AMD Ryzen 5 7500X3D vs Intel Core Ultra 9 285H Comparison

Head-to-Head Benchmarks

The comparison between the AMD Ryzen 5 7500X3D and the Intel Core Ultra 9 285H is lopsided in raw compute, but the single AMD victory reveals a meaningful specialization. The Intel part wins 10 of the 11 shared PassMark tests, while the AMD chip takes only the physics test. The magnitude of Intel's wins varies widely, from a modest 17.6% margin to a dominant 60.1% blowout.

The largest gap appears in floating-point math, where the Intel Core Ultra 9 285H scores 109190 against the AMD Ryzen 5 7500X3D's 43594. That is a 60.1% deficit for the AMD part, the steepest delta in the entire set. This result indicates that the Intel processor's wider execution resources and higher boost clock translate into a substantial advantage for workloads that rely on heavy FPU throughput. The AMD chip's 5 nm Raphael design, with its 96 MB of shared L3 cache, cannot compensate for the raw throughput difference in this test.

Data encryption shows the second-largest gap. Intel posts 26140 versus AMD's 15797, a 39.6% difference. Cryptographic workloads often depend on both instruction-level parallelism and clock speed, and the Intel chip's 5.40 GHz boost clock, compared to 4.50 GHz for the AMD part, helps explain the result. The AMD processor's 6 cores and 12 threads are simply outmatched by the Intel chip's 16 cores and 16 threads in this parallel-friendly workload.

Prime number finding reveals a 33% edge for Intel, with scores of 330 versus 221. Integer math is closer but still favors Intel: 85922 versus 70774, a 17.6% gap. The multi-threaded PassMark score follows a similar pattern, with Intel at 34171 and AMD at 25047, a 26.7% difference. The AMD chip's lower thread count, 12 versus 16, limits its ceiling in heavily threaded benchmarks, despite the large L3 cache.

Random string sorting goes to Intel by 19.4%, with scores of 40931 and 32999. Extended instructions favor Intel by 23.7%, and data compression by 19.1%. Single-thread performance, a critical metric for everyday responsiveness, shows Intel ahead by 20.9%: 4415 versus 3494. This single-thread margin is consistent across both duplicate PassMark single-thread entries in the database.

The one AMD win is in the physics benchmark. The Ryzen 5 7500X3D scores 2779, while the Core Ultra 9 285H scores 2513, giving AMD a 10.6% advantage. This is notable because physics simulations in the PassMark suite often reward cache hierarchy and memory latency behavior. The AMD chip's 96 MB of shared L3 cache, built on the Raphael architecture with 3D V-Cache technology, likely provides the low-latency data access that this workload demands. The Intel part's 24 MB of shared L3 cannot match that capacity.

The average benchmark scores reflect the overall balance. The AMD Ryzen 5 7500X3D carries an average score of 44573 across its benchmark set, placing it in the 89th percentile of all CPUs in the database. The Intel Core Ultra 9 285H averages 38312, which lands in the 86th percentile. However, these averages are not directly comparable because the two processors were tested on different benchmark suites; the Intel part includes Cinebench R15, R20, R23, and Geekbench results, while the AMD part only lists PassMark tests. Within the shared PassMark tests, Intel wins decisively.

The nearest rivals in the database provide context for each chip's standing. The AMD Ryzen 5 7500X3D sits within 0.7% of the Intel Core i5-14600, which scores 44889, and within 0.2% of the Intel Core Ultra X9 388H at 44466. It also edges out the Intel Core i9-13950HX by 0.5% and the AMD Ryzen AI Max 385 by 0.6%. The Intel Core Ultra 9 285H, by contrast, trades places with the Intel Core 9 270H (38335, a 0.1% gap) and the AMD Ryzen 7 250 (38221, a 0.2% gap). These close rivalries suggest that both chips are competitively positioned within their respective performance tiers, even though the head-to-head results favor Intel heavily.

The Verdict

The data points to two distinct usage profiles. The Intel Core Ultra 9 285H is the clear choice for compute-heavy workloads that scale with core count and clock speed. Its wins in floating-point math, encryption, integer math, and multi-threaded PassMark make it the stronger processor for rendering, scientific computation, and data processing. The 16-core, 16-thread configuration with a 5.40 GHz boost clock delivers consistently higher throughput across most measured tasks.

The AMD Ryzen 5 7500X3D is the better option for physics-based simulations, as demonstrated by its 10.6% win in the PassMark physics benchmark. This advantage likely stems from the 96 MB shared L3 cache, which excels at keeping frequently accessed data close to the cores. For users whose primary workload involves physics calculations or cache-sensitive simulations, the AMD chip offers a measurable benefit despite losing most other tests.

The percentile data complicates a simple recommendation. The AMD part ranks in the 89th percentile overall, three points above the Intel chip's 86th percentile, and its average benchmark score of 44573 exceeds Intel's 38312. Yet the head-to-head tests tell a different story. The discrepancy arises because the two chips were evaluated on overlapping but not identical benchmark sets. The Intel part's Cinebench and Geekbench results drag its average down relative to its PassMark performance, while the AMD chip's average reflects only its PassMark scores.

In practical terms, the Intel Core Ultra 9 285H delivers superior performance in the majority of shared tests, with margins ranging from 17.6% to 60.1%. The AMD Ryzen 5 7500X3D offers a single, targeted advantage in physics workloads. The choice depends entirely on whether the user's application mix values the Intel chip's broad compute dominance or the AMD chip's specialized cache-driven physics performance.
