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

Head-to-Head Benchmarks

The recorded benchmark data shows a decisive overall advantage for the Intel Core Ultra 5 225T. Across the shared test suite, the Intel part wins 14 of the 15 head-to-head comparisons, while the AMD Ryzen AI 5 435 takes a single victory. The magnitude of the Intel wins varies widely, from narrow margins in compression workloads to massive gaps in prime number calculation and floating point math.

In Cinebench R23 multicore, the Intel Core Ultra 5 225T scores 21971 against 11333 for the AMD Ryzen AI 5 435. That is a 48.4% lead for Intel, the largest delta in the entire comparison set. The single-core R23 result follows the same pattern: Intel scores 3101, AMD scores 1816, a 41.4% gap. These two results alone indicate that the Intel part holds a substantial advantage in both lightly threaded and heavily threaded rendering tasks. The older Cinebench R15 tests confirm the trend, with Intel ahead by 23.8% in multicore (2214 vs 1686) and by 16.7% in single-core (312 vs 260).

PassMark workloads show a more mixed picture. In data compression, the Intel part leads by a modest 3.7% (233998 vs 225374). That is the closest Intel victory in the entire set. In data encryption, Intel leads by 39.3% (18289 vs 11110). Extended instructions see Intel ahead by 19.3% (20083 vs 16197). Floating point math shows a huge Intel advantage: 82751 vs 40627, a 50.9% gap. Physics simulation also favors Intel heavily, with 2053 vs 1075, a 47.6% margin. Random string sorting goes to Intel by 13.5% (28774 vs 24891).

The single AMD win comes in integer math. The Ryzen AI 5 435 scores 61026 against 59543 for the Intel part, a 2.5% edge. This is the only category where the AMD chip demonstrates a measurable advantage, and the margin is small relative to the Intel leads seen elsewhere. In the multithread PassMark test, Intel leads by 25.1% (25358 vs 19000). Single-thread PassMark shows Intel ahead by 14.1% (4348 vs 3734). The find prime numbers test produces the largest relative gap of all: Intel scores 284, AMD scores 58, a 79.6% difference. This category heavily favors the Intel architecture.

The average benchmark score for the Intel part is 30468, compared to 28128 for the AMD part. The Intel chip sits at the 82nd percentile among all CPUs in the database, while the AMD chip sits at the 80th percentile. The nearest rival data places the Intel part alongside the Intel Core i9-11980HK (delta 0.2%), the AMD Ryzen 5 7640HS (delta 0.3%), and the Intel Core i5-13600H (delta -0.3%). The AMD part sits near the Intel Core i5-13490F (delta -0.2%), the Intel Core i5-14500T (delta 0.2%), and two AMD Ryzen 5 PRO parts (delta 0.3% each). These deltas indicate that both processors are competitive within their immediate peer groups, but the Intel part is positioned at a higher absolute performance tier.

Architecture Differences

The two processors come from fundamentally different design families. The AMD Ryzen AI 5 435 uses the Zen 5 architecture with the codename Gorgon Point, belonging to 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 with the codename Arrow Lake-S, part of the Core Ultra Series 2 generation. It is built on a 3 nm process, also at TSMC. Intel lists 17,800 million transistors and a die size of 243 mm² for this part; AMD does not provide those figures in the database.

Core counts differ substantially. The AMD chip has 6 cores and 12 threads, while the Intel chip has 10 cores and 10 threads. Notably, the Intel part does not use simultaneous multithreading, while the AMD part does. Despite having fewer threads, the Intel chip wins every multithreaded benchmark in the comparison, which indicates that its 10 physical cores deliver more aggregate throughput than AMD's 6 cores with SMT.

Clock speeds also favor Intel. The AMD chip has a base clock of 2.00 GHz and a boost clock of 4.50 GHz. The Intel chip has a base clock of 2.50 GHz and a boost clock of 4.90 GHz. The Intel part runs higher at both idle and peak. Thermal design power differs sharply: AMD lists 28 W, Intel lists 65 W. The Intel part consumes more power, but the benchmark data shows that it converts that power into considerably higher performance across most workloads.

