Head-to-Head Benchmarks

The benchmark data shows a decisive overall win for the Intel Core Ultra 5 225T, which takes 14 of the 15 head-to-head comparisons. The largest single margin is in PassMark find prime numbers, where Intel scores 284 versus 74, a 73.9% advantage. That workload is heavily integer-serial, and the Intel chip's higher clock and single-thread efficiency dominate.

Cinebench R23 multicore shows Intel at 21971 versus AMD at 11534, a 47.5% lead. Cinebench R15 multicore tells a similar story but with a smaller margin: Intel at 2214 versus AMD at 1743, a 21.3% gap. PassMark physics follows the same pattern, with Intel at 2053 against AMD's 1084, a 47.2% lead. PassMark multithread has Intel at 25358 versus AMD's 19215, a 24.2% advantage.

Floating-point performance is heavily one-sided. PassMark floating point math shows Intel at 82751 versus AMD's 39662, a 52.1% margin. Data encryption also favors Intel heavily: 18289 versus 11212, a 38.7% gap. Extended instructions show Intel at 20083 versus AMD's 15721, a 21.7% lead. Random string sorting gives Intel a 15.4% edge (28774 vs 24334), and data compression a 5.3% edge (233998 vs 221581).

Single-core tests are consistently in Intel's favor. Cinebench R23 single-core shows the largest single-thread margin at 41.9% (3101 vs 1802). Cinebench R15 single-core shows 312 versus 276, an 11.5% lead. PassMark single-thread shows 4348 versus 3758, a 13.6% lead. The Intel chip's higher boost clock of 4.90 GHz against 4.80 GHz, combined with its newer 3 nm process and larger L2 cache, explains this pattern.

The AMD Ryzen AI 5 PRO 340's only head-to-head win is in PassMark integer math, where it scores 63233 against Intel's 59543, a 6.2% advantage. This is notable because the same AMD chip loses the find prime numbers test by a wide margin, indicating that the integer math benchmark favors its 12-thread configuration, while the prime number test is more sensitive to single-thread clock speed and memory latency.

The overall score distribution places the Intel part at 30468 average, which is 9.1% higher than the AMD part's 27932. The Intel chip's percentile rank of 82 versus AMD's 80 reinforces that the gap is meaningful across the full CPU database, even though both sit in a similar performance tier.

The Verdict

The data indicates that the Intel Core Ultra 5 225T is the stronger processor in almost every measurable workload. Its 14 wins out of 15 head-to-head benchmarks, combined with an average score 2536 points higher, make it the clear choice for users who prioritize raw performance. The margins are particularly large in multicore rendering, physics, and floating-point workloads, where Intel leads by roughly half.

The AMD Ryzen AI 5 PRO 340 has a narrower set of advantages. It wins integer math by 6.2%, supports ECC memory, supports LPDDR5X memory, and runs at a 28 W TDP compared to Intel's 65 W. For mobile platforms where power efficiency is the primary constraint, the AMD chip is the sensible option. Its 12 threads also give it a flexibility advantage in heavily threaded integer workloads, as the integer math result demonstrates.

The Intel part's 10 cores and larger 20 MB L3 cache deliver consistent wins across rendering, encryption, compression, and single-thread tests. The 82nd percentile ranking versus AMD's 80th percentile confirms that the Intel chip is the higher-performing part in the database's overall distribution. For desktop users with access to PCIe Gen 5 and DDR5, the Intel part is better positioned for sustained workloads.

However, the AMD processor is not without merit in its intended mobile segment. Its 28 W TDP, ECC support, and LPDDR5X compatibility make it attractive for compact systems where thermal and power budgets are tight. The AMD part also holds a 6.2% integer math advantage, which could matter for specific compute tasks that rely on integer throughput rather than floating-point or single-thread speed.

Where Each One Wins

The Intel Core Ultra 5 225T wins in rendering workloads. Cinebench R23 multicore shows a 47.5% lead, and Cinebench R15 multicore shows a 21.3% lead. These results indicate that the Intel part is better suited for CPU-based content creation and 3D rendering tasks.

The Intel part also dominates floating-point and physics workloads. PassMark floating point math shows a 52.1% lead, and PassMark physics shows a 47.2% lead. These are relevant for scientific computing, simulation, and any workload that relies on vector math.

Security and compression tasks favor Intel. PassMark data encryption shows a 38.7% lead, and PassMark data compression shows a 5.3% lead. Extended instructions go to Intel by 21.7%. Single-thread performance is firmly in Intel's camp, with a 41.9% lead in Cinebench R23 single-core and a 13.6% lead in PassMark single-thread. The Intel part's higher boost clock and larger L2 cache support these results.

The AMD Ryzen AI 5 PRO 340 wins only in PassMark integer math, with a 6.2% margin. That makes it the better option for integer-heavy compute tasks that can use its 12 threads. The AMD part also carries platform advantages that are not captured in raw benchmark scores: ECC memory support, LPDDR5X memory compatibility, a 28 W TDP, and a mobile form factor. These traits make it the appropriate choice for power-limited mobile systems where data integrity features and memory flexibility matter more than peak throughput.

For desktop users who need maximum performance across rendering, encryption, and single-thread workloads, the Intel Core Ultra 5 225T is the clear winner based on the recorded data. For mobile users who need ECC support, lower power consumption, and competitive integer throughput, the AMD Ryzen AI 5 PRO 340 delivers those specific advantages.
