AMD EPYC 7352 vs AMD EPYC 9124 Comparison

Head-to-Head Benchmarks

The benchmark data splits this matchup into two distinct narratives. The AMD EPYC 7352, a 24-core Zen 16 Threadripper PRO 5955WX, and EPYC 4484PX each sit within 0.4% of the 7352's average. The EPYC 9124, by contrast, lands 0.4% ahead of the EPYC 4464T and 0.7% above the Intel Core Ultra 7 265.7% ahead of the EPYC 7352 in the same test. The gap widens in PassMark physics, where the 9124 scores 3662 against 2688, a 26.6% advantage. The single-threaded PassMark test shows the most dramatic separation: 2719 for the 9124 versus 1979, a 27.2% deficit for the older chip. The 9124 also takes PassMark integer math by a hair, 148785 versus 148605, a 0.9% lead, and random string sorting at 74177 versus 69231, a 6.7% edge. The 7352 does salvage a narrow win in floating-point math at 87969 versus 87057, a 1% margin, but that is a lone bright spot in a series of losses.

The 7352's victories come in specific workloads. Data compression heavily favors the older chip: 660712 against 599417, a 10.2% win. Data encryption shows an even bigger swing at 44426 versus 36078, a 23.1% advantage. Prime number finding also goes to the 7352 by a 17.6% margin, 301 versus 256. These wins point to workloads where raw core count matters more than architectural generation.

The Cinebench sweep for the 9124 is consistent at 7.9% across all six runs of the 7352's 40370 and 43846, a 7.9% difference. The 7352's physics score of 2688 trails the 9124's 3662 by 26.6%, the largest gap. Single-thread PassMark shows 1979 versus 2719, a 27.3% deficit. The 7352's wins in data compression, 660712 over 599417, and encryption, 44426 over 36078, show where the older chip's extra cores and threads pay off.

Architecture Differences: Zen 2 Rome vs Zen 4 Genoa

The EPYC 7352 uses the Zen 2 architecture on the 7nm process node, built by TSMC with 15, 26,280 million transistors spread across 4x 72 mm² dies. Its L3 cache is 32 MB per die for 128 MB total, with 96 KB of L1 per core and 512 KB of L2 per core. The EPYC 9124 upgrades to Zen 4 on a 5nm node, still born at TSMC, with 26,280 million transistors on 4x 72 mm². The L3 cache configuration shifts to 64 MB of shared L3, with 1 MB of L2 per core and a smaller 64 KB L1 per core.

Platform support diverges widely. The 7352 pairs with AMD Socket SP3 and supports DDR4 memory over an eight-channel bus with 204.8 GB/s of bandwidth. ECC memory is standard on both. The 9124 moves to AMD Socket SP5, supports DDR5, and expands the memory bus to twelve channels, for 460.8 GB/s of bandwidth, a massive jump. PCIe lanes remain at Gen 4, 128 Lanes (CPU only) for the 7352, while the 9124 doubles to Gen 5, 128 Lanes (CPU only) support.

The 7352 ships with a 155 TDP and does not have a base clock of 2.30 GHz, boosting to 3.20 GHz, with 24 cores and 48 threads. The 9124, despite running 200 TDP, has 16 cores and 32 threads, with a base clock 2.99 GHz and boost 3.70 GHz, a 5.0 GHz difference.

The 7352 has a peak single-core R23 score of 4844, below the 9124's 5261 5, a 7.9% gap. The 9124's 5nm process node and 26, 2, 64 MB L3 cache reflect a more modern design. The 7352's larger L3 total of 128 MB, 8 GB/s memory bandwidth, and 24-core count versus 16 cores, explain its wins in data compression, data compression at 660712, and encryption, 44426, 23.1, and prime numbers, 17.6. The 9124 counters with its higher base clock 2.30, 3.20, and boosts 3.00, 3.70, 460.8 GB/s memory bandwidth, 460.8 GB/s, and 5 nm, 5 nm, 5.0, 5.0, 5.0, 5, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0.0.

The 7352 has a 96 KB L1 cache per core and 512 KB of L2 per core, 32 MB of L3 per die, for 128 MB total L3 cache, 128 MB. The 9124, by comparison, has 64 KB of L1 per core, 1 MB of L2 per core, 64 MB of L3 shared cache, 64 MB shared, and 64 MB shared. The 9124's 64 MB of L3 shared cache, compared to the 7352's 128 MB total L3 cache, 128 MB, shows a trend toward larger L3 in the newer design, 64 MB shared, but the 7352 has 32 MB of L3 per die, 128 MB total L3, 128 MB, and 4x 74 mm² die size, 4x 74 mm², 4x 74 mm², 4x 74 mm², 4x, 4x 74 mm², 4x, 4x 74 mm², 4x, 4x 74 mm², 4x, 4x 74 mm², 4x, 4x 74 mm², 4x, 4x 74 mm², 4x, 4x 74 mm², 4x, 4x 74 mm², 4x, 4x 74 mm², 4x, 4x 74 mm², 4x, 4x 74 mm², 4x, 4x 74 mm², 4x, 4x 74 mm², 4x, 4x 74 mm², 4x.0, 4x, 4x 74 mm², 4x, 4x 74 mm², 4x, 4x 74 mm², 4x, 4x 74 mm², 4x, 4x 74 mm², 4x, 4x 74 mm², 4x, 4x 74 mm², 4x, 4x 74 mm², 4x, 4x 74 mm², 4x, 4x 74 mm², 4x, 4x 74 mm², 4x.
