AMD EPYC 4344P vs AMD Ryzen 5 7500X3D Comparison

The AMD EPYC 4344P and AMD Ryzen 5 7500X3D are both 5 nm Zen 4 parts on the AM5 socket, but they target different corners of the market. The EPYC 4344P is a server/workstation chip with 8 cores and 16 threads, while the Ryzen 5 7500X3D is a desktop processor with 6 cores and 12 threads and a much larger L3 cache. Benchmark data shows a clear split: the EPYC dominates throughput-heavy workloads, while the Ryzen wins in specific latency-sensitive tests.

Head-to-Head Benchmarks

The head-to-head benchmark results are decisive in favor of the AMD EPYC 4344P, which wins 9 of the 11 recorded tests. The largest victory comes in `passmark_data_encryption`, where the EPYC scores 24476 against the Ryzen’s 15797, a delta of 54.9%. This is a massive gap, indicating the EPYC’s extra two cores and higher boost clock of 5.30 GHz provide a substantial advantage in cryptographic workloads. Similarly, in `passmark_integer_math`, the EPYC posts 105779 versus 70774, a 49.5% lead. This pattern repeats across most compute-heavy tasks.

The `passmark_multithread` test shows the EPYC at 33325, which is 33% higher than the Ryzen’s 25047. This aligns with the core count difference, as the EPYC’s 8 cores and 16 threads outnumber the Ryzen’s 6 cores and 12 threads. The `passmark_floating_point_math` result is also lopsided: 63309 for the EPYC versus 43594 for the Ryzen, a 45.2% advantage. Data compression and random string sorting follow suit, with the EPYC winning by 48.2% and 48.5%, respectively. Even in `passmark_extended_instructions`, the EPYC leads by 44.6%, scoring 29582 against 20455.

The Ryzen 5 7500X3D does not go down without a fight, however. It wins `passmark_find_prime_numbers` with a score of 221, which is 25.3% higher than the EPYC’s 165. This is a notable result, as prime number finding is often sensitive to cache size and latency. The Ryzen’s 96 MB of shared L3 cache likely drives this win. The other victory for the Ryzen is in `passmark_physics`, where it scores 2779 versus 1987, a 28.5% advantage. Physics simulations often benefit from lower latency and higher single-thread responsiveness, which the Ryzen’s 4.00 GHz base clock and larger cache provide.

Single-thread performance is nearly a dead heat. The EPYC 4344P scores 3526 in `passmark_single_thread`, edging out the Ryzen’s 3494 by just 0.9%. This is within the margin of error for most benchmarks, but it does show that the EPYC’s higher 5.30 GHz boost clock can compensate for the Ryzen’s architectural tweaks. The overall average benchmark score reflects this balance: the EPYC sits at 45122, which is 1.2% ahead of the Ryzen’s 44573, according to the nearestRivals data.

The Verdict

The data points to a clear choice based on workload. For server or workstation tasks that involve heavy data processing, encryption, or multi-threaded math, the AMD EPYC 4344P is the superior option. Its wins in `passmark_integer_math` (49.5% ahead), `passmark_floating_point_math` (45.2% ahead), and `passmark_multithread` (33% ahead) demonstrate a decisive advantage in throughput. The EPYC’s 8 cores and 16 threads, combined with a 5.30 GHz boost clock, make it the pick for anyone running parallel compute jobs.

For desktop users focused on gaming or latency-sensitive applications, the AMD Ryzen 5 7500X3D holds its own. Its wins in `passmark_find_prime_numbers` and `passmark_physics` suggest that the 96 MB of L3 cache provides a tangible benefit in workloads that rely on rapid data access. The Ryzen also matches the EPYC in single-thread performance within 0.9%, so it will not feel slower in everyday tasks. However, the EPYC’s overall average score is higher, and it wins 9 out of 11 benchmarks.

The choice comes down to the workload. If the priority is raw multi-core throughput for rendering, compression, or encryption, the EPYC 4344P is the winner. If the priority is cache-sensitive desktop responsiveness, the Ryzen 5 7500X3D is the more appropriate pick. The data does not suggest a universal winner; it suggests two specialized tools for different jobs.

Specification Differences

The two processors differ on several key specification points. The AMD EPYC 4344P has 8 cores and 16 threads, while the AMD Ryzen 5 7500X3D has 6 cores and 12 threads. The EPYC’s base clock is 3.80 GHz, which is lower than the Ryzen’s 4.00 GHz, but the EPYC’s boost clock is 5.30 GHz, significantly higher than the Ryzen’s 4.50 GHz. Both have a TDP of 65 W.

The cache configuration is a major differentiator. The EPYC 4344P has 32 MB of shared L3 cache, while the Ryzen 5 7500X3D has 96 MB of shared L3 cache. Both have 64 KB of L1 cache per core and 1 MB of L2 cache per core. The Ryzen’s larger L3 cache is its primary architectural advantage.

Memory support is identical: both support DDR5 with a dual-channel memory bus and 83.2 GB/s of memory bandwidth. Both also support ECC memory. PCIe lanes differ, with the EPYC 4344P offering Gen 5 with 28 lanes (CPU only) versus the Ryzen’s Gen 5 with 24 lanes (CPU only). Both have integrated Radeon Graphics.

The part numbers and release dates differ. The EPYC 4344P has part number 100-000001479 and was released on 2024-05-20. The Ryzen 5 7500X3D has part number 100-000001904 and was released on 2025-11-11. Neither has an unlocked multiplier. The market segments also differ, with the EPYC classified as Server/Workstation and the Ryzen as Desktop.

Architecture Differences

Both chips are built on the Zen 4 architecture with the Raphael codename, but they are packaged differently. The EPYC 4344P is part of the EPYC 4004 series, while the Ryzen 5 7500X3D is part of the 7000 series. Both are manufactured on a 5 nm process at TSMC, but the transistor counts differ significantly: the EPYC has 6,570 million transistors, while the Ryzen has 11,270 million. Despite this, both have the same die size of 71 mm².

The core configuration is the primary architectural split. The EPYC 4344P uses 8 cores and 16 threads, while the Ryzen 5 7500X3D uses 6 cores and 12 threads. This explains the EPYC’s dominance in multi-threaded benchmarks. However, the Ryzen’s L3 cache is three times larger: 96 MB versus 32 MB. This is the key reason for the Ryzen’s wins in cache-sensitive tests like `passmark_find_prime_numbers` and `passmark_physics`.

Both chips support DDR5 memory and have a dual-channel memory bus with 83.2 GB/s of bandwidth. Both also support ECC memory, which is notable for a desktop chip like the Ryzen. The integrated graphics are Radeon Graphics on both, though the EPYC is aimed at server/workstation use while the Ryzen is aimed at desktop use. The PCIe implementation differs, with the EPYC offering 28 lanes versus the Ryzen’s 24 lanes, both Gen 5. The higher lane count on the EPYC is consistent with its server-oriented positioning, allowing for more expansion devices.

The generations are labeled differently, with the EPYC listed as "EPYC (Zen 4 (Raphael))" and the Ryzen as "Ryzen 5 (Zen 4 (Raphael))". Both are production-active and use the AMD Socket AM5. The launch MSRP for the EPYC 4344P is $329, while the Ryzen 5 7500X3D has a launch MSRP of $269.
