For users whose workloads rely on floating-point calculations, encryption, prime number searches, or single-thread responsiveness, the Intel Core Ultra 5 225H is the stronger choice.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI 7 PRO 450 uses the Zen 5 architecture under the Gorgon Point codename, built on TSMC's 4 nm process with a 195 mm² die. It packs 8 cores and 16 threads, leveraging simultaneous multithreading to double thread count. The Intel Core Ultra 5 225H uses the Arrow Lake architecture under the Arrow Lake-H codename, built on TSMC's 3 nm process, with 14 cores and 14 threads, meaning no hyperthreading on this part.

Cache layouts differ significantly. The AMD chip provides 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3 cache. The Intel chip offers 192 KB of L1 per core, 3 MB of L2 per core, and a much larger 18 MB shared L3 cache. The larger per-core L1 and L2 on the Intel part likely contribute to its single-thread and floating-point advantages, while the AMD chip relies on higher clock speeds and simultaneous multithreading.

Clock speeds tell part of the story. The AMD Ryzen AI 7 PRO 450 has a base clock of 2.00 GHz and a boost clock of 5.10 GHz. The Intel Core Ultra 5 225H has a lower base clock of 1.70 GHz and a boost clock of 4.90 GHz. Both processors share the same 28 W TDP and are unlocked multipliers set to false, so neither allows overclocking.

Memory support is similar on both platforms: DDR5 and LPDDR5X with dual-channel buses. However, the Intel part provides higher memory bandwidth at 102.4 GB/s versus AMD's 89.6 GB/s. The AMD chip supports ECC memory, while the Intel chip does not. PCIe connectivity also differs, with AMD using Gen 4 across 16 CPU lanes and Intel using Gen 5 across 8 CPU lanes.

The integrated graphics differ as well. AMD pairs the Ryzen AI 7 PRO 450 with the Radeon 860M, while Intel equips the Core Ultra 5 225H with Arc Graphics 130T. Both target the mobile market segment and remain in active production. The AMD part released on 2026-01-04, while the Intel part shipped earlier on 2025-01-12.

Process node differences matter here: Intel uses TSMC's 3 nm process while AMD uses 4 nm. The Intel part also carries a significantly larger L3 cache, which may explain its strong showing in cache-sensitive workloads like encryption and random string sorting. The AMD part's higher boost clock of 5.10 GHz versus 4.90 GHz helps explain its Cinebench multi-core wins despite having fewer physical cores.

Head-to-Head Benchmarks

The largest single victory in this comparison belongs to the Intel Core Ultra 5 225H in PassMark find prime numbers. The Intel part scores 220 against AMD's 84, a massive 61.8% delta. This result indicates the Intel architecture handles this specific integer-heavy algorithm with far greater efficiency, likely benefiting from its larger cache hierarchy.

Floating-point math delivers the second-largest margin. Intel scores 86540 against AMD's 52971, a 38.8% advantage. This is a substantial gap in a workload that typically reflects raw compute throughput. The Intel chip also wins data encryption by 30.3% (21428 versus 14925), another workload that benefits from the 18 MB shared L3 cache.

The AMD Ryzen AI 7 PRO 450's biggest win is in PassMark integer math, where it scores 86227 versus Intel's 68520, a 25.8% advantage. This is the only test where AMD leads by double digits. Cinebench R23 multi-core gives AMD its second-largest margin at 9.7% (16054 versus 14629.5), confirming the Ryzen's strength in sustained multi-threaded rendering workloads.

Cinebench R15 single-core shows the largest Intel win in the Cinebench suite, with Intel ahead by 23.7% (288.5 versus 220). Interestingly, Cinebench R23 single-core flips in AMD's favor by 2.1% (2010 versus 1969). This inconsistency between the two Cinebench versions suggests the AMD part scales better with the newer test version's workload characteristics.

PassMark multi-thread shows Intel ahead by 11.9% (28119 versus 24779), despite AMD winning both Cinebench multi-core tests. This indicates that PassMark's multi-thread test stresses different aspects of the processors, possibly favoring Intel's 14 physical cores over AMD's 8 cores with 16 threads. Physics simulation also favors Intel by 28.8% (1877 versus 1337), which may reflect the same architectural advantages.

Single-thread performance in PassMark favors Intel by 7.1% (4258 versus 3955). Extended instructions show Intel ahead by 5.2% (21915 versus 20778). Random string sorting gives Intel a 3.9% edge (33654 versus 32344). Data compression is the only PassMark test where AMD wins, at 3.8% (294298 versus 283451).

The Verdict

The recorded data paints a clear picture of two processors with complementary strengths. The AMD Ryzen AI 7 PRO 450 wins 5 benchmarks, including both Cinebench multi-core tests and PassMark integer math. The Intel Core Ultra 5 225H wins 10 benchmarks, taking every floating-point, encryption, physics, and single-thread test except Cinebench R23 single-core.

The average benchmark scores place the AMD part higher overall at 37093, with an 85th percentile ranking among all CPUs. The Intel part averages 31508 with an 82nd percentile ranking. The AMD chip sits near the Intel Core i9-12900T, AMD Ryzen 7 160, Intel Core i7-13700, and AMD Ryzen 7 7735H in overall performance. The Intel chip matches the Intel Core i5-13500, AMD Ryzen 9 5980HX, Intel Core 7 240H, and Intel Core Ultra 3 205.

For rendering workloads measured by Cinebench, the AMD Ryzen AI 7 PRO 450 is the clear choice. Its 9.7% lead in Cinebench R23 multi-core and 2.5% lead in R15 multi-core demonstrate consistent multi-threaded rendering strength. The 25.8% lead in integer math also favors AMD for general integer-heavy processing.

For floating-point, encryption, and prime number workloads, the Intel Core Ultra 5 225H is the better pick. Its 61.8% lead in find prime numbers and 38.8% lead in floating-point math are decisive.
