Architecture Differences

The two processors come from different design philosophies and physical packages. The AMD Ryzen AI 7 445 uses the Zen 5 architecture under the Gorgon Point codename, part of the Ryzen AI 400 generation that mixes Zen 5 and Zen 5c cores. It is built on a 4 nm process at TSMC. The Intel Core Ultra 5 225T uses the Arrow Lake architecture (Arrow Lake-S codename), part of the Core Ultra Series 2, built on a 3 nm process, also at TSMC. Intel lists 17,800 million transistors on a 243 mm² die, while the AMD part has no transistor or die size data recorded.

Core topology differs substantially. The AMD chip has 6 cores and 12 threads, indicating simultaneous multithreading. The Intel chip has 10 cores and 10 threads, with no multithreading, meaning each core is a physical thread. Cache layouts are distinct: the AMD part carries 80 KB of L1 per core, 1 MB of L2 per core, and 4 MB of L3. The Intel part carries 192 KB of L1 per core, 3 MB of L2 per core, and a much larger 20 MB of shared L3 cache. The larger Intel cache pool likely contributes to its higher scores in memory-sensitive workloads such as data compression and encryption.

The integrated graphics differ as well. AMD pairs the CPU with a Radeon 840M, while Intel uses Arc Xe-LPG Graphics with 16 execution units. The AMD part supports ECC memory; the Intel part does not. The AMD chip supports both DDR5 and LPDDR5X memory, whereas the Intel part supports DDR5 only. PCIe connectivity also diverges: AMD offers Gen 4 with 14 CPU lanes, while Intel offers Gen 5 with 20 CPU lanes. The Intel chip has a higher base clock (2.50 GHz vs 2.00 GHz) and a higher boost clock (4.90 GHz vs 4.60 GHz).

Head-to-Head Benchmarks

The Intel Core Ultra 5 225T wins every recorded comparison, but the margins vary greatly by workload type. The largest Intel advantage appears in prime number finding, where it scores 284 versus 56, a 80.3% delta. This test is highly sensitive to core count and integer execution efficiency, and the Intel part's 10 physical cores and higher clocks dominate. Floating point math also shows a massive gap: Intel scores 82,751 versus 39,362, a 52.4% delta. Physics simulation follows a similar pattern, with Intel at 2,053 versus 976, a 52.5% delta.

Multi-core rendering is another strong area for Intel. Cinebench R23 multi-core shows Intel at 21,971 versus 10,590, a 51.8% delta. Cinebench R15 multi-core is closer but still Intel-favored at 2,214 versus 1,723, a 22.2% delta. PassMark multi-thread shows Intel ahead at 25,358 versus 18,115, a 28.6% delta. Encryption also favors Intel heavily: 18,289 versus 10,519, a 42.5% delta.

The narrowest margins appear in integer-heavy and single-thread tests. PassMark integer math is nearly a tie, with Intel at 59,543 versus 58,332, a 2% delta. Data compression is also close, with Intel at 233,998 versus 215,812, a 7.8% delta. Single-core tests favor Intel but not by the same magnitude as multi-core tests. Cinebench R23 single-core shows a 41.8% delta (3,101 vs 1,806), while Cinebench R15 single-core shows 312 versus 254, an 18.6% delta. PassMark single-thread shows 4,348 versus 3,591, a 17.4% delta. Extended instructions favor Intel by 21.2% (20,083 vs 15,826), and random string sorting favors Intel by 18.4% (28,774 vs 23,488).

Where Each One Wins

The recorded data gives the Intel Core Ultra 5 225T a clean sweep, so the use-case split follows the size of the Intel advantage rather than any AMD victory. The Intel chip is strongest relative to the AMD part in prime number finding (80.3% ahead), physics simulation (52.5%), floating point math (52.4%), and Cinebench R23 multi-core (51.8%). These results point to workloads that scale with physical cores, large shared L3 cache, and higher boost clocks: scientific computing, rendering, and physics-based simulations.

The Intel chip also holds a decisive edge in data encryption (42.5% ahead), which benefits from its higher clock speeds and newer architecture. Extended instructions favor Intel by 21.2%, indicating an advantage in SIMD-oriented workloads. In contrast, the closest competition comes in integer math (2% delta) and data compression (7.8% delta). Those two tests are the only places where the AMD Ryzen AI 7 445 approaches parity, suggesting that its Zen 5 cores are efficient at integer operations relative to the Intel part's wider core count advantage.

The AMD Ryzen AI 7 445 holds no benchmark wins, but its profile is defined by mobility. It is a mobile processor on a 28 W TDP, versus the Intel desktop chip at 65 W. It supports LPDDR5X memory and ECC, which are not present on the Intel part. Its lower power envelope and mobile socket make it suited to compact or battery-powered systems, while the Intel chip is suited to desktop builds where higher power draw and larger cooling are acceptable. The AMD part's Radeon 840M integrated graphics may serve lighter visual tasks, but the database records no graphics benchmarks to compare.

The Verdict

The benchmark data is unambiguous: the Intel Core Ultra 5 225T outperforms the AMD Ryzen AI 7 445 in every recorded test. The average benchmark score confirms the pattern, with Intel at 30,468 versus 26,936, a margin that places it in the 82nd percentile of all CPUs compared to the AMD part's 79th. The Intel chip's 10 physical cores, 20 MB of shared L3 cache, 3 nm process, and higher clocks (4.90 GHz boost) drive its wins across rendering, math, encryption, and single-thread tests. The largest deltas, 80.3% in prime numbers and 52.4% in floating point math, indicate a fundamental throughput advantage that the AMD part cannot offset with its 12 threads or Zen 5 architecture.

For a desktop user prioritizing raw compute, the data points exclusively to the Intel Core Ultra 5 225T. For a mobile or low-power build, the AMD Ryzen AI 7 445 remains the only viable option in this comparison because of its socket, 28 W TDP, and LPDDR5X support, but the performance trade-off is substantial. The database records no scenario where the AMD chip leads, so any selection between these two should be driven by platform requirements, not expected performance.
