AMD EPYC 7413 vs AMD EPYC Embedded 8224P Comparison

Head-to-Head Benchmarks

The benchmark data shows a clear overall winner: the AMD EPYC 7413 takes 14 of 17 head-to-head tests, while the AMD EPYC Embedded 8224P manages only 3 wins. The margin of victory varies substantially by workload, which reveals distinct performance profiles despite both parts having 24 cores and 48 threads.

In the Cinebench suite, the EPYC 7413 is consistently ahead by 3.6% to 3.7% across every render test. The R15 multicore result is 4338 versus 4187, while R15 singlecore is 612 versus 590. R20 multicore shows 18078 against 17447, and R20 singlecore is 2551 versus 2462. The R23 results follow the same pattern: 43044 versus 41542 in multicore and 6076 versus 5864 in singlecore. These are uniform, predictable margins, suggesting a clock-speed advantage that scales evenly across both single-threaded and multi-threaded rendering workloads.

The Passmark integer math test favors the EPYC 7413 by 11.6%, with a score of 215629 versus 193256. Data encryption shows an even larger gap at 11.2%, scoring 48492 versus 43619. The physics test produces a 14.5% lead for the EPYC 7413, at 4708 versus 4110. The most dramatic difference appears in the find prime numbers test, where the EPYC 7413 scores 397 against 286, a 38.8% advantage. This is the single largest delta in the entire comparison and points to a significant architectural difference in how the two processors handle this specific workload pattern.

The EPYC 7413 also leads in data compression by 5%, scoring 715616 versus 681754, and in Passmark multithread by 3.6%, at 50641 versus 48873. Single-thread performance in Passmark is closer, with the EPYC 7413 ahead by just 1.8%, scoring 2400 versus 2357.

The EPYC Embedded 8224P's three wins are narrower and more specialized. It takes floating point math by 1%, scoring 120066 versus 118881. Extended instructions go to the 8224P by 0.9%, at 46091 versus 45696. Random string sorting is its largest win at 5.1%, with 85505 versus 81134. These wins suggest the Zen 4c architecture brings genuine improvements in certain instruction-heavy or memory-access-pattern-sensitive tasks, but they are not enough to offset the 7413's dominance elsewhere.

The average benchmark score reinforces this picture: the EPYC 7413 averages 80041, while the EPYC Embedded 8224P averages 76492. Both sit at the 95th percentile of all CPUs in the database, so neither is a weak performer, but the 7413 is consistently stronger across a broader range of workloads.

FAQ

A: In Cinebench R23 multicore, the EPYC 7413 scores 43044 versus 41542 for the 8224P, a 3.6% advantage. The same 3.6% delta appears in R15 multicore (4338 versus 4187) and R20 multicore (18078 versus 17447).

Q: In which test does the EPYC Embedded 8224P show its biggest advantage?

A: The 8224P wins random string sorting by 5.1%, scoring 85505 versus 81134. It also edges out the 7413 in floating point math by 1% and extended instructions by 0.9%, but those are the only three tests it wins.

Q: What is the largest performance gap between the two processors?

A: The largest gap is in the Passmark find prime numbers test, where the EPYC 7413 scores 397 versus 286, a 38.8% advantage. This is more than three times larger than the next biggest delta, which is the 14.5% lead in the physics test.

Q: How do these processors compare to their nearest rivals in the database?

A: The EPYC 7413 has an average score of 80041, placing it 0.6% ahead of the Intel Core Ultra 9 290HX Plus, 0.8% ahead of the Intel Core i9-14900KF, and 0.8% behind both the Intel Xeon w5-2565X and the Intel Xeon 638. The EPYC Embedded 8224P averages 76492, essentially tied with the AMD Ryzen Threadripper PRO 9945WX, 0.4% behind the AMD Ryzen 9 8945HX and the Intel Core Ultra 9 285HX, and 0.9% ahead of the AMD Ryzen 9 9950X3D.

Q: Do both processors support ECC memory?

A: Yes, both the EPYC 7413 and the EPYC Embedded 8224P have ECC memory support. They differ in memory type, however: the 7413 uses DDR4 with an eight-channel bus, while the 8224P uses DDR5 with a six-channel bus.

