AMD Ryzen AI 5 435 vs Intel Core Ultra 5 225H Comparison

The Verdict

The recorded benchmark data shows a one-sided comparison. The Intel Core Ultra 5 225H wins every single head-to-head test in the database, taking all 15 recorded matchups. The AMD Ryzen AI 5 435 records zero wins. For workloads measured across Cinebench and PassMark suites, the Intel part is consistently faster, with the largest margin reaching 73.6% in prime number finding.

The AMD Ryzen AI 5 435 still holds a place for systems where its specific feature set matters. It supports ECC memory, which the Intel part does not. Its socket, AMD Socket FP8, differs from Intel BGA 2049, so platform choice dictates which processor fits. The AMD chip also uses a 4 nm process node versus Intel's 3 nm node, but that manufacturing difference does not translate into benchmark advantages in this data.

The data suggests the Intel Core Ultra 5 225H is the stronger choice for raw performance across the tested applications. The AMD Ryzen AI 5 435 remains relevant only when ECC memory support or the AMD platform is a requirement, since its performance profile trails in every recorded test.

Architecture Differences

The two processors come from different design generations. The AMD Ryzen AI 5 435 uses the Zen 5 architecture under the Gorgon Point codename, belonging to the Ryzen AI 400 generation that combines Zen 5 and Zen 5c cores. The Intel Core Ultra 5 225H uses the Arrow Lake architecture under the Arrow Lake-H codename, part of the Core Ultra Series 2 family.

Core counts diverge substantially. The AMD part has 6 cores and 12 threads, while the Intel part has 14 cores and 14 threads. The Intel chip does not use simultaneous multithreading, so thread count equals core count. The AMD chip gains its 12 threads from 6 cores with two threads per core.

Cache layouts differ in structure and size. The AMD processor provides 80 KB of L1 cache per core, 1 MB of L2 per core, and 4 MB of L3 cache. The Intel processor provides 192 KB of L1 per core, 3 MB of L2 per core, and 18 MB of shared L3 cache. These figures show Intel's larger cache allocation at every level.

Process technology also differs. AMD uses a 4 nm node from TSMC. Intel uses a 3 nm node, also from TSMC. Both chips are mobile-market parts with active production status, and both are locked with no unlocked multiplier.

Memory support is similar in type: both support DDR5 and LPDDR5X over dual-channel buses. The peak memory bandwidth differs, with AMD rated at 89.6 GB/s and Intel at 102.4 GB/s. ECC memory support is present on the AMD part but absent on the Intel part. PCIe connectivity differs as well: AMD offers Gen 4 with 14 CPU lanes, while Intel offers Gen 5 with 8 CPU lanes.

Integrated graphics also differ. The AMD chip carries a Radeon 840M. The Intel chip carries Arc Graphics 130T. The database does not include graphics benchmarks for either, so no performance comparison can be made from this data.

Where Each One Wins

The Intel Core Ultra 5 225H wins in every category covered by the shared benchmark set. In Cinebench R15, the Intel part scores 2397.5 in multi-core against AMD's 1686, a 29.7% lead. In single-core R15, Intel leads by 9.9% with 288.5 versus 260. In Cinebench R23, Intel leads multi-core by 22.5% (14629.5 versus 11333) and single-core by 7.8% (1969 versus 1816).

PassMark results follow the same pattern. The largest Intel advantage appears in find prime numbers, where Intel scores 220 against AMD's 58, a 73.6% gap. Floating point math shows a 53.1% Intel lead (86540 versus 40627). Data encryption shows a 48.2% lead (21428 versus 11110). Physics tests show a 42.7% lead (1877 versus 1075). Multithread tests show a 32.4% lead (28119 versus 19000).

The Intel part also wins in more moderate margins. Integer math shows a 10.9% lead (68520 versus 61026). Single-thread PassMark shows a 12.3% lead (4258 versus 3734). Random string sorting shows a 26% lead (33654 versus 24891). Extended instructions show a 26.1% lead (21915 versus 16197). Data compression shows a 20.5% lead (283451 versus 225374).

The AMD Ryzen AI 5 435 does not win any recorded test. Its only distinguishing advantages in the data are architectural features: ECC memory support, a different socket, and a lower process node number. Performance-wise, the database records no area where AMD comes out ahead.
