AMD Ryzen AI 7 450 vs Intel Core Ultra 5 225 Comparison

The Verdict

The benchmark data separates these two processors into distinct roles. The AMD Ryzen AI 7 450 is a mobile chip built for efficiency and specific integer-heavy tasks, while the Intel Core Ultra 5 225 is a desktop part that dominates most compute workloads. The Intel Core Ultra 5 225 wins 12 of the 15 head-to-head tests, while the AMD Ryzen AI 7 450 takes only 3. The overall average benchmark score favors the AMD chip at 39485 versus 36938 for Intel, but that figure is pulled up by a few exceptional AMD results in specific PassMark tests.

The Intel Core Ultra 5 225 should be the pick for users prioritizing raw single-thread performance, floating-point math, encryption, physics simulation, and prime number calculation. Its Cinebench R23 single-core score of 3655 is 44.2% ahead of the AMD chip's 2038. The AMD Ryzen AI 7 450 is the better choice for integer math workloads, data compression, and the older Cinebench R15 multicore test. The data shows a clear split: Intel for general productivity and heavy compute, AMD for specialized integer tasks and mobile deployment.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI 7 450 uses the Zen 5 architecture with the codename Gorgon Point, built on a 4 nm TSMC process. It is a mobile processor with 8 cores and 16 threads, which means simultaneous multithreading is enabled. The Intel Core Ultra 5 225 uses the Arrow Lake architecture with the codename Arrow Lake-S, built on a 3 nm TSMC process. It is a desktop processor with 10 cores and 10 threads, so it lacks simultaneous multithreading. The Intel chip has more physical cores but the AMD chip has more threads.

The process node difference is small but real: 4 nm for AMD versus 3 nm for Intel. The Intel die is larger at 243 mm² with 17,800 million transistors, while the AMD die measures 195 mm². Cache structures differ significantly. The AMD chip allocates 80 KB of L1 per core and 1 MB of L2 per core, with 8 MB of L3. The Intel chip uses 192 KB of L1 per core and 3 MB of L2 per core, with 20 MB of shared L3. That larger shared L3 cache gives Intel an advantage in workloads that reuse data across cores.

Memory support also diverges. The AMD Ryzen AI 7 450 supports DDR5 and LPDDR5X with dual-channel memory and a bandwidth of 89.6 GB/s. It also supports ECC memory. The Intel Core Ultra 5 225 supports only DDR5, also dual-channel, but with higher bandwidth at 102.4 GB/s. ECC memory is not supported on the Intel chip. PCIe capabilities favor Intel: Gen 5 with 20 lanes versus Gen 4 with 16 lanes on the AMD part.

The integrated graphics differ as well. AMD uses the Radeon 860M, while Intel uses Arc Xe-LPG Graphics 16EU. Both are active production parts, and neither has an unlocked multiplier. The Intel chip has a launch MSRP of $246.

Where Each One Wins

The Intel Core Ultra 5 225 wins in almost every category that matters for general desktop use. Single-thread performance is far ahead. Cinebench R23 single-core shows a 44.2% lead, and Cinebench R15 single-core shows a 41.6% lead. PassMark single-thread results confirm the pattern with a 11.6% advantage. This translates to snappier application launches and better performance in lightly threaded software.

In multi-threaded workloads, the Intel chip also leads in most tests. Cinebench R23 multicore shows a 29.3% lead with 25891 versus 18316. PassMark multithread shows a 13.5% lead with 30459 versus 26350. The Intel chip wins PassMark physics by 32.6%, floating-point math by 40.8%, data encryption by 27.1%, and extended instructions by 17.5%. The most dramatic Intel win is in prime number finding, where it scores 358 versus 89, a 75.1% advantage.

The AMD Ryzen AI 7 450 wins in three specific areas. It leads PassMark integer math by 35.5% with 88531 versus 65345. It wins PassMark data compression by 4.3% with 315906 versus 302811. It also wins Cinebench R15 multicore by 4% with 2713 versus 2609. The R15 multicore result is notable because Intel wins the R23 multicore test by a wide margin, suggesting the AMD chip performs relatively better in legacy workloads or tasks that scale differently with thread counts.

The AMD chip also has a lower TDP of 28 watts versus 65 watts for Intel. That efficiency advantage is inherent to its mobile design and makes it suitable for thin laptops, while the Intel chip targets desktop systems with more thermal headroom.

Head-to-Head Benchmarks

The largest Intel victory is in PassMark find prime numbers, where it scores 358 against AMD's 89, a 75.1% margin. This is an extreme outlier and indicates a fundamental advantage in integer-heavy prime calculation algorithms. The next biggest Intel wins are Cinebench R23 single-core with a 44.2% lead, Cinebench R15 single-core with a 41.6% lead, and PassMark floating-point math with a 40.8% lead. The floating-point result is particularly important for scientific computing and 3D rendering, where Intel's 92038 score dwarfs AMD's 54447.

The Intel chip also wins PassMark physics by 32.6% with 2342 versus 1578. This test correlates with gaming physics simulation and particle effects. Data encryption shows a 27.1% Intel lead with 22285 versus 16247, which matters for disk encryption and secure communications. Extended instructions give Intel a 17.5% advantage with 27162 versus 22400, indicating better AVX and SIMD throughput. PassMark multithread shows a 13.5% Intel lead, and single-thread shows a 11.6% lead. Even random string sorting, a narrow win, goes to Intel by 2.6% with 36590 versus 35648.

The AMD victories are narrower and more specialized. PassMark integer math is the standout AMD win: 88531 versus 65345, a 35.5% advantage. This is a massive margin and shows the Zen 5 integer execution units are highly efficient. Data compression gives AMD a 4.3% lead with 315906 versus 302811. Cinebench R15 multicore is the smallest AMD win at 4%, with 2713 versus 2609.

The overall pattern suggests the Intel Core Ultra 5 225 is the stronger all-around processor, but the AMD Ryzen AI 7 450 has a distinct niche in integer math and compression workloads. The Cinebench R15 multicore result breaks the trend of Intel winning all multicore tests, so the AMD chip may be better suited for older software that was optimized for lower thread counts or different scheduling behavior.

Specification Differences

The two processors differ in nearly every specification field. The AMD Ryzen AI 7 450 is a mobile processor using Zen 5 architecture on a 4 nm TSMC process with the codename Gorgon Point.
