Architecture Differences

The AMD Ryzen AI 7 345 is built on a 4 nm process by TSMC and uses the Krackan Point codename. It belongs to the Ryzen AI 300 generation, which combines Zen 5 and Zen 5c cores. The Intel Core i7-14700HX uses Raptor Lake architecture on a 10 nm process by Intel, with the codename Raptor Lake-HX and the Core 14th Gen series designation.

Core configuration differs sharply. The AMD part has 6 cores and 12 threads, while the Intel part has 20 cores and 28 threads. The Intel processor also has a larger die size at 257 mm², whereas the AMD processor has no recorded die size in the database. Both use 80 KB of L1 cache per core, but the Intel part doubles the L2 cache to 2 MB per core versus 1 MB per core on the AMD part. The L3 cache difference is substantial: 33 MB shared on Intel versus 4 MB on AMD.

Memory support diverges as well. The AMD processor supports DDR5 and LPDDR5X with dual-channel memory and a recorded bandwidth of 89.6 GB/s. The Intel processor supports DDR4 and DDR5 with dual-channel memory but has no recorded bandwidth figure. ECC memory is supported on the Intel part but not on the AMD part.

PCIe connectivity differs by generation and lane count. The AMD Ryzen AI 7 345 provides PCIe Gen 4 with 14 CPU lanes, while the Intel Core i7-14700HX provides PCIe Gen 5 with 16 CPU lanes. Integrated graphics also differ: the AMD part uses the Radeon 840M, and the Intel part uses UHD Graphics 770.

The Intel processor has an unlocked multiplier, making overclocking possible at the system level. The AMD processor does not have an unlocked multiplier. The Intel part also has a higher power envelope, rated at 55 W TDP, compared to 28 W for the AMD part.

The Verdict

Benchmark data shows a clear winner in raw performance: the Intel Core i7-14700HX wins all 15 recorded head-to-head benchmarks. Its average score of 45953 places it 56% above the AMD Ryzen AI 7 345's 29461. The Intel part also sits in the 89th percentile versus the AMD part's 81st percentile.

The AMD Ryzen AI 7 345 is the lower-power option, with a 28 W TDP versus 55 W. It also uses a more advanced 4 nm process and supports LPDDR5X memory, which points toward thinner, more power-efficient laptop designs. However, the performance gap is large in every category. In multi-core workloads, the Intel part leads by 53.4% in Cinebench R23 and by 45.5% in PassMark multithread. Even in the closest test, PassMark single-thread, the Intel part still leads by 1.8%.

For workloads that depend heavily on multi-threaded throughput, the Intel Core i7-14700HX is the clear choice from the data. Its 20 cores, 28 threads, and 33 MB of L3 cache deliver decisive advantages in rendering, encryption, compression, and integer math. The AMD part does not win any recorded benchmark, so there is no performance scenario in the database where it comes out ahead.

The AMD Ryzen AI 7 345 may be selected for systems where power draw and memory flexibility matter more than peak performance. Its 28 W TDP and LPDDR5X support suggest a platform designed for efficiency. But the database does not show any benchmark where the AMD part matches the Intel part, so the verdict is straightforward: the Intel Core i7-14700HX dominates the recorded performance metrics.

Head-to-Head Benchmarks

The Intel Core i7-14700HX wins every recorded benchmark, but the margins vary substantially. The closest tests are single-threaded workloads. In PassMark single-thread, the Intel part scores 3947 against 3875 for the AMD part, a delta of 1.8%. The same margin appears in the duplicated PassMark singlethread test. In Cinebench R23 single-core, the Intel part leads by 13.6%, scoring 2103 versus 1818. Cinebench R15 single-core shows a smaller 8.4% gap, with scores of 296 and 271.

Multi-core benchmarks show a much larger separation. Cinebench R23 multi-core is the most decisive: the Intel part scores 24595 versus 11461, a 53.4% lead. Cinebench R15 multi-core follows with a 55.1% gap, scoring 3812 against 1712. The Intel part also records a Cinebench R20 multi-core score of 13059, a test the AMD part does not appear in.

PassMark tests reinforce the multi-core advantage. Data compression shows the Intel part at 438539 versus 237484, a 45.8% lead. Data encryption has the Intel part at 26092 versus 11814, a 54.7% gap. Floating point math shows a 54.6% lead, with 93836 versus 42621. Integer math shows a 51.7% lead, with 131296 versus 63475. Multithread testing shows a 45.5% lead, with 36566 versus 19927. Physics testing shows a 51.6% lead, with 2252 versus 1089. Random string sorting shows a 47.6% lead, with 48544 versus 25435. Extended instructions show a 33.9% lead, with 25718 versus 17003. Find prime numbers shows the largest single-test gap at 62.4%, with 165 versus 62.

Overall, the Intel part's smallest wins are in single-thread tests, where its higher boost clock of 5.50 GHz likely helps. Its largest wins are in multi-threaded and math-heavy workloads, where the 20-core, 28-thread configuration and 33 MB of L3 cache provide a substantial advantage.

Where Each One Wins

The Intel Core i7-14700HX wins in every recorded benchmark category. In rendering workloads, represented by Cinebench multi-core tests, it leads by over 50%. In encryption and compression tasks, it leads by roughly 46% to 55%. In math-heavy workloads such as floating point, integer math, and prime number finding, it leads by 51.7% to 62.4%. In physics simulation and multithreaded throughput, it leads by more than 45%. Even in single-threaded tests, it wins, though by smaller margins of 1.8% to 13.6%.

The AMD Ryzen AI 7 345 does not win any recorded benchmark. Its strongest relative showing is in PassMark single-thread, where it trails by only 1.8%. That result indicates the AMD part can compete in lightly threaded, short-duration tasks, but the data does not show a single scenario where it overtakes the Intel processor.

From the recorded data, the use-case split is therefore one-sided. For any workload that benefits from multiple cores, high thread counts, or large shared cache, the Intel Core i7-14700HX is the stronger option. For workloads that prioritize lower power consumption, the AMD Ryzen AI 7 345 has a 28 W TDP compared to 55 W, and it supports LPDDR5X memory. The database does not include power efficiency benchmarks, so the only advantage attributable to the AMD part from the recorded specifications is its lower TDP and memory type support.
