AMD EPYC 9354 vs Intel Xeon 6732P Comparison

The Intel Xeon 6732P and the AMD EPYC 9354 are both 32-core, 64-thread server processors aimed at the same market segment. The recorded head-to-head data shows a clear split: the Intel part wins 11 of 17 tests, the AMD part wins 6. The Intel part carries a higher average benchmark score of 143444 versus 126810, and sits at the 98th percentile of all CPUs, one point above the AMD part's 97th percentile. But the AMD part wins in several specialized workloads, so the choice depends on the workload profile.

Head-to-Head Benchmarks

The most consistent result is the Cinebench family. In Cinebench R15 multi-core, Intel scores 6412 versus AMD's 6221, a 3.1% lead. R15 single-core: 905 versus 878, also 3.1%. R20 multi-core: 26720 versus 25923, 3.1%. R20 single-core: 3772 versus 3659, 3.1%. R23 multi-core: 63621 versus 61722, 3.1%. R23 single-core: 8981 versus 8713, 3.1%. Every Cinebench test, single or multi, shows the same margin. The consistency of that 3.1% across all six versions points to a clock-driven advantage, since the Intel part's boost clock is 4.10 GHz versus 3.80 GHz for the AMD part.

The largest Intel wins are in Passmark floating point math (261703 vs 188894, a 38.5% lead), extended instructions (106697 vs 86176, a 23.8% lead), data compression (1339480 vs 1168626, a 14.6% lead), and integer math (334340 vs 304828, a 9.7% lead). Passmark multithread also goes to Intel, 74849 versus 72615, a 3.1% margin. These are substantial margins, especially the floating point and extended instruction results, which suggest a strong advantage for math-heavy and SIMD-style workloads.

The AMD wins are in a different cluster. Find prime numbers: 934 versus 628, which means AMD leads by 32.8%. Physics: 9281 versus 8109, a 12.6% lead for AMD. Data encryption: 71400 versus 63848, a 10.6% lead. Random string sorting: 140690 versus 133467, a 5.1% lead. Passmark single-thread: 2601 versus 2506, a 3.7% lead. The single-thread Passmark result is notable because it contradicts the Cinebench single-core results, where Intel leads by 3.1% in every version. This indicates the two processors respond differently to the specific instruction mixes in each benchmark.

Context from the nearest rivals: the Intel part's average benchmark score of 143444 places it within 0.2% of the AMD Ryzen 9 PRO 9965X3D (143735), 0.2% ahead of the Intel Xeon 674X (143103), 0.6% behind the Intel Xeon w9-3575X (144323), and 1% behind the AMD EPYC 7643P (144824). The AMD EPYC 9354's average of 126810 puts it 1.6% ahead of the Intel Xeon 6730P (124756), 2.1% ahead of the AMD Ryzen Threadripper PRO 5975WX (124171), 2.3% ahead of the AMD EPYC 7642 (124006), and 2.4% behind the Intel Xeon 6710E (129930). So the Intel part competes in a higher performance tier, while the AMD part sits among slightly lower-scoring rivals.

Architecture Differences

Both are 5 nm parts, but the Intel Xeon 6732P is fabricated by Intel, while the AMD EPYC 9354 is fabricated by TSMC. The Intel architecture is Granite Rapids (Granite Rapids-SP generation), and the AMD architecture is Zen 4 under the Genoa codename. Both have 32 cores and 64 threads. The Intel base clock is 3.80 GHz and boost is 4.10 GHz. The AMD base clock is 3.25 GHz and boost is 3.80 GHz. The higher clocks on the Intel part align with its Cinebench lead.

Cache is a major differentiator. Intel provides 112 KB of L1 per core, 2 MB of L2 per core, and 144 MB of shared L3. AMD provides 64 KB of L1 per core, 1 MB of L2 per core, and 256 MB of shared L3. The AMD part has nearly double the L3 capacity, which may explain its wins in cache-sensitive tests like prime finding and random string sorting. The AMD part also lists 52,560 million transistors across 8x 72 mm² dies; the Intel part has no transistor or die size data recorded.

Memory support is DDR5 for both, but the channel counts differ. Intel uses eight-channel memory with 409.6 GB/s bandwidth. AMD uses twelve-channel memory with 460.8 GB/s bandwidth. Both support ECC. PCIe is Gen 5 for both, with Intel offering 136 lanes (CPU only) and AMD offering 128 lanes. The TDP ratings are 350 for Intel and 280 for AMD. Sockets are incompatible: Intel Socket 4710 versus AMD Socket SP5. The release dates are far apart: Intel on 2025-05-21, AMD on 2022-11-09. The launch MSRP is $5295 for Intel and $3420 for AMD.

The Verdict

The data points to a performance leader in most general-purpose tests: the Intel Xeon 6732P. It wins 11 of 17 head-to-head tests, has a higher average benchmark score (143444 vs 126810), and holds a higher percentile rank (98 vs 97). Its clock advantage (4.10 GHz boost vs 3.80 GHz) and its wins in floating point, integer, compression, and extended instructions make it the stronger choice for compute-heavy server workloads.

The AMD EPYC 9354 is the better pick for workloads that match its specific strengths. It wins in encryption, prime finding, physics, random string sorting, and Passmark single-thread. It also has a larger L3 cache (256 MB vs 144 MB), higher memory bandwidth (460.8 GB/s vs 409.6 GB/s), a twelve-channel memory bus, and a lower TDP (280 vs 350). For security, cryptography, physics simulation, and sorting-heavy tasks, the AMD part has a measurable edge.

There is no universal winner. The Intel part is ahead in the majority of tests, but the AMD part wins in a meaningful subset. The data supports a workload-based decision rather than a single overall champion.
