AMD EPYC 7C13 vs Intel Xeon w9-3595X Comparison

The Verdict

The benchmark data splits this comparison into two very clear profiles. The Intel Xeon w9-3595X wins 14 of the 16 recorded head-to-head tests, while the AMD EPYC 7C13 takes only 2. The Intel part leads by substantial margins in most multi-threaded and single-threaded workloads, with deltas ranging from 7.6% to 67.9%. The AMD EPYC 7C13 counters with a 19.6% win in data encryption and a 3.9% win in integer math, but those are isolated victories.

The Intel Xeon w9-3595X is the pick for users prioritizing raw compute throughput, especially in rendering, floating-point math, extended instruction sets, and random string sorting. Its 99th percentile ranking among all CPUs, combined with an average benchmark score of 209,881, places it ahead of its nearest rivals. The AMD EPYC 7C13, at the 98th percentile with an average score of 167,788, is the choice for workloads that lean on encryption performance or integer-heavy tasks, and for systems where the lower 225 TDP and DDR4 memory support are decisive factors.

Architecture Differences

The two processors come from different design philosophies. The Intel Xeon w9-3595X is built on the Sapphire Rapids architecture, manufactured on a 10 nm process at Intel's own foundry. It uses a 4x 477 mm² die configuration. The AMD EPYC 7C13 is a Zen 3 design, built on a 7 nm process at TSMC, with a die size of 8x 81 mm² and 33,200 million transistors.

Core counts differ slightly: the Intel part has 60 cores and 120 threads, while the AMD part has 64 cores and 128 threads. The AMD chip holds a 4-core advantage, but the Intel chip compensates with a much higher boost clock of 4.80 GHz versus 3.68 GHz, and a higher base clock of 2.00 GHz versus 2.00 GHz (recorded as 2000.00 MHz for AMD). The Intel processor's base clock is listed as 2.00, and the AMD part's base clock is 2000.00, which are the same value in different units.

Cache hierarchies are fundamentally different. The Intel Xeon w9-3595X has 80 KB of L1 per core, 2 MB of L2 per core, and 112.5 MB of L3 cache. The AMD EPYC 7C13 has 64 KB of L1 per core, 512 KB of L2 per core, and a much larger 256 MB of shared L3 cache. The AMD part's L3 advantage is substantial, but it does not translate into wins in most benchmark categories.

Memory support also diverges. The Intel part uses DDR5 with an eight-channel bus and 307.2 GB/s of bandwidth. The AMD part uses DDR4 with an eight-channel bus and 204.8 GB/s of bandwidth. Both support ECC memory. PCIe connectivity differs: the Intel Xeon w9-3595X offers Gen 5 with 112 lanes from the CPU, while the AMD EPYC 7C13 offers Gen 4 with 128 lanes.

The Intel processor is unlocked (multiplier unlocked) and has a TDP of 385. The AMD part is locked and has a TDP of 225. The Intel part is active in production, released in August 2024, while the AMD part's release date is not recorded in the database.

Head-to-Head Benchmarks

The Cinebench results show a consistent pattern. In Cinebench R15 multi-core, the Intel Xeon w9-3595X scores 8,497 against the AMD EPYC 7C13's 6,539, a 29.9% lead. Single-core in R15 follows the same delta: 1,199 versus 923, again 29.9%. Cinebench R20 multi-core sees Intel at 35,407 versus AMD's 27,246, a 30.0% advantage. R20 single-core is 4,998 versus 3,846, also 30.0%. Cinebench R23 multi-core shows 84,304 versus 64,873, a 30.0% gap. These are near-uniform margins, indicating a consistent per-clock performance advantage for the Intel architecture in rendering workloads.

The PassMark suite reveals where each part excels. The largest Intel win is in extended instructions: 142,785 versus 85,034, a 67.9% delta. Floating-point math also favors Intel heavily: 379,008 versus 266,846, a 42.0% lead. Random string sorting goes to Intel at 190,745 versus 131,361, a 45.2% margin. Single-thread performance is 42.1% ahead for Intel (3,720 versus 2,618). Multi-thread performance is 30.5% ahead (99,576 versus 76,322). Data compression favors Intel at 17.3% (1,831,962 versus 1,562,251). Physics tests show a 19.1% Intel lead (5,842 versus 4,904). Prime number finding is closer, with Intel ahead by 7.6% (580 versus 539).

The AMD EPYC 7C13 wins two tests. Data encryption shows AMD at 114,769 versus Intel's 92,249, a 19.6% advantage. Integer math is nearly even, with AMD at 492,554 versus Intel's 473,507, a 3.9% lead. These wins indicate specific instruction-level efficiencies in the Zen 3 architecture for cryptographic and integer operations, but they do not offset the broader Intel dominance.

Looking at the nearest rivals for context, the Intel Xeon w9-3595X sits 3.7% behind the AMD EPYC 9455P in average score, but 7.7% ahead of the Intel Xeon 6741P, 8.1% ahead of the AMD EPYC 9335, and 8.5% ahead of the Intel Xeon 678X. The AMD EPYC 7C13 is 2.3% behind the AMD Ryzen Threadripper PRO 3995WX, but 3.3% ahead of the AMD EPYC 9375F, 3.6% ahead of the AMD EPYC 7663, and 4.6% ahead of the AMD EPYC 9355P.

Where Each One Wins

The Intel Xeon w9-3595X is the dominant choice for rendering and media creation. Cinebench R15, R20, and R23 multi-core tests all show a 30% lead. The 60-core part with a 4.80 GHz boost clock is clearly suited for threaded workloads that scale well, such as 3D rendering, video encoding, and simulation. Its 67.9% lead in extended instructions (SIMD-heavy workloads) further reinforces this. Floating-point math, a proxy for scientific computing, is 42.0% ahead. Random string sorting, relevant for database and text processing, is 45.2% ahead. Single-thread performance is also 42.1% ahead, meaning the Intel part is not just a multi-core brute; it also excels in lightly threaded tasks.

The AMD EPYC 7C13 wins in data encryption and integer math. The 19.6% encryption advantage suggests the Zen 3 architecture has hardware-accelerated cryptography paths that outperform the Intel design. The 3.9% integer math lead is narrow but consistent, pointing to efficiency in general-purpose arithmetic. For systems that prioritize security-related workloads, virtual private networks, or database operations with heavy integer arithmetic, the AMD part offers a specific edge. Its 128 PCIe Gen 4 lanes also provide more total I/O lanes, though at a lower generation speed, and its 256 MB L3 cache is double the Intel's 112.5 MB, which can help with data locality in certain server workloads.