Cache layouts diverge. The AMD chip has 80 KB of L1 per core, 1 MB of L2 per core, and 4 MB of L3 total. The Intel chip has 192 KB of L1 per core, 3 MB of L2 per core, and 20 MB of shared L3. The Intel part has substantially more cache at every level, which likely contributes to its lead in latency-sensitive and data-heavy workloads. The L3 difference is particularly large: 20 MB versus 4 MB.

Memory support differs. Both support dual-channel memory, but AMD lists DDR5 and LPDDR5X, while Intel lists only DDR5. AMD lists memory bandwidth at 89.6 GB/s, Intel at 102.4 GB/s. AMD supports ECC memory; Intel does not. PCIe connectivity also differs: AMD provides Gen 4 with 14 lanes (CPU only), Intel provides Gen 5 with 20 lanes (CPU only). The Intel part offers a newer PCIe generation and more lanes.

Integrated graphics also diverge. The AMD chip uses a Radeon 840M, while the Intel chip uses Arc Xe-LPG Graphics with 16 EUs. The database does not include graphics benchmarks for either part, so no performance comparison can be made from the recorded data. The market segments differ as well: AMD is a mobile part, Intel is a desktop part. Sockets differ accordingly: AMD uses Socket FP8, Intel uses Socket 1851. Both are currently in active production.

The Verdict

The data points to a clear performance hierarchy. The Intel Core Ultra 5 225T wins 14 of 15 head-to-head benchmarks, often by large margins. In Cinebench R23 multicore, it leads by 48.4%. In floating point math, it leads by 50.9%. In find prime numbers, it leads by 79.6%. These are not marginal differences; they represent a full performance tier above the AMD part.

The AMD Ryzen AI 5 435 does have one notable strength: integer math. It beats the Intel part by 2.5% in that specific PassMark test. It also has a lower TDP of 28 W versus 65 W, which suggests it may be more efficient in absolute power draw, although the database does not provide performance-per-watt calculations. The AMD part also supports ECC memory and LPDDR5X, which the Intel part does not.

For workloads that rely on integer arithmetic, the AMD chip is marginally better. For everything else in the measured suite, the Intel chip is significantly better. The Intel part also has a higher average benchmark score (30468 vs 28128) and a higher percentile ranking (82 vs 80). The Intel chip sits in a peer group that includes the Core i9-11980HK and Core i5-13600H, while the AMD chip sits with the Core i5-13490F and Core i5-14500T. That peer placement confirms that the Intel part belongs to a higher performance bracket.

Where Each One Wins

The Intel Core Ultra 5 225T dominates the majority of recorded workloads. It wins in all three Cinebench tests (R15 multicore, R15 single-core, R23 multicore, R23 single-core, and the additional R20 tests not shared by AMD but recorded for Intel). It also wins in data compression, data encryption, extended instructions, find prime numbers, floating point math, multithread, physics, random string sorting, and single-thread tests. The margins in rendering (R23 multicore at 48.4%), physics (47.6%), and floating point math (50.9%) are particularly pronounced. Users running CPU-intensive compute tasks such as 3D rendering, physics simulation, or heavy floating point calculations would clearly prefer this part based on the data.

The AMD Ryzen AI 5 435 wins only in PassMark integer math. The margin is 2.5%, which is small but consistent. The AMD part also has a much lower TDP (28 W versus 65 W), which may matter for systems with strict power budgets, though the database does not measure actual power draw. The AMD chip supports ECC memory, which is relevant for error-sensitive workloads, and it supports LPDDR5X memory, which is not available on the Intel part. The AMD chip is a mobile part, so it is designed for notebooks and compact systems, while the Intel part is a desktop part.

For single-threaded performance, the Intel part leads by 14.1% in PassMark single-thread and by 41.4% in Cinebench R23 single-core. For multithreaded performance, the Intel part leads by 25.1% in PassMark multithread and by 48.4% in Cinebench R23 multicore. There is no benchmark category in the shared suite where the AMD part comes close to Intel outside of integer math and data compression, where Intel still leads by 3.7%.
