AMD Ryzen AI 9 HX PRO 375 vs Intel Core Ultra 9 285 Comparison

Head-to-Head Benchmarks

The benchmark data records a decisive sweep: Intel Core Ultra 9 285 wins all 17 head-to-head comparisons against AMD Ryzen AI 9 HX PRO 375. No single test favors the AMD part. The margins vary widely, from a narrow single-thread gap to dominant multi-core and math workload leads.

In Cinebench tests, the pattern is consistent. The Intel part scores 4933 in Cinebench R15 multi-core versus 2875 for AMD, a delta of -41.7% from the AMD perspective. The R15 single-core test shows 696 against 405, also -41.7%. Cinebench R20 multi-core repeats the -41.7% delta: 20556 versus 11982. R20 single-core: 2901 versus 1691. The gap holds through Cinebench R23, where Intel posts 48945 multi-core and 6909 single-core, while AMD posts 28529 and 4027 respectively. Every Cinebench result lands at the same -41.7% delta, indicating a consistent performance ratio across rendering workloads.

PassMark results show a broader spread. The largest single deficit for AMD appears in PassMark find prime numbers, where Intel scores 459 against AMD's 125, a -72.8% delta. Floating point math shows Intel at 194988 versus AMD's 74626, a -61.7% gap. Data encryption favors Intel at 46949 versus 21186, a -54.9% delta. Physics testing gives Intel 3598 against AMD's 1843, a -48.8% margin. PassMark multi-thread records 56602 for Intel and 33689 for AMD, a -40.5% delta. Random string sorting shows 73651 versus 45358, a -38.4% gap. Extended instructions: 45357 versus 29351, -35.3%. Data compression: 602121 versus 416331, -30.9%. Integer math closes the range: Intel 164869 versus AMD 119521, a -27.5% delta. Even the closest test, PassMark single-thread, gives Intel 4881 against AMD's 3914, a -19.8% margin.

The average benchmark score reinforces the separation. Intel Core Ultra 9 285 holds an avgBenchmarkScore of 75488, while AMD Ryzen AI 9 HX PRO 375 sits at 47022. That places Intel at the 95th percentile among all CPUs in the database; AMD sits at the 89th percentile. The nearest rivals for Intel are server-class AMD EPYC parts: EPYC 8224P at 75582 (-0.1%), EPYC 4545P at 75373 (+0.2%), Ryzen 7 PRO 9755X3D at 75716 (-0.3%), and Ryzen 7 PRO 9755 at 75738 (-0.3%). AMD's nearest rivals are desktop chips from both vendors: Ryzen 9 5900 at 46971 (+0.1%), Core i7-13700K at 46881 (+0.3%), Core i9-12900F at 47176 (-0.3%), and Core i7-13700KF at 47330 (-0.6%). These clusters show that the Ryzen AI 9 HX PRO 375 competes with prior-generation high-end desktop parts, while the Core Ultra 9 285 operates in a higher tier entirely.

Where Each One Wins

The recorded data shows no benchmark category where the AMD processor takes the lead. Every workload represented in the head-to-head table, from Cinebench rendering to PassMark math, encryption, compression, sorting, and single-thread tests, records an Intel victory.

The Intel part's strongest relative advantages come in prime number finding, floating point math, and encryption. These workloads place heavy demands on raw compute throughput, and the data confirms Intel's advantage widens there. The -72.8% delta in find prime numbers is the largest gap in the dataset, followed by -61.7% in floating point math and -54.9% in data encryption.

The AMD part's closest margin is in single-thread performance, where the -19.8% delta is the smallest of any test. That indicates the Ryzen AI 9 HX PRO 375 is comparatively stronger in lightly threaded work, though still behind. The integer math test also shows a relatively smaller gap at -27.5%, suggesting AMD's per-core integer throughput is less disadvantaged than its floating point or encryption throughput.

For use-case segmentation, the data points to Intel for any workload that scales with core count or heavy math. The Cinebench multi-core results at -41.7% across all three versions reflect consistent rendering performance differences. Intel also leads in data compression at -30.9%, which matters for archiving and storage-heavy tasks. The only area where AMD comes within 20% of Intel is single-thread performance; all other tests show deficits of 27% or more.

