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

Where Each One Wins

The recorded benchmark data splits these two processors into clearly different roles. The Intel Core Ultra 5 225T dominates the majority of workloads, taking 13 of 15 head-to-head comparisons, while the AMD Ryzen AI 7 345 claims only two victories. That lopsided scoreboard, however, hides a meaningful division of labor.

The Intel part wins every single-threaded and multi-threaded Cinebench test, plus most PassMark workloads. Its largest margins come in prime number finding (358.1% ahead), floating point math (94.2% ahead), and Cinebench R23 multi-core (91.7% ahead). These are compute-heavy tasks that reward raw execution throughput, and the data shows the Intel chip has substantially more of it. The 225T also leads in data encryption by 54.8%, extended instructions by 18.1%, physics by 88.5%, and random string sorting by 13.1%.

The AMD Ryzen AI 7 345 wins only in integer math (6.2% ahead) and data compression (1.5% ahead). These are narrow margins, suggesting the AMD part has a specific strength in integer-heavy, memory-latency-sensitive work rather than a general performance advantage. Its data compression score of 237,484 edges out the Intel score of 233,998, and its integer math score of 63,475 beats 59,543. Neither margin is large enough to call a rout, but they are consistent wins in that category.

Looking at the overall averages, the Intel part scores 30,468 versus 29,461 for AMD, a difference of about 3.4%. Both sit in the same percentile neighborhood, with Intel at the 82nd percentile of all CPUs and AMD at the 81st. The nearest rival lists reinforce this: the Intel chip trades blows with mobile H-series parts like the Core i5-13600H and Ryzen 5 7640HS, while the AMD chip lands near desktop parts like the Ryzen 7 3800X and EPYC 9654. The data suggests the Intel chip is the stronger all-round performer, while the AMD chip is optimized for a narrower set of tasks.

The Verdict

For users who need maximum compute throughput, the Intel Core Ultra 5 225T is the clear choice from this data. Its multi-core Cinebench R23 score of 21,971 versus 11,461 for the AMD part is a near-doubling of performance, and its single-core R23 score of 3,101 versus 1,818 is a 70.6% advantage. Anyone running rendering, scientific simulations, or heavy number-crunching should look at the Intel part first.

The AMD Ryzen AI 7 345 is the pick only for workloads that specifically favor its integer and compression strengths. The 6.2% lead in integer math and 1.5% lead in data compression are real but modest. For general productivity, database operations, or archival tasks that involve compression, the AMD chip holds its own. Its mobile segment designation and lower 28 W TDP versus 65 W for Intel also suggest it belongs in thinner, cooler-running systems, though the benchmark data itself does not directly measure power consumption.

The percentile rankings tell a similar story: both chips sit near the 81st to 82nd percentile of all CPUs, meaning they are both competent mid-range parts. The Intel chip's average score of 30,468 puts it 0.2% ahead of the Core i9-11980HK and 0.3% ahead of the Ryzen 5 7640HS. The AMD chip's 29,461 average sits 0.0% relative to the Ryzen 7 3800X and 0.2% ahead of the EPYC 9654. These are comparable performance tiers, but the Intel part simply wins more tests and wins them by larger margins.

Head-to-Head Benchmarks

The biggest single win for the Intel Core Ultra 5 225T is in PassMark's find prime numbers test, where it scores 284 versus 62 for the AMD part, a 358.1% advantage. This is an extreme outlier and suggests the Intel architecture handles this particular workload far better, likely due to its higher boost clock of 4.90 GHz versus 4.60 GHz and larger per-core cache.

Floating point math shows a 94.2% lead for Intel (82,751 versus 42,621). This is a workload that scales with SIMD throughput and cache bandwidth, and the Intel part's 20 MB shared L3 cache versus 4 MB for AMD explains part of the gap. The physics test follows a similar pattern, with Intel ahead 88.5% (2,053 versus 1,089). Cinebench R23 multi-core shows a 91.7% lead (21,971 versus 11,461), and Cinebench R23 single-core shows a 70.6% lead (3,101 versus 1,818). Even the older Cinebench R15 tests show Intel ahead by 29.3% multi-core and 15.1% single-core.

Data encryption favors Intel by 54.8% (18,289 versus 11,814). Extended instructions favor Intel by 18.1% (20,083 versus 17,003). Random string sorting favors Intel by 13.1% (28,774 versus 25,435). PassMark single-thread favors Intel by 12.2% (4,348 versus 3,875). PassMark multi-thread favors Intel by 27.3% (25,358 versus 19,927).

The AMD wins are smaller but consistent. Integer math shows 63,475 versus 59,543, a 6.2% edge. Data compression shows 237,484 versus 233,998, a 1.5% edge. These are the only two tests where the AMD part comes out ahead, and neither margin approaches double digits.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Core Ultra 5 225T is built on Arrow Lake architecture using a 3 nm process from TSMC, with 17,800 million transistors on a 243 mm² die. It is a desktop part on Intel Socket 1851. The AMD Ryzen AI 7 345 uses Krackan Point architecture on a 4 nm TSMC process, with the Ryzen AI 300 generation combining Zen 5 and Zen 5c cores. It is a mobile part on AMD Socket FP8.

Intel's Arrow Lake-S design uses a hybrid core approach, though the database does not specify the exact core composition. The AMD part explicitly mixes Zen 5 and Zen 5c cores, which typically means a combination of full-performance and compact efficiency cores. The thread counts reflect this: Intel has 10 cores and 10 threads, while AMD has 6 cores and 12 threads, using simultaneous multithreading to extract more thread-level parallelism from fewer physical cores.

Cache hierarchies differ sharply. Intel allocates 192 KB L1 and 3 MB L2 per core, with 20 MB shared L3. AMD allocates 80 KB L1 and 1 MB L2 per core, with 4 MB L3. The Intel L3 cache is five times larger, which likely contributes to its large leads in floating point math, physics, and prime number tests.

Integrated graphics also differ. The Intel part uses Arc Xe-LPG Graphics with 16 execution units. The AMD part uses Radeon 840M. The database does not include graphics benchmarks, so no performance comparison is possible from this data.

Specification Differences

The two parts differ on nearly every specification field. The Intel Core Ultra 5 225T has 10 cores and 10 threads; the AMD Ryzen AI 7 345 has 6 cores and 12 threads. Intel's base clock is 2.50 GHz versus 2.00 GHz for AMD. Intel's boost clock is 4.90 GHz versus 4.60 GHz for AMD. Intel's TDP is 65 W versus 28 W for AMD.

Memory support differs. Intel supports DDR5 only, while AMD supports both DDR5 and LPDDR5X. Both use dual-channel memory buses. Intel has a memory bandwidth of 102.4 GB/s, while AMD has 89.6 GB/s. Neither supports ECC memory.

PCIe connectivity differs. Intel provides Gen 5 with 20 lanes from the CPU. AMD provides Gen 4 with 14 lanes from the CPU. This gives Intel a generation advantage and more lanes for expansion devices.

The sockets are incompatible: Intel uses Socket 1851, AMD uses Socket FP8. Process nodes differ, with Intel at 3 nm and AMD at 4 nm, both from TSMC. Intel's die carries 17,800 million transistors on 243 mm², while the AMD die size and transistor count are not recorded in the database.

Release dates differ by about two weeks, with Intel launching on 2024-12-31 and AMD on 2025-01-14. Both are active production parts, neither has an unlocked multiplier, and neither has a recorded launch MSRP in the database. The AMD part has a part number of 100-000002122, while the Intel part number is listed as unknown.
