AMD EPYC 8534P vs Intel Xeon 6747P Comparison

Head-to-Head Benchmarks

The benchmark data shows a dominant performance profile for the Intel Xeon 6747P, which wins 12 of the 14 recorded head-to-head comparisons. The most striking margin appears in the Cinebench multi-core tests, where the Intel part leads the AMD EPYC 8534P by a consistent 41.4% across Cinebench R15, R20, and R23. In Cinebench R23 multi-core, the Intel Xeon 6747P scores 86,432 against the AMD EPYC 8534P's 61,115, a gap that reflects a substantial advantage in sustained all-core rendering workloads.

The PassMark multi-thread test tells a similar story, with the Intel Xeon 6747P scoring 101,685 versus 71,900 for the AMD EPYC 8534P, again a 41.4% advantage. This consistency across multiple multi-threaded benchmarks suggests the Intel processor's throughput advantage is not workload-specific but rather a general property of its architecture and configuration.

The Intel Xeon 6747P also demonstrates a significant edge in single-thread performance. In the PassMark single-thread test, it scores 3,236 against 2,441 for the AMD EPYC 8534P, a 32.6% advantage. This is notable because the AMD part has a higher core count, yet the Intel chip delivers better per-thread performance, which matters for latency-sensitive server workloads and lightly threaded applications.

In the PassMark physics test, the Intel Xeon 6747P is categorically faster, scoring 13,398 against 3,667, a 265.4% advantage. The prime number finding test shows an even larger relative gap: 1,151 versus 278, a 314% difference in favor of Intel. These two results indicate that the Intel architecture is particularly strong in workloads involving sequential integer operations and physics simulation.

The floating-point math test also favors the Intel Xeon 6747P, which scores 365,904 versus 289,443 for the AMD EPYC 8534P, a 26.4% lead. Extended instruction throughput follows the same pattern, with Intel ahead by 26.3% (142,557 versus 112,860). Random string sorting, a memory-latency-sensitive workload, shows Intel ahead by 39.3% (180,382 versus 129,479).

The AMD EPYC 8534P does secure two wins. Its most decisive victory is in data encryption, where it scores 121,728 against 90,789 for the Intel Xeon 6747P, a 25.4% advantage. This suggests AMD's implementation handles cryptographic workloads more efficiently. The AMD part also wins in integer math, scoring 514,526 versus 468,518, an 8.9% lead. Data compression is nearly a tie, with the Intel Xeon 6747P ahead by just 2.3% (1,833,378 versus 1,791,742).

Looking at the broader database context, the Intel Xeon 6747P sits in the 99th percentile of all CPUs, while the AMD EPYC 8534P sits in the 98th percentile. The Intel part's average benchmark score is 238,263, which is 2.5% behind the AMD EPYC 9634, 5.3% behind the Intel Xeon 6980P, 9.4% ahead of the AMD EPYC 9455P, and 13.5% ahead of the Intel Xeon w9-3595X. The AMD EPYC 8534P's average score of 185,092 places it 1.3% ahead of the AMD Ryzen Threadripper PRO 9975WX, 1.4% behind the Intel Xeon 6740E, 2.9% ahead of the AMD EPYC 7763, and 4.3% behind the Intel Xeon 678X.

The Verdict

The data points to a clear performance hierarchy. The Intel Xeon 6747P is the faster processor in the vast majority of measured workloads. Its 41.4% lead in multi-core rendering, 32.6% lead in single-thread performance, and 314% lead in prime number finding make it the better choice for compute-heavy server and workstation tasks where raw throughput is the priority.

The AMD EPYC 8534P is not without merit. Its 25.4% advantage in data encryption and 8.9% lead in integer math indicate that specific workloads, particularly those involving cryptographic operations or integer-heavy processing, would run faster on the AMD chip. However, these are narrow niches within the broader benchmark suite.

