Architecture Differences

The two CPUs are built on the same 5 nm process node, but by different foundries: Intel fabricates the Xeon 6740E, while TSMC fabricates the EPYC 8534P. Their architectural philosophies diverge sharply. The Intel Xeon 6740E uses Sierra Forest, a design that prioritizes core count and power efficiency over per-thread performance, with 96 cores and 96 threads — no simultaneous multithreading. Its cache hierarchy is module-based: 96 KB of L1 per core, 4 MB of L2 per module, and 96 MB of shared L3. The die size is listed as 578 mm², and the processor fits into Intel Socket 4710.

The AMD EPYC 8534P uses the Zen 4c architecture (codenamed Siena), a dense variant of Zen 4 that packs 64 cores into four chiplets, each with a die size of 73 mm², for a total of 35,500 million transistors. It supports 128 threads via SMT, with 64 KB of L1 per core, 1 MB of L2 per core, and a larger 128 MB shared L3 cache. The AMD chip uses AMD Socket SP6. Both processors support DDR5 memory and ECC, but the Intel part has an eight-channel memory bus versus the AMD’s six-channel, leading to the bandwidth difference noted earlier. Neither processor includes integrated graphics, and both are locked (multiplier not unlocked).

A key structural difference is the thread model: the Xeon’s 96 threads come from 96 physical cores, while the EPYC’s 128 threads come from 64 cores with two threads each. This impacts workloads that scale with physical cores versus those that benefit from extra threads. The AMD part’s larger L3 cache (128 MB vs 96 MB) and per-core L2 (1 MB vs 4 MB per module, where a module may contain multiple cores) suggest different memory-access patterns, with AMD favoring per-core cache locality.

Head-to-Head Benchmarks

Across the 17 benchmark comparisons in the data, the Intel Xeon 6740E wins 12 and the AMD EPYC 8534P wins 5. The Intel victories are often lopsided, while the AMD wins are concentrated in a few specific areas.

The Xeon’s biggest wins come in multi-threaded and physics-heavy tests. In PassMark physics, the Intel part scores 7608 versus 3667 for the EPYC, a massive 107.5% advantage.

In Cinebench tests, the Intel part consistently leads by 5.9% across R15, R20, and R23 multicore, with scores like 64741 versus 61115 in R23 multicore. Single-core Cinebench results are similar, with Intel ahead by 6% in R15 (921 vs 869) and 5.9% in R23 (9140 vs 8628). PassMark data encryption also goes to Intel, with a 12.6% margin (137106 vs 121728), and floating point math favors Intel by 6.9% (309333 vs 289443). PassMark multithread shows Intel ahead by 5.9% (76167 vs 71900).

The AMD EPYC 8534P counterattacks in integer-heavy and instruction-extensive workloads. Its biggest win is PassMark extended instructions, where it scores 112860 versus 78968 for Intel — a 30% advantage. PassMark integer math goes to AMD by 11.1% (514526 vs 457614). The EPYC also wins PassMark single-thread tests by 18.2% (2441 vs 1997), and it narrowly edges Intel in PassMark data compression with 1791742 versus 1786845, a 0.3% difference.

The pattern is clear: Intel dominates in physics, prime-number finding, string sorting, encryption, and all Cinebench rendering tests, while AMD takes the lead in integer math, extended instruction sets, single-threaded PassMark, and data compression. The overall average benchmark scores reflect this, with Intel at 187718 and AMD at 185092, placing the Xeon 1.4% ahead of the EPYC.

Specification Differences

The two processors differ across nearly every core specification. The Intel Xeon 6740E has 96 cores and 96 threads, while the AMD EPYC 8534P has 64 cores and 128 threads. Base clocks are close: 2.40 GHz for Intel versus 2.30 GHz for AMD, with boost clocks of 3.20 GHz and 3.10 GHz respectively. TDP differs at 250 for Intel and 200 for AMD, a 50-point gap.

