AMD Ryzen AI 7 345 vs Intel Core 9 270H Comparison

The benchmark data is unambiguous: the Intel Core 9 270H dominates the AMD Ryzen AI 7 345 across every single recorded test. The Intel part wins all 15 head-to-head comparisons, with its largest advantages appearing in heavily multithreaded workloads. The AMD Ryzen AI 7 345 does close the gap in single-threaded performance, where the Intel lead shrinks to a marginal 1.7%, but that is the only area where the two are remotely competitive.

The Verdict

The Intel Core 9 270H is the clear performance choice based on the recorded data. Its average benchmark score of 38335 places it in the 86th percentile of all CPUs, while the AMD Ryzen AI 7 345 sits at 29461 and the 81st percentile. The Intel chip delivers a 30.1% higher average score, and it wins every workload category measured, from compression to physics to encryption. The data indicates the Intel Core 9 270H is suited for users who need maximum throughput in CPU-intensive tasks, whether those are rendering workloads, data processing, or encryption-heavy operations.

The AMD Ryzen AI 7 345, by contrast, has no benchmark victories to point to. Its strongest relative performance is in single-threaded tests, where it trails by only 1.7% in PassMark single-thread scoring. The database also shows the AMD part operates at a 28 TDP versus the Intel part's 45 TDP, which suggests a lower power envelope, but the recorded data does not include any efficiency measurements. For a user prioritizing raw performance in a mobile processor, the Intel Core 9 270H is the only defensible pick from these numbers. The AMD part would be chosen primarily for its lower TDP and different platform attributes, not for any measured performance advantage.

Architecture Differences

The two processors come from different design schools. The AMD Ryzen AI 7 345 uses the Krackan Point codename and belongs to the Ryzen AI 300 generation built on Zen 5 and Zen 5c cores. It is fabricated on a 4 nm process at TSMC. The Intel Core 9 270H uses the Raptor Lake architecture, specifically the Raptor Lake-H variant under the Raptor Lake Refresh generation, and is built on a 10 nm process at Intel's own foundry.

Core counts differ substantially. The AMD chip has 6 cores and 12 threads, while the Intel chip has 14 cores and 20 threads. The Intel processor's higher core and thread count is the structural basis for its large multithreaded wins. Cache layouts also diverge: the AMD part has 1 MB of L2 per core and 4 MB of total L3 cache, while the Intel part has 2 MB of L2 per core and a shared 24 MB L3 cache. Both have 80 KB of L1 per core.

Platform features differ as well. The AMD Ryzen AI 7 345 uses AMD Socket FP8, supports DDR5 and LPDDR5X memory in a dual-channel configuration, and has a memory bandwidth of 89.6 GB/s. It provides PCIe Gen 4 with 14 CPU lanes. The Intel Core 9 270H uses Intel BGA 1744, supports DDR4 and DDR5 in dual-channel mode, and provides PCIe Gen 5 with 8 CPU lanes. The AMD part integrates a Radeon 840M GPU, while the Intel part integrates Iris Xe Graphics with 96 execution units. Neither processor supports ECC memory, and neither has an unlocked multiplier.

Head-to-Head Benchmarks

The Intel Core 9 270H wins every recorded comparison, but the margins vary widely by workload. The smallest Intel advantage appears in single-threaded tests. In Cinebench R23 single-core, the Intel chip scores 2040 against 1818 for the AMD chip, a 10.9% lead. In Cinebench R15 single-core, the Intel score is 347 versus 271, a 21.9% lead. The PassMark single-thread result shows the closest contest of all: 3944 for Intel versus 3875 for AMD, a 1.7% edge.

Multithreaded workloads show a much larger gap. Cinebench R23 multicore delivers an Intel score of 18000 against 11461 for AMD, a 36.3% advantage. Cinebench R15 multicore shows 2464 versus 1712, a 30.5% margin. The PassMark multithread test records 28764 for Intel and 19927 for AMD, a 30.7% difference.

The largest single deltas come from math and physics workloads. PassMark find prime numbers returns 112 for Intel and 62 for AMD, a 44.6% lead. PassMark physics shows the same percentage gap: 1966 versus 1089, also 44.6%. PassMark floating point math records 70640 against 42621, a 39.7% lead. PassMark data encryption shows 19369 versus 11814, a 39% gap. PassMark integer math delivers 97654 versus 63475, a 35% difference. PassMark random string sorting records 36867 versus 25435, a 31% gap. PassMark data compression shows 333785 versus 237484, a 28.9% advantage. The smallest multithreaded gap is in PassMark extended instructions: 20079 versus 17003, a 15.3% lead for Intel.

Specification Differences

The two processors differ across nearly every core specification field. The AMD Ryzen AI 7 345 has 6 cores and 12 threads, a 2.00 GHz base clock, and a 4.60 GHz boost clock. The Intel Core 9 270H has 14 cores and 20 threads, a 2.70 GHz base clock, and a 5.80 GHz boost clock. The Intel part also has a higher TDP at 45 versus 28.

Cache and memory differences are notable. The AMD chip has 1 MB L2 per core and 4 MB total L3, while the Intel chip has 2 MB L2 per core and 24 MB shared L3. The AMD part supports DDR5 and LPDDR5X with a recorded memory bandwidth of 89.6 GB/s; the Intel part supports DDR4 and DDR5 with no memory bandwidth figure in the database. PCIe support differs: AMD uses Gen 4 with 14 CPU lanes, Intel uses Gen 5 with 8 CPU lanes.

Process node and foundry also differ. AMD is on a 4 nm TSMC process; Intel is on a 10 nm process at its own foundry. The integrated graphics differ as well: Radeon 840M on the AMD side, Iris Xe Graphics 96EU on the Intel side. The Intel part has a launch MSRP of $697. The AMD part has no recorded launch MSRP.

Where Each One Wins

The Intel Core 9 270H wins in every measured category, so its use cases are straightforward. It is the stronger choice for any workload that scales with cores and threads, as shown by its 14 cores and 20 threads versus the AMD chip's 6 and 12. The 36.3% Cinebench R23 multicore lead and the 44.6% physics lead indicate strong rendering and simulation performance. The 39% encryption lead and 28.9% compression lead point to advantages in data-heavy tasks. The 39.7% floating point math lead and 35% integer math lead suggest the Intel chip handles computation-heavy applications with significantly more headroom. Even in single-threaded work, where the AMD part is closest, the Intel chip still holds the advantage across all three single-thread benchmarks.

The AMD Ryzen AI 7 345 has no benchmark wins to claim, so its positioning rests on platform-level attributes rather than recorded performance. It uses a 4 nm TSMC process against Intel's 10 nm process, which signals a more advanced manufacturing node. It has a 28 TDP against Intel's 45, which indicates a lower power envelope. It supports LPDDR5X memory and offers 14 PCIe Gen 4 CPU lanes, while the Intel chip offers 8 PCIe Gen 5 lanes. The AMD part also uses the AMD Socket FP8 platform. For a user comparing strictly on the recorded data, the Intel Core 9 270H is the performance winner in all 15 head-to-head tests, and the AMD Ryzen AI 7 345 is the part to consider only when its lower TDP or platform features are the deciding factors.
