AMD EPYC 74F3 vs AMD Ryzen 3 7320C Comparison

The AMD EPYC 74F3 and the AMD Ryzen 3 7320C occupy opposite ends of the processor spectrum, yet both appear in the database as active products. The EPYC 74F3 is a server-class part designed for massive parallel workloads, while the Ryzen 3 7320C is a low-power mobile chip intended for everyday computing. The recorded benchmark data shows a clear hierarchy, but the details of where each processor excels and fails are worth examining closely.

Head-to-Head Benchmarks

The database includes six head-to-head comparisons, all from the Cinebench suite, and the AMD EPYC 74F3 wins every single one of them. The margins are enormous, reflecting the fundamental difference in core count and design intent.

In Cinebench R15 multicore, the EPYC 74F3 scores 5197 against the Ryzen 3 7320C's 708. That is a 634% advantage. The single-core R15 test tells a similar story: 733 versus 99, a 640.4% delta. These are not close contests; the EPYC 74F3 is faster by a factor of roughly seven in both tests.

Moving to Cinebench R20, the multicore result is 21657 for the EPYC 74F3 versus 2950 for the Ryzen 3 7320C, a 634.1% difference. The single-core R20 score is 3057 against 416, a 634.9% gap. The pattern holds in Cinebench R23 as well: multicore 51566 versus 7025 (634%) and single-core 7279 versus 991 (634.5%).

The consistency of these deltas is striking. Every single-core and multicore comparison lands in the same 634% to 640% range. This suggests the performance difference is not driven by any single architectural feature but by the sheer scale of resources the EPYC 74F3 brings to bear. The Ryzen 3 7320C has 4 cores and 8 threads; the EPYC 74F3 has 24 cores and 48 threads. The EPYC 74F3 also has a significantly larger L3 cache, 256 MB shared versus 4 MB shared on the Ryzen chip.

The single-core results are particularly telling. The Ryzen 3 7320C has a slightly higher boost clock at 4.10 GHz versus 4.00 GHz on the EPYC 74F3, yet the EPYC 74F3 still wins single-core tests by over 600%. This indicates that raw clock speed is not the determining factor here. The Zen 3 architecture of the EPYC 74F3, with its higher instructions per clock, overcomes the Ryzen 3 7320C's frequency advantage.

The wins column shows 6 for the EPYC 74F3 and 0 for the Ryzen 3 7320C. No benchmark in the head-to-head set favors the mobile chip.

The base clock is 2.80 GHz on the EPYC 74F3 versus 2.40 GHz on the Ryzen 3 7320C. The boost clock favors the Ryzen chip slightly: 4.10 GHz versus 4.00 GHz.

Thermal design power could not be more different. The EPYC 74F3 has a TDP of 240 watts, reflecting its server orientation. The Ryzen 3 7320C has a TDP of just 15 watts, a 16-fold difference. This single number explains the form factor and cooling requirements of each platform.

The sockets are incompatible: the EPYC 74F3 uses AMD Socket SP3, while the Ryzen 3 7320C uses AMD Socket FT6. The memory support differs (DDR4 versus LPDDR5), the memory bus width differs (eight-channel versus dual-channel), and the memory bandwidth differs (204.8 GB/s versus 88.0 GB/s). ECC memory support is present on the EPYC 74F3 and absent on the Ryzen 3 7320C.

The release dates are separated by over two years. The EPYC 74F3 launched on 2021-03-14, while the Ryzen 3 7320C launched on 2023-05-22. The EPYC 74F3 has a launch MSRP of $2900; the Ryzen 3 7320C has no launch MSRP listed in the database.

The market segments are explicit: the EPYC 74F3 is a Server/Workstation part, and the Ryzen 3 7320C is a Mobile part. Both are currently in active production.

The Verdict

The data supports a straightforward conclusion: the AMD EPYC 74F3 is the substantially faster processor in every benchmark recorded. Its six head-to-head wins, all by margins exceeding 600%, leave no room for ambiguity. The 24-core, 48-thread configuration with 256 MB of L3 cache and 204.8 GB/s of memory bandwidth is designed for workloads that can utilize massive parallelism, and the Cinebench results confirm it does so effectively.

The Ryzen 3 7320C, by contrast, is not designed to compete with the EPYC 74F3. Its 4 cores, 8 threads, 4 MB of L3 cache, and 15-watt TDP make it a chip for lightweight, power-sensitive devices. The benchmark results reflect its positioning: it scores 7025 in Cinebench R23 multicore, which is less than 14% of the EPYC 74F3's 51566.

The nearest rivals in the database provide context. The EPYC 74F3's average benchmark score of 14915 places it within 0.2% of the Intel Core i7-9750H, 0.4% above the Intel Core i3-10320, and 0.7% above the Intel Core i3-1315U. It trails the AMD EPYC 7702P by 1.4%. The Ryzen 3 7320C's average score of 14277 places it 0.3% below the AMD Ryzen 5 3501U, 0.3% above the Intel Core 7 160UL, 0.4% below the AMD Ryzen Embedded V2546, and 0.7% above the Intel Core i5-10400F. These rival comparisons show that both processors are competitive within their own performance strata, even though they are far apart from each other.

Where Each One Wins

The AMD EPYC 74F3 wins in all measured compute scenarios. The head-to-head benchmark set covers single-core and multicore tests across three versions of Cinebench, and the EPYC 74F3 leads in each. The largest single margin is in Cinebench R15 single-core at 640.4%, while the smallest is in Cinebench R23 multicore at 634%. The consistency of these margins suggests that the EPYC 74F3's advantage is structural rather than workload-specific. Any task that relies on raw CPU throughput, whether single-threaded or multi-threaded, will favor the EPYC 74F3 according to the recorded data.

The Ryzen 3 7320C's wins are not in the head-to-head benchmarks, because it has none. However, the database includes additional PassMark scores for the Ryzen 3 7320C that are not matched by the EPYC 74F3 in this dataset. These include a data compression score of 144465, data encryption of 5443, extended instructions of 3663, and several other workloads. These scores are recorded only for the Ryzen 3 7320C, so they cannot be directly compared to the EPYC 74F3. What they do show is that the Ryzen 3 7320C is a functional, capable mobile processor in its own right.

The practical choice between these two processors depends entirely on the platform requirements. For a server or workstation where power consumption, cooling, and cost are secondary considerations, the EPYC 74F3 is the clear choice based on benchmark performance. For a mobile device where the 15-watt TDP, integrated Radeon 610M graphics, and compact FT6 socket are essential, the Ryzen 3 7320C is the appropriate part. Neither processor is a substitute for the other; they are built for different ecosystems and different workloads.

The percentile ranking for both processors is identical at 69, meaning they sit at the same relative position among all CPUs in the database. This is a reminder that percentile ranks do not capture the absolute performance gap between these two parts. The EPYC 74F3 achieves its rank with high absolute scores, while the Ryzen 3 7320C achieves the same rank within a much lower absolute range, likely due to the distribution of mobile and desktop parts in the database.

In summary, the AMD EPYC 74F3 dominates the head-to-head benchmarks with six wins and margins between 634% and 640.4%. The AMD Ryzen 3 7320C offers no benchmark wins in this comparison but provides a low-power, integrated-graphics solution for mobile computing. The data does not suggest any scenario where the Ryzen 3 7320C outperforms the EPYC 74F3 in the recorded tests; it simply serves a different market segment with different priorities.