For buyers who prioritize multi-threaded rendering, physics simulation, floating-point math, or single-thread responsiveness, the Intel Xeon 6747P is the data-supported choice. For buyers whose workloads are dominated by encryption or integer math, the AMD EPYC 8534P offers a measurable advantage in those specific areas. The Intel part also carries a launch MSRP of $6497, while the AMD part carries a launch MSRP of $4950.

Specification Differences

The two processors differ in nearly every core specification. The Intel Xeon 6747P has 48 cores and 96 threads, while the AMD EPYC 8534P has 64 cores and 128 threads. Base clocks are 2.70 GHz for Intel and 2.30 GHz for AMD; boost clocks are 3.90 GHz for Intel and 3.10 GHz for AMD. Thermal design power is 330 watts for Intel and 200 watts for AMD.

Memory support differs in channel count and bandwidth. The Intel Xeon 6747P uses an eight-channel DDR5 memory bus with 409.6 GB/s of bandwidth, while the AMD EPYC 8534P uses a six-channel DDR5 bus with 230.4 GB/s. Both support ECC memory.

PCIe connectivity also differs. The Intel part provides Gen 5 with 88 lanes (CPU only), while the AMD part provides Gen 5 with 96 lanes (CPU only).

Cache hierarchies are different in both size and allocation. The Intel Xeon 6747P has 112 KB of L1 cache per core, 2 MB of L2 cache per core, and 288 MB of shared L3 cache. The AMD EPYC 8534P has 64 KB of L1 per core, 1 MB of L2 per core, and 128 MB of shared L3.

Architecture Differences

The Intel Xeon 6747P is built on the Granite Rapids architecture, part of the Xeon 6 (Granite Rapids-SP) generation. It uses a 5 nm process node fabricated by Intel. The die size is listed as 2x 598 mm². The AMD EPYC 8534P is built on the Zen 4c architecture, part of the EPYC 8004 series with the Siena codename. It uses a 5 nm process node fabricated by TSMC. The AMD die consists of 4x 73 mm² chiplets, and the processor contains 35,500 million transistors.

The socket and platform are entirely different. The Intel Xeon 6747P uses Intel Socket 4710, while the AMD EPYC 8534P uses AMD Socket SP6. Both are server/workstation parts, both are currently active in production, and neither has an unlocked multiplier. The Intel part has no integrated graphics; the AMD part lists no integrated graphics either.

The release dates differ substantially. The AMD EPYC 8534P was released on 2023-09-17, while the Intel Xeon 6747P was released on 2025-02-23. The Intel part has a part number of SRVEZ, and the AMD part has a part number of 100-000000875.

Where Each One Wins

The Intel Xeon 6747P wins in 12 of the 14 head-to-head comparisons. Its largest advantages are in prime number finding (314%), physics simulation (265.4%), and the Cinebench multi-core suite (41.4% across all three tests). It also wins in random string sorting by 39.3%, single-thread performance by 32.6%, floating-point math by 26.4%, and extended instructions by 26.3%. Data compression is a narrow win at 2.3%.

The AMD EPYC 8534P wins in data encryption by 25.4% and integer math by 8.9%. These two wins define its use-case profile. Workloads that rely heavily on AES or other cryptographic primitives, as well as integer-heavy computation patterns, would see better performance on the AMD chip.

For a server or workstation deployment where the workload mix includes rendering, physics, floating-point math, or general single-threaded responsiveness, the Intel Xeon 6747P dominates. The recorded data shows no scenario outside of encryption and integer math where the AMD EPYC 8534P pulls ahead.

The AMD EPYC 8534P does offer more cores (64 versus 48) and more threads (128 versus 96), but the benchmark results show that core count alone does not translate into a throughput advantage in this comparison. The Intel Xeon 6747P's higher clocks, larger caches, and wider memory bus more than compensate for the core deficit in most tests.

The choice comes down to workload specialization. Encryption-centric or integer-math-centric environments should favor the AMD EPYC 8534P. Everything else in the measured data favors the Intel Xeon 6747P.
