AMD Ryzen 7 PRO 9755X3D vs Intel Core Ultra 9 285 Comparison

The AMD Ryzen 7 PRO 9755X3D and Intel Core Ultra 9 285 represent two fundamentally different approaches to high-end desktop computing, and the benchmark data reflects this clearly. The Intel part wins the majority of the head-to-head comparisons, but the AMD processor secures a decisive victory in one specific workload category, making the choice highly dependent on the intended use case. The aggregate scores are remarkably close, with the AMD Ryzen 7 PRO 9755X3D posting an average benchmark score of 75,716 against the Intel Core Ultra 9 285's 75,488, a difference of just 0.3 percent.

Head-to-Head Benchmarks

The Intel Core Ultra 9 285 dominates the PassMark suite, winning 10 of the 11 head-to-head comparisons. The largest margin of victory comes in floating-point math, where the Intel part scores 194,988 against the AMD's 80,284, a delta of -58.8 percent. This is a substantial gap that indicates the Intel architecture has a significant advantage in workloads that rely heavily on floating-point calculations, such as scientific computing and certain rendering tasks. Similarly, in data encryption, the Intel processor scores 46,949 versus the AMD's 22,632, a -51.8 percent difference, suggesting a major throughput advantage in cryptographic operations.

The gap narrows considerably in other tests but remains firmly in Intel's favor. In random string sorting, the Intel Core Ultra 9 285 achieves 73,651 compared to the AMD Ryzen 7 PRO 9755X3D's 49,050, a -33.4 percent delta. Multithreaded performance also favors Intel, with a score of 56,602 against 40,474, representing a -28.5 percent difference. The integer math test shows a similar pattern: Intel scores 164,869 while AMD manages 119,404, a -27.6 percent gap. Data compression results show Intel ahead with 602,121 versus 469,207, a -22.1 percent difference.

The remaining Intel victories are more modest. Extended instructions see Intel at 45,357 against AMD's 38,436, a -15.3 percent delta. Single-thread performance, measured twice in the data, shows Intel scoring 4,881 against AMD's 4,443, a -9 percent difference. The find prime numbers test is extremely close, with Intel scoring 459 to AMD's 451, a marginal -1.7 percent delta. These results suggest that while Intel holds a lead across most workloads, the margin is not uniform, with the largest gaps appearing in highly parallel or specialized instruction tasks.

The AMD Ryzen 7 PRO 9755X3D's sole victory comes in the physics test, where it scores 4,056 against Intel's 3,598, a 12.7 percent advantage. This is a notable win for AMD, as it indicates the processor handles physics-based calculations more efficiently than the Intel part, likely due to its higher base clock of 4.70 GHz versus Intel's 2.50 GHz, despite the Intel part having a higher boost clock of 5.60 GHz versus 5.20 GHz. While this is only one win, it is a significant one for users running physics simulations or gaming physics engines.

The Verdict

The data presents a clear picture: the Intel Core Ultra 9 285 is the stronger performer for the majority of benchmark workloads. With 10 wins out of 11 head-to-head tests and significant margins in floating-point math, encryption, and multithreaded tasks, it is the better choice for users who prioritize raw throughput across varied applications. The Intel part also benefits from a higher boost clock of 5.60 GHz and a much larger core count of 24 versus the AMD's 8, which explains its dominance in parallel workloads. The Intel Core Ultra 9 285 also has a higher single-thread score of 4,881 versus 4,443, making it the better option for lightly threaded tasks that depend on single-core speed.

However, the AMD Ryzen 7 PRO 9755X3D is not without merit. Its 12.7 percent lead in the physics test suggests it has a specialized capability that could be advantageous for specific simulation workloads. The AMD part also has a much larger L3 cache of 96 MB shared, compared to Intel's 36 MB shared, and a lower TDP of 120 watts versus Intel's 65 watts, though the Intel part is more power-efficient. The AMD processor also sports a higher base clock of 4.70 GHz, which may contribute to its physics performance. For users whose primary workload is physics-based, the AMD Ryzen 7 PRO 9755X3D offers a measurable advantage that the Intel part cannot match.

The average benchmark scores are nearly identical, with the AMD part at 75,716 and the Intel part at 75,488, a delta of just 0.3 percent. This means that for general-purpose computing, users are unlikely to notice a significant difference between the two. The choice ultimately hinges on workload profile: the Intel Core Ultra 9 285 is the safer bet for diverse, heavy multi-threaded tasks, while the AMD Ryzen 7 PRO 9755X3D is the targeted choice for physics-heavy applications. The Intel part’s launch MSRP is $579, which can be stated once for reference.