Cache configurations are notably different. The Intel part has 96 KB of L1 per core, 4 MB of L2 per module, and 96 MB of shared L3. The AMD part has 64 KB of L1 per core, 1 MB of L2 per core, and 128 MB of shared L3. This gives AMD more total L3, while Intel’s L2 is organized per module rather than per core.

Memory channels and bandwidth split the two: Intel uses eight-channel DDR5 with 409.6 GB/s, while AMD uses six-channel DDR5 with 230.4 GB/s. Both support ECC memory. PCIe lanes favor AMD, with Gen 5 96 lanes versus Gen 5 88 lanes for Intel. The sockets are different (Intel Socket 4710 vs AMD Socket SP6), and the part numbers are SRPFV for Intel and 100-000000875 for AMD. Release dates differ, with Intel’s part releasing after AMD’s, and the launch MSRPs are $5265 for Intel and $4950 for AMD. Both are locked multipliers and lack integrated graphics.

The Verdict

The benchmark data shows the Intel Xeon 6740E as the stronger all-around performer, with a 1.4% higher average benchmark score than the AMD EPYC 8534P. Intel wins 12 of 17 head-to-head comparisons, including all Cinebench multicore and single-core tests, which are representative of rendering and general multi-threaded workloads. The Xeon’s wins in PassMark physics (107.5% ahead) and find prime numbers (89.2% ahead) are dramatic, suggesting a significant advantage in simulation and number-crunching tasks. Its higher memory bandwidth (409.6 GB/s vs 230.4 GB/s) and eight-channel support further reinforce its suitability for memory-intensive server applications.

The AMD EPYC 8534P, however, is not without merit. It wins decisively in PassMark extended instructions (30% ahead) and integer math (11.1% ahead), pointing to strength in encryption, data processing, and instruction-heavy code. Its single-thread PassMark score is 18.2% better, which may benefit lightly threaded applications. The EPYC also has more PCIe lanes (96 vs 88) and a larger L3 cache (128 MB vs 96 MB), plus a lower TDP of 200 versus 250, making it more power-efficient in the data. Its 128 threads versus 96 may help in highly threaded workloads that scale beyond core count.

The choice depends on workload priority. For users running Cinebench-style rendering, physics simulation, or memory-bandwidth-hungry tasks, the Intel Xeon 6740E is the clear pick — its margins in these areas are substantial. For those focused on integer-heavy processing, extended instruction sets, or single-threaded PassMark performance, the AMD EPYC 8534P offers a compelling alternative, especially with its lower TDP and additional PCIe lanes. Neither part is universally better; the data supports Intel for raw multi-core throughput and AMD for specific computational patterns.

Where Each One Wins

The Intel Xeon 6740E wins in the following benchmark categories: all three Cinebench multicore tests (R15, R20, R23) with 5.9% margins, all three Cinebench single-core tests with 5.9-6% margins, PassMark data encryption (12.6% ahead), PassMark find prime numbers (89.2% ahead), PassMark floating point math (6.9% ahead), PassMark multithread (5.9% ahead), PassMark physics (107.5% ahead), and PassMark random string sorting (70.4% ahead). This makes it the better choice for rendering, physics simulation, encryption workloads, floating-point calculations, and any task that benefits from high memory bandwidth (409.6 GB/s) and eight-channel memory support.

The AMD EPYC 8534P wins in PassMark data compression (0.3% ahead), PassMark extended instructions (30% ahead), PassMark integer math (11.1% ahead), and PassMark single-thread (18.2% ahead). Its higher single-thread PassMark score (2441 vs 1997) and integer math advantage make it suitable for tasks like data compression, integer-heavy database operations, and instruction-set-specific code. The 128-thread count, 128 MB L3 cache, and 96 PCIe lanes add to its appeal for high-throughput I/O scenarios, while its lower TDP of 200 makes it the more power-conscious option. For users who prioritize these specific workloads, the EPYC 8534P is the winner, despite losing the overall average benchmark score to the Xeon 6740E.
