Architecture Differences

The AMD EPYC 8434P is built on the Zen 4c architecture with the codename Siena, manufactured on a 5 nm process by TSMC. It uses 35,500 million transistors across a die size of 4x 73 mm². The Intel Xeon 6732P uses the Granite Rapids architecture, also on a 5 nm process but fabricated by Intel, with no transistor or die size data available in the provided information.

Cache hierarchies differ significantly between the two. The AMD EPYC 8434P has 64 KB of L1 cache per core, 1 MB of L2 per core, and 128 MB of shared L3 cache. The Intel Xeon 6732P has 112 KB of L1 per core, 2 MB of L2 per core, and 144 MB of shared L3 cache. Intel's per-core cache allocations are larger, while both share substantial L3 pools.

Memory architecture is a major differentiator. The AMD part uses a six-channel DDR5 memory bus with 230.4 GB/s bandwidth, while Intel uses an eight-channel DDR5 bus with 409.6 GB/s bandwidth. Both support ECC memory. PCIe connectivity also differs: AMD provides Gen 5 with 96 lanes (CPU only), while Intel provides Gen 5 with 136 lanes (CPU only).

The socket situation separates the platforms entirely. AMD uses Socket SP6, while Intel uses Socket 4710. The AMD part has a 200 W TDP, while the Intel part draws 350 W. Both are active production server/workstation parts with locked multipliers. The AMD EPYC 8434P launched on 2023-09-17, while the Intel Xeon 6732P launched on 2025-05-21.

The Verdict

The data points to a clear but workload-dependent choice. For general multi-threaded rendering and compute, the Intel Xeon 6732P is the stronger performer, winning Cinebench R15, R20, and R23 multi-core tests by a consistent 11.2% margin. Its 4.10 GHz boost clock and 409.6 GB/s memory bandwidth give it a decisive edge in floating-point math, physics simulation, and single-threaded tasks.

However, the AMD EPYC 8434P dominates in security and data processing workloads. Its 52.3% lead in data encryption and 15.2% lead in integer math make it the better choice for cryptographic operations and integer-heavy database workloads. The AMD part also leads in data compression by 5.5%.

For buyers prioritizing raw core count, the AMD part offers 48 cores versus Intel's 32, which may matter for highly parallel workloads that scale beyond 32 cores. Yet the benchmark data shows Intel's higher clocks and memory bandwidth often compensate for the core deficit in measured tests.

The Intel Xeon 6732P wins 14 of 17 head-to-head benchmarks, including all Cinebench tests, Passmark multithread, physics, floating-point math, and single-thread tests. The AMD EPYC 8434P wins only three: data encryption, integer math, and data compression. Based on the data, Intel is the default pick for most workloads, with AMD being the specialized choice for encryption and integer-heavy tasks.

Head-to-Head Benchmarks

The Intel Xeon 6732P demonstrates a consistent advantage across Cinebench workloads. In Cinebench R15 multi-core, Intel scores 6,412 versus AMD's 5,696, a gap of 11.2%. The same margin appears in R20 multi-core (26,720 vs 23,736) and R23 multi-core (63,621 vs 56,516). Single-core Cinebench results follow the same pattern: Intel leads by 11.2% in R15 (905 vs 804), R20 (3,772 vs 3,350), and R23 (8,981 vs 7,978). This consistency suggests a fundamental performance advantage in render-type workloads.

Passmark multithread results also favor Intel, with a score of 74,849 versus AMD's 66,490, again an 11.2% margin. Physics simulation shows an even larger Intel advantage: 8,109 versus 4,036, a 50.2% lead. Floating-point math goes to Intel at 261,703 versus 215,669, a 17.6% difference. Extended instructions favor Intel by 19.2% (106,697 vs 86,189). Random string sorting shows a narrower Intel win at 133,467 versus 125,932, a 5.6% margin. Single-thread Passmark is close, with Intel at 2,506 versus AMD's 2,448, a 2.3% advantage.

The AMD EPYC 8434P's wins are concentrated but substantial. Data encryption shows AMD at 97,254 versus Intel's 63,848, a 52.3% advantage, the largest delta in either direction across all benchmarks. Integer math goes to AMD at 385,290 versus 334,340, a 15.2% lead. Data compression is closer, with AMD at 1,412,835 versus Intel's 1,339,480, a 5.5% margin. Prime number finding is a notable Intel victory at 628 versus 298, a 52.5% lead, matching the scale of AMD's encryption win.

Where Each One Wins

The Intel Xeon 6732P wins in every Cinebench test, both single and multi-core, across R15, R20, and R23. This makes it the clear choice for 3D rendering, video encoding, and other workloads that rely on these benchmark patterns. Its physics simulation score of 8,109 versus AMD's 4,036 suggests a major advantage in simulation and physical modeling tasks. Floating-point math performance, winning 261,703 to 215,669, positions Intel well for scientific computing and engineering simulations.

The Intel part also wins in extended instructions, random string sorting, and the Passmark multithread test, indicating broad strength in general-purpose server workloads. Its single-thread advantage, while modest at 2.3%, combined with the 4.10 GHz boost clock, makes it better for lightly threaded applications.

The AMD EPYC 8434P wins specifically in data encryption with a massive 52.3% margin, making it the superior choice for VPN gateways, SSL termination, database encryption, and other cryptographic workloads. Its integer math advantage of 15.2% points to strength in database operations, financial calculations, and other integer-heavy processing. The data compression win of 5.5% suggests a slight edge in storage-related and archival workloads.

With 48 cores versus Intel's 32, the AMD part also offers more raw parallelism for workloads that scale beyond what benchmarks show. However, the data shows Intel's architecture compensates for this core deficit in most measured tests. For buyers with encryption-heavy or integer-intensive workloads, the AMD EPYC 8434P is the data-backed choice. For everything else in the benchmark suite, the Intel Xeon 6732P demonstrates superior measured performance.
