AMD Ryzen 9 PRO 9965 vs Intel Xeon 6737P Comparison

The AMD Ryzen 9 PRO 9965 and Intel Xeon 6737P are both 98th-percentile server/workstation processors, yet they represent fundamentally different approaches to throughput. The data shows a clear split: the Intel part dominates heavily threaded workloads, while the AMD chip holds a decisive edge in single-thread performance. The following analysis breaks down where each processor excels and which tasks favor one architecture over the other.

Head-to-Head Benchmarks

The Intel Xeon 6737P wins nine of the eleven shared benchmark comparisons, and its victories are not marginal. In the PassMark physics test, the Xeon scores 9362 against the Ryzen’s 3256, a 65.2% advantage—the largest gap in the entire dataset. This test likely stresses raw compute throughput, and the Xeon’s 32 cores versus 16 cores explains the magnitude of the difference. Similarly, in prime number finding, the Xeon posts 697 versus 364, a 47.8% lead, again reflecting a workload that scales with core count.

The Intel part also wins in floating-point math, scoring 258811 against the AMD’s 160746, a 37.9% delta. Extended instructions favor Intel by 32.5%, with scores of 105453 and 71210 respectively. Data encryption shows a 31.5% gap (65615 vs 44920), and data compression follows with a 21.5% difference (1157255 vs 908293). Integer math sees Intel ahead by 26.4% (330756 vs 243280). Even in multithreaded performance, a category where AMD’s 16-core/32-thread part is competitive, the Xeon leads by 16.3%, scoring 79634 versus 66655. Random string sorting rounds out Intel’s wins with a 26.7% advantage (129510 vs 94915).

The AMD Ryzen 9 PRO 9965’s only wins come in the two single-thread tests—which are identical results listed under different names. In both, the Ryzen scores 4682 against the Xeon’s 3048, a 53.6% lead. This is a massive single-thread advantage, reflecting the Ryzen’s 5.50 GHz boost clock versus the Xeon’s 4.00 GHz. The data suggests that any workload that cannot utilize more than a few cores will run dramatically faster on the AMD part.

Architecture Differences

The two processors come from different foundries and node sizes. AMD uses a 4 nm process at TSMC, while Intel uses a 5 nm process at its own fabs. The Ryzen is built on the Zen 5 architecture (codenamed Granite Ridge) from the 9000 series, whereas the Xeon uses the Granite Rapids architecture, part of the Xeon 6 generation. The Intel die is 598 mm², while AMD’s is composed of two 70.6 mm² dies, totaling 141.2 mm². AMD lists 16,630 million transistors; Intel does not provide a figure.

Core configurations differ sharply. The Ryzen has 16 cores and 32 threads, while the Xeon doubles that with 32 cores and 64 threads. Cache hierarchies also diverge: AMD provides 80 KB L1 per core and 1 MB L2 per core, with a 64 MB L3 pool. Intel offers 112 KB L1 per core and 2 MB L2 per core, with a larger 144 MB shared L3. That extra cache likely helps the Xeon in data-heavy workloads like compression and sorting.

Memory architecture is another major split. Both support DDR5 and ECC memory, but the Xeon uses an eight-channel bus with 409.6 GB/s bandwidth, compared to the Ryzen’s dual-channel 89.6 GB/s. That is a 4.6x difference in theoretical memory bandwidth, which explains the Xeon’s dominance in memory-intensive tests. PCIe connectivity also favors Intel: the Xeon provides 88 Gen 5 lanes, while the Ryzen offers 24. The Xeon has no integrated graphics; the Ryzen includes Radeon Graphics. Sockets differ as well—AMD uses Socket AM5, Intel uses Socket 4710. The Intel part carries a launch MSRP of $4995; the AMD listing has no MSRP field.

Where Each One Wins

The Intel Xeon 6737P is the clear choice for massively parallel, memory-bandwidth-hungry workloads. The 65.2% physics score advantage and 47.8% prime number lead indicate that compute-heavy scientific simulations or financial modeling would run substantially faster on Intel. The 409.6 GB/s memory bandwidth versus 89.6 GB/s suggests that any task involving large datasets—database queries, data compression, or encryption—will benefit from the Xeon. Its 32 cores and 64 threads provide the raw parallelism needed for rendering, virtualization, or multi-tenant server environments. The 144 MB L3 cache further supports workloads with large working sets.

The AMD Ryzen 9 PRO 9965 wins in scenarios where clock speed matters more than core count. Its 53.6% single-thread advantage means that legacy software, single-threaded applications, or tasks with serial bottlenecks will run dramatically faster. The 5.50 GHz boost clock is a full 1.5 GHz higher than the Xeon’s 4.00 GHz. This makes the Ryzen suitable for workstation tasks like interactive design, code compilation with limited parallelism, or any real-time application where latency per instruction is critical. The integrated Radeon Graphics also provides a display output, which is absent on the Intel part, making the AMD chip easier to deploy in a standalone workstation without a discrete GPU.

The Verdict

Based strictly on benchmark results, the Intel Xeon 6737P is the superior processor for heavily threaded server workloads. It wins 9 of 11 comparisons, with margins ranging from 16.3% (multithread) to 65.2% (physics). The 32-core/64-thread configuration combined with eight-channel memory and 144 MB L3 cache delivers consistent, large advantages in every multi-core test. For a server processing compression, encryption, or floating-point math, the data unambiguously favors Intel. The Xeon's nearest rivals include the Intel Xeon 674X (1.7% faster on average) and the AMD Ryzen 9 PRO 9965X3D (2.1% faster), placing it in a competitive field, but its head-to-head here is decisive.

The AMD Ryzen 9 PRO 9965 is the pick for single-thread-bound applications. Its 53.6% single-thread lead is the largest margin in any test, and its 4.30 GHz base clock (versus 2.90 GHz) ensures strong performance even without boost. The data does not support using this chip for multi-core throughput—it trails by double digits in nearly every parallel test. However, for a workstation running software that cannot scale beyond a few cores, the Ryzen’s speed per thread is unmatched. Its nearest rival, the AMD EPYC 7643P, is only 0.6% slower on average, and the Intel Xeon w9-3575X is 1% slower, showing that the Ryzen sits at the top of its performance tier for its strengths.
