AMD Ryzen AI 7 345 vs Intel Core Ultra 5 225F Comparison

Head-to-Head Benchmarks

The recorded data shows a clean sweep for the Intel Core Ultra 5 225F across all 15 shared benchmark tests. The AMD Ryzen AI 7 345 did not secure a single win in any of the head-to-head comparisons. The largest margins appear in heavily parallel workloads, where the Intel part's higher core count and desktop-oriented power envelope produce substantial gaps.

In Cinebench R23 multi-core, the Intel Core Ultra 5 225F scores 16,467 against the AMD Ryzen AI 7 345's 11,461, a 30.4% advantage. The Cinebench R15 multi-core result shows a larger relative gap: 2,660 versus 1,712, which translates to a 35.6% lead for Intel. Single-core results are much closer. The Intel part wins Cinebench R23 single-core with 1,893 versus 1,818, a 4% difference, and Cinebench R15 single-core with 287 versus 271, a 5.6% gap. These numbers indicate that per-thread performance is broadly similar, while the multi-core delta is driven by additional physical cores and higher sustained power.

PassMark results reinforce the pattern. The largest single delta in the entire dataset is in the find prime numbers test, where Intel scores 352 versus AMD's 62, an 82.4% deficit for the Ryzen part. Floating point math shows a 54% gap (92,554 versus 42,621), and physics simulation shows a 55.2% gap (2,430 versus 1,089). Data encryption is also lopsided at 47.8% (22,648 versus 11,814). Extended instructions follow with a 39.3% delta (28,027 versus 17,003).

Some tests are far closer. Integer math shows only a 4.4% difference (66,417 versus 63,475). Data compression is a 23.6% gap (310,843 versus 237,484). Random string sorting shows a 31.9% delta (37,325 versus 25,435). The multithread PassMark score is 31,004 versus 19,927, a 35.7% difference, while single-thread PassMark is 4,397 versus 3,875, an 11.9% gap.

The average benchmark score from the database places the Intel part at 37,313, which sits in the 85th percentile of all CPUs. The AMD part averages 29,461, placing it in the 81st percentile. The Intel chip's nearest rivals include the Intel Core i9-13900HK (average 37,425, a 0.3% gap) and the AMD Ryzen 7 7735H (37,161, a 0.4% gap). The AMD chip's nearest rivals include the AMD Ryzen 7 3800X (29,447, essentially tied) and the Intel Core i5-13500HX (29,270, a 0.7% gap).

Architecture Differences

The two processors come from different market segments, and that distinction shows in their physical specifications. The AMD Ryzen AI 7 345 is a mobile part on AMD Socket FP8, using the Krackan Point codename from the Ryzen AI 300 generation built on Zen 5 / Zen 5c cores. It packs 6 cores and 12 threads with a base clock of 2.00 GHz and a boost clock of 4.60 GHz. Its thermal design power is 28 watts. The Intel Core Ultra 5 225F is a desktop chip on Intel Socket 1851, using Arrow Lake-S architecture from the Ultra 5 (Arrow Lake) generation. It provides 10 cores and 10 threads with a base clock of 3.30 GHz and a boost clock of 4.90 GHz. Its TDP is 65 watts.

The Intel part lacks simultaneous multithreading, which explains the equal core and thread counts. The AMD part uses simultaneous multithreading to double its 6 cores into 12 threads. This is a fundamental design difference: Intel relies on more physical cores, while AMD relies on threading to handle concurrent workloads.

Process technology differs as well. The AMD chip is built on a 4 nm process at TSMC. The Intel chip uses a 3 nm process, also at TSMC. Intel's die is listed at 243 mm² with 17,800 million transistors; the AMD die size and transistor count are not recorded in the database.

