AMD EPYC 73F3 vs AMD Ryzen 5 3500U Comparison

The Verdict

The AMD EPYC 73F3 is a server-class processor built for sustained multi-threaded workloads, while the AMD Ryzen 5 3500U is a low-power mobile chip designed for everyday portability. The data shows a complete mismatch in capability: the EPYC 73F3 wins both head-to-head benchmarks by massive margins, scoring 507.5% higher in Cinebench R15 multi-core and 289.5% higher in single-core. If your workload demands heavy parallel processing, server-grade memory bandwidth, or ECC reliability, the EPYC 73F3 is the only choice from this pair. If you need a chip for a thin-and-light laptop with integrated graphics and minimal power draw, the Ryzen 5 3500U serves that role, but it cannot compete on raw compute. The EPYC 73F3 sits in the 67th percentile of all CPUs, while the Ryzen 5 3500U sits at 66th — statistically similar overall average scores (11334 vs 11176), but those averages are misleading because the benchmark suites differ. In direct comparison, the EPYC 73F3 is overwhelmingly faster.

Architecture Differences

The two processors come from entirely different design philosophies. The EPYC 73F3 uses the Zen 3 architecture on a 7 nm TSMC process, whereas the Ryzen 5 3500U uses the older Zen+ architecture on a 12 nm GlobalFoundries process. The EPYC 73F3 packs 16 cores and 32 threads, while the Ryzen 5 3500U has just 4 cores and 8 threads. Clock speeds reflect the market split: the EPYC 73F3 has a base clock of 3.50 GHz and boost of 4.00 GHz, compared to 2.10 GHz base and 3.70 GHz boost for the Ryzen. The EPYC 73F3 carries a 240 W TDP on AMD Socket SP3, while the Ryzen 5 3500U draws only 15 W on AMD Socket FP5 — a 16x difference in power envelope.

Cache configurations are radically different. The EPYC 73F3 has 64 KB L1 per core, 512 KB L2 per core, and a massive 256 MB shared L3 cache. The Ryzen 5 3500U has 96 KB L1 per core, 512 KB L2 per core, and just 4 MB shared L3. The EPYC 73F3 is built from 8x 81 mm² chiplets with 33,200 million transistors, while the Ryzen 5 3500U uses a single 210 mm² die with 4,940 million transistors. Memory support also diverges: the EPYC 73F3 runs eight-channel DDR4 with 204.8 GB/s bandwidth and ECC support, while the Ryzen 5 3500U runs dual-channel DDR4 with no ECC and no listed bandwidth figure. The EPYC 73F3 provides PCIe Gen 4 with 128 lanes (CPU only); the Ryzen 5 3500U offers PCIe Gen 3. The EPYC 73F3 has no integrated graphics, whereas the Ryzen 5 3500U includes Radeon Vega 8. The EPYC 73F3 launched in March 2021; the Ryzen 5 3500U launched in January 2019.

Where Each One Wins

The EPYC 73F3 wins every direct benchmark in this comparison. In Cinebench R15 multi-core, it scores 3949 against 650 — a 507.5% advantage. In Cinebench R15 single-core, it scores 557 against 143 — a 289.5% advantage. These results reflect the EPYC 73F3's 16 cores, higher clocks, and larger cache. The Ryzen 5 3500U has no wins in the head-to-head data.

However, the Ryzen 5 3500U has its own domain: mobile computing. It integrates Radeon Vega 8 graphics, which the EPYC 73F3 lacks entirely. The Ryzen 5 3500U's 15 W TDP makes it suitable for thin laptops, while the EPYC 73F3's 240 W TDP demands a server platform with robust cooling. The Ryzen 5 3500U also has a broader benchmark suite in the fact pack, including Geekbench and Passmark tests. Its Passmark multi-thread score is 6858, single-thread is 1924, and it handles data compression at 94555 in Passmark. These numbers show a chip that can manage everyday tasks but is not in the EPYC 73F3's league for heavy compute.

The EPYC 73F3 targets server and workstation workloads with eight-channel memory, ECC support, and 128 PCIe Gen 4 lanes. The Ryzen 5 3500U targets mainstream laptops with dual-channel memory and integrated graphics. If you need a server CPU with massive L3 cache and high core count, the EPYC 73F3 is the pick. If you need a low-power mobile processor with graphics built in, the Ryzen 5 3500U is the pick — but you cannot use it for the same tasks.

FAQ

Head-to-Head Benchmarks

The head-to-head data contains only two Cinebench R15 tests, and the EPYC 73F3 wins both decisively.

In Cinebench R15 multi-core, the EPYC 73F3 scores 3949 against the Ryzen 5 3500U's 650. That is a 507.5% delta — the EPYC 73F3 delivers roughly six times the multi-threaded performance. This is the largest gap in the comparison. The EPYC 73F3's 16 cores at 3.50 GHz base clock simply overwhelm the Ryzen 5 3500U's 4 cores at 2.10 GHz. The 256 MB shared L3 cache on the EPYC 73F3 vs 4 MB on the Ryzen 5 3500U further widens the gap in cache-heavy workloads.

In Cinebench R15 single-core, the EPYC 73F3 scores 557 versus 143 for the Ryzen 5 3500U, a 289.5% difference. Even at single-threaded tasks, the EPYC 73F3 is nearly three times faster. The Zen 3 architecture on 7 nm versus Zen+ on 12 nm explains much of this — newer IPC and higher clocks (4.00 GHz boost vs 3.70 GHz) give the EPYC 73F3 a clear edge.

The Ryzen 5 3500U's own benchmark suite shows it is not a weak chip for its class. Its Cinebench R15 multicore score of 650 and single-core of 143 are low compared to the EPYC 73F3, but its Passmark scores tell a more rounded story: multithread at 6858, single-thread at 1924, floating point math at 12485, integer math at 24732, and data compression at 94555. These numbers indicate a capable mobile processor for everyday computing, but they do not change the fact that the EPYC 73F3 would outperform it in every compute scenario measured here.

The EPYC 73F3's nearest rivals include the AMD EPYC 7402 (0.2% higher average score), Intel Core i5-1145G7 (0.5% higher), and AMD EPYC 7452 (0.5% higher). The Ryzen 5 3500U's nearest rivals include the Intel Xeon Gold 6336Y (0.1% higher), Intel Core i3-1305U (0.2% higher), and AMD EPYC 7542 (0.2% higher). These rival comparisons show both chips are competitive within their own performance tiers, despite the massive gap between them.
