AMD Ryzen AI 7 445 vs Intel Core Ultra 5 225H Comparison

Head-to-Head Benchmarks

The benchmark database records a decisive sweep for the Intel Core Ultra 5 225H across every shared test. The AMD Ryzen AI 7 445 wins zero head-to-head comparisons, while the Intel part claims all 15 recorded matchups. This is not a close contest by any metric; the deltas range from a modest 8.3% single-core gap to a dominant 74.5% blowout in prime number computation.

Starting with the most widely cited rendering workloads, the Intel Core Ultra 5 225H delivers a Cinebench R23 multi-core score of 14629.5 against the AMD Ryzen AI 7 445's 10590, a 27.6% advantage. The single-core R23 result narrows the gap: Intel scores 1969 versus AMD's 1806, an 8.3% lead. In the older Cinebench R15 suite, the same pattern holds. The Intel chip posts 2397.5 multi-core and 288.5 single-core, while AMD manages 1723 and 254 respectively, translating to 28.1% and 12% deficits for the Ryzen part.

The PassMark arithmetic suite reveals where the Intel processor's larger core count and higher boost clock matter most. In floating point math, Intel scores 86540 versus AMD's 39362, a 54.5% margin. Prime number finding shows the starkest separation: Intel hits 220 while AMD records only 56, a 74.5% difference. Integer math is comparatively closer, with Intel at 68520 against AMD's 58332, a 14.9% edge. Extended instructions follow with Intel at 21915 and AMD at 15826, a 27.8% gap.

Data-centric workloads follow the same trajectory. PassMark data compression shows Intel at 283451 versus AMD's 215812, a 23.9% win. Data encryption splits more dramatically: Intel reaches 21428, AMD just 10519, a 50.9% difference. Random string sorting gives Intel 33654 against AMD's 23488, a 30.2% margin. Multithreaded throughput in PassMark shows Intel at 28119 and AMD at 18115, a 35.6% gap. Physics simulation scores 1877 for Intel and 976 for AMD, a 48% lead. Single-thread PassMark results put Intel at 4258 and AMD at 3591, a 15.7% advantage.

The Intel Core Ultra 5 225H also holds the overall database percentile position: 82nd percentile versus the AMD Ryzen AI 7 445's 79th. The average benchmark score reinforces this, with Intel at 31508 and AMD at 26936. Nearest rival data places Intel alongside the Intel Core i5-13500 and AMD Ryzen 9 5980HX, both at a 0.0% delta, while AMD's closest matches include the Intel Core i7-1370P and AMD Ryzen 5 7545U with sub-1% differences.

The Verdict

The recorded data points to one unambiguous conclusion: the Intel Core Ultra 5 225H outperforms the AMD Ryzen AI 7 445 in every benchmark the database tracks. The Intel chip's 14 cores, 4.90 GHz boost clock, and 18 MB shared L3 cache produce consistently higher scores across rendering, arithmetic, encryption, compression, and physics workloads. The AMD part, with 6 cores, a 4.60 GHz boost, and 4 MB L3, trails by margins that range from moderate to massive.

For users prioritizing multi-threaded productivity, the Intel Core Ultra 5 225H is the clear selection. Its Cinebench R23 multi-core score of 14629.5 exceeds the AMD part's 10590 by a substantial margin, and PassMark multithread results show a 35.6% gap. Single-core performance also favors Intel, though the 8.3% R23 single-core delta is the narrowest margin in the entire comparison.

The AMD Ryzen AI 7 445 does hold advantages in certain specification areas, but those do not translate into benchmark wins. It supports ECC memory, which the Intel part does not, and it uses a smaller 4 nm process node versus Intel's 3 nm. Its integrated Radeon 840M graphics and AMD Socket FP8 may suit specific platform requirements, but the performance data shows no scenario where the AMD chip wins a recorded test.

The database percentile rankings confirm the hierarchy: Intel sits at the 82nd percentile of all CPUs, AMD at the 79th. The average benchmark scores, 31508 versus 26936, quantify the overall performance difference at roughly 17%. For any workload measured in the database, the Intel Core Ultra 5 225H is the faster processor.

