Where Each One Wins

The Intel Core Ultra 9 285H claims 11 benchmark wins out of 17 head-to-head tests. Its dominance is most pronounced in floating-point workloads, physics simulations, and prime number finding. The PassMark floating point math score of 109,190 crushes the AMD result of 58,965, a 46% advantage. The physics test also shows a massive gap: 2,513 versus 1,389, a 44.7% lead for Intel. Prime number finding is particularly lopsided, with Intel scoring 330 against AMD's 87, a 73.6% difference. These results indicate the Intel part has a strong edge in compute-heavy, mathematically intensive tasks. The Core Ultra 9 also wins in PassMark multi-thread (34,171 versus 28,572), data encryption (26,140 versus 20,487), and extended instructions (26,794 versus 25,434). Single-thread performance also favors Intel in PassMark, with a 4,415 score versus 3,762.

The AMD Ryzen 7 PRO 8845HS wins 6 tests, and its victories are concentrated in specific areas. The most striking win is Cinebench R23 single-core, where AMD scores 3,468 against Intel's 2,129.5, a 62.9% advantage. This is an enormous gap in that particular test. AMD also wins Cinebench R23 multi-core (24,565 versus 20,781.5, an 18.2% lead) and Cinebench R15 single-core (349 versus 313, an 11.5% lead). In integer math, AMD scores 97,625 versus 85,922 for Intel, a 13.6% advantage. Data compression (343,952 versus 335,859) and random string sorting (41,867 versus 40,931) are close AMD wins, with margins of 2.4% and 2.3% respectively. The AMD chip is the better choice for workloads that rely on integer operations, compression, and sorting, along with the Cinebench R23 suite.

Architecture Differences

The AMD Ryzen 7 PRO 8845HS is built on the Zen 4 architecture, codenamed Hawk Point. It uses a 4 nm process node from TSMC and contains 25,000 million transistors on a 178 mm² die. The Intel Core Ultra 9 285H uses the Arrow Lake architecture, codenamed Arrow Lake-H, on a smaller 3 nm TSMC process node. Intel's transistor count and die size are not recorded in the database.

Cache layouts differ substantially between the two. The AMD part has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Intel part has 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 24 MB of shared L3 cache. The larger per-core L1 and L2 caches on the Intel side reflect its different core design, while the overall L3 pool is also larger.

Memory support shows another architectural split. The AMD chip supports DDR5 memory in a dual-channel configuration. The Intel chip supports both DDR5 and LPDDR5X, also in dual-channel. Memory bandwidth is higher on Intel at 102.4 GB/s versus 89.6 GB/s for AMD. Both processors support ECC memory. PCIe capabilities differ: AMD offers Gen 4 with 20 lanes (CPU only), while Intel offers Gen 5 with 8 lanes (CPU only).

Integrated graphics also differ. The AMD Ryzen 7 PRO 8845HS carries the Radeon 780M, while the Intel Core Ultra 9 285H carries the Arc Graphics 140T. Neither processor has an unlocked multiplier, and both are mobile market segments. The AMD processor uses the AMD Socket FP7, while Intel uses the Intel BGA 2049 socket.

Specification Differences

The core and thread counts are a major differentiator. AMD has 8 cores and 16 threads; Intel has 16 cores and 16 threads. Both are active production mobile parts. The AMD base clock is 3.80 GHz versus 2.90 GHz for Intel. The Intel boost clock is higher at 5.40 GHz versus 5.10 GHz for AMD. Both have a 45 W TDP.

The process node differs: AMD uses 4 nm TSMC, Intel uses 3 nm TSMC. The AMD die size is 178 mm², and the transistor count is 25,000 million; neither is recorded for Intel. The AMD part has 64 KB L1 and 1 MB L2 per core, while Intel has 192 KB L1 and 3 MB L2 per core. L3 cache is 16 MB shared for AMD and 24 MB shared for Intel.

