AMD Ryzen AI 7 345 vs Intel Core i9-13900H Comparison

The AMD Ryzen AI 7 345 and Intel Core i9-13900H are both mobile processors designed for high-performance laptops, but they employ contrasting architectures and deliver different performance profiles. The AMD part is a 6-core, 12-thread chip based on the Krackan Point design with a 28W TDP, while the Intel part is a 14-core, 20-thread Raptor Lake-H processor with a 45W TDP. In head-to-head testing across 15 benchmark entries, the Intel Core i9-13900H wins 13, while the AMD Ryzen AI 7 345 wins 2, both being the same PassMark single-thread test. However, the AMD chip posts a higher average benchmark score of 29461 versus 28886 for Intel, indicating that its performance profile is not uniformly inferior.

Head-to-Head Benchmarks

The Intel Core i9-13900H dominates the multi-threaded workloads. In Cinebench R23 multi-core, Intel scores 17471 against AMD's 11461, a 34.4% lead. The Cinebench R15 multi-core test shows a similar gap: 2666.5 versus 1712, a 35.8% margin. PassMark's multi-thread test also favors Intel, with 27673 versus 19927, a 28% difference. The gap widens in specific compute tasks. PassMark integer math sees Intel at 97159 versus 63475, a 34.7% lead. Floating point math is even more lopsided: 69611 versus 42621, a 38.8% margin. Physics simulation scores 1745 versus 1089, a 37.6% difference. Data encryption shows Intel at 18974 versus 11814, a 37.7% lead. Prime number finding is the largest gap: 104 versus 62, a 40.4% difference. Data compression also goes to Intel, 326425 versus 237484, a 27.2% lead. Random string sorting is 35637 versus 25435, a 28.6% margin. Extended instructions are closer: 19330 versus 17003, a 12% lead for Intel.

Even in single-core tests, Intel generally leads. Cinebench R23 single-core has Intel at 1964.5 versus 1818, a 7.5% advantage. Cinebench R15 single-core is 279 versus 271, a 2.9% lead. The only exception is PassMark's single-thread test, where AMD scores 3875 against Intel's 3754, a 3.2% win. This is the sole benchmark where the AMD chip comes out ahead.

The magnitude of Intel's wins is substantial. In several tests, the margin exceeds 35%. The AMD chip's single win is narrow, at 3.2%. The data clearly shows that the Intel Core i9-13900H is the stronger performer in the vast majority of the recorded benchmarks. Context from the database's nearest rivals reinforces this. The AMD Ryzen AI 7 345's average score of 29461 is 0.2% higher than the AMD EPYC 9654 and 0.7% higher than the Intel Core i5-13500HX. The Intel Core i9-13900H's average of 28886 is 0.2% higher than the Intel Core i7-12650H and 0.2% lower than the AMD Ryzen 5 5600XT. These comparisons show that while Intel wins most head-to-head tests, the AMD chip holds a higher overall average, likely due to other tests not included in this direct comparison.

Where Each One Wins

The Intel Core i9-13900H is the clear winner for multi-threaded and compute-intensive tasks. Its 14 cores and 20 threads provide a significant advantage in rendering, video encoding, scientific simulations, and any workload that scales with core count. The Cinebench R23 multi-core score of 17471 is 34.4% higher than the AMD's 11461, making it the better choice for content creation and heavy parallel processing. The PassMark multi-thread score of 27673 versus 19927 reinforces this, as does the 38.8% lead in floating point math, which is critical for numerical analysis and 3D rendering. The 40.4% lead in prime number finding and the 37.7% lead in data encryption further underscore Intel's strength in algorithmic and cryptographic workloads.

The AMD Ryzen AI 7 345 wins only the PassMark single-thread test, with a 3.2% edge. This suggests that in a specific single-threaded workload, the AMD chip can outperform the Intel part. However, this is an isolated result. In the Cinebench single-core tests, Intel leads by 7.5% and 2.9% respectively. Therefore, the AMD's single-thread win is not consistent across all single-threaded benchmarks. The AMD chip's higher average benchmark score of 29461, which is 0.2% above the EPYC 9654 and 0.7% above the i5-13500HX, indicates that it may excel in other database tests not part of this head-to-head set. For users who rely on a broad mix of applications, the AMD part could offer a more balanced performance profile, despite losing most direct comparisons.

Architecture Differences

The two processors are built on fundamentally different architectures. The AMD Ryzen AI 7 345 uses the Krackan Point design, part of the Ryzen AI 300 generation based on Zen 5 and Zen 5c cores. It is manufactured on a 4 nm process at TSMC. The Intel Core i9-13900H is a Raptor Lake-H part, from the Core 13th Gen family, built on Intel's 10 nm process. The die size for Intel is 257 mm², while AMD's die size is not recorded.

Core and thread counts differ significantly. AMD has 6 cores and 12 threads, while Intel has 14 cores and 20 threads. This explains Intel's dominance in multi-threaded benchmarks. Clock speeds also favor Intel: base clock of 2.60 GHz versus 2.00 GHz, and boost clock of 5.40 GHz versus 4.60 GHz. The TDP reflects the power envelope: AMD is rated at 28W, Intel at 45W.

Cache hierarchies are distinct. Both have 80 KB of L1 per core, but AMD has 1 MB of L2 per core, while Intel has 2 MB per core. The L3 cache is a major difference: AMD has 4 MB, while Intel has 24 MB shared. This larger L3 cache likely contributes to Intel's performance in data-heavy workloads, as seen in the data compression and random string sorting tests.

Memory support differs. AMD supports DDR5 and LPDDR5X, with a dual-channel bus and a recorded memory bandwidth of 89.6 GB/s. Intel supports DDR4 and DDR5, also dual-channel, but no bandwidth figure is recorded. PCIe connectivity also varies: AMD offers Gen 4 with 14 lanes (CPU only), while Intel offers Gen 5 with 8 lanes. Integrated graphics are present on both: AMD has the Radeon 840M, Intel has Iris Xe Graphics 96EU.

The release dates show a generational gap: AMD launched on 2025-01-14, while Intel launched on 2023-01-03. The Intel part has a launch MSRP of $617.

The Verdict

Based on the recorded benchmark data, the Intel Core i9-13900H is the superior performer in the vast majority of tests. It wins 13 of 15 head-to-head comparisons, with particularly large margins in multi-threaded and compute-intensive workloads. Users who need maximum multi-core performance for tasks like video rendering, 3D modeling, or scientific computing should choose the Intel part. Its 14 cores, 20 threads, and higher clock speeds deliver a 34.4% lead in Cinebench R23 multi-core and a 38.8% lead in floating point math.

The AMD Ryzen AI 7 345, however, is not without merit. It wins the PassMark single-thread test by 3.2%, and its average benchmark score of 29461 is higher than Intel's 28886. This suggests that in a broader set of benchmarks, the AMD chip may perform better on average, even though it loses most of the head-to-head tests. Additionally, its lower TDP of 28W versus 45W indicates a more power-efficient design, which could be important for battery life in thin-and-light laptops.

The choice depends on the workload. For heavy multi-threaded tasks, the Intel Core i9-13900H is the clear winner. For users who prioritize the specific PassMark single-thread test or value the higher average score and lower power envelope, the AMD Ryzen AI 7 345 is a viable alternative. The data does not support a universal recommendation; it supports a workload-specific one.
