AMD EPYC 9375F vs Intel Xeon w9-3595X Comparison

Head-to-Head Benchmarks

The benchmark comparison between the Intel Xeon w9-3595X and AMD EPYC 9375F shows a clear pattern: the Intel part wins 12 of 16 recorded tests, while the AMD part takes 4. The margins, however, tell a more nuanced story than the raw win count suggests.

Starting with the Cinebench suite, the Intel Xeon w9-3595X holds a consistent but modest lead. In Cinebench R15 multicore, Intel scores 8497 against AMD's 8205, a 3.6% advantage. The single-core R15 test shows Intel at 1199 versus 1158, again 3.5% ahead. Moving to R20, Intel posts 35407 multicore and 4998 single-core, while AMD records 34188 and 4826 respectively, with the same 3.6% delta in both. The R23 multicore result follows suit: Intel at 84304, AMD at 81402, a 3.6% gap. These are narrow margins, indicating that in pure CPU rendering workloads, the two processors are closely matched.

The Passmark suite reveals where the Intel part pulls away decisively. Data compression shows Intel at 1831962 against AMD's 1496149, a 22.4% lead. Data encryption is even more lopsided: Intel scores 92249, AMD 73634, a 25.3% advantage. Floating point math sees Intel at 379008 versus AMD's 260392, a massive 45.6% gap, the largest margin in the entire comparison. Integer math follows with Intel at 473507 and AMD at 387901, a 22.1% lead. Random string sorting goes to Intel by 18.4% (190745 vs 161091), and extended instructions favor Intel by 11.3% (142785 vs 128296). The Passmark multithread test is closer, with Intel at 99576 and AMD at 95768, a 4% lead.

The AMD EPYC 9375F claims its wins in specific workloads. The most dramatic is the find prime numbers test, where AMD scores 1397 against Intel's 580. That translates to a 58.5% advantage for AMD, a staggering reversal. Physics simulation also goes to AMD, with a score of 9019 versus Intel's 5842, a 35.2% lead. In single-thread Passmark tests, AMD edges ahead with 3762 versus Intel's 3720, a slim 1.1% margin, recorded identically in both single_thread and singlethread entries.

Where Each One Wins

The data points to distinct use-case strengths. The Intel Xeon w9-3595X dominates throughput-heavy, data-intensive workloads. Encryption, compression, integer math, floating point math, and string sorting all lean heavily toward Intel, with leads ranging from 11.3% to 45.6%. This suggests a strong fit for database operations, scientific computing, financial modeling, and any workload that stresses raw arithmetic throughput or memory-intensive data manipulation.

The AMD EPYC 9375F, by contrast, wins where specialized instruction efficiency or physics simulation matters. The prime number finding test is an extreme outlier, with AMD at more than double Intel's score, indicating a significant advantage in certain algorithmic patterns. The physics test, with AMD 35.2% ahead, points to strength in simulation workloads that depend on particular math patterns rather than raw core count. The single-thread Passmark win, though narrow, shows AMD has a slight edge in lightly threaded tasks.

In the Cinebench suite, the two are nearly inseparable, with Intel holding a small but consistent 3.5% to 3.6% margin across all five tests. That means for general 3D rendering or video encoding, the choice between the two is less critical than in specialized workloads. The overall average benchmark score reinforces this split: Intel's average is 209881, while AMD's is 162497, a substantial gap that reflects Intel's broader dominance across the test suite.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Xeon w9-3595X uses the Sapphire Rapids architecture, built on a 10 nm process at Intel's own foundry. It packs 60 cores and 120 threads, with a base clock of 2.00 GHz and a boost clock of 4.80 GHz. The die is composed of 4x 477 mm² chiplets, and the cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and a large 112.5 MB L3 cache.

The AMD EPYC 9375F belongs to the EPYC 9005 series, based on Zen 5 architecture, codenamed Turin. It is manufactured on a 4 nm process by TSMC, with 66,520 million transistors spread across 8x 70.6 mm² chiplets. It offers 32 cores and 64 threads, with a base clock of 3.85 GHz and the same 4.80 GHz boost clock as Intel. The L1 cache is identical at 80 KB per core, but L2 drops to 1 MB per core, while L3 jumps to 256 MB shared.

These architectural choices explain the benchmark outcomes. Intel's higher core count (60 vs 32) drives its multicore wins, while AMD's higher base clock (3.85 GHz vs 2.00 GHz) contributes to its single-thread performance. The L3 cache disparity is notable: 256 MB on AMD versus 112.5 MB on Intel, yet Intel still wins most cache-sensitive tests, suggesting that memory controller efficiency or core count matters more than raw L3 size in these benchmarks.

Memory support also diverges. Both support DDR5 and ECC memory, but Intel uses an eight-channel memory bus with 307.2 GB/s bandwidth, while AMD uses a twelve-channel bus with 576.0 GB/s bandwidth. Despite AMD's higher theoretical memory bandwidth, Intel wins the data-heavy Passmark tests, indicating that other factors, such as core count or instruction scheduling, play a larger role in those specific workloads.

Specification Differences

The recorded specifications separate the two on several key fields. Core count: Intel has 60 cores and 120 threads, AMD has 32 cores and 64 threads. Base clock: Intel runs at 2.00 GHz, AMD at 3.85 GHz. Boost clock is identical at 4.80 GHz for both. Thermal design power: Intel is rated at 385 W, AMD at 320 W. Socket: Intel uses Socket 4677, AMD uses Socket SP5.

The cache tiers differ beyond just L3. L2 cache is 2 MB per core on Intel versus 1 MB per core on AMD. L3 cache is 112.5 MB on Intel versus 256 MB shared on AMD. Memory bandwidth shows AMD ahead at 576.0 GB/s versus Intel's 307.2 GB/s, with AMD also offering more memory channels (twelve versus eight). PCIe lanes favor AMD: 128 Gen 5 lanes (CPU only) versus Intel's 112 Gen 5 lanes.

Process node and foundry differ: Intel uses 10 nm at its own foundry, AMD uses 4 nm at TSMC. Transistor count is only listed for AMD at 66,520 million. Die size is 4x 477 mm² for Intel and 8x 70.6 mm² for AMD. The multiplier is unlocked on Intel but locked on AMD. Release dates are close: Intel launched on 2024-08-23, AMD on 2024-10-09. Both are active production parts. The launch MSRP for Intel is $5889, for AMD it is $5306.

The Verdict

The benchmark data shows a clear overall winner in the Intel Xeon w9-3595X, which takes 12 of 16 tests and holds a higher average benchmark score of 209881 versus AMD's 162497. The Intel part is the better choice for workloads that stress data manipulation, encryption, compression, and floating point or integer math, where its leads range from 11.3% to 45.6%. It also edges ahead in all Cinebench rendering tests by a small but consistent margin.

The AMD EPYC 9375F is the pick for specific niches. Its 58.5% lead in prime number finding suggests an advantage in algorithmic or cryptographic workloads that rely on similar patterns. The 35.2% win in physics simulation points to strength in certain simulation environments. Its narrow single-thread Passmark win, while small, indicates slightly better performance in lightly threaded tasks.

For most server or workstation buyers, the Intel Xeon w9-3595X offers broader performance across the recorded benchmarks, despite a higher launch MSRP of $5889 versus AMD's $5306. The AMD part, with its lower TDP of 320 W versus Intel's 385 W and higher memory bandwidth, may appeal to those prioritizing energy efficiency or memory throughput, though the benchmark data does not show those advantages translating into wins in the tested workloads. The choice ultimately depends on whether the workload matches AMD's specific strengths or aligns with Intel's broader dominance.
