AMD EPYC 7702P vs AMD EPYC 9334 Comparison

# AMD EPYC 9334 vs AMD EPYC 7702P: Server Processor Analysis

The AMD EPYC 9334 and AMD EPYC 7702P are both high-core-count server processors, but they target different generations of AMD's data center roadmap. The 9334 belongs to the EPYC 9004 series (Zen 4, Genoa), while the 7702P is part of the EPYC 7002 series (Zen 2, Rome). Benchmark results from the database show a consistent edge for the 9334 across all tested Cinebench workloads.

Head-to-Head Benchmarks

The head-to-head comparison draws from six Cinebench runs (R15, R20, and R23, each in single-core and multi-core modes). The AMD EPYC 9334 wins all six comparisons.

In Cinebench R15 multi-core, the EPYC 9334 scores 5555 against 5272 for the EPYC 7702P, a 5.4% advantage. The single-core R15 result shows a similar gap: 784 versus 744, again a 5.4% delta in favor of the 9334.

Moving to Cinebench R20 multi-core, the 9334 posts 23146 points, with the 7702P at 21969, representing a 5.4% lead. The R20 single-core run gives 3267 for the 9334 versus 3101 for the 7702P, maintaining the same 5.4% differential.

The Cinebench R23 multi-core test shows the 9334 at 55110 versus 52308 for the 7702P, a 5.4% advantage. Finally, in R23 single-core, the 9334 scores 7780, while the 7702P reaches 7384, again a 5.4% difference.

Across all six results, the win margin is consistent at 5.4%, and the delta percentage in the database lists the AMD EPYC 9334 as the winner in every category. The average benchmark score for the 9334 is 15940, placing it in the 70th percentile of all CPUs in the database. The 7702P has an average score of 15130, sitting at the 69th percentile. The nearest rivals for the 9334 include the Intel Core Ultra 5 134U (0.2% slower), AMD Ryzen 5 40 (0.4% slower), AMD EPYC 75F3 (0.5% slower), and AMD EPYC 9354P (0.7% slower), all within a narrow performance band.

Architecture Differences

The two processors reflect two distinct architectures and platform generations. The EPYC 9334 is built on the Zen 4 architecture (codenamed Genoa) and uses a 5 nm process from TSMC. It integrates 32 cores and 64 threads. The EPYC 7702P uses the Zen 2 architecture (codenamed Rome), fabricated on a 7 nm node, also by TSMC. The 9334's transistor count is listed at 52,560 million across a die size of 4x72 mm², while the 7702P has 3,800 million transistors on a single 74 mm² die.

The 9334 has a three-level cache structure: 64 KB L1 per core, 1 MB L2 per core, and 128 MB shared L3. The 7702P also uses three cache levels: 96 KB L1 per core, 512 KB L2 per core, and 256 MB shared L3. This gives the 7702P a larger total L3 footprint, although the 9334's newer memory hierarchy still delivers the higher benchmark results in the database.

In terms of platform support, the 9334 uses AMD Socket SP5, while the 7702P uses AMD Socket SP3. Memory support differs: the 9334 supports DDR5 with a twelve-channel memory bus and 460.8 GB/s of bandwidth, while the 7702P supports DDR4 over an eight-channel bus at 204.8 GB/s. Both CPUs support ECC memory. PCIe connectivity is also a differentiator: the 9334 offers Gen 5 with 128 lanes (CPU only), whereas the 7702P provides Gen 4. Neither chip includes integrated graphics.

Where Each One Wins

Based solely on the recorded benchmarks, the AMD EPYC 9334 is the clear choice for any workload that leans heavily on multi-threaded, multi-core throughput. Its six head-to-head victories, all by 5.4%, make it the stronger part in Cinebench R15, R20, and R23, both single- and multi-core. For databases, rendering farms, or any application that is heavily parallel and scales with core count, the 9334 delivers more calculated results per unit of time.

The AMD EPYC 7702P still holds a niche where its architecture can be relevant. The 7702P has a larger L3 cache (256 MB vs 128 MB) and a lower 200W TDP compared to the 9334's 210W. In memory-bound workloads or those with working sets that repeatedly exceed the 9334's cache capacity, the 7702P's larger shared L3 may reduce the frequency of DRAM access. The 7702P also uses DDR4, which can matter in environments where the memory controller or platform remains on the older DDR4 infrastructure. For mixed-generation server fleets, the 7702P's Socket SP3 compatibility might be a simpler migration path than adopting the newer SP5 platform. The 9334's 12-channel memory bus provides a very high memory ceiling.

The EPYC 7702P has a lower base clock (2.00 GHz vs 2.70 GHz for the 9334) and a lower boost clock (3.35 GHz vs 3.90 GHz). For workloads with shorter bursts or where the software is not optimized for high core counts, the 9334's higher clock speeds and newer process node (5 nm vs 7 nm) can produce better latency and single-threaded behavior. The 9334's 2.70 GHz base clock and 3.90 GHz boost make it the better choice for lightly threaded or high-frequency-sensitive applications, even if the 7702P holds an advantage in raw core count.

In short: the EPYC 9334 is the overall benchmark leader and is the recommended option for modern multi-threaded workloads. The 7702P is the fallback for cache-heavy, DDR4-based platforms and for any budget that requires Socket SP3 compatibility.
