AMD Ryzen AI 7 450 vs Intel Core i7-14700 Comparison

Where Each One Wins

The benchmark data splits cleanly along performance classes. The Intel Core i7-14700 wins all 15 recorded head-to-head tests, with margins ranging from a narrow 2% in Cinebench R23 single-core to a dominant 49% in PassMark floating point math. The AMD Ryzen AI 7 450 does not record a single win in the shared test suite. That does not mean the AMD part lacks purpose; its profile is defined by efficiency and mobility rather than raw output.

The Intel part is the clear choice for heavily threaded workloads. Its largest advantages appear in floating point math (49% ahead), prime number finding (45.7% ahead), and data encryption (45.1% ahead). These are compute-intensive tasks that scale with core count and memory throughput. The Intel chip also leads in integer math by 42.7%, data compression by 36.6%, and multi-threaded PassMark by 34.6%. For rendering, the Cinebench R23 multi-core result shows a 35.5% gap in Intel's favor, and the older R15 multi-core test shows a 33.2% gap.

The AMD Ryzen AI 7 450 is a mobile processor with a 28 W TDP, targeting a different segment. Its benchmark scores are lower across the board, but the data places it in the 87th percentile of all CPUs, with an average benchmark score of 39485. That is only 0.3% behind the AMD Ryzen 7 PRO 8840HS and 0.7% behind the AMD Ryzen 7 9800X3D in the nearest rivals list. For a low-power mobile chip, that is a strong showing. The Intel part sits in the 91st percentile with an average score of 52301, which puts it 0.7% ahead of the AMD Ryzen 9 5950X and 0.4% ahead of the Intel Core Ultra 5 235HX.

Single-thread performance is closer. The Intel chip leads by 2% in Cinebench R23 single-core, 7.9% in PassMark single-thread, and 28.1% in Cinebench R15 single-core. The R15 gap is larger, but the newer R23 test suggests the two architectures are much closer in modern single-thread workloads. The Intel part also posts a higher boost clock (5.40 GHz vs. 5.10 GHz), which helps in lightly threaded tasks.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI 7 450 uses the Zen 5 architecture on TSMC's 4 nm process, with a die size of 195 mm². It integrates 8 cores and 16 threads, all based on the Gorgon Point codename, and belongs to the Ryzen AI 400 generation (Zen 5 / Zen 5c). The Intel Core i7-14700 uses the Raptor Lake architecture on Intel's 10 nm process, with a larger die at 257 mm². It packs 20 cores and 28 threads, using the Raptor Lake-R codename and belonging to the Core i7 (Raptor Lake Refresh) generation.

Core counts differ sharply: 8 vs. 20. Thread counts differ even more: 16 vs. 28. The Intel part uses a hybrid design with performance and efficiency cores, which explains its higher thread count per socket. The AMD part uses a unified Zen 5 design with 8 full cores, all capable of simultaneous multithreading.

Cache layouts also diverge. Both share 80 KB of L1 per core. The AMD part has 1 MB of L2 per core, while the Intel part has 2 MB per core. The L3 cache is the biggest difference: the AMD chip has 8 MB total, while the Intel chip has 33 MB shared. That 25 MB gap in L3 is substantial and directly benefits workloads that reuse data sets.

Memory support differs. The AMD chip supports DDR5 and LPDDR5X with dual-channel memory and a measured bandwidth of 89.6 GB/s. The Intel chip supports DDR4 and DDR5 with dual-channel memory, but no bandwidth figure is recorded in the database. Both support ECC memory. PCIe generations differ: the AMD part uses Gen 4 with 16 lanes (CPU only), while the Intel part uses Gen 5 with 16 lanes (CPU only). That gives Intel a bandwidth advantage for storage and expansion.

Integrated graphics are present on both. The AMD chip uses the Radeon 860M, while the Intel chip uses UHD Graphics 770. The database does not record graphics benchmarks for either, so no direct comparison is possible from the data.

Process node and foundry differences are notable. TSMC's 4 nm process for AMD versus Intel's 10 nm process for Intel. The smaller process helps the AMD chip achieve a 28 W TDP, while the Intel chip is rated at 65 W. That is a 37 W difference in thermal design power, which matters for mobile versus desktop deployment.

Head-to-Head Benchmarks

The largest recorded margin is in PassMark floating point math. The Intel Core i7-14700 scores 106716 against the AMD Ryzen AI 7 450's 54447, a 49% advantage. This test stresses FPU throughput, and the Intel part's higher core count and larger cache show clearly.

PassMark find prime numbers shows a 45.7% gap. Intel scores 164, AMD scores 89. This workload is heavily dependent on integer division and memory latency, and the Intel part's 33 MB L3 cache likely reduces memory stalls.

PassMark data encryption shows a 45.1% gap. Intel scores 29601, AMD scores 16247. Cryptographic workloads often use AES-NI and other instruction set extensions; the Intel part's extended instructions score is also higher (28388 vs. 22400, a 21.1% gap).

PassMark integer math shows a 42.7% gap. Intel scores 154535, AMD scores 88531. This is a pure ALU throughput test, and the core count difference dominates.

Cinebench R23 multi-core shows a 35.5% gap. Intel scores 28398, AMD scores 18316. This is a rendering workload that scales well with threads, and the Intel part's 28 threads versus 16 threads explain most of the difference.

PassMark data compression shows a 36.6% gap. Intel scores 498198, AMD scores 315906. Compression algorithms benefit from large caches and memory bandwidth, favoring the Intel part's 33 MB L3.

PassMark multi-thread shows a 34.6% gap. Intel scores 40318, AMD scores 26350. PassMark random string sorting shows a 34.4% gap, with Intel at 54340 and AMD at 35648.

PassMark physics shows a 29.1% gap. Intel scores 2226, AMD scores 1578. Cinebench R15 multi-core shows a 33.2% gap, with Intel at 4061 and AMD at 2713. Cinebench R15 single-core shows a 28.1% gap, with Intel at 299 and AMD at 215.

The closest margins are in single-thread tests. Cinebench R23 single-core: Intel 2080, AMD 2038, only 2% apart. PassMark single-thread: Intel 4236, AMD 3901, a 7.9% gap. These results indicate that the AMD Zen 5 core is competitive with Intel's Raptor Lake core on a per-thread basis, especially in modern workloads.