Specification Differences

The two processors diverge significantly in core configuration. The Intel Core Ultra 5 225H packs 14 cores and 14 threads, while the AMD Ryzen AI 7 445 offers 6 cores and 12 threads. This core count disparity directly explains the multi-threaded benchmark gaps.

Clock speeds favor Intel on the boost end. The Intel part boosts to 4.90 GHz, while the AMD chip reaches 4.60 GHz. Base clocks run in the opposite direction: AMD starts at 2.00 GHz, Intel at 1.70 GHz. Both carry a 28 W TDP.

Cache hierarchies differ markedly. Intel provides 192 KB of L1 per core, 3 MB of L2 per core, and 18 MB of shared L3. AMD provides 80 KB of L1 per core, 1 MB of L2 per core, and 4 MB of L3. The L3 difference is particularly consequential for workloads with large working sets.

Memory bandwidth favors Intel at 102.4 GB/s versus AMD's 89.6 GB/s. Both support DDR5 and LPDDR5X over a dual-channel bus. ECC memory support exists only on the AMD side.

PCIe capabilities split by generation. Intel offers Gen 5 with 8 CPU-only lanes, while AMD provides Gen 4 with 14 CPU-only lanes. The newer Gen 5 standard on Intel provides higher per-lane bandwidth, though AMD has more lanes.

Socket and packaging differ completely. Intel uses BGA 2049, AMD uses Socket FP8. Part numbers are SRQAM for Intel and 100-000001935 for AMD. Neither processor has an unlocked multiplier.

Architecture Differences

The Intel Core Ultra 5 225H uses Arrow Lake architecture, specifically the Arrow Lake-H variant within the Ultra 5 generation. It is built on a 3 nm process at TSMC. The AMD Ryzen AI 7 445 uses Zen 5 architecture under the Gorgon Point codename, belonging to the Ryzen AI 400 generation that mixes Zen 5 and Zen 5c cores. It is fabricated on a 4 nm node, also at TSMC.

The core layout explains the performance profile. Intel's 14 cores likely include a mix of performance and efficiency cores typical of Arrow Lake, though the database does not specify the exact composition. AMD's 6 cores in the Ryzen AI 7 445 represent a lower core count designed for efficiency, with a boost clock 0.30 GHz lower than Intel's. The L3 cache difference, 18 MB versus 4 MB, reflects a fundamentally different cache hierarchy design. Intel's larger shared L3 benefits multi-threaded workloads that reuse data, while AMD's smaller L3 may reduce die area and power.

Integrated graphics differ as well. Intel pairs the CPU with Arc Graphics 130T, while AMD uses Radeon 840M. The database does not include iGPU benchmark comparisons, so relative graphics performance is not quantified here.

Release timing places Intel earlier: 2025-01-12 versus AMD's 2026-01-04. Both are listed as active production parts for the mobile market segment.

Where Each One Wins

The Intel Core Ultra 5 225H wins every benchmark category recorded in the database. Its largest margins come in prime number finding (74.5%), floating point math (54.5%), and data encryption (50.9%). These are compute-intensive, multi-threaded workloads where the 14-core configuration and higher boost clock dominate.

For rendering and content creation, Intel leads with a 27.6% Cinebench R23 multi-core advantage and a 28.1% R15 multi-core edge. The 8.3% R23 single-core lead shows Intel also wins lightly threaded tasks, though by a smaller margin. PassMark single-thread results confirm this with a 15.7% gap.

The AMD Ryzen AI 7 445's recorded advantages are purely architectural rather than performance-based. It supports ECC memory, which can matter for data integrity in specific professional contexts. Its 4 nm process node is one generation newer than Intel's 3 nm in terms of process name, though both come from TSMC. The AMD chip also offers more PCIe lanes (14 versus 8), which could benefit systems requiring additional Gen 4 connectivity.

The benchmark data shows no workload where the AMD processor wins. The closest contest is Cinebench R23 single-core, where Intel leads by only 8.3%. Users requiring maximum CPU throughput across rendering, encryption, compression, physics, or arithmetic should select the Intel Core Ultra 5 225H. Users with platform constraints favoring AMD Socket FP8, ECC memory support, or Radeon integrated graphics may still consider the Ryzen AI 7 445, but they must accept a substantial performance deficit in every measured test.
