AMD EPYC 4484PX vs Intel Core Ultra 7 265 Comparison

Head-to-Head Benchmarks

The head-to-head data shows a decisive overall win for the AMD EPYC 4484PX, which takes 13 of the 17 recorded comparisons. The Intel Core Ultra 7 265 wins 4. The largest single margin belongs to the AMD part in Cinebench R20 multicore, where it scores 18044 against 6268, a 187.9% advantage. That is the standout gap in the entire dataset. The same test in single-core shows a similar scale of difference: 2547 versus 884, a 188.1% lead for AMD. These two results dwarf every other delta in the comparison.

Outside of Cinebench R20, the AMD chip wins most other contests by more modest margins. In Cinebench R15 multicore, it scores 4330 against 4255, a 1.8% edge. Cinebench R23 multicore follows the same pattern: 42964 versus 42216, again a 1.8% lead. Single-core results in R15 and R23 are also 1.8% in AMD's favor, with scores of 611 vs 600 and 6065 vs 5960, respectively. The Cinebench R15 single-core delta of 1.8% is exactly the same as the multicore delta of 1.8%, and the R23 single-core delta of 1.8% matches the R23 multicore delta of 1.8%. Consistency across the Cinebench suite is notable.

PassMark results tell a more mixed story. AMD wins integer math by 20.9%, scoring 162993 to 134773. It wins data compression by 15.4%, with 603371 to 522983. Random string sorting goes to AMD by 12.2%, 71642 to 63833. Extended instructions favor AMD by 4.4%, 43315 to 41478. Find prime numbers is close, AMD ahead by 1.7%, 425 to 418. The multithread score also goes to AMD by 1.7%, 50547 to 49682. Physics is a major AMD win: 4938 to 2923, a 68.9% margin.

The Intel part takes the remaining four. Its biggest win is floating point math, where it scores 172776 against AMD's 96446, a 44.2% lead for Intel. Data encryption goes to Intel by 9.8%, 40456 to 36499. Single-thread PassMark also favors Intel: 4689 versus 4119, a 12.2% lead. That same 12.2% appears in the duplicate single-thread entry, which records the same scores. These Intel wins are concentrated in specific workloads: floating point throughput, encryption, and PassMark's single-thread metric.

The average benchmark score for the AMD part is 67822, placing it in the 94th percentile of all CPUs in the database. The Intel part averages 64640, which lands in the 93rd percentile. The AMD chip's nearest rivals, by average score, are the AMD Ryzen Threadripper PRO 5955WX at 67868 (a 0.1% difference), the Intel Xeon w5-3525 at 67673 (0.2% difference), the AMD EPYC 7352 at 68118 (0.4% difference), and the Intel Core Ultra 9 275HX at 67469 (0.5% difference). For the Intel Core Ultra 7 265, the nearest rivals are the AMD EPYC 4464P at 64823 (0.3% difference), the Intel Core Ultra 7 265F at 64438 (0.3% difference), the AMD EPYC 7343 at 64202 (0.7% difference), and the AMD EPYC 9124 at 65104 (0.7% difference). The two parts sit in the same performance neighborhood overall, but the head-to-head reveals where each has clear strengths.

The Verdict

The data points to the AMD EPYC 4484PX as the stronger all-around part in this pairing. It wins the majority of benchmark comparisons, including every Cinebench test, and its average score of 67822 exceeds the Intel part's 64640. It also holds a one-point percentile advantage, 94 versus 93. For workloads that stress integer math, data compression, physics, and multithreaded rendering, the AMD part is the clear choice. The 187.9% and 188.1% leads in Cinebench R20 are especially decisive.

The Intel Core Ultra 7 265 is not without its own territory. It wins floating point math by 44.2%, data encryption by 9.8%, and single-thread PassMark by 12.2%. Anyone whose primary tasks are floating point heavy, encryption heavy, or dependent on PassMark single-thread performance should consider the Intel part. Its 20 cores versus AMD's 12 threads advantage does not translate into a win in multithread PassMark, where AMD leads by 1.7%.

There is no overall winner that dominates every metric. The AMD EPYC 4484PX dominates the broader benchmark set, while the Intel Core Ultra 7 265 claims specific, well-defined wins. For general server or workstation use, the data favors AMD. For floating point and encryption workloads, the Intel part is the better match.

It also wins physics by 68.9%, integer math by 20.9%, data compression by 15.4%, random string sorting by 12.2%, extended instructions by 4.4%, and find prime numbers by 1.7%. It wins every Cinebench test across R15, R20, and R23, in both multicore and single-core. The multithread PassMark score goes to AMD by 1.7%. For server or workstation workloads that rely on integer throughput, compression, physics simulation, or render workloads measured by Cinebench, the AMD part is the stronger choice.

The Intel Core Ultra 7 265 wins 4 benchmarks. Its largest win is floating point math at 44.2%. It also wins data encryption by 9.8% and PassMark single-thread by 12.2%. That 12.2% margin appears in both single-thread entries. For workloads dominated by floating point arithmetic, encryption tasks, or PassMark single-thread performance, the Intel part is the better option. Its higher memory bandwidth of 102.4 GB/s, compared to 83.2 GB/s for AMD, may also factor into memory-sensitive tasks, though no direct memory benchmark is recorded in this dataset.
