AMD Ryzen 7 9850X3D vs Intel Core Ultra 7 265H Comparison

Head-to-Head Benchmarks

The recorded benchmark data shows a decisive overall advantage for the AMD Ryzen 7 9850X3D, which wins 13 of the 15 head-to-head comparisons. The Intel Core Ultra 7 265H takes only two wins, both in specialized workloads. The average benchmark scores reflect the gap: the AMD part scores 58386, while the Intel part records 41621, a difference that places them 92nd and 88th percentile respectively among all CPUs in the database.

Starting with the largest margins, the AMD Ryzen 7 9850X3D dominates in extended instruction throughput. In Passmark extended instructions, the AMD scores 39272 against Intel's 26805, a 46.5% advantage. Integer math shows a similar pattern: 123140 versus 85479, a 44.1% lead for AMD. Data compression is also heavily one-sided, with AMD at 474501 against Intel's 334711, a 41.8% gap. These three results indicate that the AMD processor handles compute-heavy integer and compression workloads with substantially more headroom.

The widest single delta in the entire comparison appears in Passmark physics. AMD records 4171, Intel records 2497, and the delta is 67% in favor of AMD. This result stands out as the most extreme performance difference between the two processors. The physics workload likely stresses memory latency and cache hierarchy, areas where the AMD part's large shared L3 cache provides a measurable benefit.

Multi-threaded rendering also favors AMD, though by smaller margins. In Cinebench R23 multi-core, AMD scores 22807 versus Intel's 19940, a 14.4% lead. Cinebench R15 multi-core shows an 18.8% gap (3551 against 2989). Cinebench R23 single-core is closer: AMD at 2228, Intel at 2080, a 7.1% difference. Cinebench R15 single-core shows 343 versus 307, an 11.7% advantage for AMD.

The Intel Core Ultra 7 265H's two wins are notable for their specificity. In Passmark floating point math, Intel scores 109123 against AMD's 81998, a 24.9% lead. This is the largest margin Intel achieves anywhere in the comparison. The other Intel win comes in data encryption, where Intel records 26005 against AMD's 22856, a 12.1% advantage. These results suggest that Intel's architecture has strengths in vectorized floating-point operations and cryptographic workloads, but those strengths do not translate into broader multi-threaded victories.

Other head-to-head results all go to AMD. Passmark multithread shows 41318 versus 34027, a 21.4% margin. Random string sorting favors AMD 49764 to 40742, a 22.1% gap. Prime number finding shows AMD at 435 versus Intel's 335, a 29.9% difference. Single-thread Passmark results give AMD 4704 against Intel's 4334, an 8.5% lead.

The Intel part's nearest rivals in the database include the Intel Core i7-14650HX with a delta of 0.1% and the AMD Ryzen 9 5900X with a delta of 0.6%. The AMD part's nearest rivals include the Intel Core i9-14900 at 0.5% and the AMD Ryzen AI 9 HX 470 at -0.7%. These proximity values place both processors in competitive company, though the absolute score difference between them is substantial.

The Verdict

The data points to two distinct usage profiles. The AMD Ryzen 7 9850X3D is the stronger processor for almost every measured workload, particularly those involving integer math, compression, physics simulation, and multi-threaded rendering. Its 13 wins against 2 losses, combined with an average benchmark score roughly 40% higher, make it the clear choice for compute-intensive tasks on a desktop platform.

The Intel Core Ultra 7 265H, with its 28 TDP and mobile BGA socket, fits a different role. Its floating-point math win (24.9%) and data encryption win (12.1%) indicate specific strengths in workloads that rely on vector arithmetic and cryptographic operations. For users targeting those particular tasks in a mobile form factor, the Intel part holds an edge. However, the overall benchmark record shows that the AMD processor outperforms it across the broad majority of tests, including single-thread and multi-thread workloads that typically define general-purpose performance.

Percentile rankings reinforce this verdict. The AMD part sits at the 92nd percentile, the Intel part at the 88th. While both are above average, the AMD processor's position is measurably higher in the overall distribution.
