AMD EPYC 4585PX vs Intel Xeon w7-2595X Comparison

Head-to-Head Benchmarks

The AMD EPYC 4585PX wins the benchmark count decisively, taking 11 of 17 comparisons, but the Intel Xeon w7-2595X claims the most lopsided single-workload victories. In Cinebench tests, the AMD part sweeps all six: it leads by 9.2% in R15 multi-core (6093 vs 5530), 9.3% in R15 single-core (860 vs 780), 9.2% in R20 multi-core (25389 vs 23042), 9.3% in R20 single-core (3584 vs 3252), 9.2% in R23 multi-core (60451 vs 54863), and 9.2% in R23 single-core (8534 vs 7745). These are consistent, uniform margins across rendering workloads, suggesting a fundamental architectural advantage rather than a benchmark-specific quirk.

The PassMark suite tells a more divided story. The AMD EPYC 4585PX crushes the Intel part in physics simulation, scoring 6612 versus 2759 — a 58.3% advantage that is the largest margin in either direction. It also wins find prime numbers by 52.7% (547 vs 259), single-thread by 18% (4538 vs 3723), and multithread by 6.2% (68908 vs 64628). These results point to superior per-core execution efficiency and clock speed utilization.

The Intel Xeon w7-2595X fights back in data-heavy and instruction-heavy workloads. It wins floating point math by 32.4% (202906 vs 153219), extended instructions by 11.7% (77613 vs 69457), data compression by 11.1% (983046 vs 884774), random string sorting by 7.4% (102230 vs 95210), data encryption by 5.4% (49782 vs 47224), and integer math by 5.2% (261384 vs 248563). The floating point margin is particularly notable — it is the Intel chip's largest win and nearly reverses the overall narrative, showing that raw core count (26 vs 16) still matters when workloads scale across many threads.

Looking at overall averages, the Intel Xeon w7-2595X posts an average benchmark score of 108663, which is 9.4% higher than the AMD EPYC 4585PX's 99324. Both processors sit at the 97th percentile of all CPUs, meaning either choice lands in the top tier of available hardware. The Intel part's nearest rival, the AMD Ryzen 9 PRO 9955, scores 110612 — just 1.8% higher — while the AMD EPYC 4585PX sits 0.8% above the AMD Ryzen Threadripper PRO 5965WX (98504) and 1.9% above the AMD Ryzen 9 9955HX3D (97453).

The Verdict

The data supports a clear split decision. The AMD EPYC 4585PX is the better choice for single-threaded responsiveness, physics simulation, and prime-number workloads — its 58.3% lead in physics and 52.7% lead in prime finding are too large to ignore for those specific tasks. It also wins every Cinebench test, making it the stronger rendering performer across all three Cinebench versions. The AMD chip achieves this with 16 cores and 32 threads, suggesting its Zen 5 architecture extracts significantly more work per core than Intel's Sapphire Rapids design.

The Intel Xeon w7-2595X is the pick for floating point math, data compression, encryption, and extended instruction workloads. Its 32.4% lead in floating point and 11.7% lead in extended instructions indicate a broader execution pipeline or better SIMD handling. The average benchmark score favors Intel by 9.4%, and its 26 cores and 52 threads provide more parallel headroom for multi-threaded data processing.

For buyers prioritizing overall average performance across a mixed workload, the Intel Xeon w7-2595X wins. For buyers prioritizing per-core speed, physics, and Cinebench rendering, the AMD EPYC 4585PX wins. The AMD chip's 18% single-thread lead is substantial and will be felt in everyday interactive use, despite the Intel chip's higher average score.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Xeon w7-2595X uses the Sapphire Rapids architecture on a 10 nm process fabricated by Intel, while the AMD EPYC 4585PX uses the Zen 5 architecture on a 4 nm process from TSMC. The process node difference is significant — AMD's 4 nm node is two generations ahead of Intel's 10 nm, which helps explain the AMD chip's higher clock speeds and better per-core efficiency despite fewer cores.

The Intel chip integrates 26 cores and 52 threads, while the AMD chip has 16 cores and 32 threads. Both use 80 KB of L1 cache per core, but the L2 cache differs: Intel provides 2 MB per core, while AMD provides 1 MB per core. The L3 cache is where AMD takes a decisive lead — 128 MB total versus Intel's 48.75 MB. This 2.6x L3 advantage likely contributes to the AMD chip's strong performance in Cinebench and physics workloads, where large working sets benefit from on-chip caching.

The AMD EPYC 4585PX includes Radeon Graphics integrated, while the Intel Xeon w7-2595X has no integrated graphics. The AMD chip also carries 16,630 million transistors across two 70.6 mm² dies, while the Intel chip's transistor count and die size are not listed in the data. The AMD chip is built on the EPYC 4005 series platform with the Grado codename, while Intel's is part of the Xeon W generation.

Specification Differences

The core and thread counts differ substantially: Intel has 26 cores and 52 threads, AMD has 16 cores and 32 threads. The AMD EPYC 4585PX runs at a 4.30 GHz base clock and 5.70 GHz boost clock, compared to Intel's 2.80 GHz base and 4.80 GHz boost. The AMD chip's boost clock is 0.9 GHz higher, and its base clock is 1.5 GHz higher — a massive base clock advantage that explains its single-thread dominance.

Thermal design power also diverges: Intel is rated at 250 W TDP, AMD at 170 W TDP. The AMD chip delivers higher clock speeds and competitive multi-thread performance while drawing 80 W less. Memory support differs as well — both use DDR5, but Intel runs quad-channel with 153.6 GB/s bandwidth, while AMD runs dual-channel with 89.6 GB/s. The Intel chip has 64 PCIe Gen 5 lanes (CPU only), while AMD has 24 PCIe Gen 5 lanes.

The sockets are incompatible: Intel uses Socket 4677, AMD uses Socket AM5. The Intel chip has an unlocked multiplier; the AMD chip does not. The AMD EPYC 4585PX launched on 2025-05-12 with a launch MSRP of $699, while the Intel Xeon w7-2595X launched on 2024-08-23 with a launch MSRP of $2039. Both support ECC memory and target the server/workstation segment.

Where Each One Wins

The AMD EPYC 4585PX wins in Cinebench rendering workloads across all three versions (R15, R20, R23) for both multi-core and single-core tests. It also dominates physics simulation, prime number finding, and single-thread PassMark tests. The AMD chip is the clear choice for interactive workstation use, simulation-heavy scientific computing, and any workload where per-core speed matters more than raw throughput. Its 18% single-thread lead and 58.3% physics lead make it the better pick for CAD, real-time rendering previews, and physics-based simulation.

The Intel Xeon w7-2595X wins in floating point math, data compression, data encryption, extended instructions, integer math, and random string sorting. It also holds the higher average benchmark score overall. The Intel chip is the better choice for data center-style workloads: encryption, compression, and floating-point-heavy number crunching. Its 64 PCIe lanes and quad-channel memory bandwidth (153.6 GB/s) make it suitable for systems with extensive I/O requirements, and its 32.4% floating point lead suggests superior SIMD throughput for scientific computing and financial modeling.

The decision ultimately hinges on workload profile. Rendering and single-thread tasks favor AMD; data processing and floating point favor Intel. The AMD EPYC 4585PX achieves its wins with 16 cores and 32 threads at 170 W TDP, while the Intel Xeon w7-2595X needs 26 cores and 52 threads at 250 W TDP to secure its victories. Both sit at the 97th percentile of all CPUs, so neither choice is a weak option — but the specific benchmark wins point to different strengths that should guide the final selection.