Memory support: AMD lists DDR5 only, Intel lists DDR5 and LPDDR5X. Memory bandwidth is 89.6 GB/s for AMD and 102.4 GB/s for Intel. Both support ECC. PCIe generation differs: AMD is Gen 4 with 20 lanes, Intel is Gen 5 with 8 lanes. Integrated graphics are Radeon 780M for AMD and Arc Graphics 140T for Intel. The AMD part has a release date of 2024-04-15, while the Intel part has a release date of 2025-01-12. The Intel part has a launch MSRP of $651; no launch MSRP is recorded for AMD. The AMD part number is listed as 100-000001316(FP7r2),100-000001387(FP7), while Intel's is SRQAL.

Head-to-Head Benchmarks

The largest single benchmark margin is in Cinebench R23 single-core, where the AMD Ryzen 7 PRO 8845HS scores 3,468 versus 2,129.5 for the Intel Core Ultra 9 285H. That is a 62.9% advantage for AMD, and it is the single most decisive result in the comparison. The AMD chip also takes Cinebench R23 multi-core with 24,565 versus 20,781.5, an 18.2% lead. In Cinebench R15 single-core, AMD wins 349 to 313, an 11.5% margin.

The Intel Core Ultra 9 285H dominates the PassMark suite. Floating point math is its largest win: 109,190 versus 58,965, a 46% lead. Prime number finding shows a 73.6% gap in Intel's favor (330 versus 87). Physics simulation goes to Intel at 2,513 versus 1,389, a 44.7% edge. PassMark multi-thread favors Intel at 34,171 versus 28,572, a 16.4% difference. Data encryption is 26,140 versus 20,487, a 21.6% lead for Intel. PassMark single-thread is 4,415 versus 3,762, a 14.8% Intel advantage. Extended instructions are 26,794 versus 25,434, a 5.1% Intel win. Cinebench R20 multi-core goes to Intel at 12,201 versus 10,317, a 15.4% margin, and Cinebench R20 single-core also goes to Intel at 1,722 versus 1,456, another 15.4% margin. Cinebench R15 multi-core is Intel's at 3,177.5 versus 2,476, a 22.1% lead.

AMD's remaining wins are narrower. Integer math is 97,625 versus 85,922, a 13.6% advantage. Data compression is 343,952 versus 335,859, a 2.4% margin. Random string sorting is 41,867 versus 40,931, a 2.3% margin. The overall pattern is clear: Intel wins heavily in floating-point and throughput-heavy PassMark tests, while AMD wins decisively in the Cinebench R23 suite and modestly in integer, compression, and sorting workloads.

The Verdict

The data supports a split decision based on workload type. The Intel Core Ultra 9 285H is the stronger all-around performer in the PassMark benchmark family, winning multi-thread, single-thread, floating-point, physics, encryption, extended instructions, and prime number tests. Its 46% lead in floating point math and 44.7% lead in physics make it the clear choice for simulation, scientific computing, and any workload that leans heavily on floating-point throughput. The 16-core design, despite having the same thread count as the 8-core AMD part, delivers more raw compute in these scenarios. The Intel chip also has the higher boost clock at 5.40 GHz and the larger L3 cache at 24 MB.

The AMD Ryzen 7 PRO 8845HS is the pick for users whose workloads align with Cinebench R23. The 62.9% single-core advantage in that test is extraordinary, and the 18.2% multi-core lead reinforces its strength there. Integer math, data compression, and random string sorting also favor AMD, making it suitable for integer-heavy applications, archiving, and text processing. The AMD part has a higher base clock at 3.80 GHz and a smaller 4 nm process node, which may contribute to its efficiency in these tasks.

Both processors sit at the 86th percentile among all CPUs in the database. Their average benchmark scores are close: 39,325 for AMD versus 38,312 for Intel. The AMD chip's nearest rivals include the AMD Ryzen 7 PRO 8840HS at a 0.7% lower score and the AMD EPYC 4245P at a 0.3% higher score. The Intel chip's nearest rival is the Intel Core 9 270H at 0.1% lower, with the AMD Ryzen 7 250 at 0.2% higher. The overall performance class is similar, but the distribution of wins is not. Choose Intel for floating-point and physics-heavy tasks, choose AMD for Cinebench R23 and integer workloads. The launch MSRP of $651 for the Intel part is the only price data recorded.
