AMD Ryzen AI 9 365 vs Intel Core Ultra 9 285T Comparison

Head-to-Head Benchmarks

The recorded benchmark data shows a decisive sweep in favor of the Intel Core Ultra 9 285T, which wins all 15 head-to-head comparisons against the AMD Ryzen AI 9 365. The largest gaps appear in heavily multithreaded workloads, where the Intel part's higher core count and larger cache produce commanding leads. In Cinebench R23 multicore, the Intel chip scores 33,573 against AMD's 18,698, a delta of -44.3% for the Ryzen part. Cinebench R15 multicore shows a similar pattern, with Intel at 3,384 and AMD at 2,842, a 16% deficit. The Cinebench R23 single-core result is even more lopsided: Intel delivers 4,739 versus AMD's 1,992, a 58% difference. Cinebench R15 single-core follows with 477 against 303, a 36.5% gap.

The PassMark suite reinforces the pattern, though the margins vary by workload. The most extreme difference is in prime number finding, where Intel scores 345 versus AMD's 117, a 66.1% deficit for the Ryzen processor. Floating point math shows Intel at 137,923 against AMD's 62,802, a 54.5% gap. Data encryption leans heavily toward Intel as well, 32,061 versus 18,297, a 42.9% difference. Physics tests put Intel at 2,842 and AMD at 1,704, a 40% gap. The multithreaded PassMark score gives Intel 39,931 against AMD's 29,467, a 26.2% deficit. Integer math shows Intel at 132,433 versus AMD's 101,831, a 23.1% gap. Random string sorting favors Intel less strongly, 47,695 against 39,447, a 17.3% difference. Single-thread PassMark results place Intel at 4,576 and AMD at 3,841, a 16.1% gap. Data compression is the closest contest overall, with Intel at 384,140 and AMD at 354,510, a 7.7% deficit. Extended instructions also fall in Intel's favor, 27,477 versus 25,113, an 8.6% gap.

The average benchmark score places the Intel Core Ultra 9 285T at 51,310, compared to 40,048 for the AMD Ryzen AI 9 365. The Intel processor sits in the 91st percentile of all CPUs in the database, while the AMD part ranks in the 87th percentile.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen AI 9 365 uses the Zen 5 architecture with the Strix Point codename, built on a 4 nm process at TSMC. It has 10 cores and 20 threads, reflecting simultaneous multithreading. The Intel Core Ultra 9 285T uses the Arrow Lake architecture with the Arrow Lake-S codename, built on a 3 nm process, also at TSMC. It has 24 cores and 24 threads, with no multithreading per core. The Intel part carries 17,800 million transistors on a 243 mm² die, while the AMD part lists a 233 mm² die size with no transistor count in the database.

Cache configurations differ substantially. The AMD processor provides 80 KB of L1 per core, 1 MB of L2 per core, and 16 MB of L3 cache. The Intel processor provides 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3 cache. That larger shared L3 pool helps explain the Intel advantage in cache-sensitive workloads like data compression and random string sorting.

Memory support also diverges. The AMD chip supports DDR5 and LPDDR5X memory over a dual-channel bus, with a recorded memory bandwidth of 89.6 GB/s. The Intel chip supports DDR5 only, also dual-channel, but with a higher memory bandwidth of 102.4 GB/s. ECC memory is supported on the Intel part, while the AMD part does not list ECC support.

Connectivity differs as well. The AMD processor uses PCIe Gen 4 with 16 lanes (CPU only). The Intel processor uses PCIe Gen 5 with 20 lanes (CPU only). Integrated graphics differ: AMD pairs the CPU with the Radeon 880M, while Intel uses Arc Xe-LPG Graphics with 64 execution units.

The platform targets are different market segments. The AMD Ryzen AI 9 365 is a mobile processor using AMD Socket FP8, while the Intel Core Ultra 9 285T is a desktop processor using Intel Socket 1851. Neither processor has an unlocked multiplier. The AMD part released on 2024-06-30, while the Intel part released on 2025-01-06. The Intel chip has a launch MSRP of $549.

Where Each One Wins

The Intel Core Ultra 9 285T wins every recorded benchmark, so the use-case split is mostly about the degree of advantage rather than the direction. The largest Intel leads appear in workloads that scale with core count and cache capacity. Cinebench R23 multicore, prime number finding, floating point math, and data encryption all show Intel leads of roughly 43% to 66%. These tasks benefit from the 24-core configuration and the 36 MB of shared L3. The AMD Ryzen AI 9 365 still produces competitive numbers in some areas, but it trails by double digits in nearly every category.

The closest results for the AMD part are in data compression and extended instructions, where the Intel lead shrinks to 7.7% and 8.6%, respectively. These workloads may rely more on per-core efficiency and instruction-level parallelism, areas where the Zen 5 architecture remains respectable. Still, the Intel processor holds the advantage even there.

For single-threaded performance, the Intel part leads by 16.1% in PassMark single-thread and by 58% in Cinebench R23 single-core. The Cinebench R23 single-core gap is unusually large and suggests a significant clock and IPC difference in that specific workload. The Intel boost clock is 5.40 GHz versus 5.00 GHz for AMD, and the Intel part has a 1.40 GHz base clock versus 2.00 GHz for AMD.

The AMD processor does have some structural advantages that are not reflected in the benchmark list. It supports LPDDR5X memory, which is common in mobile platforms, and its 28 W TDP is lower than the Intel part's 35 W TDP. The AMD part also uses a smaller process node at 4 nm versus 3 nm, though both are TSMC fabs. For mobile deployment, the AMD chip's lower TDP and mobile socket could be more relevant than raw benchmark scores. The Intel part, as a desktop processor with a 35 W TDP, targets compact desktop systems where power is less constrained.
