Where Each One Wins

The Intel Core Ultra 9 285H dominates every category except one. For multi-threaded productivity, the data shows consistent Intel advantages across Cinebench R15 and R23 multi-core, PassMark multi-thread, data compression, and random string sorting. The margins range from 12.4% to 27.5%. For floating point arithmetic, encryption, physics, and extended instruction workloads, the Intel chip is dramatically faster, with margins from 22.5% to 74.5%. Single-thread performance also favors Intel, though the Cinebench R23 margin is modest at 5.6%.

The AMD Ryzen AI 7 PRO 450 wins only integer math. The 0.4% margin is negligible in practical terms, but it does represent a specific workload where the AMD architecture holds a slight edge. No other benchmark in the database records an AMD victory. The AMD chip's closest performance parity appears in Cinebench R23 single-core, where the 5.6% gap is the smallest Intel advantage outside of integer math.

For users whose workloads rely on integer operations, the AMD chip is nominally superior. For everything else, the Intel part delivers substantially higher scores. The data does not show any other use case where the AMD product closes the gap to single-digit percentages.

Specification Differences

The two processors differ in core count, clock speeds, power envelope, socket, process node, cache configuration, PCIe generation, memory bandwidth, integrated graphics, and release date.

The AMD Ryzen AI 7 PRO 450 has 8 cores and 16 threads. The Intel Core Ultra 9 285H has 16 cores and 16 threads. The AMD chip's base clock is 2.00 GHz and its boost clock is 5.10 GHz. The Intel chip's base clock is 2.90 GHz and its boost clock is 5.40 GHz. The AMD part carries a 28 W TDP, while the Intel part is rated at 45 W.

The AMD processor uses AMD Socket FP8, while the Intel processor uses Intel BGA 2049. The AMD chip has a 4 nm process node, the Intel chip a 3 nm node. Both are fabricated by TSMC. The AMD die size is 195 mm², while the Intel die size is not recorded.

Cache configurations differ substantially. The AMD chip has 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3. The Intel chip has 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3. Both support DDR5 and LPDDR5X memory with dual-channel buses. The AMD memory bandwidth is 89.6 GB/s, while the Intel memory bandwidth is 102.4 GB/s. Both support ECC memory.

PCIe support differs: the AMD chip uses Gen 4 with 16 lanes (CPU only), while the Intel chip uses Gen 5 with 8 lanes (CPU only). Integrated graphics also differ: the AMD chip has Radeon 860M, the Intel chip has Arc Graphics 140T. The AMD chip was released on 2026-01-04, while the Intel chip was released on 2025-01-12. The Intel part has a recorded launch MSRP of $651; the AMD part has no recorded launch MSRP.

Architecture Differences

The AMD Ryzen AI 7 PRO 450 is built on the Zen 5 architecture under the Gorgon Point codename, belonging to the Ryzen AI PRO 400 generation that combines Zen 5 and Zen 5c cores. The Intel Core Ultra 9 285H uses the Arrow Lake architecture under the Arrow Lake-H codename, belonging to the Ultra 9 generation within Arrow Lake-H.

The process nodes differ: AMD uses 4 nm, Intel uses 3 nm, both from TSMC. The core counts reflect different design philosophies: AMD provides 8 cores with simultaneous multithreading for 16 threads, while Intel provides 16 physical cores without hyperthreading, also yielding 16 threads. The Intel part therefore relies on raw core count rather than multithreading to reach its thread count.

Cache hierarchy differs significantly. The AMD part uses 80 KB L1 per core, 1 MB L2 per core, and 8 MB of L3. The Intel part uses 192 KB L1 per core, 3 MB L2 per core, and 24 MB of shared L3. The Intel chip has 3 times the L3 capacity and larger per-core L1 and L2 allocations. This cache advantage likely contributes to the Intel chip's higher single-thread scores and its lead in data compression and encryption tests.

The Intel chip's 45 W TDP versus the AMD's 28 W TDP indicates a higher power envelope, which aligns with its higher clock speeds (5.40 GHz boost versus 5.10 GHz) and larger core count. The Intel part also supports PCIe Gen 5 (8 lanes) versus AMD's PCIe Gen 4 (16 lanes). Memory bandwidth favors Intel at 102.4 GB/s versus 89.6 GB/s.

The integrated graphics solutions differ: Radeon 860M on the AMD side versus Arc Graphics 140T on the Intel side. The database does not record integrated graphics benchmark scores, so no performance comparison is possible from the data. The release dates place the Intel part roughly a year earlier, with the AMD part arriving in early 2026.

The Verdict

The benchmark data supports a clear conclusion: the Intel Core Ultra 9 285H is the faster processor in nearly every measured workload. With 14 wins out of 15 head-to-head tests, the Intel chip leads by margins ranging from 5.6% (Cinebench R23 single-core) to 74.5% (PassMark find prime numbers). The average benchmark score confirms the hierarchy: Intel at 38312 versus AMD at 37093, with the Intel part at the 86th percentile and the AMD part at the 85th percentile.

The AMD Ryzen AI 7 PRO 450 offers one specific advantage: integer math performance, where it beats the Intel chip by 0.4%. This margin is statistically negligible and does not offset the Intel chip's advantages elsewhere. The AMD chip's closest competition appears in single-core Cinebench R23, where the 5.6% gap is the smallest Intel lead in the dataset.

For workloads involving floating point arithmetic, prime number calculations, physics simulation, data encryption, or multi-threaded rendering, the Intel Core Ultra 9 285H is substantially ahead, often by 40% or more. For single-threaded tasks and general productivity, the Intel chip still leads, though the margin narrows to single digits in one test.

The specification differences explain the performance gap. The Intel chip has 16 physical cores versus the AMD's 8 cores with multithreading, a 3 nm process versus 4 nm, 24 MB of L3 versus 8 MB, higher clocks (5.40 GHz versus 5.10 GHz), higher memory bandwidth (102.4 GB/s versus 89.6 GB/s), and a higher TDP (45 W versus 28 W). The Intel chip's release date is earlier, and it carries a launch MSRP of $651.

The database records no benchmark where the AMD chip wins multi-threaded, single-threaded, or specialty workloads beyond integer math. Users requiring maximum multi-core throughput, encryption performance, or floating point capability should select the Intel part based on the recorded data. Users with integer-heavy workloads may consider the AMD chip, but the 0.4% margin provides little practical benefit. The overall average scores place the Intel chip 3.2% higher, which aligns with its wider lead across most tests.
