AMD EPYC 4584PX vs AMD EPYC 7413 Comparison

The Verdict

The AMD EPYC 4584PX is the overwhelming winner in the recorded benchmark suite, taking 14 of 17 head-to-head tests. Its advantages are most pronounced in single-threaded workloads, where it leads by 58.1% in PassMark single-thread performance, and in Cinebench tests, where it leads by roughly 19.7% across the board. The EPYC 7413, however, retains advantages in three specific areas: data encryption (5.3% faster), integer math (6.4% faster), and physics (2.8% faster). For workloads dominated by integer arithmetic, cryptographic operations, or specific physics simulations, the older 24-core Milan part still holds ground. For nearly everything else, including multi-threaded rendering, extended instruction workloads, and random string sorting, the 4584PX's architectural efficiency and high clock speeds carry the day.

The 4584PX also holds a slight edge in overall database standing, with a 96th percentile ranking versus the 7413's 95th percentile, and an average benchmark score of 83090 compared to 80041. Its nearest rivals in the database include the AMD EPYC 9135 (0.1% higher average score), Intel Core Ultra 9 285K (0.9% higher), and AMD EPYC 7443P (1.8% lower). The 7413 sits near the Intel Core Ultra 9 290HX Plus (0.6% higher) and Intel Core i9-14900KF (0.8% lower). The data indicates that buyers seeking maximum single-core responsiveness and modern platform features should choose the 4584PX, while those with integer-heavy or encryption-heavy server workloads, and who can accommodate the 7413's larger memory bandwidth, may still find the 7413 relevant.

Architecture Differences

The two processors come from different EPYC generations and implement different microarchitectures. The AMD EPYC 4584PX is built on the Zen 4 architecture with the Raphael codename, while the AMD EPYC 7413 uses the Zen 3 architecture with the Milan codename. The 4584PX is part of the EPYC 4004 series, and the 7413 belongs to the EPYC 7003 series.

The manufacturing process differs as well. The 4584PX is fabricated on a 5 nm process at TSMC, with a transistor count of 17,840 million and a die size of 2x 71 mm². The 7413 uses a 7 nm process at TSMC, with 16,600 million transistors and a die size of 4x 81 mm². The smaller geometry and higher transistor count of the 4584PX contribute to its higher clock speeds and better per-core efficiency.

Cache organization is identical in L1 and L3: both have 64 KB of L1 per core and 128 MB of shared L3. The L2 cache differs: the 4584PX has 1 MB per core, while the 7413 has 512 KB per core. Additionally, the 4584PX includes a 3D V-Cache slice of 1x 64 MB, which likely boosts its L3-related performance characteristics.

Platform features diverge sharply. The 4584PX uses AMD Socket AM5, supports DDR5 memory on a dual-channel bus, and provides PCIe Gen 5 with 28 lanes (CPU only). It also includes integrated Radeon Graphics. The 7413 uses AMD Socket SP3, supports DDR4 memory on an eight-channel bus, and provides PCIe Gen 4 with 128 lanes (CPU only). It has no integrated graphics. Both support ECC memory. The 4584PX was released on 2024-05-20, while the 7413 was released on 2021-03-14. The launch MSRP for the 4584PX is $699, and for the 7413 it is $1825.

Specification Differences

The core and thread counts differ: the 4584PX has 16 cores and 32 threads, while the 7413 has 24 cores and 48 threads. The 7413 offers 50% more cores and threads, yet the 4584PX wins most multi-threaded benchmarks due to its higher clocks and newer architecture.

Clock speeds are dramatically different. The 4584PX has a base clock of 4.20 GHz and a boost clock of 5.70 GHz. The 7413 has a base clock of 2.65 GHz and a boost clock of 3.60 GHz. The 4584PX runs at a 1.55 GHz higher base clock and a 2.10 GHz higher boost clock.

Thermal design power (TDP) also differs: the 4584PX is rated at 120 W, while the 7413 is rated at 180 W. Despite the 7413 having more cores, it consumes more power at its rated TDP.

Memory support differs in both type and width. The 4584PX uses DDR5 with a dual-channel memory bus and a memory bandwidth of 83.2 GB/s. The 7413 uses DDR4 with an eight-channel memory bus and a memory bandwidth of 204.8 GB/s. The 7413's bandwidth is more than double that of the 4584PX.

PCIe capabilities differ as well. The 4584PX offers Gen 5 with 28 lanes, while the 7413 offers Gen 4 with 128 lanes. The 7413 provides far more lanes, suited for dense server configurations, while the 4584PX offers a newer generation but fewer lanes.

Other differences include the presence of integrated graphics on the 4584PX (Radeon Graphics) versus none on the 7413, and the part numbers: 100-000001481 for the 4584PX and 100-000000323100-100000323WOF for the 7413. Both have locked multipliers.

Head-to-Head Benchmarks

The most striking result in the head-to-head data is the PassMark single-thread test, where the 4584PX scores 3795 against 2400, a 58.1% advantage. This is the largest single delta across all recorded benchmarks. The same score appears under both PassMark test labels (single_thread and singlethread), confirming consistency.

In Cinebench tests, the 4584PX wins all six variants. The multi-core deltas are remarkably uniform: 19.7% in R15 (5193 versus 4338), 19.7% in R20 (21640 versus 18078), and 19.7% in R23 (51524 versus 43044). Single-core deltas are also uniform at 19.8% for R15 (733 versus 612) and R20 (3055 versus 2551), and 19.7% for R23 (7274 versus 6076). This consistency suggests a stable architectural advantage across workload types.

In PassMark extended instructions, the 4584PX leads by 17.7% (53774 versus 45696). In PassMark find prime numbers, it leads by 11.1% (441 versus 397). In PassMark random string sorting, the lead is 8.1% (87690 versus 81134). In PassMark multithread, the 4584PX scores 58117 against 50641, a 14.8% lead. In PassMark data compression, the lead narrows to 3.6% (741648 versus 715616). In PassMark floating point math, the 4584PX leads by only 2.2% (121460 versus 118881).

The 7413 wins three tests. Its largest win is in PassMark integer math, where it scores 215629 against 201919, a 6.4% advantage. In PassMark data encryption, it scores 48492 versus 45902, a 5.3% lead. In PassMark physics, it scores 4708 versus 4574, a 2.8% lead. These wins indicate that the 7413's higher core count and wider memory bus still provide tangible benefits in specific computational patterns.

Overall, the 4584PX wins 14 tests and the 7413 wins 3. The average benchmark scores reflect this overall trend: 83090 for the 4584PX versus 80041 for the 7413. The percentile rankings place both in the top 5% of all CPUs in the database, but the 4584PX sits one percentile higher. When weighed against nearest rivals, the 4584PX is essentially tied with the AMD EPYC 9135 (0.1% delta) and slightly behind the Intel Core Ultra 9 285K (0.9% delta). The 7413 sits within 1% of several Intel parts, including the Intel Xeon w5-2565X (0.8% higher) and Intel Core i9-14900KF (0.8% lower). The data indicates that the 4584PX is the stronger all-around performer, especially where single-thread speed and modern instruction efficiency matter, while the 7413 remains relevant for integer-heavy and encryption-heavy tasks.
