AMD EPYC 4484PX vs Intel Core 9 273PQE Comparison

Head-to-Head Benchmarks

The head-to-head comparison between the AMD EPYC 4484PX and the Intel Core 9 273PQE shows a decisive overall victory for the AMD part, which wins 13 of the 17 recorded tests. The Intel processor takes the remaining 4 tests, but several of its wins are narrow, while the AMD wins are often substantial.

Starting with the Cinebench suite, the AMD EPYC 4484PX leads across all six benchmarks. In Cinebench R15 multicore, the AMD scores 4330 against Intel's 3950, a 9.6% advantage. The single-core R15 test shows a nearly identical gap: 611 versus 557, also 9.7% ahead. This pattern repeats in Cinebench R20, where the AMD posts 18044 multicore and 2547 single-core, compared to Intel's 16459 and 2323, both deltas again at 9.6%. The R23 results mirror this exactly: 42964 versus 39190 multicore and 6065 versus 5532 single-core, with the same 9.6% margin. The consistency of this 9.6% delta across all Cinebench versions indicates a stable architectural advantage rather than a workload-specific quirk.

The Passmark suite reveals a more nuanced picture. The AMD EPYC 4484PX wins the data compression test with 603371 against 585752, a modest 3% lead. Data encryption shows a much larger gap: 36499 versus 29636, a 23.2% advantage for AMD. Extended instructions follow with 43315 against 38743, an 11.8% lead. The most striking result in the entire comparison is the find prime numbers test, where the AMD part scores 425 against Intel's 198, a massive 114.6% difference. This is the single largest delta in the dataset and suggests a profound difference in how the two processors handle this specific integer workload.

The AMD processor also wins the Passmark multithread test with 50547 versus 46107, a 9.6% margin that again matches the Cinebench delta. The physics test shows a 79.3% advantage for AMD, scoring 4938 against 2754. Random string sorting goes to AMD with 71642 versus 53167, a 34.7% lead.

The Intel Core 9 273PQE claims its wins in floating-point math, integer math, and single-thread tests. The floating-point math result is decisive: Intel scores 125546 against AMD's 96446, a 23.2% advantage in Intel's favor. This is the exact inverse of the data encryption delta, suggesting complementary strengths. Integer math is nearly a tie, with Intel at 164629 and AMD at 162993, just 1% apart. The single-thread Passmark tests (both listed as passmark_single_thread and passmark_singlethread, which record identical scores) show Intel ahead with 4573 versus 4119, a 9.9% lead.

Where Each One Wins

The data indicates clear use-case segregation. The AMD EPYC 4484PX dominates in server and workstation-oriented workloads. Its 23.2% lead in data encryption points to strong cryptographic performance, likely valuable for secure data handling. The 34.7% advantage in random string sorting suggests superior performance in data manipulation tasks. The 79.3% physics advantage indicates strong performance in simulation and physics calculations. The massive 114.6% lead in prime number finding shows exceptional integer computation in specific algorithmic contexts, which could benefit scientific computing or cryptography-related workloads.

The Cinebench results, consistently 9.6% ahead across all versions, indicate that the AMD part has a reliable edge in both multi-threaded rendering and single-threaded rendering tasks. Since the delta is identical across R15, R20, and R23, the advantage scales uniformly regardless of the rendering complexity.

The Intel Core 9 273PQE, despite its overall deficit, has specific strengths. The 23.2% lead in floating-point math is substantial and suggests superior performance in FLOP-heavy applications such as numerical simulation, certain scientific computations, or media processing. The integer math score is essentially flat, with Intel ahead by only 1%, meaning that for general integer workloads, the two processors are effectively equivalent. The 9.9% single-thread Passmark win indicates that Intel has a slight edge in lightly-threaded, latency-sensitive applications, despite losing the single-core Cinebench tests. This discrepancy between Passmark single-thread and Cinebench single-core results is notable and suggests different measurement methodologies capture different aspects of single-thread performance.

For users prioritizing breadth of workload coverage, the AMD EPYC 4484PX is the stronger choice. For workloads dominated by floating-point math or lightly-threaded Passmark-style tasks, the Intel part has a measurable advantage.

Architecture Differences

The two processors diverge significantly in their underlying architectures. The AMD EPYC 4484PX is built on the Zen 4 architecture with the Raphael codename, part of the EPYC 4004 series. It uses a 5 nm process node fabricated by TSMC, with 17,840 million transistors spread across a die size of 2x 71 mm². The Intel Core 9 273PQE uses the Bartlett Lake codename, part of the Core 9 generation, built on a 10 nm process node by Intel. The process node difference, 5 nm versus 10 nm, is a substantial generational gap in fabrication technology.

Cache configurations differ markedly. The AMD part features 64 KB L1 per core, 1 MB L2 per core, and a shared 128 MB L3 cache. Critically, it also includes a 1x 64MB slice of 3D V-Cache, which explains the large L3 total. The Intel processor has 80 KB L1 per core, 2 MB L2 per core, and a shared 36 MB L3. The AMD L3 cache is more than three times larger at 128 MB versus 36 MB, plus the additional V-Cache slice. This cache hierarchy difference likely contributes to the AMD part's strong performance in cache-sensitive workloads like the prime number test and random string sorting.

Clock speeds show a trade-off. The AMD EPYC 4484PX has a base clock of 4.40 GHz and a boost clock of 5.60 GHz. The Intel Core 9 273PQE has a lower base clock of 3.40 GHz but a higher boost clock of 5.90 GHz. The higher AMD base clock suggests better sustained all-core performance at lower frequencies, while Intel's higher boost clock may provide occasional single-core bursts.

Memory support differs as well. The AMD processor supports DDR5 only, with dual-channel memory and a bandwidth of 83.2 GB/s. The Intel part supports both DDR4 and DDR5, also dual-channel, with a slightly higher bandwidth of 89.6 GB/s. Both support ECC memory. The PCIe connectivity differs: AMD provides Gen 5 with 28 lanes from the CPU, while Intel provides Gen 5 with 16 lanes. This gives the AMD part significantly more PCIe bandwidth for expansion.

The AMD EPYC 4484PX integrates Radeon Graphics, while the Intel Core 9 273PQE integrates UHD Graphics 770. The AMD part is classified for the server/workstation market segment, while the Intel part targets the desktop segment. The AMD uses AMD Socket AM5, while Intel uses Intel Socket 1700. Neither processor has an unlocked multiplier.
