AMD Ryzen AI 7 450 vs Intel Core Ultra 9 285T Comparison

The Verdict

The recorded data leaves no ambiguity: the Intel Core Ultra 9 285T wins every single head-to-head benchmark in the database, 15 wins to 0. Its average benchmark score of 51310 places it in the 91st percentile of all CPUs, while the AMD Ryzen AI 7 450 sits at 39485 and the 87th percentile. The magnitude of the gap varies by workload, from a modest 14.8% lead in single-thread PassMark to a massive 74.2% advantage in prime number finding.

The Intel part belongs to a different performance tier entirely. Its nearest rivals are the Intel Core i9-14900T (0.6% ahead), the Intel Core i9-13900F (0.8% behind), and the AMD Ryzen 9 5900XT (1.2% behind). The AMD Ryzen AI 7 450, by contrast, trades blows with the AMD Ryzen 7 PRO 8845HS (0.4% behind), the AMD EPYC 4245P (0.7% behind), and the AMD Ryzen 7 9800X3D (0.7% behind). The data shows two CPUs aimed at different segments: the Ryzen AI 7 450 is a mobile part, the Core Ultra 9 285T is a desktop part.

For users who need maximum multi-threaded throughput, Cinebench R23 multi-core shows the Intel at 33573 versus 18316 for the AMD, a 45.4% deficit. For users constrained by power or chassis space, the AMD's 28W TDP and mobile socket FP8 make it the only realistic option of the two, though its performance ceiling is far lower. The Core Ultra 9 285T carries a launch MSRP of $549; the Ryzen AI 7 450 has no recorded launch MSRP. The verdict from the data is simple: the Intel Core Ultra 9 285T is the faster processor in every measured category, and the AMD Ryzen AI 7 450 is the lower-power, mobile-oriented alternative.

Where Each One Wins

The Intel Core Ultra 9 285T wins in every category recorded in the database. There is no benchmark in the head-to-head set where the AMD Ryzen AI 7 450 takes the lead. The closest margin is PassMark single-thread, where Intel leads by 14.8% (4576 versus 3901). The largest margins appear in integer-heavy and math-heavy workloads: PassMark find prime numbers shows Intel ahead by 74.2% (345 versus 89), and floating-point math shows a 60.5% edge (137923 versus 54447).

The Intel part also dominates in rendering. Cinebench R23 single-core shows 4739 versus 2038, a 57% lead, and R23 multi-core shows 33573 versus 18316, a 45.4% lead. In data encryption, Intel scores 32061 versus 16247, a 49.3% gap. The AMD's only comparative strengths are relative, not absolute: its 8-core, 16-thread configuration with a 2.00 GHz base clock and 5.10 GHz boost is more power-efficient in specification, with a 28W TDP against Intel's 35W. But the benchmark data does not record a single workload where that efficiency translates into a performance win.

The use-case split is therefore defined by hardware constraints, not benchmark outcomes. The AMD Ryzen AI 7 450 uses AMD Socket FP8, a mobile platform, while the Intel Core Ultra 9 285T uses Intel Socket 1851, a desktop platform. The AMD supports LPDDR5X memory and DDR5, while the Intel supports DDR5 only, though Intel's memory bandwidth is higher at 102.4 GB/s versus 89.6 GB/s. The Intel has 24 cores and 24 threads, the AMD has 8 cores and 16 threads. The Intel's 36 MB of shared L3 cache dwarfs the AMD's 8 MB. Every architectural and benchmark advantage belongs to the Intel part.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen AI 7 450 uses Zen 5 architecture on a 4 nm TSMC process, with the codename Gorgon Point and the Ryzen AI 400 generation, which combines Zen 5 and Zen 5c cores. It is built for mobile, with an 8-core, 16-thread layout, a 2.00 GHz base clock, and a 5.10 GHz boost clock. Its cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3. The die size is 195 mm², and the integrated graphics are Radeon 860M.

The Intel Core Ultra 9 285T uses Arrow Lake architecture on a 3 nm TSMC process, with the codename Arrow Lake-S and the Core Ultra Series 2 generation. It is a desktop part with 24 cores and 24 threads, a 1.40 GHz base clock, and a 5.40 GHz boost clock. The cache hierarchy is far larger: 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3. The die size is 243 mm², and Intel lists 17,800 million transistors. The integrated graphics are Arc Xe-LPG Graphics 64EU.

The process node difference is small (4 nm versus 3 nm, both TSMC), but the core count difference is enormous: 24 cores versus 8. The Intel part has no hyper-threading, hence 24 threads for 24 cores, while the AMD uses simultaneous multithreading to reach 16 threads from 8 cores. The Intel's 5.40 GHz boost clock is higher than the AMD's 5.10 GHz, and its 36 MB of shared L3 is 4.5 times larger than the AMD's 8 MB. The Intel part also supports PCIe Gen 5 with 20 lanes, while the AMD supports PCIe Gen 4 with 16 lanes. Both support ECC memory and dual-channel memory buses. The TDP difference is notable: 35W for Intel versus 28W for AMD, but the Intel delivers dramatically more performance per the benchmark scores despite the higher power envelope.

Head-to-Head Benchmarks

The head-to-head benchmark data is comprehensive, with 15 recorded comparisons, all won by the Intel Core Ultra 9 285T. The largest single gap is in PassMark find prime numbers, where Intel scores 345 against AMD's 89, a 74.2% difference. This workload is highly integer-sensitive, and Intel's core count advantage shows clearly. The second-largest gap is in PassMark floating-point math, where Intel scores 137923 versus 54447, a 60.5% lead. These two results indicate that the Intel part is not just faster in aggregate, but specifically dominant in math-heavy compute.

The rendering benchmarks tell a similar story. Cinebench R23 single-core shows Intel at 4739 versus AMD's 2038, a 57% gap. Cinebench R23 multi-core shows Intel at 33573 versus 18316, a 45.4% gap. The older Cinebench R15 results are also Intel wins: 3384 versus 2713 in multi-core (19.8% gap) and 477 versus 215 in single-core (54.9% gap). The single-core Cinebench R15 gap is striking because the AMD's boost clock of 5.10 GHz is close to Intel's 5.40 GHz, yet Intel still wins by more than half.

Data-centric workloads follow the same pattern. PassMark data encryption shows Intel at 32061 versus AMD's 16247, a 49.3% gap. PassMark data compression shows Intel at 384140 versus 315906, a 17.8% gap. PassMark extended instructions shows Intel at 27477 versus 22400, an 18.5% gap. PassMark random string sorting shows Intel at 47695 versus 35648, a 25.3% gap.

The remaining PassMark results reinforce the Intel advantage. PassMark integer math: Intel 132433 versus AMD 88531, a 33.2% gap. PassMark multithread: Intel 39931 versus AMD 26350, a 34% gap. PassMark physics: Intel 2842 versus AMD 1578, a 44.5% gap. PassMark single-thread: Intel 4576 versus AMD 3901, a 14.8% gap, the closest result in the entire comparison.

The database also records the AMD's standalone benchmarks, which show respectable absolute numbers: a Cinebench R23 multi-core score of 18316, a PassMark multithread score of 26350, and a single-thread PassMark score of 3901. But against the Intel Core Ultra 9 285T, every one of those numbers falls short. The Intel part's nearest rivals in the database are other high-end desktop processors, while the AMD's nearest rivals are mobile and workstation parts of similar average score. The data confirms that the Intel Core Ultra 9 285T is the dominant processor in this pairing across every measured workload.
