AMD Ryzen 7 PRO 8845HS vs Intel Core Ultra 9 285 Comparison

Head-to-Head Benchmarks

The benchmark data leaves no ambiguity: the Intel Core Ultra 9 285 wins every recorded head-to-head comparison against the AMD Ryzen 7 PRO 8845HS. Across all 17 matched tests, the Intel part holds the top score. The closest margin appears in single-threaded PassMark testing, where the Intel chip scores 4881 against 3762 for the AMD part, a 22.9% advantage. Every other test shows a larger gap.

Cinebench results are nearly uniform in their margin. In Cinebench R15 multicore, the Intel Core Ultra 9 285 scores 4933 versus 2476 for the Ryzen 7 PRO 8845HS, a 49.8% difference. The single-core R15 result is 696 versus 349, also a 49.9% gap. The same pattern holds in R20 and R23. The R20 multicore run shows 20556 against 10317 (49.8%), while the R23 multicore run shows 48945 against 24565 (49.8%). Single-core R20 is 2901 versus 1456 (49.8%), and single-core R23 is 6909 versus 3468 (49.8%). These consistent deltas suggest the performance difference scales evenly across both multicore and single-core workloads in Cinebench.

PassMark tests reveal where the Intel part stretches its lead furthest. The largest delta is in prime number finding, where the Intel Core Ultra 9 285 scores 459 against just 87 for the AMD chip, an 81% advantage. Floating point math is nearly as lopsided: 194988 versus 58965, a 69.8% gap. Physics simulation favors Intel by 61.4%, with scores of 3598 and 1389. Data encryption shows a 56.4% lead for Intel (46949 versus 20487). Multithreaded PassMark puts Intel ahead by 49.5% (56602 versus 28572). Extended instructions, random string sorting, and data compression all land in the 42.9% to 43.9% range. Integer math is the second-narrowest contest after single-thread PassMark, with Intel leading 164869 versus 97625, a 40.8% margin.

The overall average benchmark score tells the same story. The Intel Core Ultra 9 285 posts an average of 75488, while the AMD Ryzen 7 PRO 8845HS averages 39325. The Intel chip sits in the 95th percentile of all CPUs in the database; the AMD chip sits in the 86th percentile. The Intel part's nearest rivals by average score are all AMD server or workstation parts: the AMD EPYC 8224P (75582, 0.1% ahead of Intel), the AMD EPYC 4545P (75373, 0.2% behind), the AMD Ryzen 7 PRO 9755X3D (75716, 0.3% ahead), and the AMD Ryzen 7 PRO 9755 (75738, 0.3% ahead). The AMD Ryzen 7 PRO 8845HS, by contrast, sits near the Intel Core i7-13700F (39009, 0.8% behind AMD) and the AMD Ryzen 7 PRO 8840HS (39603, 0.7% ahead), with the AMD EPYC 4245P (39215, 0.3% behind) and AMD Ryzen AI 7 450 (39485, 0.4% ahead) also in its immediate neighborhood.

Architecture Differences

The two processors come from different design schools. The AMD Ryzen 7 PRO 8845HS uses Zen 4 architecture under the Hawk Point codename, built on a 4 nm process at TSMC. It packs 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 5.10 GHz. The Intel Core Ultra 9 285 uses Arrow Lake architecture (Arrow Lake-S), on a 3 nm process also from TSMC. It has 24 cores and 24 threads, with a base clock of 2.50 GHz and a boost clock of 5.60 GHz. The Intel part has three times the cores and a higher boost ceiling, though its base clock is lower.

Cache layouts differ sharply. The AMD chip has 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Intel chip has 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3. Both rely on DDR5 memory in a dual-channel configuration, but the Intel part carries a higher memory bandwidth rating of 102.4 GB/s versus 89.6 GB/s for the AMD chip. Both support ECC memory.

Transistor and die figures are notable. The AMD Ryzen 7 PRO 8845HS contains 25,000 million transistors on a 178 mm² die. The Intel Core Ultra 9 285 contains 17,800 million transistors on a larger 243 mm² die. Despite fewer transistors, the Intel chip uses a more advanced 3 nm process node.

PCIe connectivity differs by generation. The AMD part uses Gen 4 with 20 lanes (CPU only); the Intel part uses Gen 5 with 20 lanes (CPU only). Integrated graphics also differ: the AMD chip pairs with Radeon 780M, while the Intel chip uses Arc Xe-LPG Graphics 64EU.

The market segments diverge. The AMD Ryzen 7 PRO 8845HS is a mobile processor on AMD Socket FP7; the Intel Core Ultra 9 285 is a desktop processor on Intel Socket 1851. Release dates are roughly eight months apart, with the AMD part appearing on 2024-04-15 and the Intel part on 2024-12-31. Both are marked as active in production, and neither has an unlocked multiplier.

The Verdict

The data points to a clear separation in intended use. The Intel Core Ultra 9 285 dominates the AMD Ryzen 7 PRO 8845HS in every measured workload, with particularly large margins in floating point math, physics simulation, and prime number finding. Its 24 cores and 24 threads, higher boost clock, larger L3 cache, and higher memory bandwidth all align with its desktop positioning. The 95th percentile standing among all CPUs reinforces that it is a high-end desktop part.

The AMD Ryzen 7 PRO 8845HS is a mobile chip with 8 cores and 16 threads, a 45 W TDP, and a 4 nm process. Its 86th percentile ranking is respectable, but its nearest rivals are mainstream desktop and mobile parts, not flagship desktop silicon. The closest head-to-head margin, 22.9% in PassMark single-thread, still favors Intel by a wide margin, and the multi-threaded gaps are all near or above 40%.

For workloads that stress many cores, the Intel part's 24-core count makes the outcome predictable. For single-thread responsiveness, the Intel chip still leads, though by a smaller amount. The AMD part's strengths in this comparison are not visible in the benchmark scores, since it wins no recorded test. Its mobile socket, lower TDP, and earlier release date position it for laptops, while the Intel chip is firmly a desktop processor with a launch MSRP of $579. The recorded data indicates that the Intel Core Ultra 9 285 is the stronger processor in absolute terms, and the AMD Ryzen 7 PRO 8845HS should be evaluated within its mobile context rather than against desktop flagships.
