AMD EPYC 73F3 vs AMD Ryzen 5 3500X Comparison

Head-to-Head Benchmarks

The benchmark data presents a one-sided contest. Across all six shared Cinebench tests, the AMD EPYC 73F3 records the higher score, with the Ryzen 5 3500X trailing by a consistent margin of roughly 71.4% to 71.5% in every workload. The largest absolute gap appears in Cinebench R23 multicore, where the EPYC 73F3 scores 39,187 against the Ryzen 5 3500X's 11,196, a difference of 27,991 points. That margin reflects the EPYC part's 16 cores and 32 threads versus the Ryzen 5's 6 cores and 6 threads, a structural advantage that scales directly into highly threaded rendering workloads.

Single-core results tell a similar story, though the percentage deficit is nearly identical. In Cinebench R23 single-core, the EPYC 73F3 posts 5,532 while the Ryzen 5 3500X manages 1,580, a delta of 71.4%. The same pattern repeats in Cinebench R15 single-core, where the EPYC 73F3 scores 557 versus 159, and in Cinebench R20 single-core, where the EPYC 73F3 scores 2,323 versus 663. Both deltas sit at 71.5%, indicating that the EPYC 73F3's per-thread performance advantage is not a quirk of one benchmark generation but a consistent property across all three Cinebench versions.

The multicore deltas are equally uniform: 71.4% in R15, R20, and R23. This consistency suggests the Ryzen 5 3500X is not merely outgunned by core count, but also by per-core efficiency. The EPYC 73F3's Zen 3 architecture delivers higher instructions per clock than the Ryzen 5 3500X's Zen 2 design, and the benchmark results confirm that advantage in both single-threaded and multi-threaded tests. The head-to-head tally is unambiguous: the EPYC 73F3 wins all six recorded comparisons. The Ryzen 5 3500X records zero wins in the shared benchmark suite.

Looking at the broader database, the Ryzen 5 3500X holds an average benchmark score of 12,000 and sits at the 67th percentile of all CPUs. Its nearest rivals include the Intel Xeon Bronze 3408U at 12,019 (0.2% ahead), the Intel Xeon Gold 6314U at 12,026 (0.2% ahead), and the Intel Core i3-12100 at 12,054 (0.4% ahead). The Intel Core i7-7700 trails by 0.7% with a score of 11,914. These close deltas indicate the Ryzen 5 3500X occupies a tightly contested performance band among desktop and entry server parts.

The EPYC 73F3, despite its dominant head-to-head showing, records a lower average benchmark score of 11,334, also at the 67th percentile. Its nearest rivals include the AMD EPYC 7402 at 11,312 (0.2% behind), the Intel Core i5-1145G7 at 11,279 (0.5% behind), and the AMD EPYC 7452 at 11,279 (0.5% behind). The Intel Core i3-1305U trails by 1.2% with a score of 11,200. This discrepancy between the EPYC 73F3's head-to-head wins and its lower average score reflects the benchmark set composition: the head-to-head suite is limited to Cinebench, where the EPYC 73F3 excels, while the average score incorporates a wider range of workloads, some of which may not favor the server part's architecture.

Architecture Differences

The two processors belong to different AMD generations and market segments. The Ryzen 5 3500X is a desktop part from the 3000 series, built on the Zen 2 architecture with the Matisse codename. It uses the AMD Socket AM4 platform. The EPYC 73F3 is a server and workstation processor built on the Zen 3 architecture with the Milan codename, using the AMD Socket SP3 platform. The generation fields confirm this split: the Ryzen 5 3500X is listed under "Ryzen 5 (Zen 2 (Matisse))", while the EPYC 73F3 is listed under "EPYC (Zen 3 (Milan))".

Both chips are fabricated on a 7 nm process at TSMC, but the die configurations differ sharply. The Ryzen 5 3500X integrates 3,800 million transistors on a single 74 mm² die. The EPYC 73F3 integrates 33,200 million transistors across eight chiplets, each measuring 81 mm², for a total die area of 648 mm². That is an 8x difference in transistor count and a roughly 8.8x difference in total silicon area, which explains the EPYC part's substantially higher core count and larger cache pool.

