AMD EPYC 9184X vs Intel Xeon w5-3525 Comparison

The AMD EPYC 9184X and Intel Xeon w5-3525 are both 16-core, 32-thread server/workstation processors, but benchmark data reveals they are optimized for very different workloads. The EPYC 9184X wins 13 of 17 head-to-head tests, while the Xeon w5-3525 takes 4, with the margins varying dramatically by task type. Average benchmark scores are nearly identical — 68202 for the AMD part versus 67673 for the Intel part, a 0.8% gap that places both at the 94th percentile of all CPUs. The real story is not overall performance, but where each chip applies its resources.

Head-to-Head Benchmarks

The AMD EPYC 9184X dominates the Cinebench suite across the board. In Cinebench R23 multicore, it scores 40515 against 38964, a 4% advantage. The same 4% margin appears in Cinebench R15 multicore (4083 vs 3927) and R20 multicore (17016 vs 16364). Single-core Cinebench results follow the same pattern: R23 single-core shows 5719 vs 5500, a 4% lead, and R20 single-core shows 2401 vs 2310, a 3.9% edge. These consistent margins suggest the AMD chip's architectural efficiency translates directly into rendering and CPU-encoding workloads.

The gap widens dramatically in several PassMark tests. The EPYC 9184X scores 6674 in PassMark physics versus 3002 for the Xeon, a staggering 122.3% advantage. Prime number finding shows a 113.3% lead (465 vs 218). Data encryption favors AMD by 22.5% (37376 vs 30507), and random string sorting by 25.7% (79913 vs 63579). These are not marginal wins — they represent fundamentally different performance profiles for computational workloads.

The Intel Xeon w5-3525 fights back in specific areas. PassMark floating point math is a decisive Intel victory: 121050 vs 95476, a 21.1% lead. Extended instructions go Intel's way by 11.5% (49242 vs 43562). PassMark single-thread performance also favors Intel: 3330 vs 2822, a 15.3% margin. Integer math is nearly a tie, with AMD ahead by just 1.4% (157483 vs 155282). Data compression is also close, with AMD leading 614873 vs 607435, a 1.2% gap. PassMark multithread goes to AMD by 4% (47665 vs 45841).

Architecture Differences

The two processors are built on fundamentally different silicon. The AMD EPYC 9184X uses TSMC's 5 nm process with a Zen 4 architecture under the Genoa-X codename. It packs 90,160 million transistors across 8 die, each measuring 72 mm². The Intel Xeon w5-3525 uses Intel's 10 nm process with a Sapphire Rapids codename, spanning 4 die of 477 mm² each. The process node difference is significant — 5 nm versus 10 nm — and helps explain the AMD chip's power efficiency in dense compute tasks.

Cache configurations diverge sharply. The EPYC 9184X features 64 KB of L1 cache per core, 1 MB of L2 per core, and a massive 768 MB of shared L3 cache. The Xeon w5-3525 offers 80 KB L1 per core, 2 MB L2 per core, but only 45 MB of L3 total. The 768 MB L3 cache on the AMD part is a defining feature — it enables the massive wins in physics and prime number tests, where large working sets fit entirely in cache.

Memory subsystems also differ. Both support DDR5 and ECC memory, but the AMD part uses a twelve-channel memory bus delivering 460.8 GB/s bandwidth. The Intel chip uses an eight-channel bus with 307.2 GB/s. This 50% bandwidth advantage for AMD explains its strong showing in data encryption and random string sorting, which are often memory-bound. PCIe connectivity is similarly lopsided: AMD offers 128 Gen 5 lanes (CPU only), while Intel provides 112 Gen 5 lanes.

Where Each One Wins

The AMD EPYC 9184X is the clear choice for physics simulation, prime number computation, and data encryption. Its 122.3% physics win and 113.3% prime number win are the largest margins in the entire comparison. These workloads benefit enormously from the 768 MB L3 cache, which reduces memory latency and keeps massive datasets on-die. The 22.5% encryption advantage and 25.7% random string sorting win further cement its position for security-related and data-processing tasks.

For multithreaded rendering, the AMD part maintains a steady 4% lead across all three Cinebench versions. This consistency suggests the EPYC 9184X extracts more throughput per core in sustained all-core workloads, likely due to its higher base clock of 3.55 GHz versus 3.20 GHz for the Intel chip. The AMD processor also wins PassMark multithread by 4%, reinforcing its all-core superiority.

The Intel Xeon w5-3525 wins where floating point math dominates. Its 21.1% lead in floating point math (121050 vs 95476) makes it the better fit for scientific computing, financial modeling, and any workload heavy on trigonometric or transcendental functions. The 11.5% extended instructions win indicates stronger SIMD performance for vectorized code. Single-threaded tasks that rely on raw clock speed favor Intel — its boost clock reaches 4.80 GHz versus 4.20 GHz for AMD, which explains the 15.3% single-thread PassMark advantage.

Workloads that combine both strengths, such as integer math and data compression, end up nearly tied. The EPYC 9184X edges integer math by 1.4% and data compression by 1.2%, but these are effectively statistical dead heats given the 0.8% overall average score difference.
