Intel Xeon 6737P vs Intel Xeon 674X Comparison

Head-to-Head Benchmarks

The benchmark data for the Intel Xeon 674X and Intel Xeon 6737P reveals a clear split: the 674X dominates in single-threaded and Cinebench workloads, while the 6737P counters in several Passmark sub-tests. Across the 16 head-to-head comparisons, the 674X takes 9 wins and the 6737P takes 7, but the margins tell a more nuanced story.

The most decisive victory for the Intel Xeon 674X comes in PassMark single-thread performance, where it scores 3933 versus 3048 for the 6737P, a 29% advantage. This is the largest delta in either direction across the entire comparison. The 674X also posts a 5.7% lead in every Cinebench test—R15 multi-core (7213 vs 6822), R15 single-core (1018 vs 963), R20 multi-core (30057 vs 28428), R20 single-core (4243 vs 4013), and R23 multi-core (71566 vs 67688). The consistency of that 5.7% delta across all five Cinebench workloads suggests a structural advantage rather than a workload-specific quirk.

In PassMark multi-thread, the 674X again leads with 84196 versus 79634, another 5.7% margin. Data compression follows the same pattern: 1236272 for the 674X versus 1157255 for the 6737P, a 6.8% edge.

The Intel Xeon 6737P fights back most strongly in PassMark physics, scoring 9362 versus 7586, a 19% advantage that represents its largest win. It also leads in extended instructions (105453 vs 97373, a 7.7% edge), integer math (330756 vs 308968, 6.6%), data encryption (65615 vs 61195, 6.7%), and floating-point math (258811 vs 243877, 5.8%). Two additional wins are narrower: find prime numbers (697 vs 693, 0.6%) and random string sorting (129510 vs 127529, 1.5%).

The average benchmark scores reflect this balance. The 674X averages 143103 across all tests, while the 6737P averages 140694. The 674X sits at 98th percentile among all CPUs, and interestingly, the 6737P also occupies the 98th percentile. The 6737P's nearest rival is the 674X itself, with a delta of -1.7% in average score.

Architecture Differences

Both processors are built on Intel's Granite Rapids architecture and use a 5 nm process node from Intel's own foundry. However, they belong to different product generations within that architecture. The Intel Xeon 674X is part of the Xeon 600 series (Granite Rapids-WS), while the Intel Xeon 6737P belongs to the Xeon 6 series (Granite Rapids-SP).

The die layout differs notably. The 674X uses a dual-die configuration with a combined size of 2x 598 mm², while the 6737P uses a single die measuring 598 mm². This means the 674X effectively doubles the silicon area, which helps explain its higher core clock speeds despite having fewer cores.

Core counts diverge: the 674X has 28 cores and 56 threads, while the 6737P has 32 cores and 64 threads. The 6737P thus offers 4 more physical cores and 8 more threads. Cache per core is identical at 112 KB L1 and 2 MB L2, and both share 144 MB of L3 cache, so the 6737P's extra cores do not come at the expense of shared cache.

PCIe lane counts differ substantially. The 674X provides Gen 5 with 128 lanes (CPU only), while the 6737P offers Gen 5 with 88 lanes (CPU only). That 40-lane difference is significant for systems needing maximum I/O expansion.

Memory support is equivalent: both use DDR5 with an eight-channel memory bus and 409.6 GB/s of bandwidth, and both support ECC memory. Neither has integrated graphics.

The 674X has an unlocked multiplier, whereas the 6737P does not. This makes the 674X the more flexible option for overclocking, though both are server/workstation parts where that may matter less.

Where Each One Wins

The Intel Xeon 674X is the clear choice for workloads that depend on single-thread speed and Cinebench-style rendering. Its 29% lead in PassMark single-thread performance is the standout metric. The 5.7% advantage across all Cinebench tests—R15, R20, and R23, both single and multi-core—suggests strong performance in content creation and 3D rendering tasks. Its 6.8% lead in data compression also makes it the better option for archive and storage-heavy workloads. The 674X's 128 PCIe lanes provide substantially more I/O headroom for systems with many GPUs, NVMe drives, or network cards.

The Intel Xeon 6737P wins in several compute-heavy PassMark sub-tests that likely benefit from its additional 4 cores. The 19% lead in physics is the most dramatic, pointing to simulation and physics-based workloads. It also leads in extended instructions (7.7%), integer math (6.6%), data encryption (6.7%), and floating-point math (5.8%). These results indicate that the 6737P handles general-purpose compute, cryptographic operations, and scientific calculations more efficiently. Its 88 PCIe lanes are still substantial for most server configurations.

The 6737P's wins in find prime numbers (0.6%) and random string sorting (1.5%) are marginal, but they contribute to a broader pattern: the 6737P excels in diverse, math-heavy Passmark sub-tests, while the 674X excels in the more focused Cinebench and single-thread categories.

The Verdict

The data presents a clear trade-off between the two processors. The Intel Xeon 674X is the superior choice for users who prioritize single-thread performance, rendering workloads, and I/O expansion. Its 29% single-thread lead and consistent 5.7% Cinebench advantage make it the stronger pick for workstation tasks like 3D rendering, video editing, and any software that relies heavily on clock speed. The 128 PCIe lanes further cement its position for high-density I/O configurations.

The Intel Xeon 6737P is the better option for multi-threaded, compute-diverse workloads where core count matters more than clock speed. Its 32 cores versus 28, combined with wins in physics, integer math, floating-point math, and encryption, make it suitable for scientific computation, data processing pipelines, and cryptographic workloads. The 19% physics advantage is particularly notable for simulation-heavy applications.

For buyers choosing between these two parts, the decision hinges on workload profile rather than overall performance, since both sit at the 98th percentile. The 674X wins the average benchmark score battle (143103 vs 140694) and offers better single-thread and rendering performance. The 6737P counters with more cores and wins in seven sub-tests, including several with double-digit margins. Neither is a universal winner; each excels in distinct domains, and the correct pick depends entirely on whether the primary workloads resemble Cinebench rendering or Passmark's diverse compute suite.
