AMD EPYC 4484PX vs AMD EPYC 9124 Comparison

The Verdict

The benchmark data presents a clear split between these two AMD EPYC processors. The AMD EPYC 4484PX wins 15 of the 17 recorded head-to-head tests, while the AMD EPYC 9124 takes only 2. For workloads that rely on raw per-core speed, high clock rates, and large L3 cache, the EPYC 4484PX is the stronger choice. For workloads that stress memory bandwidth or benefit from additional cores, the EPYC 9124 offers specific advantages.

The EPYC 4484PX posts a 15.3% advantage across every Cinebench test, both single-core and multi-core, and its PassMark single-thread score is 51.5% higher. This makes it the obvious pick for latency-sensitive tasks, database queries, and any application where a single thread's speed dominates performance.

The EPYC 9124, despite having 16 cores versus 12, loses in every multi-core Cinebench test by the same 15.3% margin. Its wins come in extended instructions (0.1% ahead) and random string sorting (3.4% ahead), which points to specific memory or instruction-level advantages rather than general processing strength. The data suggests the EPYC 9124 suits workloads with very high memory bandwidth demands, given its twelve-channel memory bus and 460.8 GB/s bandwidth versus the 4484PX's dual-channel 83.2 GB/s.

The Verdict: choose the EPYC 4484PX for maximum per-core performance and overall benchmark dominance. Choose the EPYC 9124 for memory-bandwidth-intensive tasks or when the platform's PCIe lane count (128 versus 28) matters more than raw compute speed.

Architecture Differences

Both processors use the Zen 4 architecture, built on TSMC's 5 nm process, but they belong to different EPYC families with distinct designs. The EPYC 4484PX comes from the EPYC 4004 series, codenamed Raphael, and fits into AMD Socket AM5. The EPYC 9124 is from the EPYC 9004 series, codenamed Genoa, and uses AMD Socket SP5.

The core counts differ: the 4484PX has 12 cores and 24 threads, while the 9124 has 16 cores and 32 threads. Clock speeds also diverge sharply. The 4484PX runs at a 4.40 GHz base clock and boosts to 5.60 GHz. The 9124 runs at 3.00 GHz base and 3.70 GHz boost. This explains the 4484PX's decisive single-thread wins.

Cache configuration is another major split. The 4484PX carries 128 MB of shared L3 cache, augmented by a 1x 64MB 3D V-Cache slice. The 9124 has only 64 MB of shared L3 cache and no 3D V-Cache. Both share the same L1 (64 KB per core) and L2 (1 MB per core) layouts.

The silicon itself differs. The 4484PX uses 17,840 million transistors across 2x 71 mm² dies. The 9124 uses 26,280 million transistors across 4x 72 mm² dies. The 9124's larger transistor count and additional dies support its memory and I/O capabilities.

Memory support sees the largest architectural gap. Both support DDR5 and ECC memory, but the 4484PX uses a dual-channel memory bus with 83.2 GB/s bandwidth, while the 9124 uses a twelve-channel bus with 460.8 GB/s bandwidth. PCIe connectivity also differs: the 4484PX provides Gen 5 with 28 lanes (CPU only), while the 9124 provides Gen 5 with 128 lanes (CPU only). The 4484PX includes integrated Radeon Graphics; the 9124 has no integrated graphics.

Head-to-Head Benchmarks

The Cinebench results are uniform: the EPYC 4484PX wins every test by exactly 15.3%. In Cinebench R15, scores are 4330 versus 3756 for multi-core and 611 versus 530 for single-core. In R20, the 4484PX scores 18044 versus 15652 multi-core and 2547 versus 2209 single-core. In R23, it scores 42964 versus 37269 multi-core and 6065 versus 5261 single-core. The consistency of the delta suggests a fundamental clock-speed advantage rather than workload-specific behavior.

PassMark results show a broader spread. The 4484PX wins multithread with 50547 versus 43846, a 15.3% margin matching the Cinebench pattern. Its single-thread score of 4119 versus 2719 is a 51.5% advantage, the largest in the dataset. Physics testing shows a 34.8% lead (4938 versus 3662). Find prime numbers sees the 4484PX score 425 versus 256, a 66% advantage. Floating point math favors the 4484PX by 10.8% (96446 versus 87057), and integer math by 9.5% (162993 versus 148785).

Data compression and encryption are close. The 4484PX wins compression by 0.7% (603371 versus 599417) and encryption by 1.2% (36499 versus 36078). Extended instructions go to the 9124 by a razor-thin 0.1% (43380 versus 43315). Random string sorting is the 9124's clearest win at 3.4% (74177 versus 71642).

The average benchmark scores place the 4484PX at 67822 versus 65104 for the 9124, a 4.2% difference. The 4484PX ranks in the 94th percentile of all CPUs, while the 9124 sits in the 93rd.

Where Each One Wins

The EPYC 4484PX wins in every category that stresses raw compute speed. Its 51.5% single-thread lead makes it ideal for lightly threaded applications, database transactions, and real-time processing. The 15.3% multi-core advantage across all Cinebench versions and PassMark multithread confirms that even with fewer cores, higher clocks and the 3D V-Cache deliver superior throughput. The 66% lead in prime number finding and 34.8% lead in physics suggest strong integer and simulation performance. The 128 MB L3 cache plus 64MB V-Cache slice likely explains its wins in data compression (0.7%) and encryption (1.2%), where cache residency matters.

The EPYC 9124 wins in two specific areas. Extended instructions show a marginal 0.1% lead, indicating slightly better SIMD or specialized instruction throughput. Random string sorting shows a 3.4% win, which may reflect its twelve-channel memory bus providing higher sustained bandwidth for memory-heavy operations. The 9124's 460.8 GB/s bandwidth is 5.5 times the 4484PX's 83.2 GB/s, so any workload that streams large datasets will favor the 9124 despite its lower compute scores.

For capacity-oriented workloads, the 9124's 16 cores and 128 PCIe lanes make it the platform choice for dense virtualization or storage servers. The 4484PX, with 28 PCIe lanes and integrated graphics, suits compact single-socket systems where per-core performance is paramount.
