth, is built for server virtualization, database processing, scientific computing, and other server and workstation tasks. The ECC memory support and eight-channel memory controller further cement its position for reliability and memory-intensive operations.

The AMD Ryzen 5 3500X, despite losing all shared benchmarks, has its own advantages outside the head-to-head tests. The database shows it has a higher base clock (3.60 GHz versus 2.50 GHz) and higher boost clock (4.10 GHz versus 3.35 GHz), which can benefit lightly threaded desktop applications where single-core frequency matters more than core count. The 65 W TDP is much lower than the EPYC’s 180 W, making it suitable for standard desktop builds with modest cooling requirements. The unlocked multiplier on the Ryzen allows overclocking, which is not possible on the locked EPYC. The Ryzen also has additional benchmark scores in 3DMark, Geekbench, and Passmark tests, though those cannot be compared directly to the EPYC because the EPYC lacks recorded scores in those tests.

For a desktop user focused on everyday computing, gaming, and general productivity, the Ryzen 5 3500X is the sensible part due to its lower power draw, higher clocks, and overclocking headroom. For a server administrator or workstation user running multi-threaded enterprise workloads, the EPYC 7502 is the dominant option, offering nearly three times the performance in Cinebench across the board. The data does not show any test where the Ryzen 5 3500X beats the EPYC 7502, so the decision hinges on platform requirements, power budget, and the specific set of workloads outside the shared benchmark suite.
