AMD EPYC 9375F vs Intel Xeon w9-3575X Comparison

The AMD EPYC 9375F and Intel Xeon w9-3575X are both high-end server and workstation processors, but the benchmark data reveals they have very different performance profiles. The EPYC 9375F, built on the Zen 5 architecture, consistently outperforms the Xeon w9-3575X in the vast majority of tests, despite the Intel chip having 44 cores compared to the AMD chip's 32 cores. The data suggests a fundamental difference in design philosophy, with AMD focusing on high clock speeds and efficient core performance, while Intel relies on a higher core count to drive throughput.

Head-to-Head Benchmarks

The most striking result in the head-to-head comparison is the PassMark find prime numbers test, where the AMD EPYC 9375F scores 1397 against the Intel Xeon w9-3575X's 687. This is a massive 103.3% advantage for the AMD chip, indicating a substantial lead in a workload that is sensitive to both integer performance and memory latency. This is not a marginal win; it is a complete dominance in this specific test.

Across the Cinebench suite, the AMD EPYC 9375F shows a consistent 14.9% advantage in every single test. In Cinebench R23 multicore, the AMD chip scores 81402 compared to the Intel chip's 70837. The same 14.9% delta appears in both single-core and multi-core tests for R15, R20, and R23, showing that the AMD's architectural efficiency provides a uniform performance uplift regardless of the workload's thread count.

The PassMark integer math test shows another significant AMD victory, with a score of 387901 versus 298224, a 30.1% difference. This is a major win for the EPYC 9375F in a core compute task. The PassMark physics test also shows a large 31.9% advantage for AMD, with scores of 9019 and 6836 respectively, suggesting the AMD chip handles physics simulations with far greater efficiency.

In data-heavy tasks, the AMD chip continues its winning streak. The data compression test shows a 22.7% lead, with scores of 1496149 and 1219584. The data encryption test shows an 18.3% advantage, and the random string sorting test shows a 19.6% advantage. The extended instructions test shows a 16.8% lead, and the multithread test shows a 14.9% lead. Even in the single-thread tests, the AMD EPYC 9375F wins, though by a smaller margin of 2.5%, with scores of 3762 and 3672.

The Intel Xeon w9-3575X secures only one victory in the entire head-to-head comparison: the PassMark floating point math test. Here, the Intel chip scores 273398 against the AMD's 260392, a 4.8% advantage. This is a notable win for Intel, suggesting that its architecture has a specific strength in floating-point calculations that the AMD chip does not match.

The overall count is decisive: the AMD EPYC 9375F wins 15 out of 16 head-to-head benchmarks, while the Intel Xeon w9-3575X wins only one. This is not a close contest; the data clearly shows the AMD chip as the superior performer in the vast majority of tested workloads.

Architecture Differences

The two processors are built on fundamentally different architectures. The AMD EPYC 9375F is based on the Zen 5 architecture, codenamed Turin, and is part of the EPYC 9005 series. It is manufactured on a 4 nm process by TSMC, featuring 66,520 million transistors across a multi-chiplet design with 8 dies, each measuring 70.6 mm². In contrast, the Intel Xeon w9-3575X is built on the Sapphire Rapids architecture and is part of the Xeon W generation. It uses a 10 nm process from Intel and features a larger die design of 4x 477 mm².

The core configurations differ significantly. The AMD EPYC 9375F has 32 cores and 64 threads, while the Intel Xeon w9-3575X has 44 cores and 88 threads. Despite having fewer cores, the AMD chip manages to win most benchmarks, which points to a significant per-core performance advantage. The base clock speeds highlight this difference: the AMD chip runs at 3.85 GHz, while the Intel chip runs at 2.20 GHz. Both chips have the same boost clock of 4.80 GHz.

Cache configurations also show divergent strategies. The AMD EPYC 9375F has 1 MB of L2 cache per core, while the Intel Xeon w9-3575X has 2 MB per core. However, the AMD chip has a massive 256 MB of shared L3 cache, whereas the Intel chip has 97.5 MB. Both have 80 KB of L1 cache per core. This large L3 cache on the AMD chip is likely a key factor in its performance in data-heavy tasks like compression and encryption.

Memory support is another area of difference. The AMD EPYC 9375F features a twelve-channel memory bus with a memory bandwidth of 576.0 GB/s. The Intel Xeon w9-3575X has an eight-channel memory bus with a bandwidth of 307.2 GB/s. Both support DDR5 memory and ECC. The AMD's higher memory bandwidth is a clear advantage for memory-intensive workloads.

PCIe connectivity also differs. The AMD chip offers Gen 5 with 128 lanes (CPU only), while the Intel chip offers Gen 5 with 112 lanes (CPU only). The power envelopes are similar, with the AMD chip rated at 320 W TDP and the Intel chip at 340 W TDP. The Intel chip has an unlocked multiplier, while the AMD chip does not. The release dates show the AMD chip was released on 2024-10-09, while the Intel chip was released earlier on 2024-08-23.

The Verdict

The benchmark data is unambiguous: the AMD EPYC 9375F is the superior processor for the majority of workloads. Its 15 out of 16 head-to-head benchmark wins, including a decisive 14.9% lead across all Cinebench tests and a 30.1% lead in integer math, demonstrate that its Zen 5 architecture and higher clock speeds deliver more performance per core than the Intel Xeon w9-3575X. The AMD chip's massive 256 MB L3 cache and 576.0 GB/s memory bandwidth also give it a clear edge in data-intensive tasks.

The Intel Xeon w9-3575X is not without merit. Its 44 cores and 88 threads are more than the AMD's 32 and 64, and it wins the floating point math test by 4.8%. This suggests that for workloads that are specifically heavy on floating-point calculations, the Intel chip may be a better choice. Its unlocked multiplier also offers overclocking potential, which could be a consideration for some users.

However, for general-purpose server and workstation tasks, the data indicates that the AMD EPYC 9375F is the better performer. The consistent 14.9% lead in Cinebench and the massive 103.3% lead in the find prime numbers test show that the AMD architecture is more efficient across a broad range of tasks. Users who prioritize raw multi-core performance and data processing should choose the AMD EPYC 9375F, while those with specific floating-point-heavy workloads might consider the Intel Xeon w9-3575X.

Where Each One Wins

The AMD EPYC 9375F is the clear winner in most categories. It dominates in integer math with a 30.1% lead, in physics with a 31.9% lead, and in prime number finding with a 103.3% lead. It also wins in data compression, data encryption, extended instructions, random string sorting, and multithread tests. All Cinebench tests, both single-core and multi-core, are won by the AMD chip with a 14.9% margin. This makes it the best choice for general compute, data processing, and multi-threaded applications.

The Intel Xeon w9-3575X has one specific area of strength: floating point math. Its 4.8% advantage in this test makes it a potential choice for workloads that are heavily dependent on floating-point calculations, such as certain scientific simulations or financial modeling. Its higher core count of 44 versus 32 also provides more raw threads, which could be beneficial in specific highly parallel scenarios where the AMD's per-core advantage does not translate to a win. However, the data shows that in the tested benchmarks, the AMD chip's efficiency overcomes the Intel chip's core count advantage in almost every case.
