AMD EPYC 7C13 vs Intel Xeon 6737P Comparison

Architecture Differences

The AMD EPYC 7C13 and Intel Xeon 6737P represent fundamentally different design philosophies. The EPYC 7C13 uses AMD's Zen 3 architecture, codenamed Milan, built on a 7nm process at TSMC. The chip is assembled from eight compute dies, each measuring 81 mm², with a combined transistor count of 33,200 million. In contrast, the Xeon 6737P uses Intel's Granite Rapids architecture, built on a 5nm process at Intel's own foundry, with a monolithic die size of 598 mm².

The core count disparity is significant. The AMD part packs 64 cores with 128 threads, while the Intel part offers 32 cores with 64 threads. This 2:1 core ratio is the single most important architectural differentiator. The cache hierarchies also diverge sharply. Each Zen 3 core gets 64 KB of L1 and 512 KB of L2, with a large 256 MB shared L3 pool. The Granite Rapids core, by contrast, has 112 KB of L1 and 2 MB of L2 per core, with a smaller 144 MB shared L3. Intel's per-core L2 advantage is substantial, but AMD's total L3 capacity is nearly double.

Memory support separates the generations. The EPYC 7C13 runs DDR4 across an eight-channel bus, delivering 204.8 GB/s of bandwidth. The Xeon 6737P moves to DDR5 across the same eight-channel configuration, doubling theoretical bandwidth to 409.6 GB/s. PCIe connectivity also differs: AMD provides Gen 4 with 128 lanes, while Intel provides Gen 5 with 88 lanes. The Intel part has no integrated graphics, consistent with server positioning.

The process node difference (7nm vs 5nm) partially explains why Intel can hit higher clocks with fewer cores. The EPYC 7C13 has a base clock of 2.00 GHz and a boost of 3.68 GHz, while the Xeon 6737P starts at 2.90 GHz and boosts to 4.00 GHz. Thermal design power reflects this: the AMD part is rated at 225W, the Intel at 270W. Both are active production parts, and both target the server/workstation segment.

Head-to-Head Benchmarks

The benchmark data shows a clear split: Intel wins the majority of tests (11 of 16), but AMD wins the largest individual margins. Starting with the Cinebench suite, the Xeon 6737P takes every multi-core and single-core test. In Cinebench R15 multi-core, it scores 6822 against 6539, a 4.1% lead. Single-core R15 shows 963 versus 923, a 4.2% edge. The R20 multi-core result is 28428 versus 27246, again 4.2% ahead. R20 single-core is 4013 versus 3846, a 4.2% margin. The R23 multi-core result repeats the pattern: 67688 versus 64873, a 4.2% lead. These consistent Cinebench margins indicate the Intel part's higher clock speeds and per-core efficiency offset its core deficit in this workload.

PassMark multithread follows the same trend: 79634 versus 76322, a 4.2% Intel win. PassMark single-thread shows a larger gap: 3048 versus 2618, a 14.1% Intel advantage. The same single-thread result appears for the duplicate "singlethread" test. PassMark physics delivers the biggest Intel margin of all: 9362 versus 4904, a 47.6% lead. This physics test heavily favors the Intel architecture's per-core throughput. PassMark extended instructions goes to Intel at 105453 versus 85034, a 19.4% edge. PassMark find prime numbers also favors Intel: 697 versus 539, a 22.7% lead.

AMD's wins are concentrated in specific workloads. The largest is data encryption: 114769 versus 65615, a massive 74.9% advantage. This reflects the EPYC's 64-core parallelism and possibly the Zen 3 encryption instruction implementation. Data compression also goes strongly to AMD: 1562251 versus 1157255, a 35% lead. Integer math shows a 48.9% AMD advantage: 492554 versus 330756. Floating-point math is closer, with AMD winning 266846 versus 258811, a 3.1% margin. Random string sorting is nearly tied: 131361 versus 129510, a 1.4% AMD edge.

The wins distribution (5 for AMD, 11 for Intel) understates AMD's average advantage because AMD's wins are in heavy-throughput workloads with large absolute score gaps. The EPYC 7C13's average benchmark score of 167,788 versus Intel's 140,694 reflects this, putting AMD roughly 19% higher overall.

Where Each One Wins

The AMD EPYC 7C13 is the clear choice for workloads that scale with core count and involve data transformation. Its 74.9% lead in data encryption makes it the preferred option for security-focused applications, database encryption, and cryptographic workloads. The 35% advantage in data compression suits backup systems, log processing, and storage workloads. Integer math, where AMD leads by 48.9%, covers many general compute tasks, including financial modeling, scientific computing, and code compilation. The floating-point win, though narrower at 3.1%, still favors AMD for simulation and certain engineering applications. The 98th percentile ranking across all CPUs, tied with the Intel part, confirms both are top-tier parts.

The Intel Xeon 6737P wins where per-core performance and clock speed matter most. Its 14.1% single-thread advantage makes it better for lightly threaded applications, legacy software, and workloads with strict latency requirements. The 47.6% physics score lead indicates strong performance in game physics simulation, which is relevant for cloud gaming and interactive workloads. The 19.4% extended instructions win suggests better support for vectorized code paths. The 22.7% find-prime-numbers edge points to better performance in integer-heavy sequential algorithms. The consistent 4.2% Cinebench margins across all versions indicate that the Intel part is more efficient in rendering tasks that respond well to high clocks, even at half the core count.

For memory-bound workloads, the Xeon's DDR5 support with 409.6 GB/s bandwidth gives it a theoretical advantage. The EPYC's DDR4 implementation at 204.8 GB/s is half the bandwidth. However, the benchmark data does not show bandwidth-sensitive tests among the recorded results. The PCIe Gen 5 lanes on the Intel part support newer accelerators, while the AMD part's 128 Gen 4 lanes offer more total connectivity.

The 270W TDP of the Xeon versus 225W for the EPYC means the AMD part delivers more average throughput per watt in its winning workloads. The Intel part's higher TDP buys clock speed. For power-constrained deployments with heavy parallel workloads, the EPYC 7C13's 64 cores at lower clocks are more efficient. For latency-sensitive or lightly threaded environments, the Xeon 6737P's higher clocks deliver better response times.

Both processors sit at the 98th percentile of all CPUs in the database. The choice depends entirely on workload profile: AMD for massive thread counts and data-heavy operations, Intel for clock-driven single-thread and physics-bound tasks. The data shows no universal winner, only distinct domain advantages.