Cache hierarchies also diverge. Both processors feature 64 KB of L1 cache per core and 512 KB of L2 cache per core. The L3 cache, however, is dramatically different: the Ryzen 5 3500X offers 32 MB shared, while the EPYC 73F3 offers 256 MB shared. That is an 8x increase in last-level cache, directly benefiting the EPYC part in workloads with large working sets, such as database processing, virtualization, and high-performance computing simulations.

Memory support is another major differentiator. The Ryzen 5 3500X uses dual-channel DDR4 with a memory bandwidth of 51.2 GB/s and does not support ECC memory. The EPYC 73F3 uses eight-channel DDR4 with a memory bandwidth of 204.8 GB/s and supports ECC memory. The 4x bandwidth advantage and ECC capability align with the EPYC part's server positioning, where memory reliability and throughput are critical.

PCIe connectivity follows the same pattern. The Ryzen 5 3500X provides 24 PCIe Gen 4 lanes from the CPU, while the EPYC 73F3 provides 128 PCIe Gen 4 lanes. The 104-lane difference enables the EPYC part to attach many more storage devices, accelerators, and network interfaces directly to the processor, a requirement for dense server configurations. The Ryzen 5 3500X has an unlocked multiplier, while the EPYC 73F3 does not, reflecting their intended usage models: enthusiast desktop tuning versus fixed server operation.

The EPYC 73F3 carries a launch MSRP of $3521. The Ryzen 5 3500X has no recorded launch MSRP in the database, and the EPYC 73F3's price is stated here only as a point of record. Clock speeds are close: the Ryzen 5 3500X has a base clock of 3.60 GHz and a boost clock of 4.10 GHz, while the EPYC 73F3 has a base clock of 3.50 GHz and a boost clock of 4.00 GHz. Despite the EPYC part's lower nominal clocks, its Zen 3 architecture and higher core count deliver superior results in every recorded Cinebench test.

FAQ

A: The Ryzen 5 3500X supports dual-channel DDR4 with 51.2 GB/s bandwidth and no ECC. The EPYC 73F3 supports eight-channel DDR4 with 204.8 GB/s bandwidth and ECC memory support.

Q: Are both processors on the same manufacturing process?

A: Yes, both are fabricated on a 7 nm process at TSMC. However, the Ryzen 5 3500X uses a single 74 mm² die with 3,800 million transistors, while the EPYC 73F3 uses eight chiplets of 81 mm² each, totaling 33,200 million transistors.

Q: How do their average benchmark scores compare?

A: The Ryzen 5 3500X has an average benchmark score of 12,000 at the 67th percentile, while the EPYC 73F3 has an average score of 11,334, also at the 67th percentile. The Ryzen 5 is slightly ahead in the broader average, despite losing every head-to-head Cinebench test.

The Verdict

The data supports a clear division of roles. The AMD EPYC 73F3 is the superior processor for heavily threaded, cache-sensitive, and memory-intensive workloads. Its 16 cores, 32 threads, 256 MB L3 cache, eight-channel memory, and ECC support make it the appropriate choice for server and workstation deployments where throughput and reliability outweigh other considerations. The Cinebench results confirm this: the EPYC 73F3 leads by 71.4% in every multicore test and by 71.4% to 71.5% in every single-core test. Its 128 PCIe Gen 4 lanes and 204.8 GB/s memory bandwidth further position it for large-scale data movement.

The Ryzen 5 3500X, by contrast, is a desktop processor with a 65 W TDP, an unlocked multiplier, and a smaller footprint. Its 6 cores and 6 threads are sufficient for mainstream desktop workloads, and its average benchmark score of 12,000 edges out the EPYC 73F3's 11,334 in the database's broader scoring. The Ryzen 5 3500X also runs on the AM4 platform, which is oriented toward consumer motherboards and memory configurations. For users building a general-purpose desktop system, the Ryzen 5 3500X offers the more appropriate feature set, including a lower TDP and overclocking support.

The choice between these two processors should be guided by workload type, not raw score comparisons. The EPYC 73F3 wins every recorded head-to-head test, but its lower average benchmark score and lack of an unlocked multiplier indicate it is tuned for a specific server niche. The Ryzen 5 3500X, despite losing all six Cinebench comparisons, holds its own in the broader benchmark average and offers characteristics such as a 65 W TDP and unlocked multiplier that server parts do not provide. In short, the EPYC 73F3 is for compute-density-focused server environments; the Ryzen 5 3500X is for desktop builds where flexibility and lower power are priorities.
