AMD EPYC 7413 vs AMD EPYC 7443P Comparison

The AMD EPYC 7443P is decisively the faster processor in this head-to-head comparison, winning all 17 benchmark comparisons against the AMD EPYC 7413. The performance gap is consistent across single-threaded, multi-threaded, and specialized workloads, driven entirely by higher clock speeds on the same 24-core Zen 3 architecture. While both chips share the same core count, cache size, and memory subsystem, the 7443P’s advantage in base and boost clocks translates into a commanding lead that ranges from a marginal 0.8% to a substantial 21.1% depending on the workload.

Head-to-Head Benchmarks

The most lopsided victory for the EPYC 7443P comes in single-thread performance, where it scores 2907 in PassMark’s single-thread test compared to 2400 for the 7413, a 21.1% advantage. This is the largest delta in the entire benchmark suite and aligns perfectly with the 7443P’s higher boost clock. Cinebench R23 single-core results echo this trend, with the 7443P posting 6837 versus 6076, a 12.5% lead. These figures indicate that for lightly threaded server management tasks, database queries, or any application that relies on single-core responsiveness, the 7443P offers a tangible performance uplift.

Multi-threaded workloads also favor the 7443P heavily. In Cinebench R23 multi-core, the 7443P scores 48433 against 43044 for the 7413, another 12.5% margin. The pattern is nearly identical across all Cinebench versions: R15 multi-core shows 4881 versus 4338, and R20 multi-core shows 20341 versus 18078, both with the same 12.5% delta. PassMark’s multithread test confirms this, with the 7443P achieving 56981 versus 50641, again a 12.5% difference. This consistent 12.5% gap across all multi-threaded Cinebench tests suggests a perfectly scalable clock-frequency advantage, as both CPUs have identical core and thread counts.

The 7443P’s lead extends into specialized workloads, though the magnitude varies. Data encryption shows an 18.1% advantage (57263 versus 48492), while random string sorting is close behind at 17.8% (95581 versus 81134). Data compression shows a 14.7% difference (820859 versus 715616). These memory and I/O-heavy tasks benefit disproportionately from the 7443P’s higher clocks, indicating that the performance advantage is not limited to pure compute but also improves data throughput operations. Floating-point math shows a 9.3% lead (129932 versus 118881), while integer math is 7.9% ahead (232632 versus 215629).

The smallest margins are found in passmark_physics and find_prime_numbers. The physics test shows a mere 0.8% difference (4748 versus 4708), which is nearly a tie. Prime number finding shows a 3.3% advantage (410 versus 397). Extended instructions are 5.5% faster on the 7443P (48213 versus 45696). These results suggest that certain highly specialized or latency-bound workloads do not scale as well with clock speed, but even in these cases, the 7443P maintains a lead. Across all 17 head-to-head tests, the EPYC 7443P wins every single one, with an average benchmark score of 81661 compared to 80041 for the 7413, a 2% overall difference according to the nearestRivals data.

Architecture Differences

Both processors are built on the same fundamental architecture, which explains their broad similarity. They share the Zen 3 microarchitecture, the Milan codename, and the EPYC (Zen 3 (Milan)) generation. Both are manufactured on TSMC’s 7 nm process node, with identical transistor counts of 16,600 million and the same die configuration of 4x 81 mm². This means there is no architectural advantage in terms of IPC (instructions per clock) — the silicon is essentially the same.

The core and cache configurations are also identical. Both have 24 cores and 48 threads, with 64 KB of L1 cache per core, 512 KB of L2 cache per core, and a shared 128 MB L3 cache. Memory support is also equal: DDR4 with an eight-channel memory bus and 204.8 GB/s of memory bandwidth. Both support ECC memory, which is critical for server reliability. PCIe connectivity is the same, with Gen 4 and 128 lanes (CPU only). Neither chip has integrated graphics, and both are unlocked multipliers are not available (multiplierUnlocked is false).

The only architectural difference lies in clock speeds. The EPYC 7443P has a base clock of 2.85 GHz and a boost clock of 4.00 GHz, while the EPYC 7413 has a base clock of 2.65 GHz and a boost clock of 3.60 GHz. This 0.2 GHz difference in base clock and 0.4 GHz difference in boost clock is the sole source of the performance disparity. Consequently, the 7443P has a higher thermal design power (TDP) of 200 watts, compared to 180 watts for the 7413. Both use the same AMD Socket SP3, so they are drop-in compatible for existing server platforms.

Where Each One Wins

The AMD EPYC 7443P wins in every single benchmark category tested, so its dominance is absolute. Its largest advantages come in single-threaded performance (21.1% in PassMark single-thread) and data encryption (18.1%). For workloads that are heavily dependent on clock speed — such as real-time transaction processing, high-frequency trading, or any latency-sensitive application — the 7443P is the clear choice. Its 4.00 GHz boost clock provides a significant edge over the 7413’s 3.60 GHz boost clock. Data compression and random string sorting also favor the 7443P by 14.7% and 17.8% respectively, making it better suited for database workloads and storage-related tasks.

The AMD EPYC 7413 does not win any benchmark, but its performance is not dramatically worse in all areas. In the passmark_physics test, the difference is only 0.8%, which is within the margin of error for most real-world scenarios. Similarly, prime number finding shows only a 3.3% gap. For workloads that are heavily memory-bound or that do not scale perfectly with clock speed, the 7413 provides nearly comparable performance. Its lower TDP of 180 watts means it draws less power, which could be a consideration for dense server deployments where thermal constraints are a factor, although this is not a performance win.

The Verdict

The data is unambiguous: the AMD EPYC 7443P is the superior processor in every measurable way. It offers a consistent 12.5% advantage across all Cinebench multi-core and single-core tests, and even larger leads in encryption and single-thread PassMark tests. For any application that can utilize the higher clock speeds, the 7443P will deliver more throughput. The 2% higher average benchmark score (81661 versus 80041) confirms its overall performance lead. The 7443P also carries a lower launch MSRP of $1337 compared to $1825 for the 7413, making it the better-performing option at a lower stated price.

The only reason to consider the AMD EPYC 7413 would be its lower TDP of 180 watts, which may be relevant in power-constrained environments. Its performance in physics and prime number tests is nearly identical to the 7443P, suggesting that certain specialized workloads do not benefit from higher clocks. However, with zero benchmark wins and a higher launch MSRP, the 7413 offers no performance-based justification for selection. The conclusion from the benchmark data is clear: the EPYC 7443P is the recommended choice for nearly all server and workstation scenarios, providing faster single-threaded responsiveness and substantially higher multi-threaded throughput.