Cache hierarchies are distinct. The AMD Ryzen AI 7 345 has 80 KB of L1 per core, 1 MB of L2 per core, and only 4 MB of shared L3 cache. The Intel Core Ultra 5 225F has 192 KB of L1 per core, 3 MB of L2 per core, and 20 MB of shared L3. The larger L3 allocation on the Intel part is notable for workloads that reuse data sets, though the benchmark data does not isolate cache-sensitive tests.

Memory support also differs. The AMD chip supports DDR5 and LPDDR5X over a dual-channel bus with 89.6 GB/s of bandwidth. The Intel chip supports DDR5 only, also dual-channel, but with a higher 102.4 GB/s of bandwidth. Neither part supports ECC memory.

PCIe connectivity is asymmetric. The AMD part provides Gen 4 with 14 lanes from the CPU. The Intel part provides Gen 5 with 20 lanes from the CPU. The Intel chip has no integrated graphics, while the AMD chip includes the Radeon 840M iGPU. The AMD part is classified as mobile, the Intel part as desktop.

Where Each One Wins

The Intel Core Ultra 5 225F wins every recorded benchmark, so the analysis of "wins" is about the magnitude of its advantage and what that implies for specific use cases. The largest deltas appear in integer-heavy, math-heavy, and simulation-heavy workloads. The find prime numbers test, which is highly dependent on raw integer throughput and cache behavior, shows an 82.4% lead for Intel. Floating point math shows a 54% lead, and physics simulation shows a 55.2% lead. Data encryption, which often scales with core count and memory bandwidth, shows a 47.8% lead. These results suggest the Intel part is disproportionately stronger in compute-bound, non-threaded or lightly-threaded tasks that stress the execution engine.

The AMD Ryzen AI 7 345's closest margins are in single-threaded tests. Cinebench R23 single-core shows only a 4% gap, and Cinebench R15 single-core shows a 5.6% gap. Integer math is nearly tied at 4.4%. This indicates that for single-threaded productivity tasks, the AMD chip is competitive despite its lower boost clock and smaller cache. The AMD part also holds a smaller deficit in data compression (23.6%) compared to its larger losses in math and physics, suggesting that its memory subsystem and thread scheduling handle compression workloads relatively better.

For mobile use, the AMD part's 28-watt TDP and integrated Radeon 840M graphics make it suitable for thin-and-light systems where discrete GPUs are absent. The Intel part, with a 65-watt TDP and no iGPU, requires a discrete graphics card and a desktop platform. The benchmark data does not include graphics tests, so the iGPU comparison is qualitative. The AMD chip's LPDDR5X support also aligns with mobile memory configurations, while the Intel chip's DDR5-only support fits desktop DIMMs.

The Verdict

The data is unambiguous: the Intel Core Ultra 5 225F outperforms the AMD Ryzen AI 7 345 in every measured test. Its average benchmark score is 37,313 versus 29,461, a 26.6% advantage. The Intel part reaches the 85th percentile of all CPUs, while the AMD part sits at the 81st percentile. For any workload represented in this database, the Intel chip delivers higher raw performance.

The AMD Ryzen AI 7 345 is not without merit, but its strengths are contextual. It offers a lower TDP by more than half (28 watts versus 65 watts), which matters for battery-powered systems. It includes integrated graphics, while the Intel part has none. Its single-threaded scores trail by only 4% to 5.6% in Cinebench tests, meaning the gap narrows in lightly threaded scenarios. However, in multi-threaded and math-intensive tasks, the Intel part's 10 physical cores and larger L3 cache produce decisive wins, often exceeding 30% and reaching as high as 82.4%.

Pick the Intel Core Ultra 5 225F if the system is a desktop with a discrete GPU and the priority is maximum throughput in CPU-bound tasks. Pick the AMD Ryzen AI 7 345 if the platform is a mobile device where power draw, integrated graphics, and LPDDR5X memory support are required. The benchmark database does not support any conclusion that the AMD part is faster in any measurable way; it only shows that the AMD part is closer in single-threaded tests and consumes far less power.