The Verdict

The benchmark data indicates that the AMD EPYC 7413 is the stronger performer in almost every category. It leads in all six Cinebench tests, all three Passmark math tests except floating point, both memory-heavy tests (compression and encryption), the physics test, and the multithread test. Its 38.8% advantage in prime number finding is particularly striking and suggests that workloads relying on integer-heavy, branch-intensive computation will see outsized benefits from choosing the 7413.

The AMD EPYC Embedded 8224P is not without merit. Its wins in floating point math, extended instructions, and random string sorting show that the Zen 4c architecture handles certain vectorized and memory-access-pattern-sensitive workloads slightly better. The 5.1% lead in random string sorting could matter for specific data-processing pipelines. However, these are narrow margins, and they come in only 3 of 17 tests.

For buyers prioritizing raw compute throughput across a broad mix of server workloads, the EPYC 7413 is the clear choice from the data. For workloads that specifically involve floating point math, extended instruction sets, or random string sorting, the 8224P offers a marginal edge, though the overall average benchmark score still favors the 7413 by 4.6% (80041 versus 76492). The 8224P also has a lower TDP of 160 watts versus 180 watts, which could influence platform-level decisions, but the performance data itself points firmly toward the 7413.

Specification Differences

The two processors share the same core and thread counts: 24 cores and 48 threads each. Both are active production parts from AMD, target the server/workstation market segment, have ECC memory support, lack integrated graphics, and are not multiplier unlocked. Their part numbers differ, and the EPYC 7413 has a launch MSRP of $1825, while the 8224P has no listed launch MSRP.

The EPYC 7413 uses a base clock of 2.65 GHz and a boost clock of 3.60 GHz, with a TDP of 180 watts. The EPYC Embedded 8224P runs at 2.55 GHz base and 3.00 GHz boost, with a TDP of 160 watts. The 7413 sits in an AMD Socket SP3, while the 8224P uses AMD Socket SP6.

Memory configurations differ significantly. The 7413 supports DDR4 with an eight-channel memory bus and a bandwidth of 204.8 GB/s. The 8224P supports DDR5 with a six-channel bus and a higher bandwidth of 230.4 GB/s. PCIe connectivity also differs: the 7413 offers Gen 4 with 128 lanes (CPU only), while the 8224P offers Gen 5 with 96 lanes (CPU only).

Release dates are separated by about two and a half years: the 7413 was released in March 2021, and the 8224P was released in September 2023.

Architecture Differences

The EPYC 7413 belongs to the EPYC 7003 series and uses the Zen 3 architecture, codenamed Milan. The EPYC Embedded 8224P belongs to the EPYC 8004 series and uses the Zen 4c architecture, codenamed Siena. This is a fundamental architectural split: the 7413 is a full-size Zen 3 design, while the 8224P uses the dense Zen 4c variant, which trades some clock speed and cache for higher core density and efficiency.

The process nodes differ. The 7413 is built on TSMC's 7 nm process, while the 8224P uses TSMC's 5 nm process. Transistor counts are close but not identical: the 7413 has 16,600 million transistors across a die size of 4x 81 mm², while the 8224P has 17,750 million transistors across a die size of 2x 73 mm². The newer process node and smaller total die area explain how the 8224P achieves similar core counts with a lower TDP.

Cache configurations show meaningful differences. Both have 64 KB of L1 cache per core and 512 KB of L2 cache per core for the 7413, but the 8224P doubles the L2 to 1 MB per core. The L3 cache goes the other way: the 7413 has 128 MB shared, while the 8224P has 64 MB shared. This halved L3 cache likely contributes to the 7413's advantage in cache-sensitive workloads like prime number finding, while the larger per-core L2 may help the 8224P in floating point and string sorting tasks.

The 8224P's Zen 4c cores are designed for density rather than maximum frequency, which aligns with its lower boost clock of 3.00 GHz versus 3.60 GHz. The 7413's Zen 3 cores are larger and clock higher, which explains its consistent lead in single-threaded tests. The 8224P does compensate with DDR5 support and a higher memory bandwidth of 230.4 GB/s, along with PCIe Gen 5, but the benchmark data shows these advantages do not translate into overall performance leadership.
