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

The database places the AMD Ryzen AI 7 345 and the Intel Core Ultra 5 225H in the same mobile performance tier, but the head-to-head results are one-sided. Intel wins all 15 recorded comparisons, and its average benchmark score of 31508 sits above AMD's 29461. Intel also ranks at the 82nd percentile of all CPUs, one point above AMD's 81st. Both processors are 28 W mobile parts that use TSMC manufacturing and support DDR5 and LPDDR5X memory, but their internal designs lead to very different benchmark outcomes.

Where Each One Wins

Benchmark wins are entirely on the Intel side. The database records 15 head-to-head tests, and the Intel Core Ultra 5 225H wins all 15; the AMD Ryzen AI 7 345 records zero wins. That makes the use-case split one-sided. The Intel part wins in Cinebench R15 and R23, both multicore and singlecore, and in every PassMark workload in the comparison: data compression, data encryption, extended instructions, prime numbers, floating-point math, integer math, multithread, physics, random string sorting, and single-thread. There is no recorded workload category where the AMD part takes the lead.

The overall percentile gap is small, but the direct comparison is not. AMD sits at the 81st percentile of all CPUs, while Intel sits at the 82nd. Looking at nearest rivals, AMD's average score of 29461 is essentially level with the AMD Ryzen 7 3800X at 29447, a delta of 0, and the AMD EPYC 9654 at 29409, a delta of 0.2. Intel's average of 31508 is level with the Intel Core i5-13500 at 31510, a delta of 0, and the AMD Ryzen 9 5980HX at 31495, also a delta of 0. The Intel part's nearest rivals also include the Intel Core 7 240H at 31483 and the Intel Core Ultra 3 205 at 31473, both with a delta of 0.1. In terms of aggregate standing, the two CPUs are close; in terms of direct head-to-head results, Intel dominates every category.

Architecture Differences

Architecture differences explain the benchmark pattern. The AMD part is a Krackan Point chip built on a 4 nm process, using a Ryzen AI 300 generation design with Zen 5 / Zen 5c cores. It has 6 cores and 12 threads. The Intel part is an Arrow Lake-H chip built on a 3 nm process, using the Core Ultra Series 2 generation with 14 cores and 14 threads. The Intel part therefore presents more physical cores, while the AMD part reaches 12 threads from 6 cores. Both parts have the same 28 W TDP, but the core allocation is fundamentally different.

Cache configurations differ sharply. AMD provides 80 KB of L1 per core, 1 MB of L2 per core, and a 4 MB L3 cache. Intel provides 192 KB of L1 per core, 3 MB of L2 per core, and 18 MB of shared L3. The larger L3 cache on the Intel part aligns with its wide leads in data compression, random string sorting, and extended instructions. Memory bandwidth also favors Intel: 102.4 GB/s versus 89.6 GB/s, both over a dual-channel DDR5 and LPDDR5X memory bus. The PCIe interface differs as well, with AMD using Gen 4 and 14 CPU lanes, while Intel uses Gen 5 and 8 CPU lanes.

Integrated graphics differ, with AMD using the Radeon 840M and Intel using the Arc Graphics 130T. Neither part supports ECC memory, and both are listed as active mobile parts. AMD uses Socket FP8, while Intel uses BGA 2049, so the two are not socket-compatible. The release dates are close: AMD is dated 2025-01-14 and Intel is dated 2025-01-12. The part numbers are also different, with AMD listed as 100-000002122 and Intel as SRQAM.

Head-to-Head Benchmarks

The largest Intel win is in PassMark find prime numbers. Intel scores 220 against AMD's 62, a 71.8% advantage. That is the single biggest delta in the comparison. Floating-point math also shows a severe gap: Intel scores 86540 versus 42621, a 50.7% lead. Data encryption follows at 44.9%, with Intel at 21428 and AMD at 11814. Physics is close behind at 42%, with Intel at 1877 and AMD at 1089. These are large, consistent margins in compute-heavy workloads.

Multithreaded rendering favors Intel as well. In Cinebench R15 multicore, Intel scores 2397.5 versus 1712, a 28.6% lead. In Cinebench R23 multicore, Intel scores 14629.5 versus 11461, a 21.7% lead. PassMark multithread shows 28119 versus 19927, a 29.1% lead. PassMark integer math is closer at 7.4%, with Intel at 68520 and AMD at 63475. Data compression is 16.2% in Intel's favor, with 283451 against 237484.

Single-thread performance favors Intel by smaller margins. Cinebench R15 singlecore shows 288.5 versus 271, a 6.1% lead. Cinebench R23 singlecore shows 1969 versus 1818, a 7.7% lead. PassMark single-thread shows 4258 versus 3875, a 9% lead. The smallest lead in the entire comparison is the 6.1% R15 singlecore margin, followed by the 7.4% integer math margin and the 7.7% R23 singlecore margin. Even in the closest tests, Intel still wins.

The remaining results follow the same direction. Extended instructions show 21915 versus 17003, a 22.4% lead. Random string sorting shows 33654 versus 25435, a 24.4% lead. The head-to-head table contains zero AMD wins, so every workload in the database moves the same way. The AMD part's best showings are in single-core tests and integer math, but those are still Intel wins.

The Verdict

The recorded data supports a clear outcome. The Intel Core Ultra 5 225H wins every head-to-head benchmark in the database, holds a higher average benchmark score of 31508 versus 29461, and ranks one percentile point higher at 82 versus 81. The AMD Ryzen AI 7 345 does not win any direct comparison. For workloads represented by Cinebench and PassMark, the Intel part is the one indicated by the data.

The AMD part remains a 6-core, 12-thread Krackan Point processor with a 4 MB L3 cache and Radeon 840M graphics. Those traits do not translate into a benchmark win against the Intel part in any recorded test. The Intel part uses a larger core count, a 3 nm process, 18 MB of shared L3, and higher memory bandwidth, and the benchmark results reflect those differences. A system integrator or user selecting strictly on recorded performance would choose the Intel Core Ultra 5 225H.