Architecture Differences

The two processors differ substantially in core configuration, process technology, and platform features. AMD Ryzen AI 9 HX PRO 375 uses 12 cores and 24 threads, built on Zen 5 architecture with the Strix Point codename. The generation field lists "Ryzen AI PRO 300 (Zen 5 / Zen 5c)", indicating a hybrid core arrangement. Intel Core Ultra 9 285 uses 24 cores and 24 threads, based on Arrow Lake architecture with the Arrow Lake-S codename. Intel's chip has no simultaneous multithreading, hence 24 threads from 24 cores, while AMD's 12 cores produce 24 threads.

Process nodes differ: AMD uses a 4 nm process from TSMC with a die size of 233 mm². Intel uses a 3 nm process, also from TSMC, with a die size of 243 mm². Intel's transistor count is listed at 17,800 million; AMD's transistor count is not recorded in the database.

Clock speeds show Intel at 2.50 GHz base and 5.60 GHz boost, versus AMD at 2.00 GHz base and 5.10 GHz boost. Thermal design power differs sharply: Intel is rated at 65 W, AMD at 28 W. This aligns with their market segments: Intel is a desktop part on Socket 1851, while AMD is a mobile part on AMD Socket FP8.

Cache hierarchies diverge significantly. AMD provides 80 KB L1 per core, 1 MB L2 per core, and 16 MB L3. Intel provides 192 KB L1 per core, 3 MB L2 per core, and 36 MB shared L3. The Intel chip carries more than double the L3 capacity. Memory support: AMD lists DDR5 and LPDDR5X with dual-channel bus and 89.6 GB/s bandwidth. Intel lists DDR5 only, dual-channel, at 102.4 GB/s bandwidth. Both support ECC memory.

PCIe connectivity also differs: AMD offers Gen 4 with 16 lanes (CPU only), while Intel offers Gen 5 with 20 lanes (CPU only). Integrated graphics differ as well: AMD uses Radeon 890M, Intel uses Arc Xe-LPG Graphics 64EU. AMD's part number is 100-000001683, Intel's is SRQD4. Neither processor has an unlocked multiplier.

Release dates are close: AMD released 2025-01-05, Intel released 2024-12-31. Intel lists a launch MSRP of $579; AMD does not have a recorded launch MSRP. Intel's production status is Active, as is AMD's. Intel's series is Core Ultra Series 2, while AMD's series field is null in the database.

The Verdict

The recorded data supports a clear choice for users who prioritize raw performance: Intel Core Ultra 9 285 wins every benchmark in the comparison set. Its avgBenchmarkScore of 75488 places it at the 95th percentile, and its nearest rivals are server-grade EPYC processors. The Ryzen AI 9 HX PRO 375, with an avgBenchmarkScore of 47022 at the 89th percentile, sits alongside desktop parts like the Ryzen 9 5900 and Core i7-13700K.

For rendering workloads, Cinebench R23 multi-core shows Intel at 48945 versus AMD's 28529. For math-heavy tasks, PassMark floating point shows Intel at 194988 versus AMD's 74626. For encryption, Intel at 46949 versus 21186. These are not marginal differences; they range from roughly 27% to 73% depending on the test.

The AMD part's case rests on platform positioning rather than benchmark wins. It is a mobile processor with a 28 W TDP, whereas Intel is a desktop processor with a 65 W TDP. The database shows no performance category where AMD leads, so any selection of the Ryzen AI 9 HX PRO 375 would depend on system-level factors such as mobility and power envelope, not on the head-to-head results recorded here.

The data also shows that Intel's single-thread advantage, while still decisive at -19.8%, is the smallest gap. Users whose workloads are primarily single-threaded would still get better performance from Intel, but the margin narrows compared to multi-threaded or math-intensive tasks.

In summary, the benchmark database records Intel Core Ultra 9 285 as the superior performer across all 17 head-to-head tests. The AMD Ryzen AI 9 HX PRO 375 remains competitive only in the sense that its closest deficits are in single-thread and integer math workloads, where the gap is smallest. For any metric in the dataset, Intel delivers the higher score.
